Multiple bomb spawns, one explosion sound.

So I made my character spawn bombs and explode 1 second later. but then thing is when i spawn multiple bombs, Only 1 explosion sound happens, the rest of the bombs don't have a sound.

Do you want it like this?

Start the game and let the first bomb go, all the bombs on the screen blow up, one after the other.

Yeah, you could say that. Seems like the thing I want to happen. Do you know how?

Yup, that's my game :).

This is the code I used.

So I have to make the bombs into a group?
