| class | ParticleGraphEmitter |
Instance of particle graph layer in emitter.

Reset the particle emitter layer completely. Removes current particles, sets emitting state on, and resets the emission timer.
|
private |
Temp memory needed for graph calculation. TODO: Should be replaced with memory pool as it could be shared between multiple emitter instances.
