Description

Script interface for Particle Systems.

A powerful and versatile Particle System component.

General parameters

The Particle System's general parameters are kept inside a special Main module. These parameters are visible in the Inspector above all the other modules:



In script, these parameters are accessible through ParticleSystem.main.

Module effect multipliers

Every module has special multiplier properties that allow you to change the overall effect of a curve without having to edit the curve itself. These multiplier properties are all named after the curve they affect - for instance ParticleSystem.emission.rateMultiplier controls the overall effect of ParticleSystem.emission.rate in a given system.

Constant value shorthand

Parameters support a shorthand notation for simple constant values. To set a constant value for a parameter, all you need to do is assign a number to it. It is not necessary to create a MinMaxCurve or MinMaxGradient object in the ParticleSystemCurveMode.Constant mode.

For example, instead of:
ParticleSystem.emission.rate = new ParticleSystem.MinMaxCurve(5.0f);
write:
ParticleSystem.emission.rate = 5.0f;

Performance note: When setting properties on particle modules, the settings are passed immediately into native code. This gives the best performance. This means that setting properties on a module struct doesn't set something in script that requires setting back to the Particle System; it all happens automatically.

Variables

collisionScript interface for the Particle System collision module.
colorBySpeedScript interface for the Particle System color by lifetime module.

inheritVelocityScript interface for the Particle System velocity inheritance module.
isEmittingDetermines whether the Particle System is emitting particles. A Particle System may stop emitting when its emission module has finished, it has been paused or if the system has been stopped using Stop with the StopEmitting flag. Resume emitting by calling Play.
isPausedDetermines whether the Particle System is paused.
isPlayingDetermines whether the Particle System is playing.
isStoppedDetermines whether the Particle System is stopped.
