in world builder? i dont have a clue, ive been trying to work it out, i can get a building to 'spawn' but the building seems to just be dead, and wouldnt do anything, you can try making a dozer use the command bar button you want at the position you want, it might work, dont know, it didnt work when i wanted the building to build infantry
when i tried to make it spawn, it just appears, then sites there, and wouldnt do nothing, i spawned a defence gun, and it just sat there, and got destroyed...
I guess you'll need the Build List Tool to do that... but I think you can't tell the AI they shall build a structure at a waypoint. With the Build List you do it by coordinates. Id unno if it works... I've no experience with the build list.
The BuildList is what the AI uses now, but what I'm trying to do is have the AI build a structure at a certain waypoint, regardless of its position. So if that waypoint is right up against a cliff the AI will build a structure there.
