/42_cursus_cub3d

My first RayCaster with miniLibX

Primary LanguageC

42_cursus_cub3d

Description
This is my first raycasting project, part of my journey as a Cadet at 42 São Paulo. Inspired by Wolfenstein3D, which was the first FPS game ever, the goal was to make a dynamic view inside a maze, using C language and minilibx. This projects runs on Linux.

Method
I have chosen to use Digital Differential Analysis (DDA) algorithm for all the calculation needed to be able to draw the projeted walls.

How to access

Clone this repository:

git clone git@github.com:clacrisostomo/42_cursus_cub3d.git

Then:

cd 42_cursus_cub3d

Mandatory part

For the mandatory part of this project I had to:

  • render projected walls
  • apply a different texture to the walls according to where they are facing (North, South, East, West)
  • render one type of sprite
  • set two different colours for the floor and ceiling
  • be able to move around the map using W, A, S, D keys and rotate ("look") the view with the left and right keys.
  • be able to close the window using ESC or clicking on the x button.
  • be able to take a screen shot (.bmp file) of the entering view with --save
  • if the resolution set in the map is greater than the screen's, the program should resize the window to the user's screen size.

The maps (.cub files) can be configured like the example below, where:

R 1920 1080 - resolution
NO ./path_to_the_north_texture - North facing wall texture
SO ./path_to_the_south_texture - South facing wall texture
WE ./path_to_the_west_texture - West facing wall texture
EA ./path_to_the_east_texture - East facing wall texture

S ./path_to_the_sprite_texture - sprite texture

F 220,100,0 - floor colour (RGB values)
C 225,30,0 - ceiling colour (RGB values)
