General [ ]

Note: these (every bit the whole commodity) talk mostly nigh the classical TNT cannons that work by shooting TNT by using other TNT blocks as charge. Every bit of 1.8, it is also possible to build a TNT cannon that works with pistons and slime blocks.

Bones concepts [ ]

TNT cannons operate on the principle that when TNT explodes in h2o it will not destroy blocks, but will nevertheless launch entities, including TNT that was already ignited, which is usually washed with redstone (the charge is usually ignited immediately, then later a delay the shot is released).
The shot is the ammunition; it can be a role player, a mob, a slice of TNT, arrows, sand/gravel or anvils.
If raiding, brand sure (unless yous are using a hybrid TNT cannon) that the shot does not land in h2o.
The accuse is an amount of TNT used to propel the shot.
The charge (if you are just playing or testing) should land (TNT will fall when activated) and explode in water, otherwise the explosion volition destroy nearby scenery and damage nearby mobs.
To properly burn an active shot (and avoid destroying your cannon), yous need to be sure that your charge activates before the shot is activated. Since the charge is housed in water it will non destroy your cannon, only the shot is not housed in water when activated, so information technology will destroy nearby blocks and injure nearby mobs.
Redstone is used to activate every accuse TNT simultaneously with the exception of compressor charges, which are discussed in the advisable section.

TNT cannons tin besides fire up to 12 pieces of TNT with a cannon fabricated by Creeperface_33.

For maximum range, y'all want there to be an about thirty degree trajectory but with the least possible amount of matter (blocks) in betwixt the accuse and the shot, that way more of the charge's explosion reaches the shot.
And then it'southward best for TNT cannons to be elevated off the basis depending on the wanted range of the cannon.
For shooting arrows, sand/gravel, anvils, or mobs, a piston might be needed to drop the said ammunition.

Naming standards [ ]

There are 2 types of cannon names: The "common name" gives a motion-picture show of what the cannon can practice and how easy it is to build. The "technical proper name" gives the specifics of the cannon, like how much delay the redstone repeaters have.

Mutual names [ ]

The mutual name of a TNT cannon is a short numerical description followed past the cannon'southward nickname. It is useful for comparison of 2 cannons and gives the reader an thought of what the cannon can practice at a glance.

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

Case: 40.86:8.104 Basic.

Damage value

Harm values prove how "proficient" a cannon is, the higher the value, the improve it is. It 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 epitome to the right, the accuracy input is the average of the lengths of the blueish lines. The red dot is the average of the positions of the explosions, and an endpoint of each of the blue lines, the others being the explosions. The accuracy value equation is (45-A)*2, where "A" is the accuracy input.

The ability value is the number of TNT in the shot times ten.

The speed input is the distance betwixt the front of the cannon to the boilerplate position of the centers of the explosions. The speed value equation is Due south/five, where "South" is the speed input.

The damage value is calculated using this equation: (((45 - A)*2) + (P*10) + (S/five)) / 3.

Ergonomic value

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

The construction input is an guess of the number of blocks in the cannon, excluding fire, water, air, and TNT. The construction value is (g - B)/10, bold "B" is the construction input.

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

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 calculate the EV is ((1000 - B)/ten + ((ten - R)*10) + ((50 - T)*ii)) / 3.

Other

TNT amount, maximum range, and nickname are pretty self-explanatory, but to analyze, the TA is the same as the TNT value of the EV, and the MR is the altitude from the front of the cannon to the farthest explosion.

The nickname is whatever you lot proper noun information technology, bold it'southward not profane, and nobody else has already named a similar cannon.

This is how the xl.86:viii.104 Basic cannon was named.

Harm value = (((45 -          0)*2) + (1*10) + (104/5)) / 3 = 40 Ergonomic value = ((1000 -          50)/10 + ((10 -          two)*ten) + ((fifty -          8)*2)) / iii = 86          40.eighty:8.104          Basic

Technical names [ ]

A cannon's technical proper noun should give its readers a complete picture show of its function, use, and method of operation. While it is impossible to anticipate every innovation in TNT cannon technologies, most cannons will benefit from using these standards in their technical names.

The first number in a technical TNT cannon proper noun designates how many horizontal rows(layers) of TNT it has for the accuse. The example cannon has 1.
The next number is the amount of shot TNT. Again, the instance cannon has 1.
Next, the number designates how many charge blocks of TNT the cannon has.
If in that location is a TNT condensation system, subsequently the accuse number, write a decimal indicate, and then the amount of condensation accuse TNT. If there is no such TNT, write 0 instead.
A list of how many repeaters there are, and how much they are set to. E.g. If y'all take 10 repeaters set to four (which is the maximum setting), you would list R4.x. If there are no repeaters, you would write an Thousand for transmission.
The mounting block is designated by a code: 0 or 1 for no block, 2 for total block, 3 for slab, 4 for ladder, glass pane, or iron bar, 5 for trapdoor, half dozen for fence 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 lawmaking.
The nickname of the cannon goes here.

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

Building materials [ ]

Survival mode [ ]

As discussed in basic concepts, at that place are many parts of a TNT cannon.

