Help with shooter.

[chris99]

Currently, all the functions work as expected, but the moving left and right. I want to alter my code to allow me to hold down right and left and for it to continue moving. I know there is a statement with the right syntax, I just dont know how to apply it. As it is I need to tap the right and left keys continuously to move.

Please can someone respond? I've fixed the initial problem, but I can't delay the action with the wait or delay command. I want to "barrel roll" my plane so that it rolls across the screen. Without wait commands it moves the right distance, but it is instant. Here's the code:

screen_mode = (400,480)
colour_green = 0,255,100
def load_image(name, colorkey=None):
    fullname = os.path.join('data', name)
    try:
        image = pygame.image.load(fullname)
    except pygame.error, message:
        print 'Cannot load image:', name
        raise SystemExit, message
    image = image.convert()
    if colorkey is not None:
        if colorkey is -1:
            colorkey = image.get_at((0,0))
        image.set_colorkey(colorkey, RLEACCEL)
    return image, image.get_rect()
