Question

所以这是我的一款名为Zombie Dice的游戏。

我已经导入了图片，但是我收到了这个错误，我不明白为什么。请为我解释一些可能性。

"File "<pyshell#0>", line 1, in <module>
    Game()
  File "C:\Users\Brandon\Desktop\FinalProject3.py", line 17, in Game
    Yellow = DieViewYellow(Gamewindow, Point(95,75),20)
  File "C:\Users\Brandon\Desktop\DieViewYellow.py", line 83, in __init__
    p1 = Point(x-25, y-25)
NameError: name 'Point' is not defined">

这是我的Die视图类，即使导入图形也会给我一个问题

#Die View Yellow
from graphics import *

class DieViewYellow:

def __init__(self, win, center, value):
    """Create a view of a die, e.g.:
       d1 = GDie(myWin, Point(40,50), 20)
    creates a die centered at (40,50) having sides
    of length 20."""

    # first define some standard values
    self.win = win
    #self.background = Color # color of die face
    #self.foreground = Color2 # color of the pips

你没有显示所有代码，但我相信你有这样的东西作为你的import语句：

import graphics

或

from module import graphics

您正在尝试使用Point类：

p2 = Point(x+25, y+25) # This fails.

但是Python并不知道Point模块中存在graphics。无论何时使用Point：

，您都需要告诉它

p2 = graphics.Point(x+25, y+25) # This works fine!

如果您想在没有Point前缀的情况下使用graphics，可以直接从graphics.导入from graphics import Point p2 = Point(x+25, y+25) # This works fine now!。

问题已被编辑，所以这个答案现在有点多余。我会留下它。

即使我导入了图形，也没有定义点
