Projectile

Customize how the projectile flies and interacts

This section defines how your projectile moves and interacts with the environment. Remember that your projectiles are not actual entities. Instead, WeaponMechanics uses math and ray-tracing to simulate the position/movement of the projectile.

Projectile: <path to another Projectile>

Usually, you define projectiles in the projectiles folder, that way you can re-use the projectile in multiple weapons. For example, in this config, my_weapon and my_other_weapon both use my_projectile for their projectile. This saves you time, so you don't have to type things over.

# This goes in the weapons folder
my_weapon:
  Projectile: "my_projectile.Projectile"
  Shoot: <shoot configurations>
  Reload: <reload configurations>
  <etc.>

my_other_weapon:
  Projectile: "my_projectile.Projectile"
  Shoot: <shoot configurations>
  Reload: <reload configurations>
  <etc.>

# This goes in the projectiles folders
my_projectile:
  Projectile:
    Projectile_Settings: ...
    Sticky: ...
    <etc.>

Type

Which entity does the projectile look like? It can look like an arrow, a snowball, a fireball, an end dragon, or any kind of entity type you want. Projectiles can also be hidden by using "invisible" for this option (This helps save some CPU performance). Use an #entity for the projectile (or "invisible").

Projectile_Item_Or_Block

Some entities can use an item for extra data. A DROPPED_ITEM requires it to determine which item to drop. FALLING_BLOCK requires it to determine which block to use. ARMOR_STAND will add any item here on it's head. The armor stand is very useful for showing custom ammo models, like a rocket for an RPG.

Use the Item Serializer for all options.

Since this uses the Item Serializer, you can use the Custom_Model_Data in your projectiles, like this:

my_projectile:
  Projectile:
    Projectile_Settings:
      Type: DROPPED_ITEM
      Projectile_Item_Or_Block:
        Type: IRON_NUGGET
        Custom_Model_Data: 10 

Gravity

This defines vertical acceleration. Positive numbers make the projectile fall down over time, and negative numbers make the projectile float up over time. The numbers are in blocks/second^2. Vanilla Minecraft uses 10 here. Earth's gravity is about 9.8, and the Moon's gravity is about 1.62. Using 0 will make the projectile "float" in a straight line.

Minimum

• Speed

  • The minimum speed the projectile can travel at.

• Remove_Projectile

  • Whether to remove the projectile when the minimum speed is reached.

  • true = The projectile will be removed when the minimum speed is reached.

Maximum

• Speed:

  • The maximum speed the projectile can travel at.

• Remove_Projectile:

  • Whether to remove the projectile when the maximum speed is reached.

Drag

Drag allows you to multiply projectile velocity by a number every tick. Since we want the projectile to slow down, we should use a number between 0.0 and 1.0 (But you probably want to keep this between 0.9 and 1.0, otherwise the projectile may slow down too quickly). Using exactly 1.0 will keep speed constant, and using any number above 1.0 will increase speed over time.

• Base

  • The amount to multiply the speed by every tick.

• In_Water

  • The amount to multiply the speed by when the projectile is in liquid.

• When_Raining_Or_Snowing

  • The amount to multiply the speed by when it is raining or snowing.

You cannot use negative numbers for drag. To slow the projectile down, use a positive number <1, like 0.98. To speed the projectile up like a rocket, use a positive number >1, like 1.03.

Disable_Entity_Collisions

Setting this to true will stop the projectile from colliding with entities. This is useful for providing a CPU performance boost to your projectile, but it will disable all entity interacts.

Using this feature disables all entity interactions, including Sticky, Bouncy, Through, and direct damage. This feature should probably only be used for grenades, since they do not need to hit entities.

Maximum_Alive_Ticks

Defines the maximum amount of time, in ticks, in which projectile can be alive. Defaults to 600 which is equal to 30 seconds.

Maximum_Travel_Distance

Defines the maximum amount of distance this projectile can travel before being removed.

Size

Defines the size of projectile that is used for hit detection. This size is added to each direction. Meaning 0.5 is same as 1x1x1 in size. Important note about using this is that, this only works for entities and NOT for blocks. Defaults to 0.1. As an example arrow and snowball have this set to 0.3 in vanilla.

Sticky

Use the Sticky wiki page.

Bouncy

Use the Bouncy wiki page.

Through

Use the Through wiki page.

Mechanics:

Casts mechanics to projectile's location. Useful when you want to make beeping for a grenade. Use Mechanics.
