Yadex $VERSION ($SOURCE_DATE)

Yadex game definition files

Magic string

A file is a valid Yadex game definition file if its first line contains exactly the following characters : "# Yadex game definition file version 2" (without the double quotes).

Contents

The contents are pretty self explanatory. Some things worth noting :

ldt file has changed.

Defines a linedef type.

ldtgroup

Defines a group of linedef types.

level_format

Indicates the format in which levels are stored in the wad. There is only one argument. It can have the following values :

Value	Meaning
alpha	Doom alpha format, 7 directory entries per level (label, FLATNAME, POINTS, LINES, SECTORS and THINGS).
doom	Normal Doom format, 11 directory entries per level (label, THINGS, LINEDEFS, SIDEDEFS, VERTEXES, SEGS, SSECTORS, NODES, SECTORS, REJECT and BLOCKMAP).
hexen	Hexen format, 12 directory entries per level (same as for doom then BEHAVIOR).

Reading is supported for all formats but writing is not supported for hexen. For alpha, writing is done in doom format.

This directive is mandatory. If there are several level_format directives, it's the last one that counts.

level_name

Indicates whether the level names for that game are of the form EnMn or of the form MAPnm. There is only one argument. It can have the following values :

Value	Meaning
e1m1	EnMm (Doom, Doom press release and Heretic).
e1m10	EnMm or EiMjk (Doom alpha only)
map01	MAPnm (Doom II, Hexen and Strife).

The influence of this directive on the behaviour of Yadex is in the choice of the default name for new levels and the way shorthand arguments to the edit and create commands are interpreted.

This directive is mandatory. If there are several level_name directives, it's the last one that counts.

picture_format

Indicates in which format the pictures are stored in the wads. There is only one argument. It can have the following values :

Value	Meaning
alpha	The obsolete format used in Doom alpha 0.2, 0.4 and 0.5.
pr	The obsolete format used in the Doom press release pre-beta.
normal	The normal format used by all other iwads.

This directive is optional. If it's missing, the default is normal. If it's repeated, it's the last occurrence that counts.

st

Defines a sector type.

texture_format

Indicates in which format the textures are stored in the wads. There is only one argument. It can have the following values :

Value	Meaning
nameless	The obsolete format used in Doom alpha 0.4 (no texture names).
strife11	The format used by Strife 1.1 and later. Note that Strife 1.0 uses the regular format (normal).
normal	The normal format used by all other iwads.

This directive is optional. If it's missing, the default is normal. If it's repeated, it's the last occurrence that counts.

texture_lumps

Indicates in which lump(s) is the list of textures for that game. There is only one argument. It can have the following values :

Value	Meaning

none	There is no textures lump (Doom alpha 0.2)
normal	There is TEXTURE1 and optionally TEXTURE2 (all other iwads).

This directive is optional. If it's missing, the default is normal. If it's repeated, it's the last occurrence that counts.
