Well....sort of! They have a purpose, and are things I can't seem to pin down a definitive answer by searching and 'wikiing'.
Here goes.....

1) Turrets on fighters. Are there limits to how many you can have? I know there were limits to the number of turrets ( or used to be anyway ) so how many could I slap on a fighter?
( I know the guns will be AI controlled....but thats EXACTLY how I want. They will be point defence type flak weapons on a large 1-man type corvette/bomber )
2) IS there ANY reason why a player couldn't fly a capship provided it didn't break the maximum number of turrets allowable. ALL weapons bar fixed forward pointing beams would be under AI control.
3) How do you control the viewpoint from 'external' views. If I were to position this INSIDE the hull of my player directed capship, so it looked out from a cockpit type position, would this work? ( aside from screwing up when you pan....
I have built a couple of test ships with 1,2 and 4 turrets, and these seemed to work fine.
The idea is to 'graduate' the pilot onto flying larger vessels as the storyline unfolds. The corvettes are employed as fleet defence, and carry anti fighter arms and either a single low-power beam or missile batteries for anti-capship duties or to act as 'raiders'. I would ultimately like to graduate to much bigger ships if that were possible. The pilot flyability of a BIG ship would eliminate some of the issues with capship behaviour and allow a couple of key mission ideas to actually be possible! Like destroying a world with the biggest Plasma cannon ever......
