DuDuHoX

Making a maze game in order to learn Haskell.

Game

Player is represented by '@'.
Player can move around pressing W, A, S and D keys.
- Can move only on top of walkable floor (represented by '.').
Player can quit the game pressing Q key.
To win the game, move on top of exit (represented by '!').

Movement: W, A, S, D.
Quitting: Q.
Winning: Moving onto '!'.
World parsing: Matrix of char -> World.
Line of sight: Bresenham's algorithm.
Fog of war: Seen objects are grayed out when they go out of sight.
Draw walkable floor: Walkable floor ('.') is not the same as empty space (' '); Empty space do not block vision but can't be moved onto.
User interface (world display area, controls, message area): ASCII art.
World scrolling: Player is always at the center of the screen.
Console user interface: For old school lovers, has a buffer problem on Windows, need to press enter after every move.
OpenGL user interface: Not super sexy, but has nicer graphics than the Console version, no buffer problems on Windows and a move-transition animation.
- Background music: over-bad OpenMPT music made by the greatest composer of all history: myself.
- Animation: the player has an animation of two sprites.

Improve user interfaces code: Make a core game module that handles the state of the game. The user interfaces modules should only provide "receive input" and "render" functions.
Improve OpenGL user interface code: make a monad, just like DuDuHoXConsoleM, but for the OpenGL version that handles, for example, textures.
Improve animations on OpenGL interface.
- OpenGL user interface code is really ugly :(
Add support for joystick.
Graphical world editing: Create new worlds inside the game.
Save game: Save your progress and resume later.
Interactive objects: keys and doors.
Circuits: Add levers connected to doors.
