Scroll bar help

[Adeel]

Hi guys,

I'm just after a bit of help with making a music scroll bar with ngui I have a 16 minute audio track and I am using a scroll bar to try and move it to the right point in the audio. I have it working in that it moves along with the audio however every time I move the scroll bar it always restarts the track from the beginning.
Heres the stuff I have so far:

1. public UIScrollBar scrollBar;
2.  
3.         public AudioSource mainMusic;
4.  
5.         public float newMusicTime;
6.  
7.         void Update()
8.         {
9.                 if(AudioControllers.musicPlaying == true && AudioControllers.pauseMusic == false)
10.                 {
11.                         scrollBar.value += 1 / mainMusic.clip.length * Time.deltaTime;
12.  
13.                         if(Input.GetMouseButtonUp(0))
14.                         {
15.                                 mainMusic.time = scrollBar.value;
16.  
17.                         }
18.                 }
19.         }

I feel that I am close but its just not working any help would be much appreciated.

Thanks.

If i'm not mistaken, the Scroll Bar's value only has a range from 0 to 1, so you're constantly setting the time on the audio source to something like the first 0-1 seconds.

If my above statement is right, then it should be something like this:

1. public UIScrollBar scrollBar;
2.  
3.     public AudioSource mainMusic;
4.  
5.     public float newMusicTime;
6.  
7.     void Update()
8.     {
9.         if(AudioControllers.musicPlaying == true && AudioControllers.pauseMusic == false)
10.         {
11.             scrollBar.value += 1 / mainMusic.clip.length * Time.deltaTime;
12.  
13.             if(Input.GetMouseButtonUp(0))
14.             {
15.                 // so for example your scrollbar is at the half -> its .value is 0.5f
16.                 // then you'd set the time to 0.5 * CLIPLENGTH
17.                 mainMusic.time = scrollBar.value * mainMusic.clip.length;
18.             }
19.         }
20.     }
21.

Yes that's right, scroll bar's value is always 0 to 1.

Thanks for the reply and sorry for the lateness of mine I've not had  a good Internet connection for the last couple of days!

Yeah the scroll bar value is 0-1 your suggestions looks about right I'll give it a go and reply when I've tested it on Thursday. Thanks again.
