Hello Mapster, I'm a member of the map making team TPW (Icetoad, on this site my account is GoldGod). I am thinking of using eggs that worked like in BW, but the problem is that worker can not cut throw it. I am able to make eggs that can be destroy, but this is only a part of what I want. Being a melee map maker makes me kinda bad at data and trigger.
-Make neutral zerg egg to act like in BW. So worker can pass throw it, but not other unit.
-No use of Trigger, so only data and nothing that can change unit status in term of gameplay.
-No use of Campaign dependencies
This would help me a lot and I thank you already in advance if any of you could make it work for me.
I think it would require using one of the currently unused unit collision types, changing every not-burrowed not-a-worker mobile ground unit in the game to collide with that type, and setting the egg to use only that collision type. However, in SC1, workers failed to collide with any ground units, but only while attempting to gather resources. You could accomplish that by giving the workers a behavior, with a validator that makes sure it is using the Gather ability at any stage, with the Suppress Collision flag set.
If you want to see, how it could be done and how it works: Take a look at the 'toss Force Field and Zeratul. Most ground units do have the Movement-Collide-Flag Force Field set. Zeratul does not have this flag! He can walk through a Force Field ;)
