Questions tagged [component-based]
Component-based designs rely on separating the multiple logical attributes of business objects and game objects into small components dedicated only to specific tasks. Whereas game objects are usually modeled to reproduce the attributes and behavior of "real world" objects by aggregating them together and allowing specialized objects to inherit from general ones, component based design relies on composition rather than inheritance.
