ParticleSystem.collision

描述

粒子系统碰撞模块的脚本接口。

The collision module enables particles to collide with a predefined list of planes, or with the 2D and 3D physics worlds.

不需要将粒子系统模块重新分配回系统；它们是接口而不是独立的对象。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var coll = ps.collision;
        coll.enabled = true;
        coll.bounce = 0.5f;
    }
}
