Pygame Shooting Bullets

Recently ive been trying to create a small game using Pygame, Ive managed to display an image which can move side to side, the trouble ive been having is enabling it to fire bullets using the space bar.

Heres my code so far: http://pastebin.com/24xDYwY7

Ive now got the bullet to display however it doesnt come out from the "turret.png", and just sits in the top left of the screen.

Is anyone able to help me with this? I am extremely new to python and would appreciate the help

It looks like you're using a technique I like employing in PyGame - using different sprite Groups for separating good guys, bad guys, bullets, blocks, etc… with a single unified 'all the things' Group.

What I don't see is the all_sprites.update() call that makes the whole thing work, though I do see player.update(). PyGame groups are designed to let you call group.update() in place of a for x in y call such as:

for sprite in my_sprites:
    sprite.update()

EDIT: Not seeing your images in the right place? If they're being set to the upper-left corner, this is usually because nothing is setting the surface of the drawn image to appear where you want it to.

One thing I've found handy about PyGame's get_rect() call is that it allows you to pass arguments to set attributes of the rect you get back. For example, my sprite.draw(self) methods tend to look something like this:

def draw(self):
    """Sets the image's Rect to the middle of the sprite, 
    then blits to the screen.
    """
    draw_rect = self.drawn_image.get_rect(center=self.rect.center)
    SCREEN.blit(self.drawn_image, draw_rect)

This assumes that the sprite object's self.x and self.y are being updated correctly as well, but it's essentially the right thing to do; get the rect for the object you're drawing, set it to the right coordinates just as you do the actual sprite, then pass the image and the rect to SCREEN.blit().