Torso
- Consider using a common textile, such every bit asphalt.
  - In multiplayer, when firing against another cannon, try to use materials with higher blast resistance. (For more on TNT cannon defenses, look below)
- Another factor is visibility, which is 1 commonly overlooked. When making a cannon out of obsidian, information technology is hard to meet redstone, and that can atomic number 82 to fatal errors. On the other finish, when setting upwardly an ambush in the jungle, information technology is best not to brand your cannon out of orange wool or lapis.
Wiring
- There are two primary sets of wiring in a cannon, the charge wiring which activates the charge, and the shot wiring that activates the shot.
  - Without any repeaters, which can be hard to become, a cannon is designated equally manual, with two redstone power sources/blocks, such equally buttons. For a manual cannon, the materials are unproblematic, just a redstone wire that connects the charge to a redstone emitting item, and a wire that connects the shot to a redstone power source. However, this requires skill so equally non to misfire, you must know when to activate each button.
  - With repeaters it is a different story. The maximum amount of time between the charge activating and the shot activating is ten repeaters set up to four. That will besides bring yous maximum range, will just require 1 redstone ability source, and volition require no skill to fire correctly.
Mounting block
- Mounting blocks (described below) are only certain special blocks.
Explosion housing
- Unless it's a dry cannon, this must be water or lava (in the latter example, merely source blocks). The liquid prevents the cannon and any other surrounding blocks from beingness destroyed.

Artistic mode [ ]

In creative mode, at that place is no reason to build a TNT cannon for warfare, only is the optimal mode for testing and developing cannons.

Factions [ ]

In factions raiding with TNT cannons is the nigh common fashion of getting into a base. There are 2 principal methods. The start (on servers where enabled) is to airburst. This only works on obsidian with water outside. The cannon shot must have a delay so the explosion reaches the obsidian but 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 bones hybrid is one of the most unremarkably used raiding cannons.

Limitations, and ways to perchance get effectually them [ ]

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

That no matter what y'all do, a TNT volition explode approximately four seconds or 8 flashes subsequently existence primed. The way to sidestep this is to brand the TNT fly faster, but that leads us to limit two.
Minecraft tin merely take and then much, and entities flying at escape velocity around your Minecraft earth can cause it to crash. Another affair that can cause crashes of your Minecraft is big amounts of impulse charges detonating in unison. With the allotted i.5 GB of RAM, the max TNT is virtually 500. The way to possibly sidestep is to increase the RAM allowed for Minecraft, although that is not recommended for lower end computers.
TNT has a 7 cake detonation radius, and so just making a big cannon is a waste product of time. Beyond 9 charges, the TNT is wasted. All the same, this tin be sidestepped by either adding more vertical rows of charge to your cannon, adding a charge condensing arrangement to your cannon, or a combination of them both.
TNT flows with the h2o while in information technology. This can be expert or bad, depending on the situation. The mode to sidestep this is to use water source blocks, and don't place any TNT inside it.
If you lot make a vertical cannon also powerful, it will wing upwardly besides fast and high meaning it volition crash your game. This can exist sidestepped by decreasing the power of said cannon, or making it semi-vertical. That way you can go up and sideways.

Cannon sizes and special features [ ]

The default definition of cannon size is how many TNT are in the shot or how far it fires. If you are talking about compact cannons, you might be talking about literally the size of the cannon (e.g. how much space it takes up) or if you are talking most cannons meant for mass destruction, you lot might be talking near the size of the shot. But usually, people mean charge mass.

A small cannon, such every bit a 112.0MM3 cannon, only 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 up every bit a first line sieger, to be set up and aimed at a target such every bit supplies or a wall while one has pointer cover, or to be fix as an anti-archer cannon.

A large cannon, such as 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 every bit the 119.3R4.10M6 is for a tent line sieger, setting up to shell opponents army camp when they tin't even meet the cannon shelling them, and other out-of-sight range tasks such as 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 like to add features to their cannons including:

Multiple shots [ane]
Semi-automatic/fully-automatic firing and reloading [2] [iii]
Condenser charge (another set of TNT that explodes, pushing the charge towards the front end of the cannon to increase the propulsion forcefulness.)
Rubber features, such as a blast shield to protect players/mobs from damage caused by the accuse exploding
Adjustable shot filibuster
Alternative ammo, such equally arrows, sand/gravel, or anvils [4]
Dry cannon: building a cannon from explosion-resistant material to simplify design, maintenance, and potentially improve firing distance (dry cannons burn further than their wet counterparts, all other factors being the same). Meet below for construction details.
Cannons that fire in a special management, such as up or diagonally
Adaptable range, trajectory and management (aimable cannons)
Spread shot/mass devastation cannons
Shotgun-similar charges

Accuse condensing [ ]

TNT-based condensing [ ]

An instance cannon with a Condenser Charge.

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

Considering the force from an explosion is weaker the further away from its source, TNT placed more than 7 blocks from the projectile have niggling to no event. To remedy this problem a condenser charge may be used.

A condenser charge works by exploding slightly before the main charge, with the intention to push other primed TNTs towards the projectile. Since the main charge is closer to the projectile, it will be launched with more than force.

Piston-based condensing [ ]

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

Intendance must be taken then that the pistons do not displace the h2o blocks protecting the cannon from TNT damage. To do this, ane usually has to apply water a block above the area where the pistons would go into. It is as well 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 matter what, hence compromising the h2o's protection.

