python - 文本框没有出现在我的游戏 Tic Tac Toe python 中

Question

我制作了一款名为 Tic Tac Toe 的游戏，这是一款 2 人游戏，当你让他们连续或对角地获得 3 个 X 或 3 个 O 时。

代码:

from guizero import *

empty = '  '
player = "X"

def clicked(z):
    button = buttonlist[int(z)] # Finds out which button was pressed
    global empty, player
    if button.text != empty:
        pass # If button already pushed do nothing
    else:
        # Marks button with user's go
        button.text = player
        # Switches players
        if player == "X":
            player = "O"
        else:
            player = "X"
    return

app = App(title="Tic Tac Toe", layout="grid", width=200, height=200)
buttonlist = [] # Empty list to contain a list of Buttons

text_box = TextBox(app, text="enter username", align="top")

# Create Buttons for game, in 3 rows of 3
for y in range(3):
    for x in range(3):
        z = (3*y) + x
        buttonlist.append(PushButton(app, text=empty, 
                          args=str(z), grid=[y, x], command=clicked))

app.display()

我遇到的问题是当我输入行时:

text_box = TextBox(app, text="enter username", align="top")

游戏仍然打开，但我收到一条错误消息:

*** GUIZERO WARNING ***
[TextBox] object with text "enter username" will not be displayed because it has a missing grid reference.

有人可以帮我解决这个问题吗。

文档说在使用网格布局时需要传递网格位置: https://lawsie.github.io/guizero/layout/#grid-layout

这是您可以传递的参数的示例:

# this will display the textbox after the buttons
text_box = TextBox(app, text="enter username", align="top",grid=[0,4,3,1])
#  0 : column position (x)
#  4 : row position    (y)
#  3 : span 3 columns  (x span)
#  1 : span 1 row      (y span)

如果你想在顶部显示2个文本框，你可以移动循环中的所有位置:

text_box = TextBox(app, text="enter username", align="top", grid=[0, 0, 3, 1])
text_box2 = TextBox(app, text="enter username2", align="top", grid=[0, 1, 3, 1])

z=0
for x in range(3):
    for y in range(2, 5):
        buttonlist.append(PushButton(app, text=empty, args=str(z), grid=[x, y], command=clicked))
        z+=1

app.display()
