【问题描述】:
所以我有一艘潜艇:
from tkinter import *
HEIGHT = 500
WIDTH = 800
window = Tk()
window.title("Bubble Blaster")
c = Canvas(window, width=WIDTH, height=HEIGHT, bg="darkblue")
c.pack()
ship_id = c.create_polygon(5, 5, 5, 25, 30, 15, fill="red")
ship_id2 = c.create_oval(0, 0, 30, 30, outline="red")
我正在读一本关于如何使潜艇移动的书,这就是它所说的:
def move_ship(event):
if event.keysym == "up":
c.move(ship_id, 0, -ship_spd)
c.move(ship_id2, 0, -ship_spd)
elif event.keysym == "Down":
c.move(ship_id, 0, ship_spd)
c.move(ship_id2, 0, ship_spd)
elif event.keysym == "Left":
c.move(ship_id, -ship_spd, 0)
c.move(ship_id2, -ship_spd, 0)
elif event.keysym == "Right":
c.move(ship_id, ship_spd, 0)
c.move(ship_id2, ship_spd, 0)
c.bind_all('<key', move_ship)
当我运行它时,它给了我一个错误:
PS.我在 sn-p 中这样做是因为 Ctrl+v 不会完成所有消息
<h4 style="color: red">Traceback (most recent call last):
File "C:\Users\Bloxy Craft\Desktop\Bubble Blaster.py", line 28, in <module>

谢谢!

顺便说一下这本书的名字,帮助您的孩子进行计算机编码
-
<key>与<Key>不同。您需要使用<Key>
