Vision Through Gates

[opi]

Im making a closed dungeon style map like warchasers, but theres a problem with the gates. Players and creeps can both see through any of the doors I place. This means that players can see whats on the other side of teh door without breaking it, and creeps will stack up on teh door or shoot through it at players. Is there any way to make it impossible to see through the doors without hundreds of vision triggers or pathing blockers (wehich i tried, but they persist even after the door is destroyed)

There is a think called Line of Sight Blocker, which is the same thing as Path Blocker but just for sight so you can go over the LoS blocker if you want.

Do a trigger like when gate is destroy remove LoS blocker.
