1)I don't see any error messages, but the space key won't make the torpedo fire.
2)both of your assumptions are correct
3)yes I am recycling the same bullet. Why was this the topic of some jokes? I'm new to pygame and that was probably before i joined the mailinglist.
4)i was trying to make the space key move the torpedo back to the spawnpoint, so I saw that as the easiest way.
5)I decided to move the bullet on top of the player because:
           a:: I am just making this game to test my skills, I don't care about how the graphics look
           b:: It is not checking for a collision between playerrect(the player) and torpedorect(the bullet)
           c:: It's the easier than trying to find a place to spawn it that looks good.
