'pygame.Surface' 对象没有属性 'color'

Question

所以，我的问题是我正在尝试绘制一个矩形，但我一直收到错误提示 'pygame.Surface' object has no attribute 'color'。有人可以帮助我吗？

完整错误消息

遵循 Python 禅 显式优于隐式。

Often, the first argument of a method is called self. This is nothing more than a convention: the name self has absolutely no special meaning to Python. Note, however, that by not following the convention your code may be less readable to other Python programmers, and it is also conceivable that a class browser program might be written that relies upon such a convention.

这意味着你应该将第一个参数设置为self，而且你忘记了一个comma，代码应该是这样的：

def draw(self,screen):
    pygame.draw.rect(screen, self.color,(self.x, self.y, self.w, self.h))
