## blah
A small C++ game framework for 2D games.
Goal is to be simple and use as few dependencies as possible, to maintain easy building and portability.
A small 2D C++ Game Framework, using few dependencies and simple code to mainain easy building and portability.
**☆ This will likely see breaking changes! Use at your own risk! ☆**
#### building
- Requires C++17 and CMake 3.12+
- Platform Backend
- [SDL2](https://github.com/NoelFB/blah/blob/master/src/internal/platform_backend_sdl2.cpp) can be enabled in CMake with `SDL2_ENABLED`, and setting `SDL2_INCLUDE_DIRS` and `SDL2_LIBRARIES`
- Graphics Backend
- [OpenGL](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend_gl.cpp) can be enabled in CMake with `OPENGL_ENABLED`.
- [D3D11](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend_d3d11.cpp) (unfinished) can be enabled in CMake with `D3D11_ENABLED`.
- Other backends can be added by implementing the [Platform Backend](https://github.com/NoelFB/blah/blob/master/src/internal/platform_backend.h) or [Graphics Backend](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend.h).
- A single *Platform* backend must be enabled:
- [SDL2](https://github.com/NoelFB/blah/blob/master/src/internal/platform_backend_sdl2.cpp) can be enabled in CMake with `PLATFORM_SDL2`, and setting `SDL2_INCLUDE_DIRS` and `SDL2_LIBRARIES`
- [WIN32](https://github.com/NoelFB/blah/blob/master/src/internal/platform_backend_win32.cpp) (UNFINISHED) can be enabled in CMake with `PLATFORM_WIN32`.
- Additional backends can be added by implementing the [Platform Backend](https://github.com/NoelFB/blah/blob/master/src/internal/platform_backend.h)
- A single *Graphics* backend must be enabled:
- [OpenGL](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend_gl.cpp) can be enabled in CMake with `GRAPHICS_OPENGL`.
- [D3D11](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend_d3d11.cpp) can be enabled in CMake with `GRAPHICS_D3D11`.
- Additional backends can be added by implementing the [Graphics Backend](https://github.com/NoelFB/blah/blob/master/src/internal/graphics_backend.h).
#### notes
- There's no Shader abstraction, so the [Sprite Batcher](https://github.com/NoelFB/blah/blob/master/include/blah/drawing/batch.h) has hard-coded GLSL/HLSL. This will need to change.
