# cub3d - @42Born2Code

The project is inspired by the world-famous eponymous 90’s game, which was the first FPS ever. The goal its to explore ray-casting with our own libraries. The result is a dynamic view inside a maze, in which the player will have to find their way.

This README is dedicated to our long devoted fans. Enjoy our CUBE.

About

Raycasting project of 42 Madrid

Developed in C by Guille and Joan as part of the common core.

Guillermo Mira [a.k.a. guilmira] Github: https://github.com/guilmira Joan Sanfelipe [a.k.a. jsanfeli] Github: https://github.com/KiriamBlu

Requirements

The only requirements are:

• GNU make (v3.81)
• GCC (v4.2.1)
• MLX (v2.2.0)
• glfw library

Those versions are the ones used during development.

Building the program

Only available for Linux´s main distributions.

1. Download/Clone this repo git clone -recurse-submodules -j https://github.com/guilmira/cub3d.git
2. cd into the root directory cd cub3d
3. make install to install all requirements make install

Running the program

First run (default)

-For Darwin(default) Just by executing make exe for Darwin distribution will compile and run the program. Enjoy. make exe

-For Arch
	make ARCH

-Rest of Linux distributions
	make LINUX

Custom run

After building the source, run ./cub3D main_map.cub from the project root. This will execute the CUBE with the default map built by developers. This is a middle-size map that shows all the basic features of the pproject such as, raycasted walls, collisions, player movement and minimap.

Customizing your own map

main_map.cub is nothing but an argument. If the user wants to build their own custom map, the rules to built it are the following:

Type of file:

Nothing more than a simple text file. The extension should be ".cub". For example: "map.cub"

Texture:

In the folder textures, you can include whatever .png file that u wish. In order to include it in the file, u must add the extension in the text file. For example
	north textures/example_texture1.png
	south textures/example_texture2.png
	east textures/example_texture3.png
	west textures/example_texture4.png

Map rules:

The perimeter map must be fully closed by walls. And the only elements allowed are the following:
1				means wall.
0				means playeable space.
'N' 'E' 'W' 'S'	means player orientation. 

Player position and orientation:

'N' 'E' 'W' 'S'	means player orientation. 

Sky colour and sky floor:

RGB means red, green and blue. Values given as a parameter can only go from 0 to 255 in all cases.
A value of (255, 0, 0) means full red.

You have to add the colours by following the RGB standard as in the example:
C 40,40,40
F 151,151,151

Controls:

W A S D ▶️ to move through the map
⬅ ⭕ ➡️ to rotate the camera

Example:

north textures/first_brick_layer.png
south textures/second_brick_layer.png
east textures/third_brick_layer.png
west textures/fourth_brick_layer.png
  
F 151,151,151
C 40,40,40

1111111
1000011
1000011
10N0111
1000111
1000111
11111

As you can see from the example above, the map does not have to be necessarily a regular square.
