Audio file is not playing

December 23, 2013 - 6:47am #1
 I need to play sound & 3d object to be render while target tracking. I mada a .cs script file and added below code, then drag this script to ImageTarget. And imported the .mp3 file to asset folder. But it's not working.
 
code:
 
using UnityEngine;
using System.Collections;
 
public class sound : MonoBehaviour {
 
// Use this for initialization
void Start () {
 
GameObject go = GameObject.Find("bird");
go.animation.Play("Marudhaani");
 
}
 
// Update is called once per frame
void Update () {
 
}
}

I tried with below code. It's working. 

 

public AudioClip clip;

Public AudioSource source;

TrackingFound:

source.transform.position=transform.position;

source.PlayOneShot(clip);

 

TrackingLost:

source.Stop();

I have written up a small tutorial for playing and stopping audio clips in response to image target detection / loss events:

https://developer.vuforia.com/forum/faq/unity-how-can-i-play-audio-when-targets-get-detected

Hope this helps.

If i point the camera to target the audio playing, then i move the camera the target lost. So, i don't need to play. Is it unity or vuforia? I'm confusing. Because target isn't based on vuforia?

Seriously ... this is outside the scope of these forums.

If you do not know how to use the Unity debugger then please refer to the Unity documentation at their web site.

 Why it's not losing?

You need to use the debugger, as really only you can answer your question.  You also need to look at the other thread wher you posted the identical code as I tried to answer there.

In general, you will have more luck in the forums if you carry out some of your own investigations this way and then highlight specific technical areas where we may be able to assist.  Simply saying "it is not working" provides little information for us to help.

Hope you can understand.

 

thanks

Can you please avoid double posting the same code and questions in multiple threads.

This causes confusion and delays.

This question seems to be about pure Unity programming, not Vuforia.

What about looking here :

http://unity3d.com/

?
