  1. So I have googled for hours and played with this for hours. I have managed to make a game that works without using classes or other files but I want to make something more substantial and hence I have learned how to utilize these tools. One problem. The old method I used for movement controls doesn't port well to the way I am forced to do things via classes so I have coded a new way of handling it but for the life of me I can't seem to make it all work.   The problems hang around the self.position in __init__. I want it to give the default position of (WINDOWWIDTH // 2, WINDOWHEIGHT // 2) so it will start us in the middle of the screen but if I give it any value thats where I start and stop. I don't think it's being updated from the movement function.   I have managed to make movement sort of work with the use of a for loop before the movement ifs that looks like this:     for k in key_states:      if k.key == pygame.K_UP:           dy = -1 * MOVESPEEDY * dt       #etc for all the movement keys     But it only works in such a way that you have to repeatedly tap the movement key to make it work not able to hold it down.   Here is my code.     # Lets get to savin peeps import pygame, sys import constants import os.path from pygame.locals import * pygame.init() class Player(object):     def __init__(self):         self.color = constants.WHITE         self.position = None          #Can't remember why I put this here.     def place(self, position):         self.position = position     def draw(self, surface):         (ix, iy) = (int(self.position[0]), int(self.position[1]))         pygame.draw.circle(surface, self.color, (ix, iy,), 15)              def movementPlayer(self, dt, key_states, key_pressed):         #Heres our controls         dx = 0         dy = 0                 # key_states is a variable in main.py that reads                 # key_states = pygame.event.get(pygame.KEYDOWN)         if key_states[pygame.K_DOWN]:                       dy = 1 * constants.MOVESPEEDY * dt         if key_states[pygame.K_UP]:                      dy = -1 * constants.MOVESPEEDY * dt         if key_states[pygame.K_LEFT]:                      dx = -1 * constants.MOVESPEEDY * dt         if key_states[pygame.K_RIGHT]:                      dx = 1 * constants.MOVESPEEDY * dt         (x, y) = self.position         self.position = (x + dx, y + dy)     Now as the code stands it gives me    IndexError: Index is out of key range.   for the [pygame.K_WHATEVERS] in the if statements.   Thanks a lot for any help. and I can post additional information if needed.
