Mike|||Ok, I will look at these documents.|||Well, I have some questions yet.
1. I tried to give the weapons of the Aeon tech 1 fighter the ability to fight air and ground targets, but now they only fight ground targets.
How can I give the same weapon different located targets?
2. And there is also the question, how I can give the Fatboy the ability to build all airunits of the UEF.
EDIT
1. I have found the problem. I lost Air in the FireTargetLayerCapsTable.|||AIhelper|||Thank you. :)