Guide blocks [ ]

When a TNT charge 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 together guide blocks so that in that location is a wall on either side of the TNT when information technology is primed. This will foreclose the TNT from shifting left or correct, resulting in a straighter shot, with less diagonal variance. If your design does not allow for this, you lot could just make the guide blocks one block higher, instead of being on either side of the TNT. This works because TNT will jump up, and so go sideways in midair. Notation that in most 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 side by side to the shot, and igniting the shot as well. If this explanation is unclear, look at this diagram:

In dry cannons, a guide block is almost a necessity because dry out cannons tend to exist inaccurate. However, dry out cannon's guides are for directing the shot to be shot accurately, non to exist primed accurately. However, guides can too decrease range if they are besides long.

Shot mounting blocks [ ]

The shot mounting block for a cannon should be chosen co-ordinate to how fast, far, and high yous 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 too can brand a deviation. For example, with a cannon with a charge of 5 and a filibuster of R4.3, the shot will take a mortar trajectory with a ladder more than than with a fence mail and pressure level plate.

A few things:

Even though the shot mounting blocks ladder and full block are both the same peak and fire a shot at the same trajectory, the ladder will consistently fire farther than the total block considering the ladder has less affair in betwixt the shot and the charge than the full block. This state of affairs is the same for all mounting blocks, the slab and fence post with pressure plate also follow the same dominion.
In that location is a trade off: although the fence postal service and pressure plate burn down the farthest, they are also expensive, while the slab is cheap and easy to get, as well equally coming in many forms.
The maximum range for any cannon tin exist achieved by altering the mounting block. A TNT shot volition exist fired farthest if it leaves the cannon at a 30 caste angle. So, if you want to just accept your cannon get the farthest it tin can, use the slab, fence and pressure level plate, or trapdoor mounting blocks. All the same, when faced with fortifications or terrain obstacles, the best idea would be to have a mounting block similar piston, ladder, or single block that makes the TNT arc over the said obstacle. Simply, and then again, it is fun to nail your way through things...
The following shot mounting blocks are tested and accounted safety. Feel gratuitous to experiment with mounting blocks, merely proceed in mind that some blocks, such as a lone pressure plate, will cause a mis burn of your cannon, and of class brand it self-destruct.

A rewrite for most of these mounting blocks is coming soon.

