This is a Game Engine/Framework, originally developed for GHdeducted (a 2D game), but has since expanded it's scope to be more generic. For example it also includes 3D stuff, instead of just 2D. Furthermore it got stripped of some dependency heavy dependencies (yea that's a thing).

The initial Developers are Erik Scholz and Felix Richter. Currently developed and maintained by Erik Scholz.

The private repo had over 900 commits, before the first public release.

Links

• Gitlab
• Github
• Setup
• Example Game Setup
• mm_template (a GitHub Template for quick starting MM game dev)
• The Docs Directory contains Documentation loosely based on the Source structure.
• Engine Extensions:
  • Box2D integration
  • fx_draw (simple line drawing rendertask)
• Projects using the Engine:
  • miniTD
  • LiteParticles2DDemo
  • mm_fireworks

Platforms

• PC (Linux, Windows and maybe APPLE(compiles))
• Android (untested)
• Web (huh? yea! via Emscripten, wasm and WebGL2)
• anything if you put your mind to it....
• Rendering wise, only Opengl3.3/ES3 is included in the Engine

Roadmap

• Rewrite the Input service (the code was ported in and is older than the Engine (2017))
• Extend the SDL service with Vulkan support (it's 2020 so yea)(man it's 2022 and not done)
• Filesystem refactor (like a proper file type, with destructor and stuff)
• l10n support
• ImGui integration refactor (for making it usable as a game ui, not just for debugging)
• more service interfaces (with focus on networking)
• multithreading updates (maybe a jobsystem idk)

Limitations

• Features in general. It's more of a Personal Framework than something I want everyone to use ;).
• Only ships where OpenGL 3.3 or OpenGL ES 3 are available (includes web via Emscripten's ES3 emulation)
• not optimized for performance
• no multithreading in the Engine itself
• basically most of the Roadmap fits here too
