I have got two ideas. What if instead of building a bunker make the computer to build a supply on its base (which is much easier) and then to move building supply to the place where the bunker should be and when the supply is finished create a bunker on its place. And the second idea is to create SCV and to run an AI script Harvest Town on the location which makes the computer build a Command Center there. And when the CC is finished to replace it with bunker.
Well, I tried to make a test map and faied with both. The problem with the first idea is that you CANNOT
move the unfinished terrain building...
And if you could you should somehow tell the computer to finish it at its new place, if the construction cancels during the movement (mabe scrip Harvest Town could help, dont know). The second idea works fine when you make one CC but then AI scripts shuffle and the computer dont want to build CC at the exatclty that place where you told him to do it.
If there was a way to cancel those AI scripts (such as clear combat data for orders)...
But I find out another interesting thing
(maby you guys already know about it) that when giving the building which is under the construction the construction would not cancel and the computer will finish it for another player.
Here is my experamental map... Have you got any Ideas how to get around this...
