Would it be possible to create an infinite loop?
Say, in an online game, you want an area to be occupied by only one person at a time. Person enters area, automatically destroys trigger crate, thus locking himself in that area. Same person exits area by destroying another crate, leaving the area empty. Can the cycle continue? As in, another person comes, destroys first crate, locks himself etc. or same person comes and does the same thing again.

I'm really interested as this could help IMMENSELY with my level and with many interesting concepts, for that matter.
