The objective of this project is to create a small 2D game where the player has to collect all the collectibles and go to the exit.

• Use the school's graphic library: MiniLibX! This library was developed in-house and includes basic tools needed to open a window, create images and handle keyboard and mouse events.
• Your program has to take as parameter a map description file ending with the .ber extension.
• 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.
• Your program has to display the image in a window.
• The management of your window must remain smooth (changing to another window, 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.
• 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.

The library is written in C language and thus needs the -cc compiler and some standard C libraries to run.
