{{About|explosion mechanics|raiding and defense strategies|Raiding}}
'''Cannoning''' is a method of [[Bases_and_Raiding|raiding]] a faction whereby an initiator (i.e., the attacker) breaches a defending faction's base by launching TNTs at their walls. Cannoning exploits a property that water-protected walls can be breached by causing a TNT to explode inside a block (particularly, sand) than inside water (which would cancel the explosion).

CosmicPE has the most advanced redstone mechanics on Bedrock Edition, therefore, what works on other faction servers may not necessarily function 1:1 on CosmicPE. CosmicPE hosts a free [minecraft:?addExternalServer=CosmicPE|cannon.cosmicpe.me:19132 Cannon Planet] creative-mode server with TNT and redstone enabled, whereby players can collaborate and build full-fledged cannons on their 40×40 chunk plots before rebuilding the same on the main factions planet.

{{Warning|Redstone mechanics on CosmicPE are coded from scratch, meaning they are neither at par with Minecraft: Bedrock Edition nor Minecraft: Java Edition. However, Java 1.8.8 is used as a reference to test logic of the mechanics.}}

== Block Behaviour ==
In cannoning mechanics, obsidian and enchantment tables are considered specialty blocks because they have a different durability mechanism. Blast resistance of both blocks is lowered, meaning obsidian is not immune to explosions. Obsidian has 4 durability points (DP), while enchantment tables have 6 DP. Explosions reduce DP by 1 and a block breaks when it loses all DP. These specialty blocks can be queried for their DP by right-clicking them using a potato. There is a 5-minute accruement period from the time a durable block is placed, prior to which the block has effectively 0 DP.

Fence gates, brewing stands, carpets, daylight sensors, spawners, and player heads blow up even when water protected. Water will not flow into lava (hence not form stone or obsidian as a result). Water and lava can both be sponged. Water flows instantaneously along Y axis.

== TNT ==
TNTs can be lobbed over Y255, however they will not explode nor deal durability damage if the explosion occurs at any point above Y255. There is a TNT limit of 500 on the server, including any custom TNT spawned by custom enchantments and world events (e.g., [[Bosses|bosses]]). TNT is not affected by water currents. An explosion that occurs underwater will not damage blocks, but will supply knockback to surrounding entities. Besides normal (vanilla) TNT, there are 8 other types of custom TNTs on the server relevant to cannoning.
* '''Gigantic TNT''': Explodes in a much larger radius. Spawns 2 extra explosions at <math>y+3</math> and <math>y-3</math> of TNT, and another 3 explosions at either <math>x+3</math>, <math>z+3</math> or <math>x-3</math> and <math>z-3</math>.
* '''Lethal TNT''': A more dense explosion. Creates 4x extra TNT explosions at the same location of the original. This effectively destroys 4/4 obsidian in one explosion.
* '''Lucky TNT''': Increases chances of a [[Monster_Spawner|spawner]] dropping from the explosion by 2x.
* '''Tactical TNT''': Explosion only affects [[Monster_Spawner|spawner]]s. No other blocks are affected.
* '''Mimic TNT''': Repeats an explosion many times. Spawns a TNT explosion at the same location every 5 seconds for the total of 15 seconds (i.e., 3 explosions).
* '''Hex TNT''': Weakens block durability of any durability blocks it damages. Durability blocks take 2x damage for 30 seconds since this explosion.
* '''Silent TNT''': Quiet, makes much less noise. Explosion can only be heard by players with 16x16 blocks (horizontally).
* '''Anti-Gravity TNT''': Explosion only affects blocks with gravity (e.g., sand), and do not cause any physical events.

== Creeper Egg ==
A creeper egg is a portable source of explosion. Unlike TNT, a creeper egg can be placed even in enemy territory. This makes it possible to collect [[Monster_Spawner|spawners]] and other blocks in enemy land, which otherwise cannot be mined using tools. Like custom TNTs, custom creepers exist. A lucky creeper is the most effective method to collect spawners from enemy land. Creeper eggs cannot break obsidian blocks.

Creepers are neutral, meaning they will not explode soon as they are spawned or are in the vicinity of a player. Instead, they explode upon being attacked. A creeper has an explosion radius of 4, however this can be increased to 6 by using the <code>/smite</code> command to charge the creeper. Creepers have a lower mass than vanilla, meaning they are less influenced by gravity and will appear to float (to some extent) when in air. A creeper may be killed before it explodes, causing it to drop as a creeper egg.

== Limitations ==
Regarding Piston and Redstone Interactions, when a piston is pulsing ''(turning on and off)'' near redstone repeaters that are also pulsing, the repeaters closest to the piston will experience a slight increase in their game tick speed. This causes the pulse of those repeaters to accelerate slightly. This shift can affect the timing of a cannon, so it may be necessary to adjust the positioning of repeaters away from nearby pistons to avoid inconsistencies.

• '''Slime Blocks''' do not function as expected in CosmicPE and cannot be used as usually intended.

• '''Redstone Comparators''' only detect a basic amount of items in a container. The redstone power works as follows,

• '''Zero items''': powers 1 redstone dust. 
• '''42 items''': powers 2 redstone dust. 
• '''41 items''': powers 3 redstone dust. 

After this point, every additional '''41 items''' will increase the redstone power by one dust. A full dispenser will provide enough items for a comparator to reach 15 redstone dust. '''Comparators''' also function similarly to repeaters but '''lack the additional features that comparators typically offer''' in other versions of Minecraft.

For '''sand mechanics''', sand falls naturally from '''Y1 to Y16''', however '''above Y16''', the sand will '''instantly fall''' all the way down to improve server performance. This can impact a sand comp for a cannon and overall limitations when building a cannon.

