No game yet, nothing even close. I'm in the very early stages of trying to understand the various file formats. Until then, you can play WH40K: Chaos Gate in a WinXP VM, disconnected from the internet. It doesn't need 3D rendering!

WH40K.exe is the existing game engine, and WH40K_TD.exe is the map editor. Allows things to be saved as .MAP or as .SMF ("Super Macro File").

Building from source

I'm writing code in Go at the moment, so you'll need to have a Go runtime installed on your system:

$ go version
go version go1.10 linux/amd64

In addition, you'll also need the following packages installed, at least in Debian:

apt-get install libx11-dev libxcursor-dev mesa-common-dev libxrandr-dev \
  libxinerama-dev libgl1-mesa-dev libxi-dev

Clone the source tree to $GOPATH/src/ur.gs/ordoor. You can then run make all to get the binaries that exist at present.

They're not very interesting :D.

Place your WH40K: Chaos Gate installation in ./orig to benefit from automatic path defaults. Otherwise, point to it with -game-path

The view-map binary attempts to render a map, and is the current focus of effort. Once I can render a whole map, including pre-placed characters (cultist scum), things can start to get more interesting.

Current status: map tiles are rendered at correct offsets. Static objects (four per map coordinate: floor, centre, left, and right) are rendered mostly fine, although objects at each Z level don't quite stack correctly on top of each other yet.

Characters and animations aren't touched at all yet. Rendering performance is atrocious. No gameplay, no sound, no campaign logic. Interaction with the play area is minimal and limited to pan, zoom, and click for basic console output.

Still, I'm proud of myself.

To run:

$ make view-map
$ ./view-map -map orig/Maps/Chapter01.MAP -txt orig/Maps/Chapter01.TXT

Looks like this:

Use the arrow keys to scroll around the map, the mouse wheel to zoom, and the 1 - 7 keys to change Z level.

Dependency management uses govendor. Unless you're contributing code you shouldn't have to worry about it.

dep bug https://github.com/golang/dep/issues/1725 means I can't use it.

Miscellany

"Mission Setup" includes information about available squad types

From EquipDef.cpp Dumo: CEquipment we learn the following object types:

DELETED
WEAPON
GRENADE
MEDIPACK
SCANNER
GENESEED
CLIP
DOOR KEY
DOOR KEY

And we learn they can be "on"....

CHARACTER
