Setting up the layout

As always, we'll begin by creating the layout for our game. Unfortunately, for us, there is no sprite in freebundle.zip that fits a battle tank game. However, we can use two sprites to make a tank: one sprite for the base of the tank and another one for the turret.

First, add two sprite objects to the layout and name them tankTurret and tankBase. The tankBase sprite is from UI elements\Adventure pack. Pick any square icon; in this example, I will use the buttonSquare_blue_pressed image. For the turret, pick an arrow image that points to the right, such as arrowSilver_right.
