This header file contains the frame flag macros for states, as well as the typedef for translucency maps. Note: In Doom's source code this was also the header file for player weapon sprites, or "psprites" for short.

FF_FRAMEMASK

Bit mask for the frame number

Simple stateless animation

FF_FULLBRIGHT

0x8000 (32768)

FF_TRANSMASK
|
0xf0000 (983040)
|
Bit mask for translucency flags

FF_TRANSSHIFT

|
Number of bits to shift up to convert tr_transxx to TR_TRANSxx
Note: This is also used by the software renderer to convert tr_transxx to an offset in bytes to transtables to get the corresponding transluency table array, as each table happens to be 256 × 256 bytes (65536, 0x10000, or 1<<FF_TRANSSHIFT bytes) in size; e.g.: transtables + ((tr_trans50-1)<<FF_TRANSSHIFT) (or transtables + 262144) points to the translucency table generated using the contents of the TRANS50 lump from srb2.srb.
