eightbittr v0.8.15

EightBittr

Bare-bones, highly modular game engine for 2D 8-bit games.

EightBittr is an in-progress experimental game engine targeted to 8-bit retro 2D games. It's got some great features built-in, such as:

• ⚡ Blazingly fast start times:
  • Lazily-instantiated and -loaded components
  • Lazily-instantiated actor classes with inline POJO sprite declarations
  • <150KB minified / <30KB gzipped TTFI game components
• 🔧 Easy scaffolding for extensible mods, level editors, and random map generation
• 🖐 Touch UI support with schema-driven menus and touchscreen buttons
• 💉 Full testability with dependency-injectable, swappable APIs for data storage and time management

❌ ⚠ EightBittr isn't production ready or well-supported - you're probably better off using a more standard game engine. ⚠ ❌

Running Tests

yarn run test

Tests are written in Mocha and Chai. Their files are written using alongside source files under src/ and named *.test.ts?. Whenever you add, remove, or rename a *.test.t* file under src/, watch will re-run yarn run test:setup to regenerate the list of static test files in test/index.html. You can open that file in a browser to debug through the tests, or run yarn test:run to run them in headless Chrome.
