Hi guys, i have created this script it basically plays a song when clicked on and that's all good but i would like to ask your help with something. what i want to do is if i click on my GUI button while the song is playing i want it to stop the track. This is if i click on the same GUI if the music is playing.

Here is the script :

  var MyAudioTrack1Naruto : AudioClip;
     //var MyAudioTrack2Naruto : AudioClip;
       //var MyAudioTrack3Naruto : AudioClip;
         //var MyAudioTrack4Naruto : AudioClip;
           //var MyAudioTrack5Naruto : AudioClip;

     function OnGUI () { 

       //Make the first button

        if(GUI.Button (Rect(10, 20,105,20),  "Play Track 1 (Naruto Enter) ")){
           if (!audio.isPlaying){
                audio.Stop(); //if something else is playing stop it and then play track 
                 audio.clip = MyAudioTrack1Naruto;
                     audio.PlayOneShot(MyAudioTrack1Naruto);    

                           }
                               }
                                   }

Oh and thanks in advance :)
