And Goodbye — College Game Re-release (SDL2)

A small top‑down game originally built for college coursework, now re-released using SDL2 for portability.

• Rendering, input, and windowing are implemented with SDL2 and SDL2_image.
• Maps are plain-text grids validated at load time.
• Assets are simple XPM bitmaps.

Repository Layout

• Makefile — cross‑platform build (Windows/Linux/macOS)
• src/ — game sources
  • Core: src/and_goodbye.c, src/config.c
  • Map I/O: src/render.c, src/read_fd.c, src/split_string.c
  • Gameplay: src/movement.c, src/validator.c, src/infected_map.c, src/image.c, src/utils.c
• include/ — project headers and vendored SDL headers
  • Project API: include/and_goodbye.h
• img/ — XPM sprites
• maps/ — sample maps (*.ber)
• lib/ and bin/ — Windows SDL2 binaries

Build

Prerequisites:

• Linux/macOS: SDL2 + SDL2_image development packages
  • Debian/Ubuntu: sudo apt install libsdl2-dev libsdl2-image-dev
  • Fedora: sudo dnf install SDL2-devel SDL2_image-devel
  • macOS (Homebrew): brew install sdl2 sdl2_image
• Windows: MinGW-w64 (or MSYS2/mingw), uses bundled DLLs in lib/ and bin/

Commands:

• Build (release): make
• Build (debug): make debug
• Clean objects: make clean

The output binary is and_goodbye (Linux/macOS) or and_goodbye.exe (Windows).

Run

• Linux/macOS:

  • ./and_goodbye maps/map.ber

• Windows:

  • and_goodbye.exe maps\map.ber
  • Ensure SDL2.dll and SDL2_image.dll are on PATH or next to the executable (see bin/).

  

Usage

• The game expects a .ber map file path as the first argument.
• Close the window or use the platform’s standard close action to quit.
• Keyboard handling is implemented in src/movement.c.

Maps

• Sample maps are in maps/.
• Maps must be:
  • Non-empty and rectangular — enforced in src/validator.c
  • Fully surrounded by walls (1) — see walls checks in src/validator.c
• Loading flow:
  • render_map reads the file, accumulates text, and splits lines via split_string, using buffered reads from keep_reading_fd.
• Tile size is defined by IMG_SIZE (currently 32).

Troubleshooting

• "ERROR: FILE NOT FOUND" — the provided map path is wrong or unreadable.
• "ERROR: EMPTY MAP" — the file has no content.
• "Error\nMAP SHOULD BE A RECTANGLE" — inconsistent line lengths.
• "Error\nMAP MUST BE SURROUNDED BY WALLS 1" — outer border is not walls.

On Linux/macOS, missing libraries at link/runtime usually means SDL2/SDL2_image dev/runtime packages aren’t installed.

Notes

• Assets are XPM files referenced in include/and_goodbye.h (e.g., character and environment sprites under img/).
• Windows build uses -I\include\SDL2 -L\lib from the Makefile and links -lmingw32 -lSDL2main -lSDL2 -lSDL2_image.
