Creating Connect 3 Game with LISP
Explore the world of game development with our step-by-step guide on how to create a Connect 3 game using LISP. This comprehensive tutorial equips you with the knowledge to build the game from scratch, understand LISP programming concepts, and enhance your coding skills. Whether you're a novice or seeking help with your LISP assignment, this guide empowers you to create and innovate within the realm of game development.
Getting Started
Before diving into the code, it's important to have a basic understanding of the LISP programming language.
The Connect 3 Game Implementation
We'll break down the implementation into distinct sections, explaining each block of code:
Step 1: Defining the Game Board
In this step, we define the game board using a 2D list. Each cell in the list represents a spot on the game grid. The values `0`, `1`, and `2` are used to indicate empty cells, player 1's discs, and player 2's discs, respectively.
```lisp
(defvar *board* '(
(0 0 0)
(0 0 0)
(0 0 0)
))
```
Step 2:
Displaying the Game Board The `display-board` function visually represents the current state of the game board. It iterates through the rows and columns of the board and prints dots (`.`) for empty cells and pound signs (`#`) for player discs.
```lisp
(defun display-board ()
(format t " 1 2 3~%")
(dotimes (row 3)
(format t "~d " (+ row 1))
(dotimes (col 3)
(let ((cell (nth row (nth col *board*))))
(if (= cell 0)
(format t ". ")
(format t "# "))))
(format t "~%")))
```
Step 3:
Checking for a Win The `check-win` function examines rows, columns, and diagonals to determine if a player has achieved a winning sequence of three discs. It returns `t` if a win is detected, otherwise `nil`.
```lisp
(defun check-win (player)
;; Check rows, columns, and diagonals
;; Return t if a win is detected, otherwise nil
)
```
Step 4:
Making a Move The `make-move` function handles a player's move by placing their disc in the specified column. It checks if the column is not full and then updates the board accordingly.
```lisp
(defun make-move (col player)
;; Check if the column is not full
;; Update the board with the player's disc
)
```
Step 5:
Main Game Loop The core of our game lies in the `play-connect-3` function. This function orchestrates the gameplay, allowing players to take turns, make moves, and checks for a win condition. The game loop continues until a player wins or the game is over.
```lisp
(defun play-connect-3 ()
;; Initialize game variables
;; Enter the main game loop
)
```
Step 6:
Starting the Game To begin the Connect 3 game, simply call the `play-connect-3` function. This will kick off the game loop, allowing players to play and enjoy the game.
```lisp
(play-connect-3)
```
