Class ParticleDescriptionProvider

java.lang.Object

net.neoforged.neoforge.client.data.ParticleDescriptionProvider

All Implemented Interfaces:

net.minecraft.data.DataProvider

Direct Known Subclasses:

DataGeneratorTest.ParticleDescriptions

public abstract class ParticleDescriptionProvider
extends Object
implements net.minecraft.data.DataProvider

A data provider for ParticleDescriptions.

To use this provider, extend this class and implement addDescriptions(). Then, register an instance using DataGenerator.addProvider(boolean, Factory) via the GatherDataEvent on the mod event bus.

A description can be added to a ParticleType which uses a sprite or sprite set.

 @Override
 protected void addDescriptions() {
     // Single sprite
     this.sprite(ParticleTypes.DRIPPING_LAVA, ResourceLocation.withDefaultNamespace("drip_hang"));

     // Multiple sprites
     this.spriteSet(ParticleTypes.CLOUD, ResourceLocation.withDefaultNamespace("generic"), 8, true);
 }
 

A particle description holds a list of textures used when rendering the particle to the screen. All registered particle descriptions are stitched together into a texture atlas called TextureAtlas.LOCATION_PARTICLES. A ParticleType whose particle uses the texture atlas, typically via the ParticleRenderType, can then reference the necessary texture during rendering.

Particles with a particle description must have their particle providers attached to a ParticleType as a sprite or sprite set consumer.

Constructor Details

ParticleDescriptionProvider

protected ParticleDescriptionProvider(net.minecraft.data.PackOutput output)

Creates an instance of the data provider.

Parameters:

output - the expected root directory the data generator outputs to

Method Details

addDescriptions

protected abstract void addDescriptions()

Registers the particle descriptions generated by sprite(ParticleType, ResourceLocation) or one of the sprite set methods.

sprite

protected void sprite(net.minecraft.core.particles.ParticleType<?> type,
 net.minecraft.resources.ResourceLocation texture)

Creates a new particle description that contains a single texture for the associated ParticleType.

Particle types with this description should be attached to a particle provider via RegisterParticleProvidersEvent.registerSprite(ParticleType, ParticleProvider.Sprite).

Parameters:

type - the particle type the textures are applied for

texture - the texture to render for the particle type

Throws:

NullPointerException - if the particle type is not registered

IllegalArgumentException - if a texture does not have an associated PNG file, or the particle type has already been provided

spriteSet

protected void spriteSet(net.minecraft.core.particles.ParticleType<?> type,
 net.minecraft.resources.ResourceLocation baseName,
 int numOfTextures,
 boolean reverse)

Creates a new particle description that contains multiple textures for the associated ParticleType. The textures are generated from a common name and appended with a number representing the state of the animation.

 minecraft:generic_0
 minecraft:generic_1
 minecraft:generic_2
 // ...
 

Particle types with this description should be attached to a particle provider via RegisterParticleProvidersEvent.registerSpriteSet(ParticleType, ParticleEngine.SpriteParticleRegistration).

Parameters:

type - the particle type the textures are applied for

baseName - the common name of all the textures

numOfTextures - the number of textures within the set

reverse - when true, the textures will be listed in descending order

Throws:

NullPointerException - if the particle type is not registered

IllegalArgumentException - if a texture does not have an associated PNG file, or the particle type has already been provided

spriteSet

protected void spriteSet(net.minecraft.core.particles.ParticleType<?> type,
 net.minecraft.resources.ResourceLocation texture,
 net.minecraft.resources.ResourceLocation... textures)

Creates a new particle description that contains multiple textures for the associated ParticleType. The textures are passed as varargs with at least one texture present.

Particle types with this description should be attached to a particle provider via RegisterParticleProvidersEvent.registerSpriteSet(ParticleType, ParticleEngine.SpriteParticleRegistration).

Parameters:

type - the particle type the textures are applied for

texture - the first texture in the description

textures - a list of subsequent textures to render for the particle type

Throws:

NullPointerException - if the particle type is not registered

IllegalArgumentException - if a texture does not have an associated PNG file, or the particle type has already been provided

spriteSet

protected void spriteSet(net.minecraft.core.particles.ParticleType<?> type,
 Iterable<net.minecraft.resources.ResourceLocation> textures)

Creates a new particle description that contains multiple textures for the associated ParticleType. The textures are passed as an iterable.

Particle types with this description should be attached to a particle provider via RegisterParticleProvidersEvent.registerSpriteSet(ParticleType, ParticleEngine.SpriteParticleRegistration).

Parameters:

type - the particle type the textures are applied for

textures - a list of textures to render for the particle type

Throws:

NullPointerException - if the particle type is not registered

IllegalArgumentException - if there are no textures provided, a texture does not have an associated PNG file, or the particle type has already been provided
