[Unsolved] Constructing buildings on other buildings

[Userkaffe I]

Hi

I'm working on a RTS-map. I'd like to make each races main building only placeable on certain spots on the map. (Expansion locations)

I think the best way to do this would be to make it so that main buildings could only be placed on dummy buildings that are preplaced on map. (Similar to how refinery requires a vespene geyser) Same functionality can also be found in Age of Mythology.

I haven't been able to make this work. If I've understood right, refinery checks for vespene geyser by using validator 'Has Vespene'. I don't want my main building dummy unit to have harvestable resources, and I don't want it to say 'Vespene: 1250', so I can't use same validator with my unit. Is there a way to make validator to check for specific unit? Are there any validator tutorials out there? All help is appreciated. If there is an easier way to implement the functionality I'm looking for, please let me know.

Hi,

go to the units tab, select your main building, and go to the field "Behaviour - Built on" and select your dummy building - thats all. i tested it and had to build my barracks on top of a starport
