Detect mouseover an image in Pygame

Question

I have an image:

newGameButton = pygame.image.load("images/newGameButton.png").convert_alpha()

I then display it on the screen:

screen.blit(newGameButton, (0,0))

How do I detect if the mouse is touching the image?

Answer 1

Use Surface.get_rect to get a Rect describing the bounds of your Surface, then use .collidepoint() to check if the mouse cursor is inside this Rect.

Example:

if newGameButton.get_rect().collidepoint(pygame.mouse.get_pos()):
    print "mouse is over 'newGameButton'"
