All games had the same issue: renderer.circle() requires integer arguments,
but float calculations produced non-integer coordinates.
Fixed in all games using math.floor(x + 0.5) for proper rounding:
- pong.lua: Ball position
- air_hockey.lua: Puck position
- asteroids.lua: Asteroid positions
- ball.lua: Ball and trail positions, velocity line
- breakout.lua: Ball position
- flappy_bird.lua: Bird Y position
- counter.lua: Last touch marker position
- snake.lua: Food position (center calculation)
- tic_tac_toe.lua: O circle center position
Also fixed floating-point coordinate calculations in ball and line
drawing to ensure all coordinates are integers.
- Added INPUT_FRAME_TICK event type to input_event.h
- Added wants_frame_updates() virtual method to Game base class
- Implemented frame tick logic in main loop (basic1.cpp and emulator/main.cpp)
- Added Lua bindings: game.set_frame_updates(bool) and INPUT.FRAME_TICK
- Updated LuaGame to support frame updates via registry flag
- Updated ball.lua to use continuous frame updates for smooth animation
- Both hardware and emulator now support continuous animation for physics/games
- Integrated Lua 5.4 engine (32-bit mode for embedded ARM)
- Created LuaGame wrapper class implementing Game interface
- Added C++ bindings exposing renderer, game state, and input to Lua
- Implemented SD card loader for automatic .lua game discovery
- Updated GameLauncher to support std::function for lambda captures
- Made Game class members public for Lua bindings access
- Added example Lua games: counter, snake, bouncing ball
- Included comprehensive API documentation
Games can now be written as .lua text files on SD card and loaded
without recompilation. Build size: 747KB UF2, Lua VM uses ~50-80KB RAM.
