You start with a sheild controller, this would be the main computer controller of all the sheilds on the ship, you then have sheild generators, these would replace the dispersers and would be able to be placed anywhere on a ship or station and would not have a box dimension effect, the generators would then be linked to a sheild emitter which would have to be placed on the exterior layer of the ship or station, a sheild emitter would have enhancers to adjust the size just like the docking system. Each sheild emitter would have a protection zone and could be scaled by adding generators to it. The emitters would be vulnerable to hits based on the skill of a pilot, if you can hit the emitter you can knock it out, if you knock out enough of the emitters then a capital ship would be vulnerable to actual hull damage. The controller would come into play as a routing tool, if an emitter were knocked out, the controller would move the generators from that emitter to the adjacent emitters to compensate for the emitter that was knocked out.
The math on the sheilds would be pretty easy,
1. the emitter is placed as an exterior ship block,
2. behind the emitter would be the enhancer to adjust the size, 2 blocks in the direction the block is placed.
3. sheild generators linked to the emitter, any location on the ship, as they are linked the sheild strength/regen is increased based on the old style sheild dispensers.
4. sheild controller, optional, if you have a controller, if an emitter is knocked out, the controller would add the enhancers and generators to the adjacent emitters to increase the size of those emitters arrays to cover the space of the knocked out emitter.
This concept allows for all the tactic guys with the fighter type mentality to attack and not only damage but disable a capital ship, it also allows a capital ship to attack another capital ship and knock out the emitters. If your a good shot you can win if not you can run. This also makes planning and building a ship more intricate, you cant just put in a square block of dispensers and have the op sheilds, you have to actually plan your ship around emitters, enhancers and generators as well as the power requirements to keep them up.
