This is a small project I developed some years ago. It is an attempt to make a 3D game. The main character is a mouse that lives in a world infested by rats. The project never reached a usable state, but the main character is controllable and parts of the game can be scripted. Missing parts are: inverse kinematics for the mouse to aim and shoot and all the data for the maps and story.
The game engine uses OpenGL 1.4 as my GPU at the time of development only supported this version. It is rather outdated by today's standards, so I would not recommend using this engine as a starting point for a new game. On the graphics side, I still managed to get some interesting effects, such as:
- Stencil shadows (with shadow volume extrusion on the GPU)
- Toon shading (per pixel! -- an achievement obtained using ARB assembly shaders)
- Contours (using a two pass line rendering algorithm)
Even though the provided data files do not contain a collision information for the map
(and consequently, you are able to go through objects -- but not through players), the game supports collision detection for the environment as well.
There is a second map that displays this feature, you can enable it by renaming base/maps1.zip into base/map3.zip.
You will need CMake, SDL, FreeType, Lua, Libjpeg, libpng, and zlib. The project should compile on Linux & Windows, but I will only list the instructions for a Linux installation here:
mkdir build
cd build
cmake ..
make -j
Once the project is compiled, copy the binary in the main directory and enjoy!
Mouse to aim, WASD to move, and ESC to display the in-game menu (with an awesome OpenGL-accelerated UI!)
