【问题描述】:
我做了一个非常基本的乒乓球游戏,但是当球落到底部时,我只设置了一切都停止移动。有没有办法在画布中创建一个按钮,例如“再次播放”,当我点击它时,游戏又开始了。我还需要一个开始游戏的按钮。
我尝试创建一个按钮以在球击中画布底部时弹出,但这没有奏效。我查了一下,找不到任何可以回答我问题的内容。
from tkinter import*
import random
import time
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, 200, 300)
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("Game")
tk.resizable(0,0)
tk.wm_attributes("-topmost",1)
canvas = Canvas(tk,width=500,height=400, 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)
我不知道如何在画布中插入按钮(以重置游戏)。任何人都可以帮忙吗?
谢谢。
