See.. My problem here is that there is a dropship, lets say, with 4 heavy units and one is a zealot
Will this satisfy the condition,
player X brings X units to location M?
Or can you do
Remove all zealots for current player at dropship?? will these work?
Well, if you'd test it yourself, you can find out. Took me about 30 seconds to test myself.
Yes, all of those will work.
Note though, that zealots in a dropship COUNT AS AIR UNITS. (Double click on a location, see those little check boxes? unchecking the all three ELEVATION boxes, will make the location work ONLY FOR AIR UNITS at that location)
So with all three "elevation" boxes unchecked, and you do a trigger like:
Brings at least 1 zealot at location
Remove 2 zealot at location
And the player brings 2 zealots to location, one in dropship, one walking on ground.
Then only the one in the air (dropship) will be removed. The one on ground will remain.
Hope this helps!
