Tofu Engine

Welcome!

Guess what? Yup, that's yet another game engine/framework.

Pros

  • Carefully crafted C99 code.
  • Self-contained, no external modules/libraries required (system-wide libraries excluded).
  • Multi-platform through coss-compilation (Windows, Linux and Raspberry-Pi... no MacOS won't be supported, ever).

Dependecies

Features

  • Fully script-based, using Lua.
  • Straight multimedia support, no intermediate third-party libraries (OpenGL 2.1 required).
  • Windowed/fullscreen display with automatic scaling.
  • Internal software renderer.
  • Palette based graphics with up to 256 colors.
  • Predefined library of 8/16/32/64 colors palettes.
  • Automatic nearest-color palette indexing of images.
  • Per-color re-indexing (shifting) and transparency, affecting drawing operations (global, too?).
  • Out-of-the-box timers support.
  • Customizable application icon.
  • Support for archived games, via custom "packed" format (w/ optional encryption).
  • Game-controller support (w/ D-PAD and mouse emulation) w/ keyboard/mouse fallback if not available.
  • Tiled-map support w/ camera support (zoom and scrolling).
  • Screen shaking.
  • Detailed logging facility (w/ logging level throttle).
  • Crash screen (debug build).

Desiderata

  • Bit Block Transfer operations when drawing (also, stencil support, see this).
  • Animation support w/ frameset DSL (i.e. compiling a string where each token can be a single frame, a range or a "keep-current-frame for some time" command). Each frameset can have its one update period, and will be most likely based upon a timer.
  • Audio support (based upon dr-soft/miniaudio) w/ run-time multi-voice synth (a-la Bfxr).
  • Out-of-the-box easing functions (see this and this).
  • Out-of-the-box palette switching (with tweening) features.
  • Game state and display transitions (at which level? Engine or script?).
  • Library of noise functions (cellular, Perlin, etc...).
  • Library of "retro-feel" shaders.
  • Multiple players support.
  • Define some fixed resolutions (see this)?
  • Use a custom memory-management allocator.
  • Switch to Vulkan API (through GLFW).
