这篇文章将为大家详细讲解有关python实现简单反弹球游戏的方法，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
具体内容如下
tkinter实现，直接贴上代码
from tkinter import*import timeimport randomclass Ball: def __init__(self,canvas,paddle,color): self.canvas = canvas self.paddle = paddle self.id = canvas.create_oval(10,10,25,25,fill=color) self.canvas.move(self.id,245,100) starts = [-3,-2,-1,1,2,3] random.shuffle(starts) self.x = starts[0] self.y = -3 self.canvas_height = self.canvas.winfo_height() self.canvas_width = self.canvas.winfo_width() self.hit_bottom = False def hit_paddle(self,pos): paddle_pos=self.canvas.coords(self.paddle.id) if pos[2]>=paddle_pos[0] and pos[0]<=paddle_pos[2]: if pos[3]>=paddle_pos[1] and pos[3]<=paddle_pos[3]: return True return False def draw(self): self.canvas.move(self.id,self.x,self.y) pos = self.canvas.coords(self.id) if pos[1] <= 0: self.y = 4 if pos[3] >= self.canvas_height: self.hit_bottom=True if self.hit_paddle(pos)==True: self.y=-4 if pos[0] <= 0: self.x = 4 if pos[2] >= self.canvas_width: self.x = -4class Paddle: def __init__(self,canvas,color): self.canvas = canvas self.id = canvas.create_rectangle(0,0,100,10,fill=color) self.canvas.move(self.id,200,400) self.x=0 self.canvas_width = self.canvas.winfo_width() canvas.bind_all('<KeyPress-Left>',self.turn_left) canvas.bind_all('<KeyPress-Right>',self.turn_right) self.hit_bottom = False def draw(self): self.canvas.move(self.id,self.x,0) pos = self.canvas.coords(self.id) if pos[0] <= 0: self.x = 0 elif pos[2] >= self.canvas_width: self.x = 0 def turn_left(self,evt): self.x=-7 def turn_right(self,evt): self.x=7 tk = Tk()tk.title("反弹吧！球球")#tk.resizable(0,0)tk.wm_attributes("-topmost",1)canvas = Canvas(tk,width=650,height=600,bd=0,highlightthickness=0)canvas.pack()tk.update()paddle=Paddle(canvas,'blue')ball = Ball(canvas,paddle,'red')while 1: if ball.hit_bottom==False: ball.draw() paddle.draw() tk.update_idletasks() tk.update() time.sleep(0.01)效果：
