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.
All 4 games (simon_says, tic_tac_toe, memory_match, 2048):
- Changed sizing to use min(width, height) instead of just width
- Grids now scale proportionally on both axes
- All UI text now uses text_scale=2 for better visibility
- Games fill more of the screen properly on portrait mode
Fixes:
- Simon Says buttons now square grid on any orientation
- Tic-Tac-Toe grid centered vertically using full screen height
- Memory Match cards use smallest dimension for square sizing
- 2048 tiles scale and center on both axes
- All text (scores, menus, game over) now 2x larger
simon_says.lua:
- Removed hardcoded button positions
- Added get_buttons() function that calculates button size and position based on screen dimensions
- Buttons now use 10% screen padding and scale to fill available width
- 2x2 grid automatically scales with screen size
tic_tac_toe.lua:
- Replaced hardcoded CELL_SIZE with dynamic calculation
- Added get_cell_size() to compute size based on screen width
- Added get_grid_start_x/y() to center grid both horizontally and vertically
- Grid now scales to fill available space while maintaining 3x3 layout
- All cell positions updated to use dynamic functions
Both games now work on any screen size and scale proportionally.
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.
