I am horribly (obssesed?) with writing a visually appealing game (simple) in python. My text adventures didn't appeal to my aufience (family), so I was looking at a tut on making a pac man clone, supposed to be line by line, it seemes choppy. Any ways, here is the code.
#! /usr/bin/env python
import os, sys

from pygame.locals import *
from helpers import *

"""The Main PyMan Class - This class handles the main
initialization and creating of the Game."""
def __init__(self, width=640,height=480):
"""Initialize"""
"""Initialize PyGame"""
pygame.init()
"""Set the window Size"""
self.width = width
self.height = height
"""Create the Screen"""
self.screen = pygame.display.set_mode((self.width
, self.height))
def MainLoop(self):
"""This is the Main Loop of the Game"""
"""Load All of our Sprites"""
self.LoadSprites();
"""tell pygame to keep sending up keystrokes when they are
held down"""
pygame.key.set_repeat(500, 30)
"""Create the background"""
self.background = pygame.Surface(self.screen.get_size())
self.background = self.background.convert()
self.background.fill((0,0,0))
while 1:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
elif event.type == KEYDOWN:
if ((event.key == K_RIGHT)
or (event.key == K_LEFT)

class Snake(pygame.sprite.Sprite):

if __name__ == "__main__":
MainWindow = PyManMain()
MainWindow.MainLoop()Anyways, how do I change the sprites used? I see the self.loadSprites function, so I was wondering, how do I edit the sprites this function loads? If neccessary, I will give info on the directories they are placed in.
Also, what should I learn/read to better make (also, easy up the development process) these games. I want to make a rpg pacman clone. Not sure exactly what that means, I guess, pick up weapons, hit points, etx (unles hitpoints are too intermediate I could just have lives).
I want to have more than the black maze backround also. Any ideas/suggestions on how to make this game would be appreciated.
Also, where could I find the most in depth tut on making a first game in python?
