How To Make A Tnt Cannon In Minecraft Pe

This tutorial is missing information about vertical TNT cannons.

Please expand the tutorial to include this information. Further details may exist on the talk page.

A TNT cannon is a mechanism that uses TNT or minecarts with TNT to launch primed TNT or other entities.

Hither is a video covering some general types of TNT cannons and is a good introduction to them. https://world wide web.youtube.com/sentinel?v=dtgMokm-8IQ

General [ ]

Note: these (as the whole article) talk more often than not about the classical TNT cannons that piece of work by shooting TNT by using other TNT blocks as charge. As of 1.8, it is also possible to build a TNT cannon that works with pistons and slime blocks.

Basic concepts [ ]

TNT cannons operate on the principle that when TNT explodes in water it volition non destroy blocks, but volition even so launch entities, including TNT that was already ignited, which is ordinarily done with redstone (the charge is usually ignited immediately, and then later a delay the shot is released).
The shot is the ammunition; it tin be a player, a mob, a piece of TNT, arrows, sand/gravel or anvils.
If raiding, make sure (unless you lot are using a hybrid TNT cannon) that the shot does non land in water.
The charge is an amount of TNT used to propel the shot.
The accuse (if you are merely playing or testing) should land (TNT volition fall when activated) and explode in water, otherwise the explosion will destroy nearby scenery and damage nearby mobs.
To properly fire an active shot (and avoid destroying your cannon), you need to be sure that your accuse activates before the shot is activated. Since the charge is housed in water it will non destroy your cannon, but the shot is not housed in water when activated, so it will destroy nearby blocks and injure nearby mobs.
Redstone is used to actuate every charge TNT simultaneously with the exception of compressor charges, which are discussed in the advisable department.

TNT cannons tin can too fire upwards to 12 pieces of TNT with a cannon made by Creeperface_33.

For maximum range, you want in that location to be an about 30 caste trajectory but with the least possible amount of matter (blocks) in between the charge and the shot, that way more of the accuse's explosion reaches the shot.
So it's all-time for TNT cannons to be elevated off the ground depending on the wanted range of the cannon.
For shooting arrows, sand/gravel, anvils, or mobs, a piston might exist needed to drop the said ammunition.

Naming standards [ ]

There are 2 types of cannon names: The "common name" gives a picture of what the cannon can do and how easy information technology is to build. The "technical name" gives the specifics of the cannon, like how much filibuster the redstone repeaters have.

Common names [ ]

The common name of a TNT cannon is a curt numerical description followed past the cannon's nickname. Information technology is useful for comparison of two cannons and gives the reader an idea of what the cannon tin exercise at a glance.

The common name of a cannon consists of v parts: the impairment value (DV), the ergonomic value (EV), the TNT amount (TA), the maximum range (MR), and the nickname. They appear in this order:

Case: 40.86:8.104 Bones.

Damage value

Damage values show how "good" a cannon is, the higher the value, the meliorate it is. Information technology is calculated as the average of three values: accuracy, power and speed.

The accuracy value is calculated from the accuracy input, which is the average of the distances from the explosions generated from the shots to the average of their positions.

In the image to the right, the accuracy input is the average of the lengths of the blue lines. The red dot is the average of the positions of the explosions, and an endpoint of each of the blue lines, the others beingness the explosions. The accuracy value equation is (45-A)*2, where "A" is the accuracy input.

The power value is the number of TNT in the shot times x.

The speed input is the distance between the front of the cannon to the average position of the centers of the explosions. The speed value equation is Southward/v, where "Due south" is the speed input.

The damage value is calculated using this equation: (((45 - A)*2) + (P*10) + (S/5)) / iii.

Ergonomic value

Ergonomic value tells how hard a cannon is to build, higher values signifying easier build. Information technology is the average of the structure, redstone, and TNT values.

The construction input is an estimate of the number of blocks in the cannon, excluding fire, water, air, and TNT. The structure value is (1000 - B)/10, assuming "B" is the construction input.

The redstone value is x minus an estimate from one to ten of the complexity of the redstone, times ten; (ten-R)*10, where "R" is the guess.

The TNT value is (50 - T) * 2, and "T" is the number of TNT needed to operate the cannon at maximum capacity.

The whole equation to summate the EV is ((1000 - B)/x + ((10 - R)*x) + ((fifty - T)*two)) / 3.

Other

TNT corporeality, maximum range, and nickname are pretty self-explanatory, simply to clarify, the TA is the aforementioned every bit the TNT value of the EV, and the MR is the distance from the front of the cannon to the uttermost explosion.

The nickname is whatever y'all name information technology, bold information technology's not profane, and nobody else has already named a similar cannon.

This is how the 40.86:viii.104 Basic cannon was named.

Impairment value = (((45 -                      0          )*2) + (            1          *10) + (            104          /five)) / iii = 40 Ergonomic value = ((1000 -                      l          )/10 + ((10 -                      ii          )*10) + ((50 -                      viii          )*2)) / iii = 86                      40          .            80          :            8          .            104                                Bones

Technical names [ ]

A cannon'southward technical proper noun should give its readers a complete picture of its role, use, and method of operation. While it is impossible to anticipate every innovation in TNT cannon technologies, almost cannons will do good from using these standards in their technical names.

The first number in a technical TNT cannon name designates how many horizontal rows(layers) of TNT it has for the charge. The example cannon has 1.
The next number is the amount of shot TNT. Again, the case cannon has one.
Side by side, the number designates how many charge blocks of TNT the cannon has.
If there is a TNT condensation organization, after the accuse number, write a decimal betoken, then the amount of condensation charge TNT. If there is no such TNT, write 0 instead.
A list of how many repeaters at that place are, and how much they are ready to. East.k. If you accept 10 repeaters set to 4 (which is the maximum setting), you would list R4.10. If there are no repeaters, you lot would write an Chiliad for manual.
The mounting block is designated by a code: 0 or 1 for no block, two for full cake, 3 for slab, four for ladder, glass pane, or iron bar, 5 for trapdoor, 6 for argue post and pressure plate, 7 for piston.
If the cannon does something special, like shoot vertically, or does a spread shot, write that after the mounting block code.
The nickname of the cannon goes hither.

