ParticleSystem.colorOverLifetime

설명

Script interface for the ColorOverLifetimeModule of a Particle System.

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.

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
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;
    }
