Pygame Image position

Question

I\'ve recentley started using pygame to see what I could come up with and come across a problem which I can\'t find an answer to without this pygame.sprite.Sprite and rect t

Answer 1

You can use .get_rect() for image to get image rectangle (pygame.Rect())

space_ship = pygame.image.load(spaceship).convert_alpha()

space_ship_rect = space_ship.get_rect()

and than you can get x, y, width, height and even centerx, centery, center etc.

print space_ship_rect.x, space_ship_rect.y, 
print space_ship_rect.centerx, space_ship_rect.centery, 
print space_ship_rect.center
print space_ship_rect.left, space_ship_rect.right
print space_ship_rect.top, space_ship_rect.bottom
print space_ship_rect.topleft, space_ship_rect.bottomright
print space_ship_rect.width, space_ship_rect.height

by the way: .get_rect() works also with your screen and other pygame.Surface().

But you can't assign new values to image so you have to keep space_ship_rect and change values in it (so use get_rect() only once to get image size)

space_ship_rect.x = 100
space_ship_rect.y = 200
 # or
space_ship_rect.centerx = 100
space_ship_rect.centery = 200

If you change x, y rectangle recalculate centerx, centery using width and height. If you change centerx, centery rectangle recalculate x and y

You could create class with self.image for bitmap and self.rect for image size and position.

ps. you can use screen.blit(space_ship, space_ship_rect)