The featured TNT cannon above would exist named 114.0R4.4M2.

Edifice materials [ ]

Survival mode [ ]

As discussed in bones concepts, there are many parts of a TNT cannon.

Torso
- Consider using a common material, such equally asphalt.
  - In multiplayer, when firing confronting another cannon, try to apply materials with college nail resistance. (For more on TNT cannon defenses, look below)
- Another cistron is visibility, which is one ordinarily overlooked. When making a cannon out of obsidian, it is hard to see redstone, and that tin atomic number 82 to fatal errors. On the other cease, when setting upward an ambush in the jungle, it is best not to make your cannon out of orange wool or lapis.
Wiring
- In that location are ii main sets of wiring in a cannon, the accuse wiring which activates the charge, and the shot wiring that activates the shot.
  - Without any repeaters, which can be difficult to get, a cannon is designated as manual, with two redstone ability sources/blocks, such as buttons. For a transmission cannon, the materials are simple, just a redstone wire that connects the charge to a redstone emitting detail, and a wire that connects the shot to a redstone power source. Notwithstanding, this requires skill so as non to misfire, you must know when to activate each push button.
  - With repeaters it is a different story. The maximum amount of time between the charge activating and the shot activating is 10 repeaters set to 4. That will as well bring you maximum range, volition only require one redstone ability source, and will require no skill to fire correctly.
Mounting cake
- Mounting blocks (described below) are just certain special blocks.
Explosion housing
- Unless it'south a dry cannon, this must be water or lava (in the latter case, only source blocks). The liquid prevents the cannon and any other surrounding blocks from being destroyed.

Creative mode [ ]

In artistic manner, there is no reason to build a TNT cannon for warfare, but is the optimal style for testing and developing cannons.

Factions [ ]

In factions raiding with TNT cannons is the most common way of getting into a base. There are two principal methods. The showtime (on servers where enabled) is to airburst. This only works on obsidian with water outside. The cannon shot must have a filibuster and so the explosion reaches the obsidian just the primed TNT must not be in the water. These cannons will not piece of work on other walls. The other method is with hybrid cannons which are explained below. The basic hybrid is one of the most commonly used raiding cannons.

Limitations, and means to possibly become effectually them [ ]

The five big, chief limits to TNT cannon engineering, ordered by importance, are:

That no matter what y'all exercise, a TNT will explode approximately 4 seconds or viii flashes after being primed. The mode to sidestep this is to make the TNT wing faster, but that leads us to limit 2.
Minecraft tin only accept and then much, and entities flight at escape velocity around your Minecraft world can cause it to crash. Another thing that can crusade crashes of your Minecraft is big amounts of impulse charges detonating in unison. With the allotted ane.5 GB of RAM, the max TNT is almost 500. The way to possibly sidestep is to increase the RAM allowed for Minecraft, although that is non recommended for lower end computers.
TNT has a 7 cake detonation radius, so only making a large cannon is a waste of time. Beyond 9 charges, the TNT is wasted. However, this can be sidestepped past either calculation more vertical rows of charge to your cannon, adding a charge condensing system to your cannon, or a combination of them both.
TNT flows with the water while in it. This can be skilful or bad, depending on the situation. The manner to sidestep this is to use h2o source blocks, and don't place any TNT inside it.
If y'all make a vertical cannon likewise powerful, information technology will fly up too fast and high significant it volition crash your game. This tin be sidestepped by decreasing the power of said cannon, or making it semi-vertical. That fashion you lot tin can go upward and sideways.

Cannon sizes and special features [ ]

The default definition of cannon size is how many TNT are in the shot or how far information technology fires. If yous are talking virtually compact cannons, yous might be talking almost literally the size of the cannon (e.k. how much space it takes up) or if you are talking about cannons meant for mass destruction, you might be talking about the size of the shot. But usually, people mean accuse mass.

A small-scale cannon, such as a 112.0MM3 cannon, simply has a very pocket-size range, and is meant for stopping large amounts of rushing players or mobs.

A medium cannon, such as the 116.0R4.6M2 is meant for setting upwardly as a first line sieger, to exist set up and aimed at a target such equally supplies or a wall while ane has arrow cover, or to be ready as an anti-archer cannon.

A large cannon, such equally the 119.0R4.10M3 is for attacking from a altitude, a borderline long range mortar, an anti-cannon defense, a second line sieger, and many other uses.

A sniper cannon, such as the 119.3R4.10M6 is for a tent line sieger, setting upwardly to shell opponents camp when they can't even encounter the cannon shelling them, and other out-of-sight range tasks such every bit that.

And of course, mass demo cannons, such as the 187.0MM6 spread-shot, which is used to completely mutilate any defenses whatsoever.

Players likewise similar to add features to their cannons including:

Multiple shots [1]
Semi-automated/fully-automatic firing and reloading [2] [three]
Condenser charge (another set of TNT that explodes, pushing the charge towards the front of the cannon to increase the propulsion force.)
Safety features, such as a blast shield to protect players/mobs from damage caused past the charge exploding
Adjustable shot filibuster
Alternative ammo, such as arrows, sand/gravel, or anvils [4]
Dry cannon: building a cannon from explosion-resistant material to simplify pattern, maintenance, and potentially better firing altitude (dry out cannons fire further than their moisture counterparts, all other factors being the same). Encounter below for construction details.
Cannons that fire in a special direction, such as upward or diagonally
Adaptable range, trajectory and management (aimable cannons)
Spread shot/mass devastation cannons
Shotgun-similar charges

Charge condensing [ ]

TNT-based condensing [ ]

An example cannon with a Condenser Accuse.

A comparison of the shot altitude of two different cannons, 1 shot with and i shot without a condenser charge each.

Because the force from an explosion is weaker the further away from its source, TNT placed more vii blocks from the projectile have little to no effect. To remedy this problem a condenser charge may exist used.

A condenser accuse works by exploding slightly before the principal charge, with the intention to button other primed TNTs towards the projectile. Since the main charge is closer to the projectile, information technology will be launched with more forcefulness.

Piston-based condensing [ ]

Using pistons to push button the main charge closer to the shot as well does the same thing as a condenser accuse, more than complicated to build simply more controllable. To work, the main accuse must be primed, turning the solid TNT blocks into entities. Once they are entities, a series of pistons can push and concentrated all charges into a single cake space behind the shot. In this system, you get far more efficient power from a given size of accuse.[5]

Care must be taken so that the pistons do not displace the water blocks protecting the cannon from TNT damage. To practise this, i unremarkably has to apply h2o a block above the surface area where the pistons would become into. It is also advised that the pistons should retract back into normal position before the main charge explodes, or your cannon might be destroyed. When the pistons extend, they create air spaces in the water no thing what, hence compromising the h2o's protection.

Guide blocks [ ]

When a TNT accuse is primed, information technology will ordinarily shift slightly to one side, which can reduce the accuracy of otherwise well-designed cannons. A simple solution exists: add guide blocks so that there is a wall on either side of the TNT when information technology is primed. This will prevent the TNT from shifting left or right, resulting in a straighter shot, with less diagonal variance. If your blueprint does not allow for this, you could just make the guide blocks one cake higher, instead of being on either side of the TNT. This works because TNT will jump upwards, and then go sideways in midair. Notation that in virtually basic cannons, guide blocks should exist transparent if the TNT cannon automatically primes the shot-otherwise, the redstone that ignites the charge will power the block next to the shot, and igniting the shot as well. If this caption is unclear, await at this diagram:

In dry cannons, a guide block is about a necessity because dry cannons tend to be inaccurate. However, dry cannon's guides are for directing the shot to exist shot accurately, not to exist primed accurately. Withal, guides can also decrease range if they are too long.

Shot mounting blocks [ ]

The shot mounting block for a cannon should be chosen according to how fast, far, and high you desire the cannon to fire. Of form, these variables depend greatly on the position and amount of the charge and the timing of the shot, but the mounting block as well can make a deviation. For example, with a cannon with a charge of 5 and a delay of R4.3, the shot volition take a mortar trajectory with a ladder more with a fence post and pressure plate.

A few things:

Even though the shot mounting blocks ladder and total block are both the same height and fire a shot at the same trajectory, the ladder will consistently burn farther than the full block because the ladder has less matter in between the shot and the charge than the total cake. This state of affairs is the same for all mounting blocks, the slab and argue mail service with force per unit area plate too follow the same dominion.
There is a merchandise off: although the fence post and pressure plate fire the uttermost, they are besides expensive, while the slab is cheap and easy to get, as well as coming in many forms.
The maximum range for any cannon can be achieved by altering the mounting block. A TNT shot will be fired farthest if it leaves the cannon at a 30 caste angle. And then, if you want to just accept your cannon go the farthest it can, use the slab, fence and pressure plate, or trapdoor mounting blocks. However, when faced with fortifications or terrain obstacles, the best idea would exist to accept a mounting block like piston, ladder, or single block that makes the TNT arc over the said obstacle. But, then again, information technology is fun to blast your way through things...
The following shot mounting blocks are tested and deemed safe. Feel free to experiment with mounting blocks, just keep in mind that some blocks, such every bit a lone pressure plate, volition cause a mis fire of your cannon, and of grade make it self-destruct.

A rewrite for about of these mounting blocks is coming shortly.

