so_long

A 42 graphical project: a small 2D game built with the MiniLibX library where the player navigates a maze, collects items, and reaches the exit.

Features

• Loads and parses a maze from a .ber map file
• Keyboard-controlled character movement
• Collectible items + exit unlocking
• Tile-based rendering via MiniLibX
• Map validation, including a DFS path-checking algorithm to confirm the map is solvable

Build

make

Requires MiniLibX — see the MiniLibX docs for installation.

Run

./so_long maps/valid/map.ber

Map format

A valid .ber file uses the following tiles:

Char	Meaning
1	Wall
0	Empty space
C	Collectible item
E	Exit
P	Player start

The map must be rectangular, fully enclosed by walls, and contain exactly one P, at least one C, and at least one E.

Layout

• so_long.c, so_long.h — entry point and headers
• parser.c, parser2.c — map file parsing and validation
• dfs.c — depth-first path check (confirms P can reach every C and the E)
• keyhooks.c — keyboard input handling
• utils/ — helper functions
• img/ — sprite assets
• maps/ — sample valid and invalid maps
• mlx/ — MiniLibX
