The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Pygame errror: IndexError: list index out of range

3 posts in this topic

Hello, I was just making a "Stickman" class for the player and I get this error :IndexError: list index out of range

Here is the code:

import pygame, sys, glob
from pygame import *

h=400
w=800

screen = pygame.display.set_mode((w,h))

clock = pygame.time.Clock()

class player:
    def __init__(self):
        self.x = 200
        self.y = 300
        self.ani_speed_init=10
        self.ani_speed=self.ani_speed_init
        self.ani = glob.glob("C:\Users\user\Desktop\Python Programs\Sprite Example\Entities\Stcik_Man_Walk*.png")
        self.ani.sort()
        self.ani_pos=0
        self.ani_max = len(self.ani)-1
        self.img = pygame.image.load(self.ani[0])
        self.update(0)
        
    def update(self, pos):
        if pos != 0:
            self.ani_speed-=1
            self.x+=pos
            if self.ani_speed == 0:
                self.img = pygame.image.load(self.ani[self.ani_pos])
                self.ani_speed = self.ani_speed_init
                if self.ani_pos == self.ani_max:
                    self.ani_pos = 0
                else:
                    self.ani_pos+=1
            screen.blit(self.img,(self.x,self.y))

player1 = player()
pos = 0

while 1:
    screen.fill((255,0,0))
    clock.tick(60)

    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == KEYDOWN and event.key == K_RIGHT:
            pos = 1
        elif event.type == KEYUP and event.key == K_RIGHT:
            pos= 0

    player1.update(pos)

    pygame.display.update()

It looks like you're going over the end of a list, but I really can't understand what your code is doing (no experience with python).

 

From this line, I assume self.ani has only one record (the name of the file).

self.ani = glob.glob("C:\Users\user\Desktop\Python Programs\Sprite Example\Entities\Stcik_Man_Walk*.png")

But here, it looks like you're trying to read other positions from self.ani that currently doesn't exist.

self.img = pygame.image.load(self.ani[self.ani_pos])

So, maybe if you changed this last line to the code below, it would stop going over the end of the list (stay on the only record in it)

self.img = pygame.image.load(self.ani[0])

I probably don't know what I'm talking about since I know nothing about python.

I fixed it now was a simple misspell error.

It is complaining that you tried to access an element that doesn't exist in an list.

In the stack trace it will show you exactly where is the problem, but - unless it is an internal pygame call - the only points that it can be are here:

                self.img = pygame.image.load(self.ani[self.ani_pos])

And here:

        self.img = pygame.image.load(self.ani[0])

You can either use pdb to debug it or print those lists to check what is inside and how many elements they have.
