First, sorry bad English <img src="smileys/smiley9.gif" border="0" align="middle" />.
I am developing a game with 35 levels. In 10 of these levels there are some saws. I would like to put a distinctive sound these saws, but do not know how. I set the sound using the command "IS ON SCREEN", but the sound appears at all levels, including those which have not. How do I set a sound to a specific sprite, in this case, to the saws?