	Pros	Cons	Notes	Epitome
No mounting block	Highest velocity, unproblematic, scalable	Poor range in smaller cannons, downward trajectory, line-of-sight simply	When no mounting cake is used, the shot is launched from the same level every bit the TNT. It volition fire out completely horizontal, or 0°. Gravity volition quickly pull the shot to the basis, giving a very flat, downwards trajectory. With modest TNT charges, the range can be extremely express. To increase the range, ever larger charges are needed or the cannon must be built higher above the ground. A larger accuse means a higher velocity to the shot, pushing it farther away before it drops to the ground. Players have been known to use up to lxx TNT charges and across. But economically, a cannon without a mounting cake will accept more TNT and longer to load for a sure range.	No Mounting Block
Unmarried cake	College firing angle, tin lob shots	Depression velocity, reduced power and poor range for smaller cannons, and information technology won't go as far.	A single full size block such as cobblestone or obsidian is placed under the Shot. This has the effect of elevating the Shot in a higher place the h2o trough, and then the blast forcefulness from the Accuse is applied not just forrad, but up. The shot is fired out at a loftier angle and trajectory. This is useful for hitting an elevated target, or one behind terrain or obstacle. However, part of the blast forcefulness is absorbed by a solid mounting block, and so the cannon volition suffer similar problems of needing large charge sizes. As well, since some of the energy is expelled in the upwards direction, frontward shot velocity is reduced greatly. A better alternative to the single mounting block is using a ladder instead.	Single solid mounting block
Slab	Shine trajectory (not too high, non also low), average velocity, more efficient for pocket-sized and medium cannons	Slightly reduced power, not all-time for either straight or lob shots, fuse range limit*	A slab is the compromise betwixt a single block and no mounting, and generally more efficient than either. More of a cannon's smash forcefulness is directed frontwards, but there is still an upward vector that raises the angle of fire to roughly 30°. As with a single block, some of the smash energy is absorbed by the block, just much less. From the aforementioned TNT load, the half block has greater range than a unmarried cake or no cake. When the TNT shot is initially placed over a half cake, information technology will hang over it as if it was a total size block. Once the TNT has been "primed", it will fall down and sit down on the truthful height of the slab. The firing angle produced by a half block is adept for extending the range of a cannon and hitting elevated targets, only its too low for constructive lobbing over high walls and obstacles. For direct straight firing, shots fired with a half block mounting generally land level on the ground within a sure range. However, due to the limited fuse time of TNT in the game, scaling up the TNT charges up to a point will consequence in the shot flight too high and exploding in the air before information technology lands or reach the cannon'due south 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 peculiarly prone to the fuse limit, as the shot velocity is lower and shots accomplish higher altitudes.	Stone slab used as a half block mounting
Trapdoor	Airtight: Optimized for flat trajectory, velocity almost the same as no-block, have a very large range meaning information technology can destroy far targets.	Be sure that priming circuit doesn't actuate the trapdoor by accident. Very loftier speeds and oversized accurate shots could mean that if the primed TNT hits a nearby wall in the air, it will fall downwards and miss the shot. Information technology cannot aim at medium or high elevated targets	If the firing angle of the half block is too high for your purpose, a closed trapdoor can be used instead. Like the half block, it provides some upward force to the shot past elevating it in a higher place the trough. A trapdoor's tiptop, nevertheless, is ³⁄₁₆th of a full block. Firing bending is roughly 15-twenty°, making information technology extremely effective for direct shots at very long range (180+ blocks). Footling frontwards velocity is lost when firing, and shot typically wing out at very high speeds. This combine with the depression firing bending ways cannons firing larger loads tin extend their range without encountering too much fuse range issues as with the half block or ladder mounting.	Trapdoor used as a mounting cake
Trapdoor	Open: Can be used in open up position for higher firing angle, expert scaling, can destroy higher targets			Trapdoor used as a mounting cake
Ladder, Atomic number 26 bars, Glass pane	Efficient with small and medium cannons, high firing angle, parabolic trajectory, good for lobbing shots and loftier altitude.	Low horizontal speed, poor scaling, limited range at ±120 blocks.	A ladder placed on the side tin serve as a very constructive mounting cake for firing at high angles and lobbing shots. A primed shot will be supported by the edge thickness of the ladder, preventing information technology from falling into the trough. Because a ladder is not a full size block, none of the energy from the blast is absorbed, and the shot is propelled out at full forcefulness. Past calculation ladders higher up each other, different firing angles can be achieved. Typically, a single ladder will give an bending simply higher than a half block, roughly xl°-45°. Two ladders will requite an extremely parabolic flight, shots fly out at about 50°-lx°. A good portion of the nail energy is directed upwards on the cake, and then horizontal speeds are generally much slower than a no-mountain or half block mount cannon. In return, the cannon has no problem lobbing shots over terrain and walls. At larger charge loads, shots tin can reach very high altitudes. However, this also means the fuse range limit is an inherent problem with this mounting. Within a 100 block distance, well built cannons level with the basis can expect to land shots depression enough to crusade damage. But beyond this shots explode midair mode beforehand, even with a shot primed at maximum fuse time with a delay circuit. Hence, i can't simply add more than TNT to increase the range, as it volition only make the shot fly higher. A basic solution is to put the cannon beneath ground, in a pit with a slanted slope to allow the shot to fly out. Since the shot had a lower starting point, information technology 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
Fence	Efficient with pocket-size and medium cannons, depression firing angle, good 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 volition transport the TNT also high and with no ceiling, the TNT can destroy the cannon.	A fence placed at the stop of the cannon tricks Minecraft to call up that it is ane block high, since it is simply 1 and a half cake loftier for the player's perspective. Therefore, the accuse would be recognized as closer to the shot than it really is. Since it gains more power and velocity, it appears to fly up a bit, then become down in an attack bending. However, the explosion launches the TNT upwards pregnant if the cannon has no ceiling, the TNT tin well destroy the cannon. This gives information technology a distinctive manner of cannon shooting, and it is considered 1 of the most useful mounting blocks in Minecraft. if the cannon needs the h2o blocked a pressure plate may be used, but slightly decreases the launch velocity.
Piston	Adjustable, when fully extended information technology has the same furnishings of a full block only is more efficient than information technology 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 equally a mortar MB so usage inside caves or buildings is not recommended and will issue in short range shots, accidentally placing 2 TNT blocks (one on top of the other) will destroy the cannon, requires a R4.vii filibuster.	The three near mutual ways to use this mounting block are Prime the shot so push it up Push button it upward and so prime number the shot Just use it every bit a more efficient version of the full block MB.	A TNT cannon with piston mounting.
Rarely used mounting blocks
Flower pot	Tin lob shots.	Fuse range limit, expensive, cannot aim at lower targets
Redstone repeater	Second highest velocity.	Can only shoot nine blocks, expensive, make certain 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 beneath it.
Daylight sensor	Good shooting, not too loftier velocity, can lob shots.	Brand sure the sensor doesn't activate the excursion past blow by daylight, expensive.	This is a cannon for basis levels and information technology is proficient on any type of cannon (except of super large cannons which has a fuse range limit.)
Bed	Good shooting, really fast, medium-high angle.	Expensive, bigger cannon	This is good for attacking bigger castles, simply has also a big range. One of the best mounting blocks.
Cake	Good shooting, medium angle, big range.	Expensive, cannot exist retrieved.	This mounting block is proficient for attacking far targets if you lot have resources. It has smaller footprint which means that accuse TNT tin can exist closer to the shot than when using slabs, thus increasing the range.
Brewing Stand up	High fire angle (similar to ladder), infrequent range, high velocity	Expensive, ineffective confronting level targets	Brewing Stands volition shoot TNT slightly slower (and lower) than a ladder, but the difference doesn't show hands. Also allows you to brew regeneration potions while you shoot to help you lot recover the recoil damage.
Enchantment Tabular array	Loftier blast resistance, capable of striking all distances.	Very expensive.	Enchantment Tables burn down shots a lot like slabs. Practice note that the rotating book will non have any effect on the trajectory.
Stairs	High fire angle	Low velocity	Inverted stairs are useless; mounting a shot on ane has a very high chance of blowing up your cannon and/or blasting the nearby mural.

