A Renderer is responsible for reading the game state and telling the game engine what to draw to the screen.

Remember: Encompass isn't a game engine and it doesn't have a rendering system. So Renderers aren't actually doing the rendering, they're just telling the game engine what to render.

There are two kinds of renderers: GeneralRenderers and EntityRenderers.
|
||
|
|
|
||
|
|
A GeneralRenderer is a Renderer which reads the game state in order to draw elements to the screen. It also requires a layer, which represents the order in which it will draw to the screen.
|
||
|
|
|
||
|
|
An EntityRenderer provides a structure for the common pattern of drawing an Entity which has a particular collection of Components and a specific type of DrawComponent. They also have the ability to draw DrawComponents at their specific layer.
|

For 2D games, you will need to be specific about the order in which things draw. For a 3D game you will probably end up delegating rendering to some kind of scene/camera system.
