I have two state machines. They are pretty much the same. I have two AI players. One state machine for each player. The state machines are for base building.

I have three maps. One map for AI player 1 and one map for AI player 2.

Because the state machines are identical the base building takes place the same for both players. They evolve the same at the same time.

On the third map I have a third player.

Player 1 has advanced AI or emergent AI. Player 2 is scripted.

Player 3 doesn't see what the other two players are doing. It has a limited base building state machine. Player 3 is a limited sincronization with Player 2. Player 3 is what player 1 is seeing that player 2 is doing. When the player 1 sees player 2 units the units that are spotted are sincronized on the third map everything else on the third map is run by the third limited state machine.

Map 1 and map 2 is the same map. They`re more like viewports. Map 1 is for displaying what player 1 is doing and map 2 for displaying what player 2 is doing. Map 3 is the same map with map 1 and 2 but it doesn't have players 1 and 2 it has player three which is a partial sincronization with player 2. Map 3 helps player 1 understand what player 2 is doing.

Here`s an example. The game begins. Player 1 workers begin mining minerals, they are visible only in Viewport 1 or Map 1. Player 2 workers are also on Map 1 but they are not visible. Player 2 workers begin mining minerals too, they are visible only in Viewport 2 or Map 2 . Map 2 has also Player 1 workers but they are not visible. Player 3 workers begin mining minerals they are present only on Map 3. Map 3 doesn't have Player 1 or 2 units. Ok. All 3 players are mining minerals. Player 2 workers cease to mine minerals and move to the side. Player 1 and 3 keep mining minerals.

Player 1 sends a worker to scout the map. Player 1 discovers Player 2 base. Player 2 base becomes visible in Viewport 1. Player 1 scout worker observes that Player 2 workers are missing from the resource extraction site. Player 3 workers cease to extract minerals. If Player 1 scout worker notices where Player 2 workers have moved Player 3 workers are placed there, if not player 3 workers are placed at a random location on map 3 where Player 1 scout hasn't been yet ( it's not really a random location, you can apply some common sense rules: the workers are not scattered all over the map but rather located somewhere as one compact group )

When Player 1 attacks Player 2 with he will use as a reference Player 3 units. Player 3 units are visible to player 1 at all time.