Dispenser-based cannons [ ]

An instance cannon using dispensers

Note: the example cannon needs modifications to work in Boulder Edition because dispensers still make TNT hop ending up with the first TNT destroying the auto. This can be fixed past putting that dispenser on a separate h2o flow that goes into the same block, too allowing for long range cannons.

Since the Redstone Update, redstone dispensers manipulate ignited TNT instead of dropping it. This characteristic can exist used to brand better automatic TNT cannons.

The cannon to the right uses dispensers to release TNT into the water. When you press the push button, first the long row of dispensers will fire. Later on a 33-tick delay made the repeaters, leftmost dispenser will dispense the last moment before the TNT detonates, giving the shot a longer range. Annotation that the leftmost dispenser is higher than the other dispensers, and that the water should be flowing towards the front of the cannon. Dispensers dispense TNT without the characteristic "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 can easily modify it to take another dispenser nether the h2o facing up, and you tin can utilize a fence post with a pressure plate on peak instead of a slab.

Pros: The time taken to reload TNT is at its absolute minimum. All a player has to exercise is to make certain the next shot is placed after the start shot is fired to make certain you lot don't destroy your cannon. This cannon requires little skill at all to fire; the hardest part will exist placing the cannon a proper altitude away to brand certain you don't over/under-shoot. Such precision makes this cannon good for castle defense. Furthermore, through utilise of comparators, it is possible to make an easily aim-able dispenser-based cannon, and dispenser-based cannons practise not accident themselves up if hit with another TNT cannon.

Cons: Dispensers and TNT are expensive. This type of cannon tin never be quite as hardy every bit manual cannons, since dispensers can be blown upwardly with TNT. Furthermore, if the cannon is left loaded and unattended, information technology is lilliputian to steal the TNT from its magazine. (This is likewise truthful of conventional auto-cannons.) Dispenser-based cannons with a 1-block-broad water puddle accept also been known to blow themselves upwards, specially if left firing automatically and unattended.

An automated cannon can easily be made with this design. Substitute the button for redstone and hook the redstone up to a clock. Be careful not to set up the clock under iv seconds, the aforementioned time equally it would take the TNT to explode. If the TNT is reloaded as well quickly, the timing can cause the shot to detonate before the propellant does, destroying the unabridged cannon.

Reloading cannons [ ]

Traditional [ ]

Reloading cannons are 1 of the nigh complex designs for beginners. However, as long equally close attending is paid, for a first time build, it can be created in about xv–20 minutes depending on the size. Reloading cannons became obsolete when dispensers were added (except in the console editions).

The Good: Reloading TNT cannons can exist customized just as easily equally whatsoever other cannon (using fences, iron bars, glass panes, etc.). They can exist shot several times with only a few seconds' interval in opposition to having to reload it several times similar you lot'd take to exercise with a standard TNT cannon. Using the simple design, this TNT cannon can have up to 12 rounds in the magazine. If playing a fortress war server, this cannon can fire repeated shots which will 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 often unattractive. They require sand or gravel which are nonrenewable resources in survival mode. Added to that, it is tedious to reload the cannons whenever the magazines run out of ammo, nonetheless occasional that may be. With standard TNT cannons, if the 1-circular magazine is destroyed, it is commonly easily replaceable. This is not the case with the reloading kind, every bit the entire magazine will explode, destroying the weapon and all the redstone wiring with it—ofttimes killing yous in the process. This type of cannon has also get redundant with the recent updates allowing automatic cannons utilizing dispensers to reload the tnt, which is easier and more compact to make.

Step 1. Make the framework. Begin with a standard design, merely brand a few modifications so that it looks like this. (Framework)
Then, yous should become out a bucket of water and pour it down the slot like you would with any other pattern. Make certain to place a block hovering over the source cake and then you won't accidentally place something in information technology.
Toss in the wiring and you should go...
…this!
Step 2. Make the magazine. This is where the TNT is going to be pushed and loaded into the firing chamber. It can shop up to 12 rounds, but this one volition be made with 7. Now we demand to add together pistons that will push the TNT towards the chamber, so identify this following
By the end of that, the cannon should look like this.
Step iii. Work on the chamber. Information technology'south of import to separate the chamber and magazine wiring from the TNT.
This weird design should go right above the chamber.
Now nosotros're going to attach pistons to it that will shove the TNT into place
An aeriform view...
Stride 4. Connect the chamber and magazine wiring. Add this to the framework
And the wiring...
Step 5. Make a trigger. Go to this area.
Next, we need to supercede redstone dust with a repeater.

We're near washed! Just place the igniter, now.

Pace 6. Bear on upwardly & check for issues. I purposefully planted a few problems. First, some of the wiring is in the way of the butt which will severely damage the range. We'll get to that later. More chiefly, we demand to move one of the repeaters ahead because information technology isn't providing enough power from where it is. Step 7. Load the magazine. Pay close attention to this role every bit you volition have to practice it every time yous reload the mag. Place the TNT into the magazine, from against the side-pushing pistons...

…to the superlative-right edge of the chamber (Not underneath the down-facing pistons, but right behind that area).

At present nosotros need to put sand within the mag. You'll take to do this every time, too. Put 8 stacks on top of the TNT pushed confronting the left-facing pistons.

And there you go! This is what you should see.

Step 8. Finish up. Yes, aye, I promised to fix the wiring in the style of the chamber. Here's the trouble.

