This is CUB3D, a C project of the school 42 common core, and the second graphics project after FRACT-OL. Just like the latter, CUB3D uses the MinilibX. The goal is to create a game in "3D" using the method of raycasting, inspired by the game Wolfenstein 3D. The method I chose uses trigonometry; it is more detailed in this tutorial: https://permadi.com/1996/05/ray-casting-tutorial-table-of-contents/
Warning: this project was coded on and for MacOS. If you're on a different OS, you might need to make some adjustments.
The goal is to be able to move through a maze, using the arrow keys. The walls should have textures and the floor and ceiling should be one color. Anything added is a bonus. The program takes a map as a parameter on the command line, a few already made maps are available in the repository.
The textures theme I chose is inspired from a famous game (which will not be mentioned by name for copyright reasons):
Among the bonuses I chose to add:
- a minimap in the top right corner of the screen
- collisions against the wall: you cannot walk through the walls
- doors that can be opened or closed (with the space bar)
- the point of view can change with the use of the mouse scroll
I also took the liberty to add a few non-required features (which wasn't listed in the subject requirements or bonuses):
- There are randomly generated frames on the walls: when the map is loaded and displayed, there is a 1/14 chance for each piece of wall that instead of the basic wall texture, it will be a frame (so about 7%). The frame texture is also randomly chosen as 1 of 7. These frames are the ones you can find in the castle from the original game this is inspired from.
- Among the 7 frames, one displays the princess. As you get closer (within a certain distance), it transforms into the famous monster from the same game. There is one real princess frame hidden in the map (not generated randomly): walking into it closes the program, you won!
- A different game mode (playable with the map_tig.cub map), where there's only doors instead of walls, and you have 30 secondes to find the only real door or you're there stuck forever. A chronometer is displayed on the screen. This is achieved through multi-threading.
