当我检测到目标时，我在#unity 中检测到多个图像目标我播放了一个发音图像目标名称的声音。如果我检测到一个目标，它会大声播放声音，但是当检测到多个目标时，它会大声播放其中一个声音，而将其他目标播放得非常低或不播放。请我想在教程中执行此操作的具体方法或在您的答案中解释。

使用 UnityEngine；

public class SoundPlay: MonoBehaviour,ITrackableEventHandler
{
#region PRIVATE_MEMBER_VARIABLES

private TrackableBehaviour mTrackableBehaviour;
public AudioClip sound;
#endregion // PRIVATE_MEMBER_VARIABLES



#region UNTIY_MONOBEHAVIOUR_METHODS

void Start()
{
    mTrackableBehaviour = GetComponent<TrackableBehaviour>();
    if (mTrackableBehaviour)
    {
        mTrackableBehaviour.RegisterTrackableEventHandler(this);
    }
}

#endregion // UNTIY_MONOBEHAVIOUR_METHODS



#region PUBLIC_METHODS

/// <summary>
/// Implementation of the ITrackableEventHandler function called when the
/// tracking state changes.
/// </summary>
public void OnTrackableStateChanged(
                                TrackableBehaviour.Status previousStatus,
                                TrackableBehaviour.Status newStatus)
{
    if (newStatus == TrackableBehaviour.Status.DETECTED ||
        newStatus == TrackableBehaviour.Status.TRACKED)
    {
        OnTrackingFound();
    }
    else
    {
        OnTrackingLost();
    }
}

#endregion // PUBLIC_METHODS



#region PRIVATE_METHODS


private void OnTrackingFound()
{
    Renderer[] rendererComponents = GetComponentsInChildren<Renderer>(true);
    Collider[] colliderComponents = GetComponentsInChildren<Collider>(true);

    // Enable rendering:
    foreach (Renderer component in rendererComponents)
    {
        component.enabled = true;
    }

    // Enable colliders:
    foreach (Collider component in colliderComponents)
    {
        component.enabled = true;
    }

    Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " found");
    GetComponentInChildren<fiveSound>().Play();
}


private void OnTrackingLost()
{
    Renderer[] rendererComponents = GetComponentsInChildren<Renderer>(true);
    Collider[] colliderComponents = GetComponentsInChildren<Collider>(true);

    // Disable rendering:

是否检查了 3D 声音？

如果是则取消选中。让我知道你是怎么办的！
