Running the game

You can now run the game and see the fruits of your labor:

Figure 18.5 – Running the game

As you can see, for the first time, we have actual button positions marked out on the screen: move up and down in the bottom-left corner and fire and flip direction in the bottom-right corner. The button in the top-right corner will start the game when it is game over and it will pause and resume the game when it is in play. At the moment, the buttons don't do anything, but we will fix that soon.

In addition, we have text being drawn to the screen to show the lives, score, and high score. There is also a message to the player to advise them on how to start the game.
