python简单游戏-反弹球，供大家参考，具体内容如下
tkinter实现，直接贴上代码
from tkinter import*
import time
import random
class 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 = -4
class 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：
