我正在尝试做一个小游戏。但我有一个问题。我想要做的是，每次我按下空格键时，它都会将 1 添加到“score”变量中。为此，我正在使用海龟模块（mouse.onkeypress(Space, "space"）的“onkeypress”功能据我所知，每次按下空格键时都应该运行“Space”功能。它适用于我制作的所有其他项目，但这一次，它没有，我不知道为什么..我尝试使用“onkey”而不是“onkeypress”，也不起作用..

那么，如果有人有想法？

这是代码：（函数在它的末尾）


setup = turtle.Turtle()
mouse = turtle.Screen()
up_score = turtle.Turtle()

score = 0
x = 5
sc_per_se = 0

E1 = 10
E2 = 10
E3 = 10
E4 = 10
E5 = 10

up_score.hideturtle()
up_score.penup()
up_score.speed(0)
setup.penup()
setup.speed(0)

up_score.goto(-300, -300)
up_score.write(score)

setup.right(90)

声明mouse.listen应该是。mouse.listen()

此外，当我尝试运行您的代码时，它失败了，抱怨说global似乎被冗余使用的语句以及在不应该使用的地方。以下是我对您的代码的修改，以解决这些问题和其他问题：

from turtle import Screen, Turtle

score = 0
sc_per_se = 0

E1 = 10
E2 = 10
E3 = 10
E4 = 10
E5 = 10

def whereClick(x, y):
    global sc_per_se
    global E1, E2, E3, E4, E5

    if -300 <= x <= -255 and 300 <= y <= 312:
        if E1 < 210:
            print("Element 1 upgraded!")
            setup.goto(E1 - 255, 302)
            setup.pendown()
            setup.forward(10)
            setup.penup()
            E1 += 10
            sc_per_se += 0.001
        else:
            print("Max upgrade level reached!")

    if -300 <= x <= -255 and 250 <= y <= 262:
        if E2 < 210:
            print("Element 2 upgraded!")
            setup.goto(E2 - 255, 252)
            setup.pendown()
            setup.forward(10)
            setup.penup()
