Maps that use tilesets, like super nintendo/nes RPG's store the tile ID number for each tile. Map is a 2d array of ID's. This takes almost no memory, since if you have 100 tiles, with 2 types of tiles, you end up with 2 images loaded. vs redundant Sprites on every square.
source_x = tile_width * ID source_rect = Rect( source_x, 0, tile_width, tile_height ) The pinman tutorials use tiles as well, just not in a grid. At game start, it creates a rectangle filled Sprite using Color. Then in the loop, it draws the pre-rendered surface. This is because re-creating a new surface, every loop, is slow. It has some SpriteGroup examples that can make the other tut easier to read. http://www.sacredchao.net/~piman/writing/sprite-tutorial.shtml And probably overkill for now, but sometime you'll want NumPy. Reading 'quick intro' section is enough. Good page for a quickref to numpy. http://www.scipy.org/Tentative_NumPy_Tutorial On Tue, May 18, 2010 at 8:12 PM, Alex Hall <mehg...@gmail.com> wrote: > Okay, so to sprite or not to sprite...
