creating an object at another objects position

[deanhystad]

You cannot do this:

while True:
    r.mainloop()
    r.update()
    for Laser in Laser.lasers:
        Laser.update()
        time.sleep(0.05)

mainloop is a blocking function call. It will never return. You will never call r.update() and you will never call any of your laser update code.

If you want to make a game you are much better off starting with PyGame or some something similar.
