Documentation: GameObject Components
The GameObject is the base entity in the Game, anything is the scene is a GameObject.
However, using simply game objects does not allow to express the meaning carried by an entity.
In this pattern, we separated between GameObjects and their carried context.
- GameObjects does not physically exist
- GameObjects are nothing.
- GameObjects are just Containers and organized in hierarchy
As for Components, they are objects that carry a specific context, logic, behavior. They cant exist by their own within a scene, as they need a host obejct.
Combining both GameObjects and Components allows to create a GameObject with a specific context.
- Each component added to the game object gives it additional logic.
- The context carried by a GameObject is defined by all the components within this game object.
- The same component can be added by many GameObjects
In the piture above, (we consider) it shows all exisiting components ( shown by blue circle ). Orange rectangles represent GameObjects, they can add as many components as they needed, each specific combination of linkage define a new & unique context for the GameObject.
