在 Pygame 库中，我正在尝试编写游戏。在游戏中，如果您与目标矩形相撞，您将进入一个新的关卡。一切正常，但是当您与目标矩形发生碰撞时，它会在旧关卡之上绘制新关卡。我希望它清除屏幕，然后绘制关卡。我该怎么做？这是我的代码：

gravity = True

        self.level = 1
    def move(self, dx, dy):
        if dx != 0:
            self.move2(dx, 0)
        if dy != 0:
            self.move2(0, dy)
    def move2(self, dx, dy):
        self.rect.x += dx
        self.rect.y += dy
        for wall in walls:
            if self.rect.colliderect(wall.rect):
                if dx > 0:
                    self.rect.right = wall.rect.left
                if dx < 0:
                    self.rect.left = wall.rect.right
                if dy > 0:
                    self.rect.bottom = wall.rect.top
                if dy < 0:
                        self.rect.top = wall.rect.bottom
