Two SEXPs, non of 'em actually AI-code related, but still.
is-ai-chased-flip: ( probably a stupid name for it...)
would make the ai fighter flip by 180 deg. to meet the threat behind it, WITHOUT changing the vector or the speed, it would be like glide.
would make the AI make instant sharp turns, by 90 deg to any ( maybe changeable ) direction ( like fly in any direction, hit glide, turn by 90 deg. up, down, left or right and disengage glide again ).
This is already possible using the existing SEXPs, but in the most cases you have to set up waypoints for the AI to follow if you want them to make strafe runs.
The two SEXPs would allow the Glide behaviour without the need for waypoints.
It would make the AI less...predictable in games that actually use glide, like Diaspora, BtRL, TBP and WC Saga.
