迭代函数

Question

如何迭代类中的函数定义？

class Big:
    def __init__(self):
        self.win = GraphWin("Bounce", 500, 500)
        self.win.setCoords(-10, -10, 10, 10)
        #self.win.getMouse()

    def close(self):
        self.win.getMouse()

    def ball(self):
        x = 1
        y = 1
        #self.win = win
        circ = Circle(Point(x, y), 0.25)
        circ.draw(self.win)

    def move(self):
        movement = [0.5, 0.3]
        x += movement[0]
        y += movement[1]

我想在函数move中更改x和y的值。 我怎样才能做到这一点？然后再次创建对象Circle

Answer 1

在python中，您必须像在self.win中那样在 init 中声明私有成员。

尝试在其中添加self.x = 0并使用self.x随处访问

Answer 2

class Ball:
   def __init__(self,x,y,rad):
       self.root = root
       self.x = x
       self.y = y
   def draw(self,target):
       Circle(Point(X,y),rad).draw(target)

然后只是使用..

class Big:

    def __init__(self):
        self.win = GraphWin("Bounce", 500, 500)
        self.win.setCoords(-10, -10, 10, 10)
        self.ball = Ball(1,1,0.25)
        #self.win.getMouse()

    def close(self):
        self.win.getMouse()

    def draw(self):
        self.ball.draw(self.win)

    def move(self):
        movement = [0.5, 0.3]
        self.ball.x += movement[0]
        self.ball.y += movement[1]
