Pausing a game using colliders

How can I paused my game including the music that is playing when two objects collide. I tried setting Time.timeScale to 0 in the OnTriggerEnter function but it is not working. My game is still running. Can anyone please tell me how to do it? Thanks a bunch! Sorry I am such a newbie.

Edited:

I just read this from another post:

" Time.timeScale doesn't affect movements like transform.Translate(0,40,0) as they don't really on the time scale."

I'm afraid my application has movements stated above. Does anyone knows how can I paused and quit my application then? Thanks a lot.
