Hello. Is this thing on? Ok.
So I've heard from several posts that ships can have not only aggressive type depend on officers or orders, but also a size kind of ai? Is it true that frigate with, say, same stats of destroyer, will act differently? I do a quick search in config and ship data in the game directory and didn't find any frigate_ai or destroyer_ai. I ask because I want to change destroyer ai to frigate ai to shrike and see how will it behave.
1) I don't believe this is a thing, though I could be wrong. Ship AI is highly complicated and affected by lots of fundamental features, but I have never heard anywhere that the hullsize of a ship affects its AI in anyway. The one exception for this is fighters ("FIGHTER" being its own hullsize), which have a unique AI - or, well, several AIs depending on the type of fighter - for their flight and attack patterns. Regular warships though, I don't think hullsize directly affects AI.
2) This isn't really a fitting question for this thread. It's certainly not a newbie question. You'd be better off asking this in the
Modding category, as far as "what happens when I modify X vanilla files".*
*By the way, I strongly do NOT recommend modifying vanilla files unless you know exactly what you're doing, and certainly not in this way. Whether hullsize affects AI usage of a ship or not, it certainly affects other factors - first and foremost the cost and availability of hullmods, which will heavily affect the balance of a ship like the Shrike. If you are having trouble with a Shrike not being aggressive enough (and putting an Aggressive or Reckless officer on board isn't cutting it), then you either need to adjust the weapons it's carrying - which also affects AI - or give it some "Eliminate" orders in combat.
(Honestly I'm surprised to hear someone having this issue, since most of what I hear about the Shrike from people is that it's already TOO aggressive and dies way too easily by overextending.