	Pros	Cons	Notes	Paradigm
No mounting block	Highest velocity, simple, scalable	Poor range in smaller cannons, downward trajectory, line-of-sight just	When no mounting block is used, the shot is launched from the same level as the TNT. It will fire out completely horizontal, or 0°. Gravity will chop-chop pull the shot to the footing, giving a very apartment, down trajectory. With small TNT charges, the range can be extremely limited. To increase the range, ever larger charges are needed or the cannon must be built higher in a higher place the ground. A larger charge means a higher velocity to the shot, pushing it further abroad before it drops to the basis. Players have been known to use up to 70 TNT charges and beyond. But economically, a cannon without a mounting block will take more TNT and longer to load for a certain range.	No Mounting Block
Single block	Higher firing bending, can lob shots	Low velocity, reduced ability and poor range for smaller cannons, and it won't get as far.	A single full size block such every bit cobblestone or obsidian is placed under the Shot. This has the effect of elevating the Shot above the h2o trough, so the blast force from the Accuse is applied not just forward, but up. The shot is fired out at a high angle and trajectory. This is useful for hit an elevated target, or one backside terrain or obstruction. However, part of the blast force is absorbed by a solid mounting block, then the cannon volition suffer similar bug of needing large charge sizes. Too, since some of the free energy is expelled in the upwards direction, forrard shot velocity is reduced greatly. A better alternative to the single mounting block is using a ladder instead.	Unmarried solid mounting block
Slab	Shine trajectory (not too loftier, not also low), average velocity, more efficient for small and medium cannons	Slightly reduced power, not best for either straight or lob shots, fuse range limit*	A slab is the compromise between a unmarried block and no mounting, and mostly more efficient than either. More than of a cannon's blast force is directed frontward, but there is nonetheless an upward vector that raises the angle of fire to roughly thirty°. Every bit with a single cake, some of the blast free energy is absorbed by the cake, but much less. From the same TNT load, the half block has greater range than a unmarried block or no block. When the TNT shot is initially placed over a one-half block, it will hang over it as if it was a full size block. One time the TNT has been "primed", it will fall downwards and sit on the true height of the slab. The firing angle produced past a half block is adept for extending the range of a cannon and hitting elevated targets, but its as well depression for effective lobbing over high walls and obstacles. For straight directly firing, shots fired with a half block mounting generally land level on the footing inside a certain range. However, due to the limited fuse fourth dimension of TNT in the game, scaling up the TNT charges upwards to a point will result in the shot flight too high and exploding in the air before it lands or reach the cannon's maximum range. This will be refer to as the "fuse range limit". All cannons are limited by the fuse range limit, but cannons firing at higher angles are especially prone to the fuse limit, as the shot velocity is lower and shots reach higher altitudes.	Stone slab used as a half block mounting
Trapdoor	Closed: Optimized for flat trajectory, velocity well-nigh the same as no-block, have a very large range pregnant it can destroy far targets.	Be sure that priming circuit doesn't activate the trapdoor by blow. Very loftier speeds and oversized accurate shots could hateful that if the primed TNT hits a nearby wall in the air, it volition fall downwards and miss the shot. It cannot aim at medium or loftier elevated targets	If the firing angle of the half block is too loftier for your purpose, a airtight trapdoor can be used instead. Like the one-half block, information technology provides some upward strength to the shot by elevating it above the trough. A trapdoor'due south height, however, is ³⁄₁₆thursday of a full block. Firing angle is roughly 15-xx°, making information technology extremely effective for straight shots at very long range (180+ blocks). Footling forrard velocity is lost when firing, and shot typically fly out at very high speeds. This combine with the low firing bending means cannons firing larger loads can extend their range without encountering likewise much fuse range problems equally with the one-half block or ladder mounting.	Trapdoor used equally a mounting cake
Trapdoor	Open: Tin exist used in open position for higher firing angle, proficient scaling, can destroy higher targets			Trapdoor used equally a mounting cake
Ladder, Iron bars, Glass pane	Efficient with modest and medium cannons, high firing angle, parabolic trajectory, good for lobbing shots and high altitude.	Depression horizontal speed, poor scaling, express range at ±120 blocks.	A ladder placed on the side can serve as a very effective mounting block for firing at loftier angles and lobbing shots. A primed shot volition exist supported by the edge thickness of the ladder, preventing information technology from falling into the trough. Because a ladder is not a full size cake, none of the energy from the blast is captivated, and the shot is propelled out at full forcefulness. By adding ladders higher up each other, different firing angles can be achieved. Typically, a unmarried ladder volition requite an angle just higher than a half block, roughly 40°-45°. 2 ladders will give an extremely parabolic flight, shots wing out at about 50°-lx°. A good portion of the nail energy is directed upwards on the cake, so horizontal speeds are mostly much slower than a no-mountain or half block mountain cannon. In return, the cannon has no problem lobbing shots over terrain and walls. At larger charge loads, shots tin achieve very high altitudes. Withal, this besides means the fuse range limit is an inherent trouble with this mounting. Inside a 100 block distance, well built cannons level with the ground can await to land shots depression enough to crusade impairment. Only beyond this shots explode midair manner beforehand, even with a shot primed at maximum fuse time with a filibuster circuit. Hence, one can't only add more TNT to increment the range, as it volition merely brand the shot wing college. A bones solution is to put the cannon below basis, in a pit with a slanted slope to let the shot to wing out. Since the shot had a lower starting point, it will explode closer to the ground once its fuse time runs out. To reach ranges beyond 150 blocks, this solution becomes impractical.	Ladder mounting block Shot mounting with two ladders
Debate	Efficient with minor and medium cannons, low firing angle, skilful for shooting through caves and past overhanging base defenses. Loftier velocity, extremely powerful in spread cannons and long range cannons.	Expensive materials, fuse range limit to bigger cannons. If used a condenser, then the explosion will send the TNT too loftier and with no ceiling, the TNT tin destroy the cannon.	A fence placed at the finish of the cannon tricks Minecraft to recollect that it is one block high, since it is but one and a one-half block high for the player's perspective. Therefore, the charge would be recognized every bit closer to the shot than it actually is. Since information technology gains more ability and velocity, it appears to fly up a bit, then go down in an attack bending. However, the explosion launches the TNT upwards pregnant if the cannon has no ceiling, the TNT tin can well destroy the cannon. This gives it a distinctive style of cannon shooting, and it is considered one of the well-nigh useful mounting blocks in Minecraft. if the cannon needs the water blocked a pressure level plate may be used, but slightly decreases the launch velocity.
Piston	Adjustable, when fully extended it has the same effects of a full block but is more efficient than it and is more than versatile, compatible with firing sand or gravel.	Expensive, the shot has been subject to the fuse range delay limit establish in arcing cannons, is used as a mortar MB so usage inside caves or buildings is not recommended and will result in short range shots, accidentally placing ii TNT blocks (one on top of the other) volition destroy the cannon, requires a R4.vii delay.	The three nearly mutual ways to apply this mounting block are Prime the shot then push button it up Push it upwards and then prime number the shot Just use it as a more efficient version of the full block MB.	A TNT cannon with piston mounting.
Rarely used mounting blocks
Blossom pot	Can lob shots.	Fuse range limit, expensive, cannot aim at lower targets
Redstone repeater	Second highest velocity.	Can only shoot ix blocks, expensive, brand sure the circuit doesn't activate it by accident.	This cannon is only used in an extreme hills biome. It only works if the cannon is on a cliff and the target is below information technology.
Daylight sensor	Good shooting, not likewise high velocity, can lob shots.	Make sure the sensor doesn't activate the excursion by accident by daylight, expensive.	This is a cannon for ground levels and it is expert on whatsoever blazon of cannon (except of super large cannons which has a fuse range limit.)
Bed	Skillful shooting, really fast, medium-high bending.	Expensive, bigger cannon	This is expert for attacking bigger castles, but has also a large range. One of the all-time mounting blocks.
Cake	Practiced shooting, medium angle, big range.	Expensive, cannot be retrieved.	This mounting cake is skilful for attacking far targets if you have resources. Information technology has smaller footprint which ways that charge TNT can be closer to the shot than when using slabs, thus increasing the range.
Brewing Stand	Loftier burn angle (similar to ladder), exceptional range, high velocity	Expensive, ineffective against level targets	Brewing Stands will shoot TNT slightly slower (and lower) than a ladder, simply the divergence doesn't show easily. Also allows you to brew regeneration potions while yous shoot to help you recover the recoil damage.
Enchantment Tabular array	High blast resistance, capable of hitting all distances.	Very expensive.	Enchantment Tables burn shots a lot like slabs. Do note that the rotating book will non have whatever consequence on the trajectory.
Stairs	High fire angle	Low velocity	Inverted stairs are useless; mounting a shot on ane has a very high run a risk of blowing up your cannon and/or diggings the nearby landscape.

