TypeError: Argument must be rect style object
我不明白为什么Python会返回此错误。如果在语法的上下文中分析，则行144是正确的。这个论点似乎是格式正确的。代码结构中是否有任何错误，可能是第144行与其他行之间的交互？
答案 0 :(得分：1)
pygame.draw.rect(surf,self.color,pygame.Rect(self.posx,self.posy,self.width,self.height),0)
这一定是;
pygame.draw.rect(surf,self.color,(self.posx,self.posy,self.width,self.height),0)
您正在尝试将rectstyle对象放入rect coords中。有效语法是;
a= where you want to draw your rect, it's a surface object,screen
b= RGB color of rect
c=coordinates in a tuple
pygame.draw.rect(a,b,c)
c=coordinates in a tuple实际上意味着，
(x,y,wx,hy)
x= x coordinate of your rectangle
y= y corrdinate of your rectangle
wx= the lenght of x coord of your rectangle. If `x` is bigger,your rectangle is bigger.
hx= the height of y coord of your rectangle. If `y` is bigger, your rectangle is bigger.
