如何在pygame中获取像素的颜色值？

Question

I want to get the color value of a pixel. I have read something about a function called "pygame.Surface.get_at()". But when I use this function i get this error:

Traceback (most recent call last):
pygame.Surface.get_at(300, 200)
TypeError: descriptor 'get_at' requires a 'pygame.Surface' object but received a 'int'

Answer 1

You have two problems here:

• get_at requires a tuple (x, y) so you should invoke it with:

   .get_at((300, 200)) 

• You should provide the surface for which you want to get the pixel color. Something like this:

   screen = pygame.display.set_mode((150, 50)) ... screen.get_at((300, 200))
