Hello, I'm new to map making.
Have been reading through the tutorials provided.
I have a few questions.

How do I make it so that its possible for all players in force 1 to be able to build from 1 barrack or gateway.. Etc.

And how to make it so as to only when its main player is near the building then only can he build unit or upgrade from that particular building.

Thanks.
David

You only need to post this once, and the UMS Assistance is the correct forum, this forum is for ideas and new concepts.

do current player bring (unit to location) give unit to currnet player then
current player bring 0 unit give unit building to who ever owned it first

Bad description really for a new guy but it works in a nut shell...

This does answer your question, but since you are clearly new to mapmaking, here are the basics. Just play the map. It is from Falkoner's 'Test Compilation'.
