Vuforia学习之播放音频文件

1. 创建Audio Source

   
   
   

   Audio Source

2. Audio Source添加音频文件

   
   
   

   AudioClip

3. 取消Image Target的Defaule Trackable Event Handler（script）选中

   
   
   

   Defaule Trackable Event Handler（script）

4. 创建C#Script

   
   
   

   C#Script

5. 编辑代码

using UnityEngine;
using System.Collections;  
using Vuforia; 
public class Music_Lhy : MonoBehaviour,ITrackableEventHandler {  
    #region PRIVATE_MEMBER_VARIABLES  
    public GameObject UI;  
    private TrackableBehaviour mTrackableBehaviour;  

    #endregion // PRIVATE_MEMBER_VARIABLES  

    #region UNTIY_MONOBEHAVIOUR_METHODS  

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

    #endregion // UNTIY_MONOBEHAVIOUR_METHODS  
    #region PUBLIC_METHODS  
    public void OnTrackableStateChanged(  
        TrackableBehaviour.Status previousStatus,  
        TrackableBehaviour.Status newStatus)  
    {  
        if (newStatus == TrackableBehaviour.Status.DETECTED ||  
            newStatus == TrackableBehaviour.Status.TRACKED ||  
            newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)  
        {  
            OnTrackingFound();  
            UI.SetActive (true);  
        }  
        else  
        {  
            UI.SetActive (false);  
            OnTrackingLost();  
        }  
    }  

    #endregion // PUBLIC_METHODS  

    #region PRIVATE_METHODS  

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

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

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

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

        Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " lost");  
    }  

    #endregion // PRIVATE_METHODS  
}  

6. 把脚本拖给Image Target并选择UI文件

   
   
   

   选择UI

7. 补充说明
   这里可以设置Audio Source的一些属性