Cannon tutorials [ ]

Dispenser-based cannons [ ]

An example cannon using dispensers

Note: the case cannon needs modifications to work in Bedrock Edition because dispensers even so make TNT hop ending up with the offset TNT destroying the machine. This tin can be fixed past putting that dispenser on a separate water menstruum that goes into the same block, also allowing for long range cannons.

Since the Redstone Update, redstone dispensers dispense ignited TNT instead of dropping it. This feature can be used to brand better automatic TNT cannons.

The cannon to the correct uses dispensers to release TNT into the water. When you press the button, first the long row of dispensers will fire. Later a 33-tick delay made the repeaters, leftmost dispenser will dispense the last moment earlier the TNT detonates, giving the shot a longer range. Annotation that the leftmost dispenser is college than the other dispensers, and that the water should exist flowing towards the front end of the cannon. Dispensers manipulate TNT without the feature "hop" of ignited TNT, which helps ensure the TNT will state in a much shorter radius than a conventional TNT cannon.

One of the smallest TNT cannons is this design by Mumbo Jumbo:

You tin can easily change information technology to have another dispenser under the h2o facing upwards, and you tin employ a fence mail service with a force per unit area plate on peak instead of a slab.

Pros: The fourth dimension taken to reload TNT is at its accented minimum. All a histrion has to practice is to brand sure the side by side shot is placed later on the starting time shot is fired to make sure y'all don't destroy your cannon. This cannon requires little skill at all to burn down; the hardest part will be placing the cannon a proper distance away to make certain y'all don't over/under-shoot. Such precision makes this cannon adept for castle defense. Furthermore, through apply of comparators, it is possible to make an easily aim-able dispenser-based cannon, and dispenser-based cannons do not accident themselves upwards if hit with another TNT cannon.

Cons: Dispensers and TNT are expensive. This blazon of cannon tin never exist quite equally hardy equally transmission cannons, since dispensers can be diddled up with TNT. Furthermore, if the cannon is left loaded and unattended, information technology is fiddling to steal the TNT from its magazine. (This is also true of conventional auto-cannons.) Dispenser-based cannons with a 1-cake-wide water pool have also been known to accident themselves up, particularly if left firing automatically and unattended.

An automatic cannon tin easily exist made with this design. Substitute the button for redstone and hook the redstone upwards to a clock. Be careful not to set the clock under 4 seconds, the same fourth dimension every bit it would accept the TNT to explode. If the TNT is reloaded too quickly, the timing can cause the shot to detonate earlier the propellant does, destroying the entire cannon.

Reloading cannons [ ]

Traditional [ ]

Reloading cannons are 1 of the most complex designs for beginners. Notwithstanding, every bit long as close attention is paid, for a first fourth dimension build, information technology can be created in about xv–twenty minutes depending on the size. Reloading cannons became obsolete when dispensers were added (except in the console editions).

The Expert: Reloading TNT cannons can be customized just as hands equally any other cannon (using fences, atomic number 26 bars, drinking glass panes, etc.). They can be shot several times with just a few seconds' interval in opposition to having to reload it several times like yous'd take to practise with a standard TNT cannon. Using the simple blueprint, this TNT cannon can have up to 12 rounds in the mag. If playing a fortress war server, this cannon tin can burn repeated shots which volition annihilate the enemies' buildings before they accept time to stuff their ammunition into their puny and junior weapons.

The Bad: Unfortunately, cannons of this variety are bulky and oft unattractive. They require sand or gravel which are nonrenewable resources in survival fashion. Added to that, it is boring to reload the cannons whenever the magazines run out of ammo, even so occasional that may be. With standard TNT cannons, if the one-round mag is destroyed, information technology is usually easily replaceable. This is not the case with the reloading kind, as the entire magazine will explode, destroying the weapon and all the redstone wiring with it—often killing you in the procedure. This type of cannon has also become redundant with the recent updates assuasive automatic cannons utilizing dispensers to reload the tnt, which is easier and more compact to brand.

Step 1. Brand the framework. Brainstorm with a standard design, merely make a few modifications so that it looks like this. (Framework)
Then, you should go out a saucepan of water and pour it down the slot like you would with any other design. Make sure to place a cake hovering over the source block and so you lot won't accidentally place something in information technology.
Toss in the wiring and yous should become...
…this!
Pace 2. Make the mag. This is where the TNT is going to be pushed and loaded into the firing chamber. It tin store up to 12 rounds, but this ane will be fabricated with 7. Now we demand to add pistons that will push the TNT towards the chamber, then place this following
By the stop of that, the cannon should await like this.
Stride 3. Work on the chamber. It's important to dissever the chamber and magazine wiring from the TNT.
This weird design should go right in a higher place the sleeping room.
Now we're going to adhere pistons to it that will shove the TNT into place
An aerial view...
Step 4. Connect the sleeping room and magazine wiring. Add this to the framework
And the wiring...
Step 5. Make a trigger. Become to this surface area.
Next, we demand to replace redstone dust with a repeater.
Nosotros're almost done! Just identify the igniter, now.
Footstep 6. Affect up & bank check for issues. I purposefully planted a few problems. First, some of the wiring is in the way of the barrel which will severely damage the range. We'll get to that afterwards. More chiefly, we need to move one of the repeaters ahead because it isn't providing enough power from where it is. Step 7. Load the magazine. Pay close attention to this part as you lot will accept to practice it every time yous reload the magazine. Identify the TNT into the mag, from against the side-pushing pistons...
…to the top-correct edge of the chamber (NOT underneath the downwardly-facing pistons, but right backside that expanse).
Now we need to put sand within the magazine. Y'all'll have to practice this every time, as well. Put viii stacks on top of the TNT pushed against the left-facing pistons.
And there you go! This is what you should see.
Footstep 8. Finish up. Yes, yes, I promised to gear up the wiring in the way of the bedchamber. Here'due south the problem.
This is how y'all set up it. It's relatively simple. Make certain there're no more blocks in the style and you should become this when you burn.
This is the event of fixing the stuff in the way.
You may also want to put in a mount (as mentioned in a previous tutorial) to maximize performance! Hither'due south a glass pane mountain.
Additionally, consider covering the hull of the cannon to foreclose opposing TNT cannons from blowing yours upwards!
Whatever y'all do, just brand sure there'due south a door that leads to the magazine and that the sand-chamber is accessible from the summit so you can reload it!
Ane more thing you can add is this piston. It will pull away the down-facing accuse piston and so that it isn't in the fashion when information technology'south firing. And… that nearly wraps this tutorial up! Experiment with the cannon and exam to see what mounts fit your needs. Make sure to pull the ammunition out of the magazine earlier yous exam blindly—I can imagine it wouldn't exist much fun to watch something that took this long to build fly to pieces!

