仅评分一次更新一次，并且根本不更新

Question

当我的布朗尼（按下W时移动）时，我在保持分数时遇到麻烦。现在，它使得分数翻了一番，但每次按W之后按2分保持2分。

这是剧本：

import turtle

wn = turtle.Screen()
wn.setup(2000, 1000)
wn.bgcolor("black")

brnw = turtle.Turtle()
brnw.goto(-500, 100)
brnw.penup()
brnw.shape("square")
brnw.shapesize(5, 10)
brnw.color("#8A360F")

point_giver = turtle.Turtle()
point_giver.penup()
point_giver.color("#8A360F")
point_giver.goto(-500,100)

points = 1



def Brnw_Animation():
    points =+ 1
    brnw.speed(3)
    brnw.goto(-500, 0)
    brnw.goto(-500, 100)
    if brnw.pos()[1] >= point_giver.pos()[1]:
        score = turtle.Turtle()
        score.penup()
        score.goto(0, 0)
        score.color("green")
        score.write(points, font=('arial', 14, 'bold'))



pressed = wn.onkeypress(Brnw_Animation, 'w')
wn.listen()

while True:
    wn.update()

 

Answer 1

它看起来像一个简单的错字：points = + 1应该是点 + = 1
