GenRefire is a refire check codepointer -- similar to CPosRefire and SpidRefire, it is used to let a monster go back to another state if the target is out of sight, dead or inexistent. Unlike those, it is customizable.
- statenum: mnemonic of frame to jump to when out of sight.
- chance: chance out of 256 that the monster will continue firing even if out of sight.
This codepointer includes a call to FaceTarget. Also, if the actor is FRIEND and has similar fellows in the line of fire, it will switch to statenum without checking for chance.
