python编写弹球游戏的实现代码

#coding:utf-
from tkinter import *
import random
import time
 
class Ball:
    #创建一个球类
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(, , , , fill=color)
        #返回刚好划小球的id，create_oval创建一个椭圆
        self.canvas.move(self.id, , )
        #把椭圆移动到画布
        starts = [-, -, -, , , ]
        random.shuffle(starts)
        #随机排列
        self.x = starts[]
        self.y = -
        self.canvas_height = self.canvas.winfo_height()
        #获取画布当前高度
        self.canvas_width = self.canvas.winfo_width()
        #获取画布当前宽度
    def draw(self):
        self.canvas.move(self.id, self.x, self.y)
        #让小球水平和垂直移动
        pos = self.canvas.coords(self.id)
        #coords返回画布上画好的x和y坐标
 
        #判断小球是否撞到画布顶部或者底部，保证小球反弹回去，不消失
        if pos[] <= :
            self.y =
        if pos[] >= self.canvas_height:
            self.y = -
        if pos[] <= :
            self.x =
        if pos[] >= self.canvas_width:
            self.x = -
 
tk = Tk()
tk.title("Game")
 
tk.resizable(, )
#窗口大小不可调整
tk.wm_attributes("-topmost", )
#使画布窗口置于所有窗口之前
canvas = Canvas(tk,width=, height=, bd=, highlightthickness=)
#bd和highlighttthickness是为了保证画布没有边框
canvas.pack()
tk.update()
#动画初始化
 
ballone = Ball(canvas, 'red')
balltwo = Ball(canvas, 'blue')
 
while :
    #画布一出现会马上消失，为了防止画布消失，用tkinter一直重画
    ballone.draw()
    balltwo.draw()
    tk.update_idletasks()
    tk.update()
    time.sleep(0.01)
