I need to make Creep not spread anywhere on the entire map, but in such a way that I can still spawn buildings with Create Unit. Anyone know a way?

I can't just fill the whole map with Terran/Protoss buildings. I tried, but it brought the map to map max before I got to anywhere near filling the whole map.

If I can't get this to work, then I don't think I can do my map. Which would suck for me.

use square terrain to section off the area you want contained.

Constantly create and remove the building.

@Echo: That won't work, I need Sunken (and possibly Spore) Colonies to be able to attack and be attacked and Creep Colonies/Hives to be attackable.

@razorsnail: That also won't work, I need to be able to move buildings in one-square increments. The main reason I'm posting this is because I'm trying to avoid creep getting screwed up when I move the buildings. (I have an alternative building system in mind which lets the player build off Creep, so it's not needed.)

Make some extractors on the unwanted creep, then kill them.

This should work, this has been found to work

You could constantly create pylons around it, and remove them.

I ran into this problem on the Jungle terrain. I just copied and pasted a small custom doodad under the sunken. You can't see it when the sunkens there, but when it's dead, you see this triangle thing blended in pretty well.

The problem with this is that the player in my map will be able to create Colonies, so I can't make it rely on the terrain to work.

Make the creep removal optional. If the player wants to, he or she can bring an overlord on top of the creep colony, and when the conditions are met, a location is centered over the overlord/creep colony, a bunch of extractors are made (via mobile grid of course) and killed. in the area for a normal creep colony. That way, the creep colony can be an extra defense/offensive tactic which would prevent hostile buildings from being placed.

Interesting. But what happens when a unit is in the mobile grid:

ERROR - WTF?XTRACTOR UNPLACEABLE.

Mark unit placement in area and move, mobile grid and move back.
