如何让 Turtle 等待按下的键

我和我的团队创建了一款在 Turtle 上运行的棋盘游戏。我们很难在不需要 IDE 控制台的情况下运行游戏。 我们希望使用 onkeypress 来运行我们的游戏，这样用户就不必离开游戏窗口。

问题出在 while 循环中，需要输入才能运行代码。

input("Press enter to roll the dice: ")

我们很难找到输入的替代品。

这并不完美，但您可以使用textinput()Python3 Turtle 中的函数来实现这一点。一个极简的例子：

from turtle import Screen

screen = Screen()

while True:
    answer = screen.textinput("Next Game", "Press OK to roll the dice, Cancel to quit:")

    if answer is None:
        break
