I want to create a watchtower that does not provide vision of itself when captured, but rather a completely random unrelated part on the other side of the map. Also, can a map still be a melee map with such a radical change to a watchtower?
This is untested pseudo-code, so it probably won't work right-off-the-bat - (I used to use the BW map editor)
