Would it be possible to restrict a section of a weapon turn arc?
IE. Restricting a section of the turn arc so that the area that the weapon can turn and fire is effective divided by two. It's like a naval battleship configuration. The turrets can freely turn a full circle but firing in the direction of the centre of the ship is a big no-no. As such, the turrets could only fire at the two sides.
Edit: You know what? I am such an idiot. I don't need to put a restriction on the turn arcs of the weapons at each of the two ends, I just need to limit the range until the weapons turn onto the control column at the centre.
