Im workin on a mod, and im tryin to get creep colonys to spawn larva, so far no luck, anything would be appreciated, Thank you in advance.
Check out it's Idle orders in the AI/Orders tab in DatEdit. Make them the same as those of a Hatchery/Lair/Hive and see what happens.
Larva spawning seems to be hardcoded to the three Hatcheries.
If you are doing MemGraft work you could take one of those and put it in the creepcolony's space with creepcolony's graphics.
Woot unit substitution. Or try changing the order requirements for "Spawning Larva" so that Creep Colonies are included. That might do it.
