播放并等待音频播放完毕

Question

在我的项目中，我想要播放声音，然后将对象的活动状态设置为 false，目前两者同时发生，因此声音不会播放。如果我将活动状态保持为 true，那么我会听到声音播放。

如何确保音频在设置的活动状态切换为 false 之前完成，如有任何帮助或建议，我们将不胜感激。

这是我的代码的选择；

 void OnTriggerEnter(Collider other)
 {
     if (other.tag == "Pick Up") 
     {
         if (!isPlayed) {
             source.Play ();
             isPlayed = true;
         }
     }
     if (other.gameObject.CompareTag ("Pick Up"))
     {
         other.gameObject.SetActive (true);
         count = count + 1;
         SetCountText ();
     }
 }

按照 Joe 的说法使用协程。每次启用碰撞对象时启动协程。

void OnTriggerEnter(Collider other)
 {
     if (other.tag == "Pick Up") 
     {
         if (!isPlayed) {
             source.Play ();
             isPlayed = true;
         }
     }
     if (other.gameObject.CompareTag ("Pick Up"))
     {
         other.gameObject.SetActive (true);
         count = count + 1;
         SetCountText ();
         StartCoroutine(waitForSound(other)); //Start Coroutine
     }
 }



 IEnumerator waitForSound(Collider other)
    {
        //Wait Until Sound has finished playing
        while (source.isPlaying)
        {
            yield return null;
        }

       //Auidio has finished playing, disable GameObject
        other.gameObject.SetActive(false);
    }

您可以使用其

renderer

隐藏对象，以及关闭所有碰撞器，播放声音，然后销毁/将其设置为非活动状态：

renderer.enabled = false;
gameObject.collider.enabled = false;

audio.PlayOneShot(someAudioClip);
Destroy(gameObject, someAudioClip.length); //wait until the audio has finished playing before destroying the gameobject
// Or set it to inactive

许多帖子指出使用 WaitForSeconds 以及 WaitWhile(AudioSource.isPlaying) 的问题，如果剪辑暂停、游戏失去焦点或音频音调发生改变，则会给出错误的值。

所以我相信我找到了更好的解决方案：

void OnTriggerEnter(Collider other)
{
    if (other.tag == "Pick Up") 
    {
        if (!isPlayed) 
        {
            source.Play ();
            isPlayed = true;
        }
    }
    if (other.gameObject.CompareTag ("Pick Up"))
    {
        other.gameObject.SetActive (true);
        count = count + 1;
        SetCountText ();
        StartCoroutine(waitForSound(other)); //Start Coroutine
    }
}

private IEnumerator PlayAudioAndDeactivate(Collider other)
{
    audioSource.clip = clip;
    audioSource.Play();
    yield return new WaitUntil(() => audioSource.time >= clip.length);
    other.gameObject.SetActive(false); //Whatever it is that you're wanting to do.
}

通过使用 AudioSource.time 和 AudioClip.length，您可以将播放位置与剪辑的长度进行比较，这应该始终是正确的。我已经通过暂停和音调变化成功地测试了这一点。
