Explosion

Cause an explosion for rockets, grenades, and more!

WeaponMechanics has a custom explosion system (We don't use the same code for TNT as most plugins do). This allows us to control every explosion aspect, like the shape and damage.

If you are using WorldGuard, you can disable explosions in regions. Check out Addons #WorldGuard for more information.

Knockback_Multiplier

Controls how much knockback entities get from the explosion. Defaults to 1.0. Set to 0.0 to disable knockback. Using numbers >1 will throw players faster and further.

Explosion_Exposure

An entity's exposure determines how much damage they take. Exposure is challenging to calculate and involves ray tracing. To minimize potential lag, you may want to change this setting.

DEFAULT

Explosion_Exposure: DEFAULT

This method is just like vanilla, but it uses the most CPU. Great for weapons that have a long reload time or otherwise aren't used often.

OPTIMIZED

DISTANCE

NONE

Explosion_Shape

The shape of the blocks that are blown up. Each shape uses it's own "arguments" in Explosion_Type_Data. Check each shape for a simple example.

DEFAULT

Replicates a vanilla explosion. Arguments:

• Yield -> The maximum distance from the center that blocks are broken.

  • For reference, tnt=4, creeper=3, charged creeper=6

• Rays -> The number of ray casts for each direction. Defaults to 16.

  • Increasing the number of rays may look better, but it costs more CPU.

The following example creates a large explosion with increased detail.

  Explosion:
    # Other args...
    Explosion_Shape: DEFAULT
    Explosion_Type_Data:
      Yield: 15.0
      Rays: 32

The DEFAULT explosion shape cannot destroy blocks that vanilla explosions can break. For example, obsidian and bedrock cannot be broken. If you want to damage these blocks, use another shape, like SPHERE.

SPHERE

CUBE

PARABOLA

Detonation

Determines when the explosion triggers. For a Molotov, you probably want it to explode on impact. But for a frag, you probably want it to explode a fixed time after you throw it.

• Delay_After_Impact

  • The delay, in ticks, between the "impact" and the explosion.

• Remove_Projectile_On_Detonation

  • Use true to remove the projectile after the explosion.

• Impact_When

  • Spawn -> Triggers after spawning. Good for frags.

  • Entity -> Triggers after hitting an entity.

  • Block -> Triggers after hitting a block.

The following example will cause the explosion 5 seconds (100 ticks) after shooting the projectile.

  Explosion:
    # Other args...
    Detonation:
      Delay_After_Impact: 100
      Remove_Projectile_On_Detonation: true
      Impact_When:
        Spawn: true

Cluster_Bomb

Cluster bombs use recursion, which means that explosions spawn projectiles, which spawn explosions (and so on).

• Split_Projectile

  • Uses the Projectile serializer.

  • Defaults to the projectile used for the gun.

• Projectile_Speed

  • The speed, in $\frac{m}{s}$, that the projectile should spawn with.

  • Defaults to 30.

• Number_Of_Bombs

  • The number of projectiles to spawn for each explosion.

• Number_Of_Splits

  • The number of iterations.

  • For most use cases, this number should be 1.

• Detonation

  • Same as #Detonation, but now used for new projectiles.

• Mechanics

  • The mechanics to trigger whenever a split occurs (good for playing a sound to warn players of the split).

  • See the Mechanics wiki.

  • @Source{} -> The shooter of the weapon

  • @Target{} -> The split location (not an entity).

Airstrike

Drops projectiles from the sky, good for flare guns.

• Dropped_Projectile

  • Uses the Projectile serializer.

  • Defaults to the projectile used for the gun.

• Minimum_Bombs

  • The minimum number of bombs to drop

• Maximum_Bombs

  • The maximum number of bombs to drop.

• Height

  • How high up to drop the bombs from

  • Defaults to 60 blocks

• Vertical_Randomness

  • Adds some randomness, so bombs explode at different times.

  • Defaults to 5.0 (airstrike location can vary by 10 blocks).

• Distance_Between_Bombs

  • The minimum distance between dropped bombs.

  • Defaults to 3.0 blocks.

• Maximum_Distance_From_Center

  • Defines how far away (horizontally) the bombs can drop.

  • Defaults to 25.0 block radius.

• Layers

  • Repeats the airstrike.

  • Defaults to 1.

• Delay_Between_Layers

  • The delay, in ticks, between repetitions.

  • Defaults to 40 ticks

• Detonation

  • Same as #Detonation, but used for the dropped bombs.

• Mechanics

  • The mechanics to trigger whenever an airstrike spawns. Great for playing a "bombs away" sound.

  • Use the Mechanics wiki.

  • @Source{} -> The shooter of the airstrike.

  • @Target{} -> The location of the projectile (not an entity).

Block_Damage

Check out our Block Damage wiki for information!

Regeneration

Used together with the Block_Damage feature. This regenerates blocks over time.

Regeneration isn't perfect. Anything that causes block updates (players breaking blocks, redstone loops, pistons, some entities, etc.) can cause regeneration issues.

Hopper-reliant systems, like item sorters, are almost guaranteed to break during regeneration. Protect your regions using Addons #WorldGuard.

• Ticks_Before_Start

  • The time, in ticks, before the first blocks begin to regenerate.

• Max_Blocks_Per_Update

  • How many blocks to regenerate for each update.

• Ticks_Between_Updates

  • The time, in ticks, between regenerations.

Flashbang

Let's you execute mechanics on people who are looking at the explosion.

• Effect_Distance

  • The maximum distance away an entity should be to be safe.

• Mechanics

  • The mechanics to trigger on each victim.

  • Use the Mechanics wiki.

  • @Source{} the shooter of the weapon.

  • @Target{} the victim who was flash banged.

The following example will blind all players affected by the flashbang:

  Explosion:
    # Other args...
    Flashbang:
      Effect_Distance: 10.0
      Mechanics:
        - "Potion{potion=BLINDNESS} @Target{}"

Mechanics

Mechanics to trigger when the explosion occurs. Used to play an explosion sound usually.

• @Source{} -> The shooter of the weapon.

• @Target{} -> The location of the explosion (not an entity).

Explosion Example

This explosion breaks a few specific blocks (see below) in a 5.5-block radius. Blocks begin to regenerate after 2 minutes.

Bedrock, obsidian, and netherite cannot be damaged. Any material with "glass" in its name is broken in 2 shots, except for any material with "glass_pane" in the name, which can be broken in 1 shot. Any material with "wood" in the name can be broken in 6 shots, and dirt can be broken in 4 shots. All other materials cannot be broken, but they appear to take 12 shots of damage and show the crack animation. 10 seconds after a block is broken, it is regenerated.

  Explosion:
    Explosion_Exposure: DEFAULT
    Explosion_Shape: SPHERE
    Explosion_Type_Data:
      Radius: 5.5
    Block_Damage: 
      Spawn_Falling_Block_Chance: 20% 
      Default_Block_Durability: 12
      Default_Mode: CRACK
      Blocks:
        - bedrock CANCEL
        - obsidian CANCEL
        - netherite_block CANCEL
        - $glass BREAK 2
        - $glass_pane BREAK 1
        - $wood BREAK 6
        - dirt BREAK 4
    Regeneration:
      Ticks_Before_Start: 2400 
      Max_Blocks_Per_Update: 4
      Ticks_Between_Updates: 5

Notice how $glass_pane is below $glass$. This is because order matters. When using the wildcard character $, make sure to use the "more general blocks" (Like any glass block) before the "more specific blocks" (Like any glass pane).
