so_long

In this exercise I have to create a basic 2D game in which a dolphin escapes Earth after
eating some fish. Instead of a dolphin, fish, and the Earth, I can use any character, any
collectible and any place I want.

Program name	so_long
Turn in files	Makefile, so_long.h, so_long.c, so_long_check.c, so_long_display.c, so_long_move.c, so_long_utils.c, maps, textures
Makefile	NAME, all, clean, fclean, re
Arguments	A map in format *.ber
External functions	• open, close, read, write, malloc, free, perror, strerror, exit • All functions of the math library (-lm compiler option, man man 3 math) • All functions of the MiniLibX • ft_printf and any equivalent YOU coded
Libft authorized	Yes

Instructions

Your project must comply with the following rules:

• You must use the MiniLibX. Either the version available on the school machines, or installing it using its sources.
• You have to turn in a Makefile which will compile your source files. It must not relink.
• Your program has to take as parameter a map description file ending with the .ber extension.

Game

• The player’s goal is to collect every collectible present on the map, then escape chosing the shortest possible route.
• The W, A, S, and D keys must be used to move the main character.
• The player should be able to move in these 4 directions: up, down, left, right.
• The player should not be able to move into walls.
• At every move, the current number of movements must be displayed in the shell.
• You have to use a 2D view (top-down or profile).
• The game doesn’t have to be real time.
• Although the given examples show a dolphin theme, you can create the world you want.

Graphic Management

• Your program has to display the image in a window.
• The management of your window must remain smooth (changing to another win- dow, minimizing, and so forth).
• Pressing ESC must close the window and quit the program in a clean way.
• Clicking on the cross on the window’s frame must close the window and quit the program in a clean way.
• The use of the images of the MiniLibX is mandatory.

Map

• The map has to be constructed with 3 components: walls, collectibles, and free space.
• The map can be composed of only these 5 characters:
  0 for an empty space,
  1 for a wall,
  C for a collectible,
  E for a map exit,
  P for the player's starting position.
  
• The map must contain 1 exit, at least 1 collectible, and 1 starting position to be valid.
• The map must be rectangular.
• The map must be closed/surrounded by walls. If it’s not, the program must return an error.
• You have to check if there’s a valid path in the map.
• You must be able to parse any kind of map, as long as it respects the above rules.
• If any misconfiguration of any kind is encountered in the file, the program must exit in a clean way, and return "Error\n" followed by an explicit error message of your choice.
