Very hard question. Maybe somebody has a solution. I have a player ship on top layer with paralax 0,0. I have a scroller sprite to make the screen scroll horizontally. since my ship is on paralx 0,0 it can fly in all the screen arround and in the same time the entire environment is side scrolling. I have a turret. But it is not shooting on the ship since it seems for the turret that the ship is very far away for the paralx 0,0. If i put a super big number in RANGE, it shoots...but NOt on the ship.... is there a solution ?
