I am working on a game, in which you can create mazes. You place blocks on a 16x16 grid, while choosing from a variety of block to make the level with. Whenever you create a block, it adds this class:
class Block(object):
def __init__(self,x,y,spr):
self.x=x
self.y=y
self.sprite=spr
self.rect=self.sprite.get_rect(x=self.x,y=self.y)
to a list called instances.
I tried shelving it to a .bin file, but it returns some error dealing with surfaces. How can I go about saving and loading levels?
Any help is appreciated! :)
Here is the whole code for reference:
import pygame
from pygame.locals import *
#initstuff
pygame.init()
screen=pygame.display.set_mode((640,480))
pygame.display.set_caption('PiMaze')

b1spr=pygame.image.load('images/b1.png').convert()
b2spr=pygame.image.load('images/b2.png').convert()
currentbspr=b1spr
curspr=pygame.image.load('images/curs.png').convert()
curspr.set_colorkey((0,255,0))
#menu
menuspr.set_alpha(185)
menurect=menuspr.get_rect(x=-260,y=4)
class MenuItem(object):

self.x=pos[0]
self.y=pos[1]
self.sprite=spr
self.pos=(self.x,self.y)
