Simple framework for creating 2D games in C (C++)

Functionality

• Multiple backends (Dynamic/static backends loading at real time) (SDL2, Raylib, Win32)
  
• Libraries config using config.h or preprocessor macros
  
• Window management (SDL2, Raylib)
  
• Renderer (Direct3D, OpenGL, OpenGLES, WebGL, Software) (using SDL2, Raylib)
  
• Image loading (SDL2_image, Raylib, libspng)
  
• Audio (Music/Sounds) playback (SDL2_mixer, Raylib, FMOD, Web)
  
• TTF (TrueType Font) Rendering (SDL2_ttf, Raylib)
  
• Bitmap fonts
  
• LDtk tilemaps import

Is it written in C?

Yes, it it's written in pure C.
It also does some tricks with C to extend its power. For example:

• OOP using structs, function pointers, etc
  
• Magic macros like OMG_INFO which accepts different number of arguments of different types
  
• Things like tracing memory allocation by code file, function, line
  
• Simple error handling using bool return type
  
• Using native win32 api instead of C stdlib on Windows
  
• Many other tricks

Portability

It's only limited to C language and backend libraries. I was able to run examples on:

• from Windows XP (including ReactOS) to Windows 11 (Windows 2000 is only supported with extended kernel)
  
• UWP (Windows 11)
  
• Linux
  
• UNIX (FeeBSD, NetBSD, OpenBSD)
  
• Web (SDL2 + Emscripten)
  
• Android (thanks to SDL2)

Examples

There are some examples.

Simple Example

This one shows main functionality of the framework

Advanced Example

This one shows working with scenes, animations, tilemap rendering

Simple Game

This is a mini-platformer (written in ~3 days) which shows what you can do with my framework
