Particle System Control

Particle System Control manages particle playback, emission rates, and simulation — essential for VFX triggers, environmental effects, and dynamic particle systems.

Overview​

Purpose: Control particle system playback and properties

Common Use Cases:

  • Particle Playback: Start/stop particle emission
  • Emission Control: Dynamic emission rate changes
  • Particle Looping: Continuous particle effects
  • Simulation Control: Particle simulation management

Animation Types​

Playback Animations​

  • Play Particles — Start particle emission
  • Stop Particles — Stop particle emission
  • Loop Particles — Continuous particle loop

Property Animations​

  • Emission Rate Tween — Emission rate transition

Simulation Animations​

  • Simulate Particles — Particle simulation control

Common Parameters​

  • Duration: 0.1–5.0s typical (start/stop: instant, emission tween: 1.0–5.0s)
  • Easing: EaseInOutQuad for smooth emission changes, Linear for rate control
  • Loop Type: None (one-time), Loop for continuous particles

Best Practices​

  • Use particle playback for VFX triggers
  • Use emission rate tweens for dynamic particle intensity
  • Use loop particles for ambient effects
  • Optimize particle counts for mobile devices
