Script interface for particle systems (Shuriken).

Shuriken is 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);
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.
