Is there an attribute called rect.center in pygame?

Question

I was looking through a pygame tutorial and encountered the following part of a script:

fontObj = pygame.font.Font('freesansbold.ttf', 32)
textSurfaceObj = fontObj.render('hellow world', True, Green, Blue)
textRectObj = textSurfaceObj.get_rect()
textRectObj.center = (200,150)

The last line set the center of the rect at (200.150) I looked through the pygame documentation and there is no center attribute in the Rect class. But the script works... why ?

Answer 1

根据docs on rect：

  

Rect对象有几个虚拟属性，可用于移动和对齐Rect：

     

的x，y

     

顶部，左侧，底部，右侧

     

topleft，bottomleft，topright，bottomright

     

midtop，midleft，midbottom，midright

     

中心，centerx，centery

     

尺寸，宽度，高度

     

W，H

我加粗center。
