In this chapter, we will be making a tribute to the "Light Cycles of TRON" game from the golden era of arcades. Each player has a bike driven in an enclosed game field. The bike has a fixed speed, and can only turn at right angles. The bike leaves a wall as a trail behind it. It is fatal to run into the walls created by the bikes. It is also fatal to run into the outside walls. To put our own spin on the game, our "bikes" will be light bulbs, each with their own "glow" of the appropriate color.
This is a two-player only game. Two players can play on the same iPad (positioned at opposite ends), or via a Bluetooth connection between two iPads. The game will be fully playable between Retina and non-Retina iPads at the same time.
Our finished game will look like the following screenshot:
