cub3D - My First RayCaster with miniLibX

This project is a simple RayCaster implemented using miniLibX, allowing you to explore a maze with textured walls. The program is designed to display different wall textures, set floor and ceiling colors, and provide smooth window management. The user can navigate through the maze using arrow keys and close the window cleanly with the ESC key or the red cross on the window frame.

Prerequisites

• The project uses miniLibX, either the version available on the operating system or from its sources.
• The management of the window must be smooth, including changing to another window and minimizing.
• Displayed wall textures vary depending on the wall's facing side (North, South, East, West).
• Floor and ceiling colors can be set to two different ones.

Usage

To run the program, provide a scene description file with the .cub extension as the first argument:

make && ./cub3D path/to/your_scene.cub

Scene Description File

• The map must be composed of only 6 possible characters: 0 for an empty space, 1 for a wall, and N, S, E, or W for the player's start position and spawning orientation.
• The map must be closed/surrounded by walls, and any misconfiguration will result in an error.
• Each type of element in the scene description file can be separated by one or more empty lines.
• Elements can be set in any order in the file, except for the map content, which must be the last.
• Each element's information can be separated by one or more spaces.
• Spaces are valid parts of the map, and the program should handle them appropriately.

Error Handling

• If any misconfiguration is encountered in the file, the program will exit properly and return "Error\n" followed by an explicit error message.
