I am new to the world builder and I have been editing maps lately, but I want to know how to make it so that I can make units and buildings on my side (example: I want to put towers in my base so I have defense right from the start of the game, but when I put like a Missile tower up, it just stays on no team and I can't capture it or anything) Is there any way to set buildings and units to my side so I don't have to go around and capture them all?
I would like a simple way and not a script, but if it has to be a script, then that is ok.

If none of what I just said made sense, then here: I just want to be able to give myself buildings and units so I don't have to capture them.
Is there a way to do this?

Unfortunately, scripting will be your only choice here.
Please go through section 2 and section 4 of this tutorial

Ok thanks so much I will take a look at it.
