can someone make me this trigger cos i cant

can someone make me this trigger cos i cant

i try to make a trigger that allows u to use ur team mates buidlings and vice versa so help me ffs

player - make player A treat player B as an ally with shared vision and full shared units.

but i want that u can only use BUIDLINGS not units of allies

make it so that when a building is built, it's given to a third-party player (so to speak) that both players can control. have the buildings sell units instead of train them, so that u get the units and not the third-party player.
