Anything that gets drawn or contains things that get drawn is a CCNode. The most common CCNodes are: CocosSharp.CCScene, CocosSharp.CCLayer, CocosSharp.CCSprite and CocosSharp.CCMenu.

The main features of a CocosSharp.CCNode are:

• They can contain other Node nodes (AddChild, GetChildByTag, RemoveChild)

• They can schedule periodic callbacks (Schedule, Unschedule, etc)

• They can execute actions (RunAction, StopAction)

Subclassing a CCNode involves initializing resources and scheduling any desired callbacks as well as overriding the draw method to render the node.
