the game has finished. - Added NOBOSSRIP flag. Note: we are now at flags6! - Added SetSkyScrollSpeed(int skyplane, fixed speed) ACS function. - Added THRUACTORS flag that disables all actor<->actor collision detection. - Added DONTSEEKINVISIBLE flag for missiles that can't home in on invisible targets. - Added SFX_TRANSFERPITCH flag to A_SpawnItemEx. - Added Ultimate Freedoom IWAD detection. - Added GetAirSupply and SetAirSupply functions to ACS. - Fixed: The *surface sound was not played when drowning was switched off by setting the level's air supply to 0.
