（Unity3d）Vuforia开发基础六-音频

在学会利用U3d处理音频之后，看下面的教程。  
1、 虚拟按钮  
结合Vuforia 虚拟按钮制作教程，在该方法下添加对应事件。  

复制代码

/// <summary>
    /// Called when the virtual button has just been pressed:
    /// </summary>
    public void OnButtonPressed(VirtualButtonAbstractBehaviour vb)
    {
        if (!button_audio.isPlaying) {
            button_audio.Play();        
        }
        if (button_audio.isPlaying) {
            button_audio.volume=1;      
        }
        Debug.Log("OnButtonPressed::" + vb.VirtualButtonName);

        // Add the material corresponding to this virtual button
        // to the active material list:
        switch (vb.VirtualButtonName)
        {
        case "one":
            //myObject.transform.animation.Play();
            myObject.transform.animation.Play("Take 4");
            labelname = "one -> Run！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            if (button_audio.isPlaying) {
                button_audio.volume=1;      
            }
            break;

        case "two":
            myObject.transform.animation.Play("Take 002");
            labelname = "two -> Nothing！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        case "three":
            //myObject.transform.animation.Play("Take 4");
            myObject.transform.animation.Play();
            labelname = "three -> Stand！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        case "four":
            myObject.transform.animation.Play("Take 5");
            labelname = "four -> Hello！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        }
    }

2、 模型出现  
 
在 DefaultTrackableEventHandler 脚本中， OnTrackingFoun d方法触发。  

复制代码

private void OnTrackingFound()
        {
            if (!baymax_audio.isPlaying) {
                baymax_audio.Play ();
            }
            if (baymax_audio.isPlaying) {
                baymax_audio.volume = 60;           
            }

            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");
        }

3、按钮事件  
 

总结：  
1、 和Unity3D播放音频处理方式一样  
  if  (!button_audio.isPlaying) {  
  button_audio.Play();  
  }  
2、对AR场景中，音效触发事件的不同 在学会利用U3d处理音频之后，看下面的教程。

        if (!button_audio.isPlaying) {
            button_audio.Play();        
        }
        if (button_audio.isPlaying) {
            button_audio.volume=1;      
        }
        Debug.Log("OnButtonPressed::" + vb.VirtualButtonName);

        // Add the material corresponding to this virtual button
        // to the active material list:
        switch (vb.VirtualButtonName)
        {
        case "one":
            //myObject.transform.animation.Play();
            myObject.transform.animation.Play("Take 4");
            labelname = "one -> Run！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            if (button_audio.isPlaying) {
                button_audio.volume=1;      
            }
            break;

        case "two":
            myObject.transform.animation.Play("Take 002");
            labelname = "two -> Nothing！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        case "three":
            //myObject.transform.animation.Play("Take 4");
            myObject.transform.animation.Play();
            labelname = "three -> Stand！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        case "four":
            myObject.transform.animation.Play("Take 5");
            labelname = "four -> Hello！";
            if (!button_audio.isPlaying) {
                button_audio.Play();        
            }
            break;

        }
    }

            }
            if (baymax_audio.isPlaying) {
                baymax_audio.volume = 60;           
            }

            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");
