Mech Commander 2 open source engine + Linux port.

website

!NB: as russia conducts war in Ukraine I have no time to support this project until we will get rid of orcs. You are encouraged to help.

Disclaimer: I consider this project finished for now, there is a lot more to do for someone who wants to improve the game, but all functionality (except networking) is implemented and I've passed the game on my Linux box. Also found original game bugs and crashes are fixed.

This port is an open source implementation of a closed MC2 engine code using available interface (.h) files. Currently game can be run on both Linux and Windows in 64bit mode. Fixed a lot of bugs (including ones present in original game). Sound system is not fully implemented (panning, doppler, etc. not supported yet)

TODO:

• fix remaining memory leaks (finish implementation of memory heaps)
• make nice data packs, so not only me can play the game :-) (in progress, see data repo
• actually finish all missions in the game
• make sure no files are created outside of user directory
• reduce draw calls number
• reimplement/optimize priority queue
• finish moving lighting to shaders (move whole lighting there, not only shader-based drawing of CPU-prelit vertices like I do now)
• Update graphics to 2018 2020 2021
• Add network support?
• I am sure there is more

Original game was released under Shared Source Limited Permission License (please refer to EULA.txt) My code is licenced under GPL v.3 (see license.txt)

Building on Windows

To build on windows use CMake

Ensure, that you have all necessary dependencies: SDL2, SDL_mixer, zlib, glew I recommend to get zlib sources and build them by hand (do not forget to copy zconf.h)

Just for a reference here is how my 3rdparty tree looks like

|   
+---bin
+---include
|   |   zconf.h
|   |   zlib.h
|   |   
|   +---GL
|   |       eglew.h
|   |       glew.h
|   |       glxew.h
|   |       wglew.h
|   |       
|   \---SDL2
|           all sdl headers (SDL_mixer shiuld be there as well)
|

You may already have your dependencies installed in other place(s), so just make sure CMake knows where to find them.

Now:

git clone https://github.com/alariq/mc2.git
cd mc2
md build64
cd build64
cmake.exe -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH=c:/path_to_your_dependencies/ -DCMAKE_LIBRARY_ARCHITECTURE=x64 ..

(to generate project for VS1027 for 64bit build)

or for 32bit build:

cmake.exe -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH=c:/path_to_your_dependencies/ -DCMAKE_LIBRARY_ARCHITECTURE=x86 ..

Now run generated solution and try to build it!

Now build string resources

First use script in test_scripts/res_conv/res_conv.pl to generate strings.res.cpp and strings.res.h`` files or just take them from that folder Then copy them to ./res``` folder Then:

cd res
md build64
cd build 64
cmake.exe -G "Visual Studio 15 2017 Win64" -DCMAKE_LIBRARY_ARCHITECTURE=x64 ..

put resulting dll along with executable file

Building data

Data files are located in a separate repository Building data is just a matter of executing make command. You can find instruction on how to do it there. But first one needs to build all necessary tools. There are 2 projects which have to be built:

• data_tools
• text_tool

All steps are same as for the main application. As a result you'll have next binaries: aseconv, makefst, makersp, mpak, text_tool. Copy those to the build_scripts folder in mc2srcdata repository.

Once everything in place, you can launch build scripts as described in corresponding README.txt file.

Building on Linux

Dependencies

Apt based distros:

sudo apt install libsdl2-dev, libsdl2-mixer-dev, libsdl2-ttf-dev, libsdl2-mixer-dev, zlib1g-dev, libglew-dev

Build steps

The build process has been reworked to reduce the number of steps and chance of failure. It handles building and moving data and resources into the correct locations at the right time and cloning repositories as required. The game is build in the mc2/build64 directory.

You only need to clone the mc2 directory and the build process will clone the data directory and SDL2 cmake modules for you the first time you run the build process. The mc2 and mc2srcdata projects will be cloned side by side and the build process relies on this. The top level directory structure will look like :

some-empty-directory
|   
+---mc2
\---mc2srcdata

From an empty directory issue the following commands.

git clone https://github.com/alariq/mc2.git
cd mc2

Edit MC2Repos to make sure the git repositories are set to which git repository you want to clone them from. Whoever user's mc2 project that you cloned, set the value for the MC2_DATA_REPO to be that same user. eg. If you cloned alariq's mc2 from https://github.com/alariq/mc2, then set MC2_DATA_REPO to https://github.com/alariq/mc2srcdata.

mkdir build64
cd build64
cmake -DCMAKE_LIBRARY_ARCHITECTURE=x64 ..
make all

cd ../../mc2srcdata/build_scripts
make all BUILD_PLATFORM=linux
./copy_assets.sh

Running on Linux
