so_long

It’s time for you to create a basic computer graphics project!

To start

make && ./so_long.out map.ber

Score

so long will help you improve your skills in the following areas: window management, event handling, colors, textures, and so forth.

You are going to use the school graphical library: the MiniLibX! This library was developed internally and includes basic necessary tools to open a window, create images and deal with keyboard and mouse events.

The other goals are similar to every other goal for this first year: being rigorous, level up in C programming, use basic algorithms, do some information research, and so forth.

Mandatory part

Program name	so_long
Turn in files	Makefile, *.h, *.c, maps, textures
Arguments	A map in format *.ber
External functs.	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
Description	You must create a basic 2D game in which a dolphin escapes Earth after eating some fish. Instead of a dolphin, fish, and the Earth, you can use any character, any collectible and any place you want.

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 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

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.

• Here is a simple valid map:

  1111111111111
  10010000000C1
  1000011111001
  1P0011E000001
  1111111111111

• 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.

• Another example of a minimal .ber map:

  1111111111111111111111111111111111
  1E0000000000000C00000C000000000001
  1010010100100000101001000000010101
  1010010010101010001001000000010101
  1P0000000C00C0000000000000000000C1
  1111111111111111111111111111111111

• 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.

Bonus part

You will get extra points if you:

• Make the player lose when they touch an enemy patrol.

• Add some sprite animation.

• Display the movement count directly on screen instead of writing it in the shell.