This is how yous prepare it. It'southward relatively simple. Make certain there're no more blocks in the way and you should get this when you fire.

This is the consequence of fixing the stuff in the way.

Y'all may likewise want to put in a mountain (as mentioned in a previous tutorial) to maximize performance! Here's a glass pane mount.

Additionally, consider covering the hull of the cannon to foreclose opposing TNT cannons from blowing yours up!

Whatever y'all practise, just make certain there'south a door that leads to the magazine and that the sand-chamber is attainable from the elevation then you can reload it!

One more thing you lot tin add is this piston. It will pull away the down-facing charge piston so that it isn't in the way when information technology's firing. And… that well-nigh wraps this tutorial upwardly! Experiment with the cannon and exam to see what mounts fit your needs. Brand sure to pull the ammunition out of the mag earlier you lot test blindly—I tin can imagine information technology wouldn't exist much fun to spotter something that took this long to build wing to pieces!

Dispenser reloading [ ]

In order to avoid having to manually place TNT into every dispenser of a cannon, some more modern cannons accept been designed to use a minecart or hopper organization in order to distribute a large stack of TNT from 1 location such every bit a chest into all of a cannon'south dispensers. At that place are issues to using such systems, primarily that nearby minecarts may break if the cannon'southward charge is besides powerful, and the necessary redstone circuitry and hopper designs may be accounted too big or complex to exist practical.

The Chaosrider design 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 edifice blocks, 4 dispensers, iv redstone dust, 6 redstone repeaters, 1 bucket of h2o, one push, ane argue, ane pressure plate and at to the lowest degree 4 TNT.

Build a U-shaped frame using building blocks and dispensers, 1 block above the ground. Information technology should be 6 blocks long and 3 blocks wide and the dispensers should be facing towards the centre of the U shape.
Add 3 blocks to the front of the U-shape. These will assistance guide the trounce. At present add together a concluding dispenser, facing towards the cavalcade of blocks.
Add together 3 blocks in the center of the U-shape, 1 block lower than it.
Place a fence mail and a force per unit area plate in front of the cannon, and so add h2o running towards the pressure level plate.
Put redstone grit over the 2 dispensers (you will have to hold down shift key to do this) then over the furthest dispenser, put a block on pinnacle of information technology and and then put a button on elevation of that block.
Finally, add Redstone repeaters to the remaining spaces and put redstone grit on the conners. Every redstone repeater has a iv-tick filibuster except the Redstone repeater pointing to the upper dispenser.
Finally, fill all four dispensers with TNT and give information technology a attempt!

Super Quick Raid Cannon [ ]

Pros: Very elementary

Cons: No water means terrain harm. Tin harm you a lot. Requires a bow

This cannon only requires a flame bow, two arrows, and 8 TNT (though you'll desire to use either water or good armor). This was fabricated past reddit user Zecon 365 here

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

A unproblematic and compact cannon that can cause massive destruction. Information technology utilizes an extremely quick timer to dispense and propel the primed TNT with the help of a slime cake.

Vertical TNT cannon [ ]

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

Vertical TNT cannon (view on YouTube)

Downwardly TNT Cannon [ ]

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

3x9 Force per unit area Plate [ ]

Pros: like shooting fish in a barrel to build, understand, and apply

Cons: any mob can accidentally use

This cannon requires water, redstone, any block, TNT, and pressure plates. Make a 9x3 rectangle, interruption the middle of a 3 on one side, and put ii more than blocks on both sides of the hole, straight up on the blocks. Pour water into the other side, and place TNT everywhere but source, and between the highest blocks. Make stairs downward ane side of the high areas, place redstone on the stairs, 1 cake away, then add a pressure plate. Place redstone along the frame until you get to the high points. Put iii redstone past the far corner by the stairs, and place another pressure level plate. Step on that, wait a count of iii or 4 secs, then go step on the other plate. The high TNT will fly out upward to nigh fifty-60 blocks.

Note: The h2o source neutralizes the lower TNT to prevent devastation.

1-button defensively ranged cannon [ ]

Repeater used as delay [ ]

It is a simple cannon that has an automatic delay. Used by and large for guinea pigging other, larger, prototypical cannons or as wall mounted defence against ground- based troops or artillery.

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

Start build the base of operations of the cannon
Then fill it with water on one side
Build 2 blocks similar on the film
Place the button
Place the redstone wires on one side
On the other side, place a redstone torch and four repeaters on highest delay
At the front place another block with a torch on the side
load the cannon like this...
...and finish.

Minecart used as delay [ ]

Once you activate the switch, kickoff it activates the charge wiring, then sends a minecart around the cannon that triggers a detector rail, which primes the shot. Saves redstone, just takes a lot of atomic number 26 (Even so, if yous become rail from abandoned mineshafts this blueprint can fifty-fifty relieve you resources!).

Minecart delay (view on YouTube)

Dispenser used as delay [ ]

Once y'all activate the switch, first it activates the accuse wiring, then shoots an item out of a dispenser that will slowly fall downward through a pressure level plate on a argue and burn. Saves redstone, and requires no repeaters for those survival cannon engineers, Over all, it's cheaper than the design above and normal automated filibuster cannons with repeaters used as a delay.

