有人可以帮忙吗?
我有两个名为game.py
和settings.py
的文件,我只想从游戏中使用的设置中获取一个值,但我不知道我做错了什么。
我希望它的值在函数bbbbb ...
中THIS IS MY SETTINGS
from tkinter import*
import game
class Application(Frame):
def __init__ (self, master):
Frame.__init__(self,master)
self.grid()
self.create_widgets()
def bbbbb(self):
self.xr = self.ball_numbers.get()
print("printing...", self.xr)
return self.xr
def create_widgets(self):
self.ball_numbers = IntVar()
Label(self,text = "Select how many balls you wish to play:").grid()
Radiobutton(self, text = "1 Ball", variable = self.ball_numbers, value = 1, command = self.bbbbb).grid ()
Radiobutton(self, text = "2 Balls", variable = self.ball_numbers, value = 2, command = self.bbbbb).grid ()
Radiobutton(self, text = "3 Balls", variable = self.ball_numbers, value = 3, command = self.bbbbb).grid ()
settings_window = Tk()
settings_window.title(" THE BOUNCER - Settings")
settings_window.geometry("600x600")
app = Application(settings_window)
settings_window.mainloop()
我在 create_ball_numbers
函数中需要 handling_settings 类中的值这是我的game.py
from livewires import games, color
from tkinter import*
import settings
import random
games.init(screen_width = 735, screen_height = 350, fps = 35)
class Bounce(games.Sprite):
def update(self):
if self.right > games.screen.width or self.left < 0:
self.dx = -self.dx
if self.top < 0:
self.dy = -self.dy
if self.bottom == 315 and self.overlapping_sprites:
self.dy = -self.dy
class Bar_moving(games.Sprite):
def update(self):
self.x = games.mouse.x
self.y = 315
class handling_settings():
self.yr = bbbbb()
print("printing number from settings ", self.yr)
def create_ball_numbers(self):
print("inside def", self.yr)
def main():
background = games.load_image("BG.jpg", transparent = False)
games.screen.background = background
call = handling_settings()
call.create_ball_numbers()
bar_small = games.load_image("bar_small.jpg", transparent = False)
the_bar_small = Bar_moving(image = bar_small, x = games.mouse.x)
games.screen.add(the_bar_small)
games.mouse.is_visible = False
games.screen.event_grab = True
games.screen.mainloop()
main()
I think I am not using on the right way IMPORT on top of the file.... keeping appearing this msg...
File "C:\Users\Bruno\Desktop\DIT\Object Oriented Programming\GAME - Assignment\game.py", line 3, in <module>
from settings import bbbbb
ImportError: cannot import name bbbbb
如果我单独运行这两个文件......可以......但是当我尝试在bbbbb
中的settings
函数中获取值时,我会卡住...
答案 0 :(得分:1)
你有一个循环导入; settings
导入game
,导入settings
。那时,两个模块都没有完全初始化(超出import
行的任何东西还没有运行)。
您实际上使用 game
中的settings
模块,因此只需从import game
移除settings.py
行。< / p>
在game.py
中,您导入了settings
名称; bbbbb
是该模块中 Application
类的属性。这一行:
self.yr = bbbbb()
永远不会在这里工作。
然而,您绝对应该 在Tk()
中创建新的settings
根窗口;你只能在Tk应用程序中拥有一个主循环。使settings
成为game
中主应用程序触发的对话窗口。
因此,要获得bbbbb()
结果,您需要生成设置对话框,让用户与其进行交互,然后在用户再次关闭对话框时检索ball_numbers
设置。 / p>

首先不要在settings.py中进行任何循环导入,不需要导入游戏模块。
由于bbbbb是类Application的函数,因此无法直接调用它,为了调用它我们需要一个同一个类的对象,它已经被创建为
app = Application(settings_window)
所以,在模块game.py中,只需使用app对象来调用bbbbb()
self.yr = settings.app.bbbbb()
