I would like to create a trigger which detects particular Units beeing in a Region covering a specific Cliff level. I'm used to Starcraft Broodwar system, where you just check a Flag in the Region properties so it will only affect a the selected Clifflevel. However, I just can't manage to find a solution for this in SC2. Well... I could create the regions out of 1000 shapes, so only a specific clifflevel is covered, but I'm sure there is a much better way... I mean you can even paint textures etc. based on Cliff level. There must be an more efficient way of doing this.
