설명

The duration of the Particle System in seconds.

You can only set this property when the Particle System is not playing.

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(); } }
