Cub3D is a 42 Wolfsburg raycasting project where a pseudo-3D maze is to be rendered and where the user can traverse in.
For this project it was key to implement a parser that processes custom .cub files and to connect it with a graphics rendering module. The latter has a raycaster with a Digital Differential Analysis (DDA) algorithm at its core.
This project was done as a team by:
The program is to parse a .cub file.
This file contains 6 elements and a map.
The elements NO SO WE EA are to be paired with paths for.xpm texture files.
ElementsC and F match with RGB values to render the colors of the ceiling and floor respectively.
The map is to have characters 1 for walls and 0 for empty spaces.
The use of space characters is allowed when not used adjacent to a 0 character.
Finally, the map is also to have N S W or E character for the player's staring position and spatial orientation.
An example of a valid map looks like this:
The user can use the following keys for movement of the player and the camera:
W - Forward movement.
S - Backward movement.
A - Movement to the left.
D - Movement to the right.
LEFT_ARROW - Rotate the camera to the left.
RIGHT_ARROW - Rotate the camera to the right.
The only parameter that is needed for this program to run is path_to_cub_file.
In case of providing an invalid path to a .cub file or by feeding a .cub file with erroneous elements or map, the program displays an appropriate error message.
Errors include for example: Providing a non-closed map, not providing a player starting position and not providing a valid texture file for the walls.
Use make to compile the program.
Add the required parameter:
./cub3D <path_to_cub_file>
Input:
./cub3D maps/test.cub
