First steps

This tank game will be a two-player combat game modeled after the kind of simple action game you might find on a classic 1980s game system. One player will be at the top of the screen, one at the bottom, and the two tanks will move constantly from left to right while each player tries to shoot the other with a single bullet.

These constants will be used throughout the game code to calculate sizes and locations. In fact, we'll use two of them right away in MainWindow.__init__():

 self.resize(qtc.QSize(SCREEN_WIDTH, ...
