Kodo Tag Maze

[Djey-]

I've been making a Kodo Tag map with a friend.

I hope everyone here know what it is.. if not..
You are a Guy that tries to escape from Kodos which follows you where ever you are. There is some bases where you can build a base and protect yourself.
You can
1. Bunker yourself if it is a version when the Kodos attacks the closest object or unit instead of following the hero where ever he is.
2. Maze. You build a Maze around the base that the Kodo will walk to get you.
If there is a open path towards the hero. (you) the kodo won't attack the buildings.. if it however is. he will destroy the walls.

I want the 2 one because it's funnier. The only thing is that I don't know how to do it. I mean you can't block with Immortal walls. then the Kodos won't get to you at all. Help is appreciated

Try making the Kodo unable to attack structures (only ground units and mechanical). You can classify the attackable buildings as ground instead of structure.
