This example shows how to render text and build a simple Graphic Interface on top of custom world-size rendering. Often, a separate camera is used for the HUD or interface, while another camera is used to render sprites and other game elements.
The example also shows how to create an Event manager, a commonly used pattern to manage events while avoiding tight-coupling. This is to eliminate the use of globals and makes game code much more maintainable.
