[jonnyknows 0]

how do i make a building that makes other buildings invisable. this is a very dumb question becuase its probly very hard to do but i want it to make your units and other buildings invisble in a certain range nd reveal those buildings when you go near them. if its possible how can i do it?

isn't it that it can be less than 16, but it must be greater than 1? i forgot... i haven't been here in a while