Dispenser delay (view on YouTube)

Homo (or other entity) launching cannon [ ]

In one case this cannon is gear up, then it can exist used in order to launch entities onto other objects or areas of the map. Information technology can be a little difficult however to become the entity inside the cannon,if it's something other than a human. (this can exist done by putting the entity in a minecart and using rail to get it in)

Human launching cannon (view on YouTube)

Ender cannon [ ]

This type of cannon is easily synthetic, very powerful (practically infinite) still flexible with its charge and hilarious to sentry unfold. The only downsides are that it requires an active ender portal and you lot will need to be in artistic to survive maximum charge. Information technology operates on the principle that the fuse timer on primed TNT is reset to 0 when it passes through an end portal. This means that a potentially infinite amount of TNT can be used as a accuse, simply by condensing information technology into 8 blocks of space. Minecraft will not detonate them until yous are in the end, thus making the computer itself the limiting office.

Vertical launcher [ ]

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

Long range cannons [ ]

For long range cannons it is best to utilize a cannon with multiple rows of TNT for the accuse, and depending on the pinnacle of your cannon, playing effectually with mounting blocks helps. If you add together multiple shot TNT to your cannon, and play effectually with where you place the TNT in your cannon, then you tin effectively destroy anything 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 Eight Charge Pieces of TNT to launch 1 to 2 anvils up to 75 blocks on Ground Level and Further at a College Elevation Is Congenital by simply Wiring upwardly Eight Dispensers to a Single Lever without a Delay and a H2o Stream moving towards the ii Anvils that are Hand loaded over an Up Water Column that, If washed Right, will cause the Anvils to Jump upwardly and Down, the Cannon casing should contain a Slab preventing the TNT from Reaching the Water Cavalcade and a Bones Surrounding case. To fire Pull the Lever once when Both anvils are Staying depression on the Water Cavalcade, By the time the TNT fires the ane anvil will exist leaping Loftier, and if it is at the Noon of it'due south Jump, Will exist Launched Loftier into the Atmosphere and out of Sight. The Cannon gets the Baseball name due to the Similarities between it and Trying to hit a Brawl floating on a Jet of Air with a bat. Currently Working on Adapting it to Launch TNT.

You can likewise endeavour TNT missiles. They go infinitely long until they hit a block in their path. And then as long as you load the chunk they wing in, you can launch a missile from whatever distance and striking a target if you aim correctly. Hither is a classic minecraft missile: https://www.youtube.com/watch?5=O-HA--BKuOs

This is a very complex blueprint that is capable of selecting seven ranges. It is also capable of firing in semi-auto, full-car and 3-round burst like the H&K MP5 submachine gun.

RailCannon Pattern [ ]

A simple design using a bug with TNT minecarts, using multiple minecarts to simultaneously explode causing projectiles to be launched into the air. This cannon uses less TNT than traditional methods previous of 1.v and launches projectiles much further.

Make sure all the dispensers face into the barrel of the gun and remember that only the first water block at the back is a source block.
Besides past using pipes of hoppers attached to the backs of the dispensers, one can more than easily distribute stacks of TNT from a central point, such equally a chest.
Feel free as always to improve the design. Happy hunting!

Specialized cannons [ ]

Launcher Cannon [ ]

Launcher Pads [ ]

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

This is what information technology would look similar from above:

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

The above blueprint can easily be expanded in size and improved, but it is 1 of the easiest designs to build. Another elementary design, notwithstanding much more powerful, is here:

YouTube Video (view on YouTube)

Another powerful blueprint, using dispensers to identify the TNT is built as post-obit:

Layer 1
Layer two
Layer iii
Layer four
Layer 5

The dark blocks on the last two on the right stand for dispensers, facing the centre. If yous desire this to be reusable, place a water source between them. A pressure plate filibuster is enough for each dispenser to shoot twice. An interactive version is here: [7]

Aerial TNT Dropper [ ]

As of Minecraft 1.5, dispensers at present dispense ignited TNT. Thus, downward-facing dispensers can pelting TNT on anything nether information technology.

Pros: This is a great fashion to bomb enemy bases without retaliation. TNT cannons cannot fire straight up, or risk blowing themselves up. It can hands accident its mode to bedrock. In bases with h2o over them, sand can exist dropped from above.

Cons: This cannon is useless in factions servers which have block protection over bases, as this requires this to be directly above the base. Information technology is extremely resource-heavy, as and then much TNT is used. This has less range than a downwards facing TNT cannon.

This trap is very simple: Go upwards high, build a platform, place dispensers downward, set a clock, and sentinel equally your enemy's base is obliterated. But block-colonnade upward to a good height. Do non build besides loftier, as the TNT would explode in midair, uselessly. Build the platform directly over the target. Place dispensers and fill them with TNT. Prepare a Clock excursion to trigger the dispensers, just be careful! Setting the speed besides fast will have the waves of TNT literally launch upward and destroy your cannon. Yous tin can mine the dispensers afterward. As to the problem of getting dorsum down, you could use water, but Ender Pearls could come up in handy.

