Cant seem to find it..

Thanks in advance--

go to triggers, creat a trigger, click new event, choose unit enters region.

No.. I'm looking for a way to tell if a unit enters ANY region on the map.

well you could do if unit enters playable map area but if you dont want that you will have to manually do enters region for every single region
