Hello potentially dead forum,
I am having an issue with a mission I am working on. I have a mission brain set up to change the warrior brain of a bunch of mechs and vehicles to a patrol brain to move toward a base when you either (a) capture the base HQ or (b) approach the starting point of the relevant vehicles (will probably also add (c) when the base defenders are all destroyed). The movement part is working for both conditions currently implemented, however, when you attack this force en route to the base it does not respond to fire and does not return fire.
Unless I figure out a more elegant solution, I will probably just set them to have an escort brain targeting a Mobile HQ or similar, non-combat vehicle, have a wide scan range to ensure they are ahead of it if the player mechs approach, and just set the movement brain to the Mobile HQ (or whatever).
I have tried the original approach with both a basic patrol brain derived from the original MC2 warrior brains, and one using the universal warrior brain and both have the same problem. Not really a strong coder so if anyone knows of a more elegant solution in .abl I am all ears, otherwise just gonna move ahead with this.
FWIW here is the patrol brain from my most recent attempt:
