- Added rclamp(<int>,<int>).
- Usable for DECORATE expressions. Chooses one of the two numbers placed in the field.
- Renamed RClamp to Pick.
- Pick can now hold unlimited numbers to choose from.
- I.e. pick(1,4,12,16)
- fixed: FxPick leaked the array's content. Also did some cleanup on FxPick code.
- Fixed: The new HIT* flags were checking the wrong actor.
- Added flags for A_CheckLOF:
- CLOFF_SETTARGET | CLOFF_SETMASTER | CLOFF_SETTRACER
- An actor that causes A_CheckLOF (and only an actor) to succeed will set the intercepting actor as its target, master, and/or tracer, respectively.
- Added HIT* flag detection for bullet and rail attacks.
- Need to set it on the puff itself, not the defaults.
