Re: [pygame] Storing images in a list

Jake,

The image loads here...

def game_image (image_file):
    image = pygame.image.load (image_file).convert_alpha ()
    return image

The image is assigned like...

red_stone = game_image ("red_stone.png")

Later, it goes into the list like...

board_layout.append ([red_stone, (x, y)...])

So is a copy of red_stone in the list or just a pointer?

When an element of the list says <Surface 50x50x32>, is that pointing to a
spot in the memory or is the actual image being stored in that index?

That's a surface. You can have multiple variables point to the same surface.


Would I have 64 images in my list if every space is occupied or would I have just
2 images in memory?

I can't be sure without seeing your init/draw code, but it sounds like
you probably have 64.

Are you doing something like this?

def init():
	"""game init"""
	red = pygame.Surface( [10, 10] )
	red.fill( pygame.color.Color( "red" ) )
	blue = pygame.Surface( [10, 10] )
	blue.fill( pygame.color.Color( "blue" ) )
	# init tiles with color red
	for tile in tile_list:
		# sharing one surface for tiles
		tile.image = red

def draw():
	"""game draw"""
	for tile in tile_list:
		# draw using tile.image
