ParticleSystem.colorOverLifetime

Description

Script interface for the Particle System color over lifetime module.

This module changes the colors assigned to particles over time, based on how long each particle has been alive.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

public class ExampleClass : MonoBehaviour {
    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var col = ps.colorOverLifetime;
        col.enabled = true;

        Gradient grad = new Gradient();
        grad.SetKeys( new GradientColorKey[] { new GradientColorKey(Color.blue, 0.0f), new GradientColorKey(Color.red, 1.0f) }, new GradientAlphaKey[] { new GradientAlphaKey(1.0f, 0.0f), new GradientAlphaKey(0.0f, 1.0f) } );

        col.color = grad;
    }
