我目前正在做一个乒乓球游戏,但我想在游戏的左上角添加一个重置按钮,使用tkinter。我对这一点很陌生,所以请尽量用简单的语言解释。我试着添加一个按钮,但不知道如何让它重置程序。提前谢谢你。这是我的代码:
from tkinter import *
import random
import time
import pygame
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 = 3
if pos[3] >= self.canvas_height:
self.hit_bottom = True
if self.hit_paddle(pos) == True:
self.y = -3
if pos[0] <= 0:
self.x = 3
if pos[2] >= self.canvas_width:
self.x = -3
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, 450, 750)
self.x = 0
self.canvas_width = self.canvas.winfo_width()
self.canvas.bind_all('<KeyPress-Left>', self.turn_left)
self.canvas.bind_all('<KeyPress-Right>', self.turn_right)
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 = -3
def turn_right(self, evt):
self.x = 3
tk = Tk()
tk.title("Pong Game")
tk.resizable(0, 0)
tk.wm_attributes("-topmost", 1)
canvas = Canvas(tk, width=1000, height=800, 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)
一种方法是使用代码再次运行程序。在
将这一行添加到按钮事件所在的位置:
exec(open("./your_file.py").read())
。在本质上,程序实际上是在告诉自己运行自己。在

答案,但是,我更希望重新排列如下所示的代码,并简单地重新创建浆和球实例。在相关问题 更多 >
