MAP Files

Maps are generally stored in ASCII text files. The file-format is based on the Quake map format.

Entity:

 {
 "key" "value"
 ...
 }

General Entity Values:

• classname: gives the name for the entity
• origin: gives the location of the entity
• angle: gives the angle of the entity, generally 0-360 or -1 or -2 for up/down.
• target: what is triggered by this entity
• targetname: name used to refer to this entity (or a group of entities)
• ...

Entity Classes:

• worldspawn
  • Defines the main world
  • "sky": Gives the skybox
• info_player_start
  • Says where the player should spawn
• random_terrain
  • Map uses voxel terrain.
  • This is stored as a grid of regions keyed to the name of the map.
• light
  • Light source
• light_sunrel
  • Defines the sun.
  • Position is defined relative to that of the player.
• ...

Which may contain brush definitions:

 {
  ( x0 y0 z0 ) ( x1 y1 z1 ) ( x2 y2 z2 ) texture xoffs yoffs angle xscale yscale
  ...
 }

Texture names are generally interpreted as being a path within the textures tree.

The 3 vertices define a plane face, and the plane faces will intersect to define a solid brush. Alternatively, Valve220 style brush faces may be used:

 ( x0 y0 z0 ) ( x1 y1 z1 ) ( x2 y2 z2 ) texture [ sx sy sz soffs ] [ tx ty tz toffs ]

These define the face's texture orientation in terms of a pair of vectors.
