Ok, so the map is basically two cities facing each other, each one with its own gate, now what i want is an efficient gate system, i already have one but its buggy. I need to open and close the gate by a lever only a specific player controls, another lever that would take gold and lumber to repair gate, and i want that when the gate is destroyed the first lever becomes un active. it would also be great if the gate thing would be disabled if computer players are detected.
