# Particles Control Action

With the event system, you can control when an emitter should be emitting or not. To do so, you can use the Particle Control Action that can be triggered by most events.

**Emitter** - Select Particle Emitter to control.

**Emission (Start, Stop, Start/Stop, Pause, Pause/Resume, or Reset)** - Decide how to control the emission of the particles.

**Delay** - Time before the event action is triggered.
