Updated games:
- pong.lua: All text now uses text_scaled with scale=2
- air_hockey.lua: All text now uses text_scaled with scale=2
- asteroids.lua: All text now uses text_scaled with scale=2
- ball.lua: All text now uses text_scaled with scale=2
- breakout.lua: All text now uses text_scaled with scale=2
- counter.lua: All text now uses text_scaled with scale=2
- flappy_bird.lua: All text now uses text_scaled with scale=2
- lunar_lander.lua: All text now uses text_scaled with scale=2
- snake.lua: All text now uses text_scaled with scale=2
- tetris.lua: All text now uses text_scaled with scale=2
All 14 games now have consistent 2x text scaling for better readability.
snake.lua:
- Changed wall collision to wrap around (toroidal grid)
- Snake now travels through edges instead of crashing
- Doubled move_speed from 10 to 20 frames (half speed)
- Updated speed increase cap from 3 to 5 frames (slower at max)
- Snake can now traverse indefinitely without losing to walls
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.
- 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.
