I have been ask by a spanish user this

when i kill all the enmies on my level how do i get the music to stop.

I think what he is looking for is how to script a kill countdown. when the countdown goes to 0 the music stops.

can any one help.

Thanks ardentcrest, I am this user who has made the question.
the problem is solved, i use triggers , commands SetEVentState and GetEventState, and i'm a script running in background wich check the triggers. This script stops musics, play musics, open doors, close doors, etc.
