粒子系统的持续时间(以秒为单位)。
仅当粒子系统未播放时才能设置此属性。
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { private ParticleSystem ps;
void Start() { ps = GetComponent<ParticleSystem>(); ps.Stop(); // Cannot set duration whilst particle system is playing
var main = ps.main; main.duration = 10.0f;
ps.Play(); } }