Dispenser reloading [ ]

In gild to avoid having to manually place TNT into every dispenser of a cannon, some more modernistic cannons have been designed to use a minecart or hopper organisation in gild to distribute a large stack of TNT from 1 location such as a chest into all of a cannon's dispensers. There are issues to using such systems, primarily that nearby minecarts may break if the cannon's charge is likewise powerful, and the necessary redstone circuitry and hopper designs may be deemed too large or complex to exist practical.

The Chaosrider blueprint for the 112.0R1.2R4.1M6 Reloading WOLF uses minecarts and hoppers in a compact and semi-efficient manner:

Short-middle range cannons [ ]

Cannon [ ]

You will demand: xiv building blocks, 4 dispensers, 4 redstone dust, vi redstone repeaters, 1 bucket of water, i push button, 1 fence, i pressure plate and at least iv TNT.

Build a U-shaped frame using building blocks and dispensers, 1 block above the ground. It should exist vi blocks long and 3 blocks wide and the dispensers should be facing towards the center of the U shape.
Add 3 blocks to the front of the U-shape. These will help guide the vanquish. Now add together a last dispenser, facing towards the cavalcade of blocks.
Add iii blocks in the centre of the U-shape, one block lower than information technology.
Identify a contend post and a pressure plate in front of the cannon, and then add water running towards the pressure plate.
Put redstone grit over the two dispensers (you volition take to hold down shift key to do this) then over the furthest dispenser, put a block on top of it and and so put a button on acme of that block.
Finally, add Redstone repeaters to the remaining spaces and put redstone dust on the conners. Every redstone repeater has a 4-tick delay except the Redstone repeater pointing to the upper dispenser.
Finally, fill all iv dispensers with TNT and give it a effort!

Super Quick Raid Cannon [ ]

Pros: Very simple

Cons: No water ways terrain damage. Tin damage you a lot. Requires a bow

This cannon only requires a flame bow, 2 arrows, and eight TNT (though yous'll want to utilise either h2o or adept armor). This was made past reddit user Zecon 365 here

"The Pulverizer" - An Ultra Rapid Automatic Slime Cannon [ ]

A uncomplicated and compact cannon that tin can cause massive destruction. It utilizes an extremely quick timer to dispense and propel the primed TNT with the help of a slime block.

Vertical TNT cannon [ ]

This is a simple TNT cannon to rebuild. It is very efficient and shoots you lot very high in the air.

Vertical TNT cannon (view on YouTube)

Downward TNT Cannon [ ]

This cannon has very few uses, but tin can be used instead of a gravity fed TNT dropper.

3x9 Pressure level Plate [ ]

Pros: easy to build, understand, and use

Cons: any mob tin accidentally use

This cannon requires h2o, redstone, any cake, TNT, and pressure level plates. Make a 9x3 rectangle, intermission the centre of a 3 on one side, and put 2 more than blocks on both sides of the hole, straight up on the blocks. Cascade water into the other side, and place TNT everywhere simply source, and betwixt the highest blocks. Make stairs down 1 side of the high areas, place redstone on the stairs, i block away, and then add together a pressure plate. Place redstone along the frame until yous get to the high points. Put three redstone past the far corner past the stairs, and place some other force per unit area plate. Stride on that, await a count of iii or 4 secs, then go step on the other plate. The loftier TNT will fly out upwardly to nearly 50-60 blocks.

Notation: The water source neutralizes the lower TNT to prevent destruction.

1-button defensively ranged cannon [ ]

Repeater used as delay [ ]

It is a simple cannon that has an automated filibuster. Used generally for guinea pigging other, larger, prototypical cannons or as wall mounted defense force against basis- based troops or artillery.

114.0R4.4MB2 - The naming system for it can be constitute above.

Starting time build the base of the cannon
And so fill it with water on one side
Build two blocks like on the picture
Place the button
Place the redstone wires on one side
On the other side, place a redstone torch and four repeaters on highest filibuster
At the front place another cake with a torch on the side
load the cannon like this...
...and finish.

Minecart used equally delay [ ]

Once yous actuate the switch, first information technology activates the charge wiring, so sends a minecart around the cannon that triggers a detector rail, which primes the shot. Saves redstone, but takes a lot of iron (Withal, if you go rails from abased mineshafts this pattern can even save yous resources!).

Minecart delay (view on YouTube)

Dispenser used as filibuster [ ]

Once you actuate the switch, beginning it activates the charge wiring, and then shoots an item out of a dispenser that will slowly autumn downwards through a pressure plate on a debate and burn down. Saves redstone, and requires no repeaters for those survival cannon engineers, Over all, it'due south cheaper than the design to a higher place and normal automated delay cannons with repeaters used every bit a filibuster.

Human (or other entity) launching cannon [ ]

One time this cannon is set up, then it tin can be used in order to launch entities onto other objects or areas of the map. It can exist a little difficult nonetheless to become the entity inside the cannon,if it's something other than a homo. (this can be done by putting the entity in a minecart and using runway to get it in)

Man launching cannon (view on YouTube)

Ender cannon [ ]

This type of cannon is easily constructed, very powerful (practically infinite) still flexible with its charge and hilarious to picket unfold. The only downsides are that it requires an active ender portal and y'all will need to be in artistic to survive maximum charge. It operates on the principle that the fuse timer on primed TNT is reset to 0 when it passes through an cease portal. This means that a potentially infinite amount of TNT tin can be used every bit a charge, merely past condensing it into 8 blocks of space. Minecraft will not detonate them until yous are in the end, thus making the computer itself the limiting function.

