pygame - How do you select a sprite image from a sprite sheet in Python?

Question

I want to import a sprite sheet and select one sprite. How would I do this in Python/pygame?

Answer 1

The above spritesheet loader is a good method. Based on that code, I made this generalized function that works for any spritesheet:

# Version = '2.0'

import pygame,sys
from pygame.locals import *

def sprite_sheet(size,file,pos=(0,0)):

    #Initial Values
    len_sprt_x,len_sprt_y = size #sprite size
    sprt_rect_x,sprt_rect_y = pos #where to find first sprite on sheet

    sheet = pygame.image.load(file).convert_alpha() #Load the sheet
    sheet_rect = sheet.get_rect()
    sprites = []
    print sheet_rect.height, sheet_rect.width
    for i in range(0,sheet_rect.height-len_sprt_y,size[1]):#rows
        print "row"
        for i in range(0,sheet_rect.width-len_sprt_x,size[0]):#columns
            print "column"
            sheet.set_clip(pygame.Rect(sprt_rect_x, sprt_rect_y, len_sprt_x, len_sprt_y)) #find sprite you want
            sprite = sheet.subsurface(sheet.get_clip()) #grab the sprite you want
            sprites.append(sprite)
            sprt_rect_x += len_sprt_x

        sprt_rect_y += len_sprt_y
        sprt_rect_x = 0
    print sprites
    return sprites

#VERSION HISTORY

    #1.1 - turned code into useable function

    #2.0 - fully functional sprite sheet loader

For reference, this cuts sheets into individual sprites one row at a time from left to right.
