我正在尝试创建这个"Ball“类，我想让它在撞到墙上时反弹，但它仍然被挡在角落里。

class Ball:
    def __init__(self, x, y, radius, speed):
        self.x = x
        self.y = y
        self.radius = radius
        self.speed = speed

    def move(self):
        self.x += self.speed[0]
        self.y += self.speed[1]

    def check_collision(self, wall):
        if self.x - self.radius <= wall.x or self.x + self.radius >= wall.x + wall.width:
            self.speed[0] *= -1
        if self.y - self.radius <= wall.y or self.y + self.radius >= wall.y + wall.height:
            self.speed[1] *= -1

class Wall:
    def __init__(self, x, y, width, height):
        self.x = x
        self.y = y
        self.width = width
        self.height = height

# 创建球和墙的实例
ball = Ball(50, 50, 10, [1, 1])
wall = Wall(0, 0, 100, 100)

# 模拟球的运动和碰撞检测
for _ in range(100):
    ball.move()
    ball.check_collision(wall)
    print(ball.x, ball.y)
