I'm using pygame, and I can't seem to figure this out. I want the user to be able to move an object on the screen, well I've tried.

I'm using a for statement, which gets the job done just as well. I think I'm just doing it wrong all together. Theres probably a good method or function that helps with it, but I just can't seem to figure it out or find it.
pygame.key.get_pressed() will return a tuple containing the current state of every key:
keystate = pygame.key.get_pressed()if keystate[K_DOWN]: box_y += 5if keystate[K_UP]: box_y -= 5if keystate[K_LEFT]: box_x -= 5#etc

Anybody know whats wrong?
Thanks,

Key states have nothing to do with the event queue - you are polling the states of every key for every event in your queue. You need to poll their states outside of your event-handling code.

How would I do it out of the event loop?
I figured out also that since it is a tuple you can't do
it's got to be:
now what I have done is made a while loop that totally updates everything
How can I do it so that it isn't in a crappy while loop like I made.
Thanks,
Joe

Keep using the event loop for some events, like WM_QUIT, but add another section of code before or after that for checking the state of the buttons.

You need to import all objects from pygame.locals ("from pygame.locals import *") for "K_UP" to work. Or, you could avoid polluting your namespace by importing the module ("import pygame.locals") and using "pygame.locals.K_UP", instead of just "K_UP".
Does that make sense?
