I want to cause a series of events to happen when I activate a lever. I want a few reference to enable, sounds to play, etc. This is no problem.

But I also want to create a big fire explosion in the end of the script, but I don't know how to do that.

You can play an explosion easily in script I have a water explosion when you poison a giant slaughterfish (so cool I know )

Can't remember the code now but ill post it later if noone else does it's simple.
