Question Two sounds does not work ?

I'm using unity 19.3.13f1 version. In my script there are two sounds (emptyObject with audioSource attached) play when get near J object. But it does not work !! Like a bug maybe. Here is my script

Code (CSharp):

1.  
2.     public AudioSource a, b;
3.     public GameObject j;
4.     public float distance;
5.  
6.     // Update is called once per frame
7.     void Update()
8.     {
9.         distance = Vector3.Distance(gameObject.transform.position, j.transform.position);
10.         if (distance <= 5)
11.         {
12.             a.GetComponent<AudioSource>().Play();
13.             b.GetComponent<AudioSource>().Play();
14.  
15.         }
16.         else
17.         {
18.             a.GetComponent<AudioSource>().Stop();
19.             b.GetComponent<AudioSource>().Stop();
20.         }
21.     }

Did anyone notes it ?

 

Since this is in Update(), you're restarting the audio clip every frame by calling Play() every frame.

 

Ok. what to do when "A" sound is play once, and "B" sound is a loop. How to solve this ?
