Making units block Line of sight without triggers

Is this possible? I want to have my gate building block line of sight without triggering line of sight blockers.

have you tried using doadads? ive never tried them myself cause i havent had the time, but do they work?

I cant use doodads, the gate has to belong to a player.

i really don't think there is. if there was a way tho there may be a spot for allowing the line of site in the object editor somewhere near the pathing map. but i doubt it. as far as i can see i would advice you trigger in some line of sight blockers. it seems like you are having a hard time with that gate tho man.
