lua_bindings.cpp:
- Added new lua_renderer_text_scaled() function
- Wraps renderer->draw_string_scaled() with proper scale support
- Registered as renderer.text_scaled(x, y, text, on, scale)
- Scale parameter defaults to 1 if omitted
Updated all 4 games to use text_scaled():
- simon_says.lua: All text now uses text_scaled with scale=2
- tic_tac_toe.lua: All text now uses text_scaled with scale=2
- memory_match.lua: All text now uses text_scaled with scale=2
- 2048.lua: All text now uses text_scaled with scale=2
This properly uses the C++ renderer's scaled text rendering instead of
workarounds in Lua, providing better performance and consistency.
- 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.
