Stopping at wall

is there a possible way that you can make a unit NOT try to find another way around a wall?
i.e.: unit is issued to move to an area past a wall, so it tries to move around.
i need it so it stops right there

Make like a big region through the wall,
and if a unit enters issue order to stop.

Or Better Yet Use Path Blockers

Hope that helps :D

If you use Pathing blockers, the unit will still try to move around. The onyl solution would be to place regions at suitable locations with the order stop.

ah, yeah, i knew i would have to use regions, it's not neccessary for me to do this though, thx for the responses anyway
