Python图像处理——人物拼图游戏

开发工具：pycharm

游戏介绍：拼图游戏将一幅图片分割咸若干拼块并将它们随机打乱顺序，当将所有拼块都放回原位置时，就完成了拼图（游戏结束）。本人物拼图游戏为3行3列，拼块以随机顺序排列，玩家用鼠标单击空白块四周的交换它们位置，直到所有拼块都回到原位置。拼图游戏运行界面

程序设计思路：

游戏程序首先将图片分割成相应3行3列的拼块，并按顺序编号。动态地生成一个＼为3x3的列表board，用于存放数字0一8，其中，每个数字代表一个拼块，8号拼块不显示。

游戏开始时，随机打乱这个数组board，如board[0l[0]是5号拼块，则在左上角显示编号是5的拼块。根据玩家用鼠标单击的拼块和空白块所在位置，来交换该board数组对应的元素，最后通过元素排列顺序来判断是否已经完成游戏。

游戏逻辑的实现：

1．定义常量及加载图片

2．图像块（拼块）类

3 . 初始化游戏

4 . 绘制游戏界面的各个元素

5 . 鼠标事件

6．判断输赢

7．重置游戏

8．“重新开始”按钮的单击事件

一. 定义常量及加载图片

for i in range(9):
    filename='ka'+str(i)+'.png'
    Pics.append(PhotoImage(file=filename))

二. 图像块（拼块）类

class Square:
    def __init__(self,orderID):
        self.orderID=orderID
    def draw(self,canvas,board_pos):
        img=Pics[self.orderID]
        canvas.create_image(board_pos,image=img)

三. 初始化游戏

board=[[0,1,2],[3,4,5],[6,7,8]]

def init_board():
    L=list(range(8))
    L.append(None)
    random.shuffle(L)
    for i in range(ROWS):
        for j in range(COLS):
            idx=i*ROWS+j
            orderID=L[idx]
            if orderID is None:
                board[i][j]=None
            else:
                board[i][j]=Square(orderID)

四. 绘制游戏界面的各个元素

def drawBoard(canvas):
    canvas.create_polygon((0,0,WIDTH,0,WIDTH,HEIGHT,0,HEIGHT),width=1,outline='Black',fill='green')
    for i in range(ROWS):
        for j in range(COLS):
            if board[i][j] is not None:
                board[i][j].draw(canvas,(IMAGE_WIDTH*(j+0.5),IMAGE_HEIGHT*(i+0.5)))

五. 鼠标事件

def mouseclick(pos):
    global steps
    r=int(pos.y//IMAGE_HEIGHT)
    c=int(pos.x//IMAGE_WIDTH)
    print(r,c)
    if r<3 and c<3:
        if board[r][c] is None:
            return
        else:
            current_square=board[r][c]
            if r-1>=0 and board[r-1][c] is None:
                board[r][c]=None
                board[r-1][c]=current_square
                steps+=1
            elif c+1<=2 and board[r][c+1] is None:
                board[r][c]=None
                board[r][c+1]=current_square
                steps+=1
            elif r+1<=2 and board[r+1][c] is None:
                board[r][c]=None
                board[r+1][c]=current_square
                steps+=1
            elif c-1>=0 and board[r][c-1] is None:
                board[r][c]=None
                board[r][c-1]=current_square
                steps+=1
            Label1["text"]=str(steps)
            cv.delete('all')
            drawBoard(cv)

六判断输赢

def win():
    for i in range(ROWS):
        for j in range(COLS):
            if board[i][j] is not None and board[i][j].orderID!=i*ROWS+j:
                return False

七 . 重置游戏

def callBack2():
    print("重新开始")
    play_game()
    cv.delete('all')
    drawBoard(cv)

八 . 重新开始”按钮的单击事件

cv=Canvas(root,bg='white',width=WIDTH,height=HEIGHT)
b1=Button(root,text="重新开始",command=callBack2,width=20)
Label1=Label(root,text="0",fg='red',width=20)
Label1.pack()
cv.bind('<Button-1>',mouseclick)

from tkinter.messagebox import *
import random

root=Tk('拼图游戏')
root.title("拼图")
