Particle emitter emitting particles from the inside of a box. It emits the particles randomly between 2 given directions.

Constructors

  • Creates a new instance BoxParticleEmitter

    Returns BoxParticleEmitter

Properties

direction1: Vector3

Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.

direction2: Vector3

Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.

maxEmitBox: Vector3

Maximum box point around our emitter. Our emitter is the center of particles source, but if you want your particles to emit from more than one point, then you can tell it to do so.

minEmitBox: Vector3

Minimum box point around our emitter. Our emitter is the center of particles source, but if you want your particles to emit from more than one point, then you can tell it to do so.

Methods

  • applyToShader(uboOrEffect: UniformBufferEffectCommonAccessor): void
  • Called by the GPUParticleSystem to setup the update shader

    Parameters

    • uboOrEffect: UniformBufferEffectCommonAccessor

      defines the update shader

    Returns void

  • getClassName(): string
  • Returns the string "BoxParticleEmitter"

    Returns string

    a string containing the class name

  • getEffectDefines(): string
  • Returns a string to use to update the GPU particles update shader

    Returns string

    a string containing the defines string

  • parse(serializationObject: any): void
  • Parse properties from a JSON object

    Parameters

    • serializationObject: any

      defines the JSON object

    Returns void

  • serialize(): any
  • Serializes the particle system to a JSON object.

    Returns any

    the JSON object

  • startDirectionFunction(worldMatrix: Matrix, directionToUpdate: Vector3, particle: Particle, isLocal: boolean): void
  • Called by the particle System when the direction is computed for the created particle.

    Parameters

    • worldMatrix: Matrix

      is the world matrix of the particle system

    • directionToUpdate: Vector3

      is the direction vector to update with the result

    • particle: Particle

      is the particle we are computed the direction for

    • isLocal: boolean

      defines if the direction should be set in local space

    Returns void

  • startPositionFunction(worldMatrix: Matrix, positionToUpdate: Vector3, particle: Particle, isLocal: boolean): void
  • Called by the particle System when the position is computed for the created particle.

    Parameters

    • worldMatrix: Matrix

      is the world matrix of the particle system

    • positionToUpdate: Vector3

      is the position vector to update with the result

    • particle: Particle

      is the particle we are computed the position for

    • isLocal: boolean

      defines if the position should be set in local space

    Returns void
