Next example:
In next version AI needs to calculate where to move. To do this AI give question to Battleground: “Can I move 3 times left and 1 time bottom?”. If true it responds: “Move bot from x,y 3 times left and 1 time bottom.” and Battleground should calculate new position (x and y). Fetch item from grid, remove it (replace with nil) and “move” (replace nil with item - struct - in new coords).
