播放音频并播放更多内容

Question

我正在用C#进行团结的小游戏.

到目前为止,我已设法设计级别并完成一些基本脚本.

目前我有一个触发器,它产生一个对象,并希望它一旦用户进入就播放和音频源.但是,因为我希望它是一个跳跃恐慌,触发器非常小,目前声音只播放IF我留在触发器.

我的代码如下:

using UnityEngine;
using System.Collections;

public class Spawner : MonoBehaviour {

    public GameObject monster;
    public AudioSource aud; 
    public AudioClip piano; 

    void Start () 
    {
        monster.SetActive (false);
        aud = monster.GetComponent<AudioSource>();
    }

    void OnTriggerEnter(Collider other){
        if (other.CompareTag ("Player")) {
            monster.SetActive (true);
            AudioSource.PlayClipAtPoint(piano, monster.transform.position);
        }

    }

    void OnTriggerExit(Collider other){
        if (other.CompareTag ("Player")) {
            monster.SetActive (false);
        }
        Destroy (this.gameObject);
    }

}

我想知道是否有一种方法可以在人们离开扳机后保持声音播放.

谢谢!

附加的GameObject音频在音频播放完毕之前被销毁.使用AudioSource.PlayClipAtPoint将创建和销毁Audiosource使得缓存aud无用.此外,如果你有太多的触发游戏对象,那将会很慢因为GC.使用Coroutine并等待音频完成播放然后销毁gameObject.

public GameObject monster;
public AudioSource aud;
public AudioClip piano;

void Start()
{
    monster.SetActive(false);
    aud = GetComponent<AudioSource>();
}

void OnTriggerEnter(Collider other)
{
    if (aud.isPlaying)
    {
        return; //Exit if Audio is already playing
    }

    if (other.CompareTag("Player"))
    {
        monster.SetActive(true);
        aud.PlayOneShot(piano);
    }

}

void OnTriggerExit(Collider other)
{
    if (other.CompareTag("Player"))
    {
        monster.SetActive(false);
    }
    StartCoroutine(waitForAudioThenDestroy());
}

IEnumerator waitForAudioThenDestroy()
{
    //Wait until we are done playing
    while (aud.isPlaying)
    {
        yield return null;//Don't freeze
    }

    //We are no longer playing audio so we can destroy this gameObject now
    Destroy(this.gameObject);
}