Anti-h2o defense cannon [ ]

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

Anti-water defense cannon (view on YouTube)

Aim-able T gun [ ]

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

Unproblematic T-Gun Tutorial

Arrow cannon [ ]

An arrow cannon technically does the same task equally a dispenser just with greater range and area-of-effect. The general mode 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 9 repeaters long, and then inverted to go on the piston extended. The rest is simply the charge trough, wired up like a normal cannon. And then use a bow to eolith arrows on the piston head, load the accuse trough, and press the push button. What happens is: right before the TNT explodes, the piston retracts making the arrows fall. So the TNT goes off, launching the arrows long distances. This cannon is commonly used in by and large mid-range scenarios where damage to blocks is unwanted.

Here'southward another design:

The cannon displayed uses a delay to break the sand on the upper-front and accelerate the arrows. Below the showtime image is a superlative view.

Sand cannon [ ]

Sand cannons are a variation of the TNT cannon that is harmless. The concept is the same, just uses sand every bit a projectile. Also, the sand must be falling as the TNT in the cannon explodes, shooting the sand, otherwise, nothing happens. It is possible to pile the sand upwards to brand a "sand shotgun cannon", which tin can fire multiple sand blocks at unlike distances. Note that the sand cannon generally merely fires in one direction and is not subversive. Information technology tin can exist used for pelting sand at people's plots in creative multiplayer plots servers, and in turn, making moderators mad. Sand cannons are also commonly used past griefers on multiplayer servers. While the victim is doing renovations on their claimed land, griefers may build a sand cannon as quick as possible every bit to not being caught, and fire several blocks of sand to the top of the victim's house while they are doing construction in hopes that they volition break a cake on their roof and have sand fall on top of them.

Sand falls at a different speed than TNT does. As a consequence, it isn't possible to make a TNT-sand variable cannon that uses sand to determine where the cannon volition launch its TNT to. However, information technology volition fire the sand at the aforementioned horizontal angle if using an aimable cannon.

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

NOTE: Sand is non the just matter that can be used. Anything that falls can exist used, and this includes:

Gravel
Anvil
Dragon egg

Notation that anvils and dragon eggs will not exist pushed by pistons, so merely the second method described above for edifice will work for said blocks.

Dry cannons [ ]

A dry cannon uses TNT to launch TNT (or even the user on creative style). Dry cannons are uncomplicated, easy to build and effective but crave lots of obsidian or other blast-resistant materials.

The main departure between a dry 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 block tin be any blazon of cake (except obsidian, bedrock and whatever other blast-resistant blocks) and provides a buffer betwixt the accuse and the shot. Sand, snow, wool and other soft blocks seem to produce the best effects.
The shot is a block of TNT or the user if you are on creative fashion and drop into position on fourth dimension.

Vertical cannon [ ]

This design is a vertical cannon simply tin be turned horizontally besides.

The cannon is built entirely of obsidian.

Showtime past building a 5x5x4 rectangular prism, leaving a 3x3x2 chamber within.
Make a pigsty in the top middle of the prism.
Place one piece of obsidian on the center cake at the bottom of the chamber. This is the mounting block.
Load bottom layer of bedchamber with TNT. This is the charge.
Identify the wadding on acme of the mounting block.
Place the shot on the wadding.
Provide a redstone circuit so all the charge blocks are activated simultaneously.
Stand dorsum and throw the switch!

Horizontal cannon [ ]

Make a long tube of obsidian (works best with 3x3x6 or 3x3x7) with a hollow middle. Then, put 2 blocks of obsidian on the height. Hollow it out. Fill with TNT, and put an non-blast resistant cake in the last space on the front. Encompass the top with redstone, and place a push on the back. Optionally, make a platform to stand up on when you trigger information technology. You should also go far a little ways off the footing. See diagram below, in which the orange stands for the wadding (shown in cutaway side view):

It will launch several blocks of TNT at your target, yet it is expensive and does non have a very long range, merely with a big cannon, y'all can shred a large corporeality of land with each shot. Occasionally the redstone will be blasted off if y'all have a large cannon, so it is good to continue some redstone on hand. Good for the defense of a village (blast mobs with a row of cannons when they come also shut!). All-time for creative mode due to the large amount of TNT needed for each shot.

TNT catapults [ ]

Slime blocks, introduced in one.8, can bounce entities to sure 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 burn in an arc.
They utilize much less TNT than other cannons of their skill.
They can be fired extremely rapidly.

Cons

It can be difficult to obtain the pistons and slime blocks needed.
The catapult has a fixed target and express range.

TNT lifter [ ]

A TNT cannon might shoot TNTs far away, just not high up. this design uses an ordinary cannon, but uses slime blocks to launch it higher.

Video examples [ ]

Mortar - High angle shot using a ladder mounting block.
Compact - The shot is primed by mitt, which must now be done with flint and steel
Super large cannon - Firing other entities.

Trivia [ ]

TNT cannon firing is the most random consequence in Minecraft, because of thousands of different sample points taken to make up one's mind dozens (or fifty-fifty hundreds) of different vectors which are and then added together to form the base trajectory of a shot. Nonetheless, it is possible to make some cannons, peculiarly vertical mortars, 99% accurate (the accuse falls back into the barrel and detonates at a specific acme).
If y'all're actually lazy and have operator privileges (or in singleplayer with cheats), you lot can just use commands or control blocks instead. The command /summon minecraft:tnt ~ ~2 ~ {Fuse:12,Motion:[one.0,0.0,0.0]} volition fling a lit TNT eastward, starting from merely in a higher place your head.
TNT cannons tend to burn down further when facing east or south.
