python编写弹球游戏的实现代码

#coding:utf-8
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(10, 10, 25, 25, fill=color)
        #返回刚好划小球的id，create_oval创建一个椭圆
        self.canvas.move(self.id, 245, 100)
        #把椭圆移动到画布
        starts = [-3, -2, -1, 1, 2, 3]
        random.shuffle(starts)
        #随机排列
        self.x = starts[0]
        self.y = -3
        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[1] <= 0:
            self.y = 3
        if pos[3] >= self.canvas_height:
            self.y = -3
        if pos[0] <= 0:
            self.x = 3
        if pos[2] >= self.canvas_
            self.x = -3
 
tk = Tk()
tk.title("Game")
 
tk.resizable(0, 0)
#窗口大小不可调整
tk.wm_attributes("-topmost", 1)
#使画布窗口置于所有窗口之前
canvas = Canvas(tk,width=500, height=400, bd=0, highlightthickness=0)
#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 1:
    #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)

效果
