python，turtle，“onkeypress”不起作用

Question

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，我使用了 turtle 模块的“onkeypress”功能（mouse.onkeypress(Space, "space"） 据我所知，每次按空格键时，它都应该运行“空格”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..

如果有人有想法？

代码如下：（函数在最后）

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)
setup.goto(-300, 300)

for a in range(5):
    setup.write("[Upgrade]")
    setup.forward(50)

setup.right(90)
setup.forward(75)
setup.right(90)

for a in range(5):
    global x
    setup.forward(50)
    setup.write("Element")
    setup.right(90)
    setup.forward(40)
    setup.write(x)
    setup.left(180)
    setup.forward(40)
    setup.right(90)
    x -= 1

setup.hideturtle()

def whereClick(x, y):
    #print("x=", int(x) ,"/","y=", int(y))

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

    up_score.undo()
    up_score.write(int(score))

    score += sc_per_se

turtle.done()

Answer 1

mouse.listen 语句应该是 mouse.listen()。

另外，当我尝试运行您的代码时，它因抱怨global 语句而失败，这些语句似乎被冗余使用并且在不应该使用的地方使用。以下是我为解决这些问题和其他问题而对您的代码进行的修改：

from turtle import Screen, Turtle

sc_per_se = 0

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.penup()
