Follow these conventions to keep builds reproducible and packages shippable. + +## Project shape +- C++20 app using SDL3 + SDL3_ttf via vcpkg. +- Build system: CMake; Windows-focused, but portable with proper toolchain. +- Sources: `src/` (Game.cpp, Scores.cpp, Starfield*.cpp, Audio.cpp, LineEffect.cpp, Font.cpp, SoundEffect.cpp, main.cpp). +- Assets: `assets/` (images/music/fonts), plus `FreeSans.ttf` at repo root. + +## Build and run +- Configure and build Release: + - CMake picks up vcpkg toolchain if found (`VCPKG_ROOT`, local `vcpkg/`, or user path). Required packages: `sdl3`, `sdl3-ttf` (see `vcpkg.json`). + - Typical sequence (PowerShell): `cmake -S . -B build-release -DCMAKE_BUILD_TYPE=Release` then `cmake --build build-release --config Release`. +- Packaging: `.\build-production.ps1` creates `dist/TetrisGame/` with exe, DLLs, assets, README, and ZIP; it can clean via `-Clean` and package-only via `-PackageOnly`. +- MSVC generator builds are under `build-msvc/` when using Visual Studio. + +## Runtime dependencies +- Links: `SDL3::SDL3`, `SDL3_ttf::SDL3_ttf`; on Windows also `mfplat`, `mfreadwrite`, `mfuuid` for media. +- The package step copies `SDL3.dll` and `SDL3_ttf.dll` from `vcpkg_installed/x64-windows/bin/` if present. If changing triplet or layout, update paths in `build-production.ps1`. + +## Key modules and responsibilities +- Game loop and state: `Game.cpp/h` (core), `main.cpp` (entry), `Scores.cpp/h` (high-scores/local), `LineEffect.cpp` (row clear visuals), `Starfield.cpp` and `Starfield3D.cpp` (background effects), `Audio.cpp` + `SoundEffect.cpp` (music/SFX), `Font.cpp` (TTF text rendering). +- Keep drawing and update timing consistent; prefer updating effects modules rather than inlining in `Game.cpp`. + +## Assets and fonts +- Expect `assets/` folder adjacent to the executable; `FreeSans.ttf` is copied next to the exe by packaging scripts. +- When adding assets, ensure packaging script includes new folders/files; use BMP/PNG consistently with existing loaders. + +## Conventions +- C++20, no exceptions policy not enforced; match current code style in each file. +- Use SDL_ttf for text; don’t vendor fonts in code—load from filesystem as done in `Font.cpp`. +- Avoid hardcoding absolute paths; rely on relative paths within the package layout. + +## Useful files +- `CMakeLists.txt` — targets, toolchain detection, link libs. +- `vcpkg.json` and `vcpkg-configuration.json` — dependencies and registry. +- `build-production.ps1` — authoritative packaging steps and expected layout. +- `cmake/ProductionBuild.cmake` — extra flags if needed (included by `CMakeLists.txt`). + +## When extending +- Add new modules under `src/` and register them in `CMakeLists.txt` target sources. +- If new DLLs are required, extend the copy list in `build-production.ps1` and document them in the generated README. +- Validate with a Release build before packaging to catch optimizer-related issues. diff --git a/.github/workflows/build.yml

Grid Line Alignment Fix + +**Problem**: Grid lines were appearing offset (to the right) instead of being properly centered within the game grid, especially noticeable during window resizing and fullscreen mode. + +**Root Cause**: Double application of content offsets - the grid position (`gridX`, `gridY`) already included content offsets, but the grid line drawing code was adding them again. + +#### Before (Incorrect): +```cpp +// Grid lines were offset due to double content offset application +float lineX = gridX + x * finalBlockSize + contentOffsetX; // ❌ contentOffsetX added twice +SDL_RenderLine(renderer, lineX, gridY + contentOffsetY, lineX, gridY + GRID_H + contentOffsetY); +``` + +#### After (Corrected): +```cpp +// Grid lines properly aligned within the grid boundaries +float lineX = gridX + x * finalBlockSize; // ✅ contentOffsetX already in gridX +SDL_RenderLine(renderer, lineX, gridY, lineX, gridY + GRID_H); +``` + +## Technical Details + +### Spawn Position Logic +```cpp +// Standard Tetris spawning with one-line buffer: +// - X position: 3 (center of 10-wide grid) +// - Y position: -1 (one line above top visible row) +// - Rotation: 0 (default orientation) + +Piece newPiece = { pieceType, 0, 3, -1 }; +``` + +### Grid Line Coordinate System +```cpp +// Proper coordinate calculation: +// gridX and gridY already include contentOffsetX/Y for centering +// Grid lines should be relative to these pre-offset coordinates + +// Vertical lines at each column boundary +for (int x = 1; x < Game::COLS; ++x) { + float lineX = gridX + x * finalBlockSize; + SDL_RenderLine(renderer, lineX, gridY, lineX, gridY + GRID_H); +} + +// Horizontal lines at each row boundary +for (int y = 1; y < Game::ROWS; ++y) { + float lineY = gridY + y * finalBlockSize; + SDL_RenderLine(renderer, gridX, lineY, gridX + GRID_W, lineY); +} +``` + +## Benefits + +### 1.

The game now provides an optimal spawn experience with pieces appearing in the 2nd visible line, while the grid lines maintain perfect alignment regardless of window state or size changes.
