i\'ve been working on some more pictures and have created these to show how things would connect and the sizes.
sorry for the pictures being so small.
the bright green sphere is a sphere for a turret and the darker green box (might not be visible) is a general block size
the blue cylinder is a retracter for turrets, and the red box (again might not be visible) is the general block size.
the bright green sphere is the turret sphere, the blue cylinder is the retracting block, however when it is attached to a sphere i extends slightly to cover half of the sphere. and again the red boxes show the general block size.
Notes:
the retracter does not have to be cylindrical however it is for this turret,
and, i\'m not sure how many blocks the sphere should cover:
1x1 so it only uses one block for the sphere and one for the cylinder, this would make attached cannons look out of place, or,
3x3 so the antimatter cannons fit in the center block and there is 1 block all around the outside, (this would mean the use of only one retracting block still, but it could be a larger one.)
both sizes would only have a few antimatter cannons attached (say 5 for example), because you don\'t really want loads of overpowered turrets that can nearly hit you wherever you are, and too many would cause the line of AMCs to keep hitting things.
sorry for the long post that may keep contradicting itself, i just had a lot to explain.
