This is probably a newb-ish question, but I've been trying to give the Command Center/Orbital Command/Planetary Fortress the ability to attach a Reactor and Tech Lab.

I've duplicated the Factory's Reactor, its normal/death/splat actors, its reactor morph and Factory - AddOns ability, its behavior and its "Reactor Not Factory" validator. Changed all instances of Factory with Command Center and of the Factory's Reactor with the (custom) CC's Reactor.

However, it says "Can't build. Location invalid." every time I try to build it ingame. Am I doing something wrong, or have to do anything else?

Is it trying to build the add-on in the command center?

Nope, it gives me that invalid location error message and doesn't build it at all.

Look under Behavior - Add On Offset X and Behavior - Add On Offset Y. It's possible the values are too small and the addon is trying to build inside the cc which is the problem.

Made a new footprint for the Command Center w/ Addon, and gave it to the Reactor for Pathing Placement. When I try to build a reactor, it shows me the placement model, but says invalid location when I try to place it (The footprint shape is the same as the CC's, 7x5 in size, and with 4 squares on the bottom right for the addon).

Also, didn't find any behaviors named "Add On Offset"...It works if I set the CC's pathing to 3x3 and reactor's to 3x3 + 2x2, though.

Oh, that worked, thanks for the help!
