ParticleEmitterComponent.Timing.repeating(warmUp:emit:idle:)

Emits for the given emit duration, and waits idle seconds before looping, warmUp determines how long the simulation should appear to have run before first appearing.

case repeating(warmUp: TimeInterval? = nil, emit: ParticleEmitterComponent.Timing.VariableDuration, idle: ParticleEmitterComponent.Timing.VariableDuration? = nil)
