A bitfield is an integer value treated as a sequence of bits (binary digits) which can be toggled individually as flags. In conventional decimal math, each flag is represented a a power of two number: 1, 2, 4, 8, 16, 32, etc. To toggle each flag, you add them together. The resulting sum is what appears in a variable or structure member.
If it is not apparent already, setting a bitfield to 0 disables all flags.
Notable bitfields include:
- cstat
- cstat (wall)
- ceilingstat
- floorstat
- PROJ_WORKSLIKE
- WEAPONx_FLAGS
- spriteflags
- htflags
- mdflags
- orientation
- bits
- extbits
- LOGO_FLAGS
