Spawn problem.
 

(I have looked for a few hours for an answer to this but I could not find an answer.)

The Backround: I am attempting to create a multiplayer map for JKA. I am trying to make it very big, and I need swoops to get around.

The Problem: I have the swoops and the building containing them all set to go. However, I want them to respawn when I press a button which will conveniently be next to or attached to the building. So the question is; how do I do it? I have GTKradiant 1.4.0 (1.5.0 is incompatible).
