WK6 Coding Game in Actionscript 3.0

Overview

I'm thinking of modifying the current shooting control mechanism of the Space Invader game.

The new control will be the status of the squares displayed on the stage and each square is connected to a specific key-down event. For instance, there are 6 squares altogether and correspond to key 1-6 respectively. Some of the squares will randomly change the status to 'activate' (in the form of switching the background color of the squares) and the user needs to press the corresponding keys to shoot.
