ok heres what i have, i have a trigger around a gate. Whenever a East unit goes into the trigger area the gate opens, when the unit leaves the trigger area the gate closes. But i would like to place some units around the gate (guards basically), the problem is that if i place them around the gate they are in the trigger area and they trigger the trigger. How can i get the trigger to ignore the units i have placed to guard the gate but let every other east unit through
