可能有2幅画布

Question

所以我对精灵的控制工作，直到我添加了一个随机移动精灵的代码。这是代码：

    self.shape = self.canvas.create_oval(0,0,50,50,fill="grey80")
    self.speedx = (10)
    self.speedy = (10)

    self.enemy1_list = []
    for i in range(1):
        self.enemy1_list.append(self.playWindow())
    while True:
        for self.playWindow in self.enemy1_list:
            self.playWindow.update()
        parent.update()
        time.sleep(0.01)

def update(self):
    if pos[2] >= WIDTH or pos[0] <= 0:
        self.speedx *= -0.5
    if pos[3] >= HEIGHT or pos[1] <= 0:
        self.speedy *= -0.5

我收到此错误代码：

AttributeError: 'playWindow' object has no attribute 'playWindow'
