-entityx::Entity-entityx::Component (EC) systems are a form of decomposition that completely decouples entity logic and data from the entity "objects" themselves. The [Evolve your Hierarchy](http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/) article provides a solid overview of EC systems and why you should use them.

 EntityX is an EC system that uses C++11 features to provide type-safe component management, event delivery, etc. It was built during the creation of a 2D space shooter.
