particleDestinationGeneratorSearch playground for particleDestinationGenerator

particleDestinationGenerator: ((index: number, particle: Nullable<Particle>, outDestination: Vector3) => void)

Type declaration

    • Gets or sets the destination generator that will create the final destination of each particle.

      • Index will be provided when used with GPU particle. Particle will be provided when used with CPU particles

      Parameters

      Returns void

particlePositionGeneratorSearch playground for particlePositionGenerator

particlePositionGenerator: ((index: number, particle: Nullable<Particle>, outPosition: Vector3) => void)

Type declaration

    • Gets or sets the position generator that will create the initial position of each particle. Index will be provided when used with GPU particle. Particle will be provided when used with CPU particles

      Parameters

      Returns void
