A prototype game engine that will hopefully one day become the Warfare engine, just a hobby project. It should compile out of the box (all dependencies in-tree).
The engine is written in C (the C11 standard, although I believe it's also valid C99, as of current writing). It aims to be small and clean, with extensibility provided by Lua (through LuaJIT). It is also written with being cross-platform in mind. Although development happens on OS X, no platform-specific functionality has been used, so it should be rather easy to port as long as the platform in question has either Clang (LLVM) or GCC available. (MSVC doesn't understand C11 unfortunately).
This is alpha software, it is not usable yet, I will post an announcement on my website when I'm ready to have the wider world play around with it.
For those of you following at home and reading the source code. All matrices, everywhere are stored in such a way
that columns are contiguous in memory (i.e.: column-major order). This is the native format for OpenGL and it makes
it a bit more efficient to do SIMD operations on matrices. This means that, when you see a matrix you can imagine
that is a float[16], and that (mat[0], mat[1], mat[2], mat[3]) is the first column.
All dependencies are included in-tree and are as cross-platform (or more) as the engine itself.
- SDL2
- LuaJIT
- threedee-simd - I maintain a personal fork, where I'm adding some extra functions, fixes and compiler warning fixes until they are upstreamed.
- stb_image and stb_truetype
For now, just run
$ make -j8If you want a release build, do
$ make -j8 releaseIf you want to make clangd play nice, generate a local compile_commands.json using bear:
$ sudo apt install bear
$ bear -- make CC=path/to/your/clang all- Sean Barrett, creator of stb_image.c and stb_truetype.c, loading images and rendering text have never been so pleasant (and easy to include in a project).
- Samuel Anjam, creator of the BlendELF engine, upon which much of my code and structure is based.
- Tor Andersson, creator of the Mio engine, I learned quite a bit perusing the source when I found it. Its principles seem remarkably similar to the ones I have for this project.
- Mike Pall, creator of LuaJIT, amazing piece of engineering.
- Sam Lantinga, creator of SDL, cross-platform graphics for the masses
- Julien Pommier, creator of sse_mathfun.h, fast transcendental functions!
- Riku Salminen, creator of threedee-simd, the fastest pure 3D math library I know of.
Anyone I might have forgotten, I'm in your debt. If you find that you deserve to be in this list, please shoot me a mail and you'll be added asap!