Vertical launcher [ ]

This cannon, oftentimes chosen vertical launcher, other times called "Fireworks cannon" can be used to launch TNT blocks vertically, so that they tin can explode whilst midair.

Vertical launcher (view on YouTube)

Long range cannons [ ]

For long range cannons it is best to use a cannon with multiple rows of TNT for the charge, and depending on the acme of your cannon, playing around with mounting blocks helps. If you add multiple shot TNT to your cannon, and play effectually with where you place the TNT in your cannon, and then you can finer destroy annihilation in the cannons path.

3X3 TNT Minecart Cannon. https://www.reddit.com/r/Minecraft/comments/7w4qsr/3x3_tnt_cannon_with_adjustable_range/dtxfx1b/

Anvil "Baseball" cannon 1280M3ANVIL Cheaper Cannon that uses 8 Accuse Pieces of TNT to launch one to ii anvils upward to 75 blocks on Ground Level and Farther at a Higher Superlative Is Built past simply Wiring up Eight Dispensers to a Single Lever without a Delay and a H2o Stream moving towards the two Anvils that are Hand loaded over an Upward Water Column that, If washed Right, volition cause the Anvils to Jump up and Downwards, the Cannon casing should contain a Slab preventing the TNT from Reaching the H2o Column and a Basic Surrounding example. To burn Pull the Lever once when Both anvils are Staying low on the Water Column, By the time the TNT fires the one anvil will exist leaping High, and if it is at the Apex of it's Leap, Volition be Launched High into the Atmosphere and out of Sight. The Cannon gets the Baseball proper name due to the Similarities between it and Trying to hitting a Ball floating on a Jet of Air with a bat. Currently Working on Adapting it to Launch TNT.

You lot tin can likewise endeavour TNT missiles. They get infinitely long until they hit a block in their path. Then every bit long as you load the chunk they fly in, yous can launch a missile from any distance and hit a target if you lot aim correctly.

Exploit cannons [ ]

Ticking clamper cannons [ ]

In vanilla minecraft, chunks are sorted by level propagation(Come across "Clamper"). In ticking chunks with level propagation of 32, or "lazy loaded chunks", tnt entities won't be loaded. Thus, tnt entities in lazy loaded chunk won't be ticked untill players leaves his electric current chunk. We can stack tnt in lazy loaded chunk and it won't explode or move, which will help united states of america to make super long distance tnt cannons with FTL speed.

A sample video(Not english): TheSailor's 300k entity cannon with speed of 8924m/s

Some other sample video(Non english): xxld0'south ticking chunk end pearl cannon with speed of 510M(yeah 510 one thousand thousand)m/s

It is besides possible to apply this exploit to command tnt directions more than percisely.

Video:ps017 's infinite tnt cannon

Bow bomb cannons [ ]

The harm of arrows are calculated past the speed of arrow(Run into "pointer" page). Arrows can also exist acclerated by tnt explosions, which gives them a boost in damage. If tnt are correctly placed, arrows can be acclerated into whatever speed. An pointer with speed college than 800m/s is able to deal 200 damage in one shot.

Brand sure all the dispensers face up into the barrel of the gun and call up that only the kickoff water block at the back is a source cake.
Also by using pipes of hoppers attached to the backs of the dispensers, one can more easily distribute stacks of TNT from a central betoken, such equally a chest.
Feel free equally always to amend the design. Happy hunting!

Specialized cannons [ ]

Launcher Cannon [ ]

Launcher Pads [ ]

A launchpad is similar in design to a TNT cannon, but instead of launching horizontally, information technology launches vertically either straight up or at an bending, depending on the blueprint. There are many means to create them, but some methods are more efficient than others. For instance, a unproblematic design would be the cross pattern, as shown beneath.

This is what information technology would look similar from above:

To load it, identify TNT on the flowing water blocks.

The above design can easily be expanded in size and improved, but it is one of the easiest designs to build. Some other simple design, yet much more powerful, is here:

YouTube Video (view on YouTube)

Another powerful design, using dispensers to place the TNT is congenital as following:

Layer 1
Layer 2
Layer 3
Layer 4
Layer 5

The dark blocks on the final two on the correct represent dispensers, facing the center. If yous desire this to be reusable, place a water source between them. A pressure level plate delay is enough for each dispenser to shoot twice. An interactive version is here: [vii]

Aerial TNT Dropper [ ]

Every bit of Minecraft 1.5, dispensers now dispense ignited TNT. Thus, downwards-facing dispensers tin pelting TNT on anything under information technology.

Pros: This is a neat manner to bomb enemy bases without retaliation. TNT cannons cannot fire straight up, or risk blowing themselves up. It tin can hands blow its manner to bedrock. In bases with water over them, sand tin exist dropped from above.

Cons: This cannon is useless in factions servers which accept block protection over bases, every bit this requires this to be directly in a higher place the base. It is extremely resources-heavy, as so much TNT is used. This has less range than a downward facing TNT cannon.

This trap is very unproblematic: Go upward high, build a platform, place dispensers downward, set a clock, and watch as your enemy'due south base is obliterated. Simply block-pillar up to a proficient height. Exercise not build besides high, equally the TNT would explode in midair, uselessly. Build the platform direct over the target. Identify dispensers and make full them with TNT. Set a Clock circuit to trigger the dispensers, but be conscientious! Setting the speed too fast will take the waves of TNT literally launch upwardly and destroy your cannon. You lot can mine the dispensers later. As to the problem of getting back downwardly, you could utilise water, just Ender Pearls could come in handy.

Anti-water defence cannon [ ]

It fuses sand and TNT together to blow up blocks covered with water. H2o is the enemy of TNT cannons, and this 1 works around it.

Anti-water defence force cannon (view on YouTube)

Aim-able T gun [ ]

This cannon is shaped like a T; the way it works is that it drops the shot in vertically on top of a mounting blocks between 2 smaller troughs that can be filled with TNT to alter the shot'due south horizontal launch bending. You tin adjust the range by non filling the main trough all the mode. Great for putting in a castle to destroy enemy artillery!

