There are 3 random castles on the map. Next to them are buildings that recruit level 7 creatures (random buildings).
I need to connect the buildings and castles so that:
Humans - the building also recruits humans.
Undead - the building recruits undead.
Orcs - the building recruits orcs. I don't understand how to link them - I looked at the example of the "Mysterious Valley" map, but I didn't understand.
I would appreciate your help.
Thank you in advance.
