Questions tagged [pygame-surface]

pygame object for representing images. Use this tag only if you are using the pygame library and not if you have a question about programming a game in python in general.

The most important part of pygame is the surface. Just think of a surface as a blank piece of paper. You can do a lot of things with a surface – you can draw lines on it, fill parts of it with color, copy images to and from it, and set or read individual pixel colors on it. A surface can be any size (within reason) and you can have as many of them as you like (again, within reason). One surface is special – the one you create with pygame.display.set_mode(). This ‘display surface’ represents the screen; whatever you do to it will appear on the user’s screen. You can only have one of these – that’s an SDL limitation, not a pygame one.
