Class ParticlePool

Namespace

PopcorningGuineaPig.Engine.Rendering

Assembly

PopcorningGuineaPig.Engine.dll

Fixed CPU billboard pool. Technique from Banqi CaptureVfx and Sven ParticlePool. No per-particle heap, no Box3D, no PGPSCN nodes.

Methods

Clear()

public void Clear()

CreateHardTexture(int)

Hard disc with ~1.5 px AA rim — for blood droplets / gib chunks that must not read as smoke (soft radial). White RGB so tint carries the color.

public static Texture2D CreateHardTexture(int size = 64)

Parameters

size int

Returns

Texture2D

CreateSoftTexture()

Runtime 64² radial falloff. Games with their own sprites skip this.

public static Texture2D CreateSoftTexture()

Returns

Texture2D

Draw(Camera3D)

public void Draw(Camera3D camera)

Parameters

camera Camera3D

Emit(in Particle)

One fully-specified mote. Games use this for their own recipes.

public void Emit(in Particle particle)

Parameters

particle Particle

Emit(int, Vector3, in ParticleConfig)

Burst. Each mote samples config independently.

public void Emit(int count, Vector3 at, in ParticleConfig config)

Parameters

count int

at Vector3

config ParticleConfig

EmitPerSecond(ref float, float, float, Vector3, in ParticleConfig)

Rate emitter. Caller owns accumulator so many emitters can share one pool without the pool allocating a list of rates.

public void EmitPerSecond(ref float accumulator, float dt, float perSecond, Vector3 at, in ParticleConfig config)

Parameters

accumulator float

dt float

perSecond float

at Vector3

config ParticleConfig

RemoveTagged(byte)

Drop every mote whose Tag equals tag.

public void RemoveTagged(byte tag)

Parameters

tag byte

Update(float)

public void Update(float dt)

Parameters

dt float