Simple T-Gun Tutorial

Arrow cannon [ ]

An arrow cannon technically does the same chore as a dispenser just with greater range and area-of-outcome. The general way to brand these is to have a piston extended over where the mounting block on a normal cannon would be. This would be hooked to a repeater cord exactly nine repeaters long, so inverted to go along the piston extended. The residuum is only the charge trough, wired up like a normal cannon. Then apply a bow to eolith arrows on the piston head, load the charge trough, and press the button. What happens is: right before the TNT explodes, the piston retracts making the arrows fall. Then the TNT goes off, launching the arrows long distances. This cannon is unremarkably used in generally mid-range scenarios where harm to blocks is unwanted.

Here's another design:

The cannon displayed uses a delay to break the sand on the upper-front and advance the arrows. Beneath the showtime image is a tiptop view.

Sand cannon [ ]

Sand cannons are a variation of the TNT cannon that is harmless. The concept is the same, but uses sand equally a projectile. Likewise, the sand must exist falling as the TNT in the cannon explodes, shooting the sand, otherwise, zilch happens. Information technology is possible to pile the sand up to make a "sand shotgun cannon", which can fire multiple sand blocks at different distances. Note that the sand cannon generally but fires in one direction and is not destructive. Information technology can exist used for pelting sand at people'south plots in creative multiplayer plots servers, and in turn, making moderators mad. Sand cannons are also normally used by griefers on multiplayer servers. While the victim is doing renovations on their claimed land, griefers may build a sand cannon as quick as possible as to not being defenseless, and burn several blocks of sand to the superlative of the victim's business firm while they are doing construction in hopes that they volition break a block on their roof and have sand fall on summit of them.

Sand falls at a different speed than TNT does. Every bit a event, it isn't possible to make a TNT-sand variable cannon that uses sand to determine where the cannon will launch its TNT to. However, it will fire the sand at the same horizontal angle if using an aimable cannon.

To build a sand cannon, use a piston to push the sand off in front end of the TNT charge, or a sticky piston attached to an inverter to remove a block holding the sand upward.

Note: Sand is not the merely matter that can exist used. Anything that falls tin can be used, and this includes:

Gravel
Anvil
Dragon egg

Notation that anvils and dragon eggs will not exist pushed by pistons, and so only the second method described in a higher place for building will work for said blocks.

Dry out cannons [ ]

A dry out cannon uses TNT to launch TNT (or fifty-fifty the user on artistic mode). Dry cannons are simple, piece of cake to build and effective just require lots of obsidian or other blast-resistant materials.

The master difference betwixt a dry out cannon and other designs is the lack of water and the use of a wadding block.

The charge is a large amount of TNT that propels the shot. All of these TNT blocks must be ignited simultaneously.
The wadding cake can be any type of block (except obsidian, bedrock and whatever other blast-resistant blocks) and provides a buffer between the accuse and the shot. Sand, snow, wool and other soft blocks seem to produce the all-time effects.
The shot is a block of TNT or the user if yous are on creative fashion and drop into position on time.

Vertical cannon [ ]

This blueprint is a vertical cannon but tin can be turned horizontally as well.

The cannon is built entirely of obsidian.

Start by building a 5x5x4 rectangular prism, leaving a 3x3x2 chamber inside.
Make a pigsty in the top center of the prism.
Identify 1 slice of obsidian on the eye block at the lesser of the bedroom. This is the mounting block.
Load bottom layer of chamber with TNT. This is the charge.
Place the wadding on top of the mounting block.
Identify the shot on the wadding.
Provide a redstone excursion so all the charge blocks are activated simultaneously.
Stand dorsum and throw the switch!

Horizontal cannon [ ]

Brand a long tube of obsidian (works best with 3x3x6 or 3x3x7) with a hollow heart. Then, put two blocks of obsidian on the top. Hollow it out. Fill with TNT, and put an non-blast resistant block in the last space on the front. Cover the meridian with redstone, and identify a button on the back. Optionally, brand a platform to stand on when you trigger it. You should also brand it a little ways off the ground. Encounter diagram below, in which the orange stands for the wadding (shown in cutaway side view):

Information technology volition launch several blocks of TNT at your target, however it is expensive and does not have a very long range, but with a big cannon, y'all can shred a large amount of land with each shot. Occasionally the redstone will exist blasted off if you have a big cannon, so it is skilful to keep some redstone on hand. Good for the defense of a village (smash mobs with a row of cannons when they come too close!). Best for artistic fashion due to the large amount of TNT needed for each shot.

TNT catapults [ ]

Slime blocks, introduced in ane.8, tin can bounciness entities to certain heights. They can also push other blocks with them when pushed by pistons. These machines make use of this concept to make TNT catapults.

Pros

They are very cheap to build.
They are decently long ranged and fire in an arc.
They use much less TNT than other cannons of their skill.
They can be fired extremely rapidly.

Cons

It can exist hard to obtain the pistons and slime blocks needed.
The catapult has a stock-still target and limited range.

TNT lifter [ ]

A TNT cannon might shoot TNTs far abroad, just not high up. this blueprint uses an ordinary cannon, but uses slime blocks to launch information technology higher.

Video examples [ ]

Mortar - High angle shot using a ladder mounting cake.
Compact - The shot is primed by hand, which must at present be done with flintstone and steel
Super large cannon - Firing other entities.

Trivia [ ]

TNT cannon firing is the most random event in Minecraft, because of thousands of different sample points taken to make up one's mind dozens (or even hundreds) of different vectors which are and then added together to form the base trajectory of a shot. Nevertheless, it is possible to make some cannons, specially vertical mortars, 99% accurate (the charge falls back into the barrel and detonates at a specific height).
If yous're really lazy and accept operator privileges (or in singleplayer with cheats), y'all tin just use commands or command blocks instead. The command /summon minecraft:tnt ~ ~2 ~ {Fuse:12,Movement:[ane.0,0.0,0.0]} will fling a lit TNT eastward, starting from simply to a higher place your head.
TNT cannons tend to fire further when facing east or due south.
