A small 2D C++ Game Framework, using few dependencies and simple code to mainain easy building and portability.
โ This will likely see breaking changes! Use at your own risk! โ
- Requires C++17 and CMake 3.14+
- A single Platform implementation must be enabled:
- SDL2 can be enabled in CMake with
BLAH_PLATFORM_SDL2
(default) - WIN32 (UNFINISHED) can be enabled in CMake with
BLAH_PLATFORM_WIN32
- Additional platforms can be added by implementing the Platform Backend
- SDL2 can be enabled in CMake with
- A single Graphics implementation must be enabled:
- OpenGL can be enabled in CMake with
BLAH_GRAPHICS_OPENGL
(default) - D3D11 can be enabled in CMake with
BLAH_GRAPHICS_D3D11
- Additional graphics can be added by implementing the Graphics Backend
- OpenGL can be enabled in CMake with
- There's no Shader abstraction, so the Sprite Batcher has hard-coded GLSL/HLSL. This will need to change.
- Only floatN/mat3x2/mat4x4 uniforms are supported.
- There's no Audio API or backend implementation yet.
- No threaded rendering so it will explode if you try that.
