This sample demonstrates how to use GameplayKit’s entity-component feature to create modular, scalable game architecture. It covers the classes GKEntity, GKComponent, and GKComponentSystem.

The Game object sets up the entities and their components. Each box is represented by an instance of the GKEntity class -- an abstract container for the GKComponent objects that together provide each entity's functionality.

Each box shows the effect of a different combination of the following components:

• All boxes have a GeometryComponent that manage their SceneKit representation for display and physics simulator.
• Boxes with a ParticleComponent also display a fiery or sparkly particle effect.
• Boxes with a PlayerControlComponent jump up into the air when you interact with the scene.

In the Game object's setUpEntities method, try adding a particle or player-control component to the purple box.

Tap anywhere (iOS), press any key (OS X), or click the Siri Remote touch surface (tvOS) to interact with the scene, causing boxes with a PlayerControlComponent to jump.
