how can i make an exploder explode?
i've spawned it, and without any key which by default is nothing my Radiant says, but it doesn;t do anything. i have everything set up but the actual explosion, how can i make an exploder explode?

With this line.

exec global/exploder.scr::explode 1 // 1 being the #set number of the exploder.
