My first RayCaster with miniLibX

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.

Mandatory part

Program name	cub3D
Turn in files	All your files
Arguments	a map in format *.cub
External functs.	open, close, read, write,printf, malloc, free, perror, strerror, exit • All functions of the math library (-lm man man 3 math) • All functions of the MinilibX
Libft authorized	Yes
Description	You must create a “realistic” 3D graphical representation of the inside of a maze from a first-person perspective. You have to create this representation using the Ray-Casting principles mentioned earlier.

The constraints are as follows:

• You must use the miniLibX. Either the version that is available on the operating system, or from its sources. If you choose to work with the sources, you will need to apply the same rules for your libft as those written above in Common Instructions part

• The management of your window must remain smooth: changing to another window, minimizing, etc.

• Display different wall textures (the choice is yours) that vary depending on which side the wall is facing (North, South, East, West)

• Your program must be able to set the floor and ceiling colors to two different ones

Game

• The program displays the image in a window and respects the following rules:

  ◦ The left and right arrow keys of the keyboard must allow you to look left and right in the maze. ◦ The W, A, S, and D keys must allow you to move the point of view through the maze. ◦ Pressing ESC must close the window and quit the program cleanly. ◦ Clicking on the red cross on the window’s frame must close the window and quit the program cleanly. ◦ The use of images of the minilibX is strongly recommended.

Map

• Your program must take as a first argument a scene description file with the .cub extension.

• The map must be composed of only 6 possible characters: 0 for an empty space, 1 for a wall, and N,S,E or W for the player’s start position and spawning orientation. This is a simple valid map

  111111
  100101
  101001
  1100N1
  111111

• The map must be closed/surrounded by walls, if not the program must return an error.

• Except for the map content, each type of element can be separated by one or more empty line(s).

• Except for the map content which always has to be the last, each type of element can be set in any order in the file.

• Except for the map, each type of information from an element can be separated by one or more space(s).

• The map must be parsed as it looks in the file. Spaces are a valid part of the map and are up to you to handle. You must be able to parse any kind of map, as long as it respects the rules of the map.

• Each element (except the map) firsts information is the type identifier (composed by one or two character(s)), followed by all specific informations for each object in a strict order such as:

  • North texture: NO ./path_to_the_north_texture identifier: NO path to the north texure

  • South texture: SO ./path_to_the_south_texture identifier: SO path to the south texure

  • West texture: WE ./path_to_the_west_texture identifier: WE path to the west texure

  • East texture: EA ./path_to_the_east_texture identifier: EA path to the east texure

  • Floor color: F 220,100,0 identifier: F R,G,B colors in range [0,255]: 0, 255, 255

  • Ceiling color: C 225,30,0 identifier: C R,G,B colors in range [0,255]: 0, 255, 255

• Example of the mandatory part with a minimalist .cub scene:

  NO ./path_to_the_north_texture
  SO ./path_to_the_south_texture
  WE ./path_to_the_west_texture
  EA ./path_to_the_east_texture
  F 220,100,0
  C 225,30,0
  1111111111111111111111111
  1000000000110000000000001
  1011000001110000000000001
  1001000000000000000000001
  111111111011000001110000000000001

  11110111111111011101010010001

  10000000000000001101010010001
  11000001110101011111011110N0111
  11110111 1110101 101111010001
  11111111 1111111 111111111111

If any misconfiguration of any kind is encountered in the file, the program must exit properly and return "Error\n" followed by an explicit error message of your choice.

Bonus part

Bonus list:
