Glossary

+ +

It is assumed that some knowledge of DOOM is known by the +reader, but in case here are some general terms that are used in +the documentation.

+ +

DOOM

+ +

If you're unsure what this is, you've probably come to the +wrong place by accident.

+ +

WAD

+ +

A WAD file is the name given to the files used to define the +graphics, sound, music and maps that make up a game of DOOM. WAD +files are split into two different types, IWAD +and PWAD files.

+ +

IWAD

+ +

An IWAD file is is the 'Internal WAD' file. The IWAD file is +the main WAD file as supplied by id Software. +Note that only id Software are meant to produce IWAD files.

+ +

PWAD

+ +

An PWAD file is is the 'Patch WAD' file. This WAD file is read +in by the game after the IWAD file, and an entries in it replace +entries defined in the IWAD file. So for instance a PWAD file +that has an entry for the first MAP will mean +that DOOM will read the first map from the PWAD file, rather than +it's own IWAD file.

+ +

Hmmmm.... Sure I could have explained that better.

+ +

LUMP

+ +

A lump is an entry in a WAD file. For +instance a MAP is made up of a number of +lumps, one defining the sectors for the +map, another the things, and so on.

+ +

MAP

+ +

A map is taken to mean a DOOM level. Note there is two naming +conventions for maps, ExMy +(where x is the episode number, and y the map +number in that episode) used in DOOM and Ultimate DOOM, and MAPnn +(where nn is a number between 01 and 32) used in DOOM 2 +and Final Doom.

+ +

A map is made up of a number of different elements, namely sectors, linedefs, sidedefs, things and vertexes. Following are some (very) basic +definitions for these things, but you would be better reading the +Unofficial DOOM specs for more +accurate definitions.

+ +

MAPs generated in viDOOM must be built with a Node +Builder before they can be used in DOOM.

+ +

Also note that viDOOM supports two different map formats. The +original one, as used in DOOM and DOOM 2, and the extended HEXEN format supported by ZDoom.

+ +

VERTEX

+ +

A vertex is simply an X,Y co-ordinate in the DOOM world.

+ +

THING

+ +

Things are all the different objects on the DOOM map that are +not the actual walls and doors. All the monsters, weapons, ammo, +non-wall based scenery and even your starting point and teleport +locations are all counted as THINGS in DOOM.

+ +

LINEDEF

+ +

A LINEDEF is a line that connects two vertexes. +A LINEDEF at it's most basic is used to make up the walls that +make up the DOOM levels. A LINEDEF must always have a +right SIDEDEF associated with it. 2 sided +LINEDEFS will also have a left SIDEDEF associated with it.

+ +

In addition special types of LINEDEF can be used so that when +the player crosses or activates them actions happen in the DOOM +world - lighting changes, teleportation happens, doors open, +levels are exited and so on.

+ +

SIDEDEF

+ +

A SIDEDEF is basically used to describe the textures +that are painted upon a LINEDEF.

+ +

SECTOR

+ +

Though technically incorrect, it is simplest to picture a +SECTOR as an object enclosed by LINEDEFS. +A sector is used to define the floor and ceiling heights and flats used to draw the floor and ceiling, in +addition to the lighting for that area.

+ +

TEXTURE

+ +

A texture is the graphics used to paint the walls in DOOM.

+ +

FLAT

+ +

A flat is the graphics used to paint the floors and ceiling in +DOOM.

+ +

Node Builder

+ +

Does some of the nastier work of level building by creating +the extra information over and above the parts mentioned in MAPS so that DOOM can actually understand the +level data enough to play it. Note that if you are to edit HEXEN levels you will need a node builder that +understands the different data structures used.

+ +

BSP is perhaps the best known of +these, and the one that was used all through viDOOM's initial +development. When developing the HEXEN edit mode for ZDoom WARM was used.

+ +

HEXEN

+ +

HEXEN is a game by Raven software that uses the DOOM graphics +engine. The WAD format for this is slightly different to DOOM, +having a BEHAVIOR lump for each MAP and +different formats for THINGS and LINEDEFS.

+ +

ZDoom supports this format.
