It would make a lot of sense to have it be BEHAVIOR::QUEENBULLET along with so many other boss sub-behaviors, I agree, but it has the relatively unique status of being its very own jjObjectPresets slot to contend with. I dunno. More extensive documentation of the various behaviors is a fine idea and also kind of a time-intensive one.

There's no AngelScript access to the camera-shaking code yet, basically because blur seemed to indicate in a comment somewhere that it was more complicated than he'd expected, so I've never taken the time to try it out. You could try shimming something together using jjPLAYER::cameraFreeze, but I don't know offhand how that would interact with the limit x scroll stuff.
