Noughts and Crosses Tkinter 项目

Question

好吧，基本上我的导师已经为我设置了一项任务，即创建一个基于 GUI 的 Noughts and Crosses 不使用类的 Python 游戏，到目前为止，这就是我想出的。我的一个问题是我怎样才能做到这一点，所以每回合它都会将玩家切换到“X”，然后切换到下一个“O”，这样他们就可以轮流了，我尝试了很多方法，但我需要帮助哈哈。 谢谢！

代码如下：

player = "O"
from tkinter import *

game = Tk()
game.title("Noughts and Crosses")

game.geometry("")

app = Frame(game)
app.grid()

def tl():
    topLeft.configure(text = player)

def tm():
    topMid.configure(text = player)

def tr():
    topRight.configure(text = player)

def ml():
    midLeft.configure(text = player)

def mm():
    midMid.configure(text = player)

def mr():
    midRight.configure(text = player)

def bl():
    botLeft.configure(text = player)

def bm():
    botMid.configure(text = player)

def br():
    botRight.configure(text = player)

#Top Row
topLeft = Button(app, text = "-", activebackground="red", command=tl)
topLeft.grid(row = 0, column = 0, ipadx=20, ipady=18, padx=10, pady=10)

topMid = Button(app, text = "-", activebackground="red", command=tm)
topMid.grid(row = 0, column = 1, ipadx=20, ipady=18, padx=10, pady=10)

topRight = Button(app, text = "-", activebackground="red", command=tr)
topRight.grid(row = 0, column = 2, ipadx=20, ipady=18, padx=10, pady=10)

#Middle Row
midLeft = Button(app, text = "-", activebackground="red", command=ml)
midLeft.grid(row = 1, column = 0, ipadx=20, ipady=18, padx=10, pady=10)

midMid = Button(app, text = "-", activebackground="red", command=mm)
midMid.grid(row = 1, column = 1, ipadx=20, ipady=18, padx=10, pady=10)

midRight = Button(app, text = "-", activebackground="red", command=mr)
midRight.grid(row = 1, column = 2, ipadx=20, ipady=18, padx=10, pady=10)


#Bottom Row
botLeft = Button(app, text = "-", activebackground="red", command=bl)
botLeft.grid(row = 2, column = 0, ipadx=20, ipady=18, padx=10, pady=10)

botMid = Button(app, text = "-", activebackground="red", command=bm)
botMid.grid(row = 2, column = 1, ipadx=20, ipady=18, padx=10, pady=10)

botRight = Button(app, text = "-", activebackground="red", command=br)
botRight.grid(row = 2, column = 2, ipadx=20, ipady=18, padx=10, pady=10)

game.mainloop()

Answer 1

创建函数来更改player。当您使用= 时，您必须使用关键字global 来通知函数您使用外部/全局变量。如果没有global，它将创建局部变量，并且不会更改外部player

def change_player():
    global player

    if player == 'O':
        player = 'X'
    else:
        player = 'O'

然后在你的所有函数中使用这个函数 - 像这样：

def tl():
    topLeft.configure(text = player)
    change_player()

---

顺便说一句：为了使代码更具可读性，请将import 放在开头，并将所有函数放在game = Tk() 之前。

您可以使用for 循环来创建所有按钮并将它们保留在linst button[0]、button[1] 等上。然后您可以只创建一个可以分配给所有Button 的函数。 （但它需要lambda 来分配带有参数的函数）

x_turn = 真

虽然不是游戏结束： turn = 'X' if x_turn else 'O'

# Your one-move code goes here

# At the bottom of the loop:
x_turn = not x_turn
