Unity 和 vuforia 脚本错误

Question

我在这个脚本中遇到了这个问题。

使用UnityEngine； 使用 Vuforia；

公共类 TouchInput_1 : MonoBehaviour, ITrackableEventHandler { 私有 TrackableBehaviour mTrackableBehaviour； 公共游戏对象 temploMaiaObject； // 引用名为“Templo_Maia”的 3D 对象 私人音频源音频源； private bool isPlaying = false;

void Start()
{
    audioSource = temploMaiaObject.GetComponent<AudioSource>();

    // Register this script to trackable event handler
    mTrackableBehaviour = GetComponent<TrackableBehaviour>();
    if (mTrackableBehaviour)
    {
        mTrackableBehaviour.RegisterTrackableEventHandler(this);
    }
}

void OnDestroy()
{
    // Unregister this script from trackable event handler
    if (mTrackableBehaviour)
    {
        mTrackableBehaviour.UnregisterTrackableEventHandler(this);
    }
}

public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus)
{
    if (newStatus == TrackableBehaviour.Status.DETECTED ||
        newStatus == TrackableBehaviour.Status.TRACKED ||
        newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
    {
        // Target is detected and being tracked
        Debug.Log("Target is detected!");

        // Enable touch input
        enabled = true;
    }
    else
    {
        // Target is lost or not being tracked
        Debug.Log("Target is lost!");

        // Disable touch input
        enabled = false;

        // Pause audio playback
        if (isPlaying)
        {

我希望链接到图像目标的 3D 元素能够通过触摸屏控制播放和暂停链接到它的音频源。
