My first RayCaster with miniLibX

cub3D (February 2022)

My first RayCaster with miniLibX.

This project is inspired by the world-famous Wolfenstein 3D game, which was the first FPS ever.
It will enable you to explore ray-casting.
Your goal will be to make a dynamic view inside a maze, in which you’ll have to find your way.

Short description of the project

This project’s objectives are similar to all this first year’s objectives: Rigor, use of C, use of basic algorithms, information research etc.

As a graphic design project, cub3D will enable you to improve your skills in these areas: windows, colors, events, fill shapes, etc.

To conclude cub3D is a remarkable playground to explore the playful practical applications of mathematics without having to understand the specifics.

With the help of the numerous documents available on the internet, you will use mathematics as a tool to create elegant and efficient algorithms.

For the detailed instructions on the project,check the subject.pdf.

Requirements to run the game

only tested on macOS Catalina (Version 10.15.7)
For all other OS it is not guaranteed to work.
OpenGL and AppKit is required to run it.
If you want to run it on Linux here is a tutorial that might help and here is the required version of miniLibX, this is not tested with our cub3D.

How to cub3D

1. run make or make all in the root of the directory
2. run ./cub3D maps/42.cub in the root of the directory
3. move the character with WASD
4. turn the FOV left and right by pressing arrow_left and arrow_right or by moving the mouse right or left

Things to enjoy

• wall collition
• moving hands while walking
• opening and closing doors by walking into them
• fully customizable maps

Map requirements

• decide which texture is displayed on which side
• 0 define walkable spaces
• 1 define walls
• 2 define doors
• the players position is displayed by:
  • N player is facing north (top of the 2D map)
  • E player is facing east (right side of the 2D map)
  • S player is facing south (bottom of the 2D map)
  • W player us facing west (left side of the 2D map)
• the map has to be enclosed by walls on all sides
• doors have to have walls on two opposite sides
• any other characters other than the ones above are forbidden
• if there is a (space) inside the map it has to be enclosed by walls, as you can see here
• only one player position is allowed
• you have to set all the textures that should be used as wall texture i.e.
  • WE images/1.xpm
  • EA images/2.xpm
  • SO images/3.xpm
  • NO images/4.xpm
• you have to set the ceiling color, i.e.:
  • C 0, 183, 183
• you have to set the floor color, i.e.:
  • F 141, 1, 126

Texture requirements

The wall textures as well as the door texture is interchangeable, as long as:

• the texture is 64 by 64 pixels
• the texture is a .xpm file
• the textures are called 1.xpm, 2.xpm, 3.xpm, 4.xpm, 5.xpm with 5.xpm being the door

If you want to change the windowsize, this can be done in the cub3d.h file.
But the hands are currently not resized to the windowsize, so either you have to resize the texture itself and replace the existing hand-textures in images or just disble the hands by commenting out line 113 in draw.c.
