Cub3D is a recreation of the classic game using the C programming language and the Raycasting technique.

1 - Clone or download the repository
2 - Navigate to the project directory
3 - Run 'make' to compile the game
To run the game, use the following command:
./cub3D [map_file]
where map_file is the path to the map file to be used.
The map file should be a plain text file with the following format:
NO [texture_path]
SO [texture_path]
WE [texture_path]
EA [texture_path]
F [color]
C [color]
[map]
where:
. NO, SO, WE, EA: North, South, West, East textures (optional)
. F: Floor color (required)
. C: Ceiling color (required)
. map: Map data (required)
The map data should be a grid of characters representing the different elements in the game world:
0: Empty space
1: Wall
N,S,W,E : player
. W/A/S/D: Move forward/left/backward/right
raycasting technique to render walls in a 3D environment. The 'cast_hrzntal_rays' and 'cast_vrtcal_rays' functions are responsible for casting the rays and calculating the intersection points with the horizontal and vertical walls, respectively. The 'searchto_wall_hrzntl' and 'searchto_wall_vrtcl' functions then search for the walls along the rays until they reach the end of the map or intersect with a wall. The resulting intersection points are used to determine the visibility and appearance of the walls on the screen
the DDA (Digital Differential Analyzer) algorithm to draw a line between two points in a 2D environment. The 'dda' function takes in the 'cub' structure (which contains the necessary information for the program), the starting x and y coordinates, and calculates the distance between the two points. It then determines the number of steps needed to draw the line and calculates the increment in x and y coordinates for each step. Finally, it iterates over the number of steps and draws the line on the screen using the 'my_mlx_pixel_put' function.
