如何检查音频是否已完成播放并在音频播放完毕后调用OnTrackingFound（）？

Question

当播放音频时，系统应该忽略其他所有内容，直到音频结束，但是当音频结束并且音频完成时你有一个目标，它需要调用OnTrackingFound（）函数。 如果我等待音频完成然后向相机显示目标，它工作正常（它调用OnTrackingFound），但是当我在播放音频时显示目标时它将忽略目标（这是可以的），但是当音频完成并且目标存在而不等待音频完成时，它不应该忽略它。

public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus,TrackableBehaviour.Status newStatus)
            {    

                    if (newStatus == TrackableBehaviour.Status.DETECTED ||
                        newStatus == TrackableBehaviour.Status.TRACKED ||
                        newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED) {
                    if (notCorrect.isPlaying || correct.isPlaying || FindTheCard.isPlaying || Quiz.currentPoint.GetComponent<AudioSource>().isPlaying || tryagain.isPlaying || GameObject.Find ("LetsTryNumbers").GetComponent<AudioSource> ().isPlaying ||  GameObject.Find ("LetsTryLetters").GetComponent<AudioSource> ().isPlaying || GameObject.Find ("LetsTryAnother").GetComponent<AudioSource> ().isPlaying  || GameObject.Find ("Correct").GetComponent<AudioSource> ().isPlaying ||  GameObject.Find ("CorrectAnimals").GetComponent<AudioSource> ().isPlaying || GameObject.Find ("CorrectLetters").GetComponent<AudioSource> ().isPlaying || GameObject.Find ("LetsTryAnotherModel").GetComponent<AudioSource> ().isPlaying)
                    {
                        OnTrackingLost();

                    }
                    else 
                    {

                            OnTrackingFound (); 
                    }

                    }
            }

Answer 1

public AudioSource audio;
public event Action<bool> OnPlayDone = ()=>{};
IEnumerator PlayAndWaitForAudio()
{
    // Set all things off
    OnPlayDone(false);
    this.audio.Play(); // Considering the clip is loaded already
    while(this.audio.isPlaying == true){
        yield return null;
    }
    // Set all things on
    OnPlayDone(true);
}

应该对等待作出反应的任何组件都会注册该事件。然后你可以相应地设置：

void Start(){
    GetComponent<AudioController>().OnPlayDone += HandlerAudio;
}
private bool isAudioDone = false;
private void HandlerAudio(bool value){
    this.isAudioDone = value;
}
public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus,TrackableBehaviour.Status newStatus)
{
     if(this.isAudioDone == false){ return; }
     // Rest of the method
}
