NOTE: the 'cgame' executable looks for data in './data' so make sure you run it with the repository root as working directory
test/platformer/main.lua has code for a simple platform game. Shows how to make systems in Lua.
test/keyboard_controlled.{c,h} shows a simple system implemented in C. It allows control of the transform of an object through the arrow keys, M/N keys to rotate and I/K keys to scale. This works even when attached to the camera, in which case I/K can be used to zoom in and out (this is an effect of how transform scaling affects the camera).
Building
CMake should make it easy to set up. GLFW, GLEW, stb_image, LuaJIT, chipmunk, Gorilla Audio are dependencies and are included in ext/. From the repository root,
cmake -E make_directory build
cmake -E chdir build cmake ..
cmake --build build
The above instructions have been tested under OSX with clang+make, and less recently on Linux with gcc+make and Windows with Visual Studio 2013.
Running
After building just run the 'cgame' executable. This is put in the build directory by clang+make, and under build/Debug or build/Release by Visual Studio 2013. Make sure your working directory is the root of the project (cgame looks for core data in './data'). It takes a startup script as the first argument. So after running the commands in the previous section, you could do,
./build/cgame test/platformer/main.lua
There are some other tests in test/. Try test/physics.lua! You could also just fire up cgame with no startup script and write stuff in usr/scratch.lua to code live! It'll run the contents of that file whenever it is modified.