== Tips & Tricks ==
Refilling dispensers with TNTs while cannoning is often tedious. Players can use the <code>/fill</code> command to auto-fill dispensers in their vicinity. Sand gen buckets can be purchased from <code>/shop</code> to help with sand-stacking. If you built a cannon on cannon planet, there is a way to [https://www.youtube.com/watch?v=cBuEZwYimPI&ab_channel=SPTimelapse| export it as a a schematic] and then use it for reference on the main faction server, though this is not managed by CosmicPE.

== Booster Module ==
[[File:BoosterModule.jpeg|thumb|400px|Booster Module Preview with height marked via purple and white concrete.]]
The '''Booster Module''' is essential to compress a cannon’s power, allowing for more efficient shooting and stronger explosions. It’s crucial for the cannon’s functionality and its distance coverage.

'''<big>Build-it-Yourself</big> '''
Begin by aligning your dispensers to dispense on a centered block ''(as shown in the image)'', there will be '''3 pillars''' of dispensers that are each '''7 dispensers high''' with '''4 blocks below''' to create the platform of the cannon. Place the remaining '''16 blocks''' as shown where there is a '''2-block separation''' above and below the platforms.

'''Blocks Required '''
• 21 Dispensers 
• 20 Blocks


== Power Module ==
[[File:PowerModule.png|thumb|400px|Power module with blue terracotta placed and purple and white concrete to mark the length of the platform.]]
The '''Power Module''' is responsible for the total distance a cannon can fire. The more power you dispense, the farther your cannon will reach.

'''<big>Build-it-Yourself</big> '''
Follow the example given with blue terracotta to show block placement. Start by extending from the power module '''7 blocks forward''' with the first block being the wall to separate both modules and the next '''6 blocks''' to be a blueprint for the '''6 pillars''' of dispensers on both sides. Afterwards, build the '''supporting platforms''' for the dispenser to rest on, following the example provided.
 
 
 
[[File:PowerModuleFull.png|400px|thumb|left|Completed Power Module with dispensers.]]
 
Finally, complete this module by placing in the '''84 dispensers''' accordingly. It’s important to consider at this point the cannon should be symmetrical on both sides if not, then something is missing.
 
 
'''Blocks Required '''
• 96 Blocks 
• 84 Dispensers

 
 
 
== Nuker Module ==
[[File:NukerModule.png|thumb|400px|Nuker Module first of 3 parts built with ladders and cobwebs.]]

The '''Nuker Module''' is the heart of a cannon. Which is responsible for the explosions that go through the base itself.

'''<big>Build-it-Yourself</big> '''
Start by placing a '''6-block floor''' as indicated by the red blocks. The first pillar should be '''7-blocks high''' on each side to separate the Nuker from the Power Module. Add ladders in the center of the pillars and place '''cobwebs''' in the next '''5 blocks''', where the TNT will land.

On both sides of the cobwebs, place blocks going '''2 blocks up''' on each side to contain the TNT. This section is where the symmetry of the cannon ends, as the actual dispensing of the Nuker will differ. The pattern should be: '''dispenser, sticky piston, 1 block space''', repeat this pattern to make '''3 rows''' of dispensers and sticky pistons.

[[File:NukerModulePart.png|400px|thumb|left|Nuker Module second of 3 parts built with sticky pistons and redstone blocks.]]
 
 
 
Next, rotate to the opposite side and place '''sticky pistons''' with '''redstone blocks''' facing downward. Ensure the '''redstone blocks activate the sticky pistons''' ''(not the dispensers)''. Use the image provided as a model.
 
 
 
 
 

[[File:NukerModuleFull.png|thumb|400px|Nuker Module, completed with blocks to serve as redstone wiring platforms using 17 additional blocks.]]

 
 

'''Blocks Required '''
• 47 Blocks 
• 15 Dispensers 
• 15 Redstone Blocks 
• 15 Sticky Pistons 
• 7 Ladders 

 
 

== Redstone Wiring ==
[[File:WiringBackView.png|thumb|400px|Booster Module Preview with height marked via purple and white concrete.]]
Wiring of a cannon brings the entire construction to life. Bringing the integration needed for the individual modules to work as one.

'''<big>Build-it-Yourself</big> '''
Redstone is all about symmetry and repetition. Whatever you do on one side of the cannon, repeat it on the other. For the '''Booster''' and '''Power Modules''', wire the redstone symmetrically, with '''no changes to the repeater timings'''. Make sure to include '''2 blocks''' that will serve as redstone connection between the lower and upper half with a '''button''' to activate the cannon.
 
 
 
 

[[File:WiringSideView.png|400px|thumb|left|Right side view showcasing wiring to connect the Nuker module to the cannon.]]
 
 
 
For the '''Nuker''', start by placing '''1 piece of redstone''' to connect the Power Module. Then, place '''2 repeaters at max ticks'''. Fill in the remaining spaces with '''2 redstone torches''', followed by redstone and additional repeaters. Pay close attention to the timing, incorrect timing may cause the cannon to misfire and possibly blow up.
 
 
 
 
[[File:WiringBirdsEye.png|thumb|400px|Birds eye view of the Nuker showing wiring with redstone ticks.]]
 
 
 
'''Blocks Required '''
• 46 Redstone Dust 
• 46 Redstone Repeaters 
• 2 Redstone Torches 
• 2 Blocks 
• 1 Button 

 
 
== Watering ==
Water provides protection against the explosions that’ll occur from the booster & power as the cannon is firing.
[[File:WateredCannon.jpeg|400px|thumb|left]]
 
'''<big>Build-it-Yourself</big> '''
Place '''1 water bucket''' in the highlighted white box at the floor of the Booster Module. This will provide water protection for the Power Module up to the ladders separating the Nuker from the Power.

'''Blocks Required '''
• 1 Water Bucket
