- Introduction
-
- Our final project is to design and implement a Gobang game under
- X-Window3.2 environment, using the Haskell programming language. Users
- can play the game human-vs-human. The program also provides a robot
- player with whom the user can play the game with. We wrote altogether
- ten modules which were saved in different files to control the whole
- game.

- About Gobang
-
- The checkerboard of Gobang consists of 19 vertical lines and 19
- horizontal lines. Two players in turn place a unit on the
- checkerboard. Each unit should be put on an unoccupied intersection
- of a vertical and a horizontal line. The winner is the player who
- first makes five consecutive units on either vertical, horizontal or
- diagonal direction.
-
- The program is able to perform the following tasks: 1) Use a new
- window under X-Window interface to display the checkerboard. Players
- will use a mouse to place units onto the chessboard, where a unit is a
- circle with the color black or white. 2) Prompt for the names of both
- players and display them. 3) Calculate the time both players have
- used up. 4) Supervise the progress of the game, declare winner and
- end the game once one player wins. 5) At each point of the game,
- store the progress of the game, so players can review each step during
- the game. 6) There are five buttons on the screen which would provide
- some special services such as starting a new game, quitting the game,
- saving the game, importing the saved game, or reviewing the game as
- soon as the user selects the corresponding buttons. 7) Provide a
- moderately well robot player for that game (using minimum-maximum
- algorithm).

- Running Gobang
-
- A window titled "gobang" will appear on the screen. On it is a
- checkerboard, clocks and buttons. There will be an instruction saying
- "Please enter the name of player-1". The user can do two things:
- either enter the name of a player or choose the "import" button. Once
- the "import" button is selected, an unfinished game, which was saved
- in the file "###go.bhs###" will be imported. Please notice that the
- character "@" is reserved for the robot player, so if the user types
- in @ as the name of the first player, it is assumed that player-1 is
- the robot player. Then the name of player 2 is prompted. The game
- starts and at each turn an instruction like "Please enter your play."
- would appear on the screen. The user should put a unit onto the
- checkerboard. If the button is clicked on a wrong place or a unit is
- put onto an occupied position, an error message saying "Wrong Point.
- Please reenter." will appear on the screen and the user should reenter
- his play. The marker next to the name of a player indicates whose
- turn it is. At any point of the game the user can choose the other
- four buttons. If the "new" button is selected, the present game will
- be terminated and a new blank checkerboard will be displayed on the
- screen; if the "review" button is selected, one step of the previous
- plays will be displayed each time after the user hits any key; if the
- "save" button is selected, the steps so far will be saved into the
- file "###go.bhs###"; if the "quit" button is selected, the game will
- be terminated.
