$$M Fileformat

The $$M fileformat is an intermediate format between WMP and WMB. It is used by WED to communicate with the map compiler. All WED groups are resolved into individual entities.

General format

C++ style comments are supported, i.e. any characters between // and the end of line are ignored. The first token must be a version header after that blocks can appear in arbitrary order.

Header:

version 711

Blocks

A block looks like this:

{
   BLOCKTYPE
   [BLOCKSPECIFIC DATA...]
}

Block types

0 = World geometry

1 = Position

2 = Light

3 = Static entity

4 = Sound

5 = Sun (and general level information)

6 = Path

7 = Dynamic entity

World block

The world block (type 0) specifies the intermediate WAD file ($$W) and the palette file to be used. After that geometry blocks are defined.

{
   0
   FILENAME.$$W
   PALETTE.PCX
   { 
      // first geometry block
   }
   { 
      // second geometry block
   }
   [..more geometry blocks..]
}

Geometry blocks

{
  vertices NUMVERTICES
  faces NUMFACES
  VERTEX0_X VERTEX0_Y VERTEX0_Z    VERTEX1_X VERTEX1_Y VERTEX1_Z 
  [..more vertices..]
  FACE0_VERTEXCOUNT VERTEX0 VERTEX1 [..] : TEXTURENAME TEXVEC0 TEXVEC1 : FLAGS AMBIENT ALBEDO ndef
  [..more faces..]
}
