In this version we are going to add lasers. We want the ship to be able to fire, but we don't want a constant stream of shots. We want the laser to requite time to cool down between shots. We are going to handle this with a variable called "laser reload." Every time the player shoots (spacebar) the variable is set to 10. Every time through the player's loop the variable should decrease by one. When the variable reaches 0, the player can fire again. Here are the bugs you need to fix this time around: 1. Something is wrong with the firing controls. You can only fire once. 2. The laser does not disappear when it hits the top of the screen. 3. The laser seems to fire from somewhere to the right of the ship. it should come from the ship itself.
