heXen:Edge of Chaos will be a new and free game, based on the original Hexen franchise that was developed by id Software and Raven Software. The game utilizes the id Tech 4 GPL engine that id Software released on November 22, 2011. Previously the project was a total conversion for Doom 3.

Edge of Chaos is being developed by a team of fans who have always loved the original Hexen since it came out. In fact, most of us spent countless hours with the entire series. When id Software released Doom3, we immediately saw immense potential in the engine itself; the 'Hell' maps gave us the inspiration to make a hack-and-slash game based, primarily, on the original Hexen. Our story ties into the expansion packs and also touches upon the Heretic narrative; especially the incredible atmosphere painted into these rich worlds and their darkling journeys.

The game will be released in three episodes, each based on one character class. Our first demo release, an excerpt from the first episode, is based on the Cleric class. The second and third episodes will be based on the warrior and sorceress class respectively. We've chosen to use an episodic approach in order to create a manageable release schedule.

You could start it with ./dhewm3 +set fs_game eoc

How to build

On Windows

You need CMake either Visual Studio (2010 and newer have been tested) or MinGW-w64

1. Clone the dhewm3-sdk git repo
2. switch to your git clone's directory: cd dhewm3-sdk
3. (optional: switch to an existing mods branch: git checkout hexeneoc)
4. create a build directory in your dhewm3-sdk/ directory (build/ or build-eoc/ or whatever)
5. Start the CMake GUI
6. Select your dhewm3-sdk/ folder for "Where is the source code" and your
   build directory from step 3 for "Where to build the binaries".
7. Click [Configure], select what you want to build with, e.g. "Visual Studio 15 2017", click [Finish], wait for CMake to do its thing
   • If you're using MinGW you'll have to select your build type now, e.g. Debug (not optimized but debuggable) or Release (optimized and thus faster, but can't be debugged that well).
   • (For Visual Studio you don't have to select a build type now, you can do it in in Visual Studio)
8. Click [Generate]
9. Building:
   • If you're using Visual Studio, you should be able to just click [Open Project] to open the generated Project in Visual Studio. You can now compile the SDK in Visual Studio (and of course make your changes to the code).
   • (Untested:) For MinGW, open your MinGW or MSys shell, switch to your build directory and execute make -j4 to build the game DLL
10. Now it's time to copy the DLL (eoc.dll) to your dhewm3 install, where eoc.dll and d3xp.dll are
    • For Visual Studio the DLL should be in a subdirectory of your build directory, depending on the build type you selected in build/Debug/ or build/Release/ or similar
    • For MinGW the DLL should be directly in your build directory.
11. start the game with that mod, like dhewm3 +set fs_game eoc

(Make sure to actually have the mods game data in the right directory as well; the directory name should be the same as the game lib name, but without .dll, for example dentonmod/ for dentonmod.dll)

On Linux and other Unix-likes

On Linux and similar the following should work (if you have cmake, make and GCC/g++ installed):

1. Clone the dhewm3-sdk git repo
2. switch to your git clone's directory: cd dhewm3-sdk
3. (optional: switch to an existing mods branch: git checkout hexeneoc)
4. create a build directory: mkdir build
5. switch to build directory: cd build
6. create Makefile with CMake: cmake ..
   • by default, this will create an RelWithDebInfo build, which is optimized but still has debug info, so it's somewhat debuggable. You can select another kind of build with cmake -DCMAKE_BUILD_TYPE=Debug .. for a Debug build with less optimization, which will make it easier to debug (but possibly slower). You could also replace "Debug" with "Release" for a proper optimized Release build without any Debug info.
7. compile the mod .so: make -j4
8. it (e.g. eoc.so) should now be in the build/ directory, copy it to your dhewm3 install, where eoc.so and d3xp.so are
9. start the game with that mod, like dhewm3 +set fs_game eoc

(Make sure to actually have the mods game data in the right directory as well; the directory name should be the same as the game lib name, but without .so/.dylib, for example dentonmod/ for dentonmod.so)
