Re: [pygame] move problems
Have a look at my game's game.py file for your key problem. Love,tullaris. http://www.mediafire.com/?l4md0edjnmm 2009/2/11 Yanom Mobis ya...@rocketmail.com this code is in my main game loop key = pygame.key.get_pressed() #create a key index if K_UP in key: #check if the up arrow is pressed redcar.speed = (0, -2) else: redcar.speed = (0, 0) redcar.rect = redcar.rect.move(redcar.speed) #move redcar by speed but pressing the up arrow doesn't move the sprite.

Re: [pygame] move problems
Here's an example: UP= 0 DOWN = 1 LEFT = 2 RIGHT = 3 keys = [0, 0, 1, 0] #up, down, left, and right keys, respectively. 0 stands for 'not pressed', 1 stands for 'is pressed'. if LEFT in keys: print True Now, it won't work, because 2 is not in the keys list. if keys[LEFT]: print True This works, because you're checking to see if the 3rd numeral in the list is positive/true.
