ANIMATED

From DoomWiki.org

The ANIMATED lump is a Boom feature for defining additional animated walls and flats. Although some modern editors such as SLADE 3 allow to create and edit this lump directly in binary form, the original method devised by TeamTNT involved creating a text file and converting it with a small utility called swantbls (switch and animation tables).

ANIMATED lumps are not cumulative, only the last one loaded will be used.

[edit] Format

The ANIMATED lump makes the names of the animated flats and textures known to the engine. It consists of a list of records, each 23 bytes long, terminated by a record (not used) whose first byte is -1 (255). The terminating record does not need to be complete and may be only the first byte; the rest will be ignored.

Length Description
1 byte 255 to terminate list, 0 if a flat, 1 if a wall texture. ZDoom also uses the value 3 to mark a wall texture allowing decals.
9 bytes Null-terminated string naming last texture/flat in animation.
9 bytes Null-terminated string naming first texture/flat in animation.
4 bytes Animation speed, number of tics between animation changes (little-endian). SMMU and the Eternity Engine use a speed value of 65536 or greater to define warping textures. This feature is also supported by ZDoom.

[edit] Swantbls syntax

The swantbls tool converts a plain text file into an ANIMATED and SWITCHES lump. The format of the plain text file prior to conversion is as follows (quoth defswani.dat):

# This file is input for SWANTBLS.EXE, it specifies the switchnames
# and animated textures and flats usable with BOOM. The output of
# SWANTBLS is two lumps, SWITCHES.LMP and ANIMATED.LMP that should
# be inserted in the PWAD as lumps.
#
#switches usable with each IWAD, 1=SW, 2=registered DOOM, 3=DOOM2
[SWITCHES]
#epi    texture1        texture2
1       SW1BRCOM        SW2BRCOM
...
#animated flats, spd is number of frames between changes
[FLATS]
#spd    last        first
8       NUKAGE3     NUKAGE1
...
#animated textures, spd is number of frames between changes
[TEXTURES]
#spd    last        first
8       BLODGR4     BLODGR1
