# ScriptableObjects

Scriptable Objects are essentially 'MonoBehaviors' but are not structured to be used as a gameObject's component. : Scriptable Objects don't require being attached to a GameObject, doesn't need to be (can't be) associated with a scene, transform, etc. SO's do not get standard Unity 'callback methods' like Start( ) , Update( ) etc, which means they don't have a 'frame-based' lifecycle. They can be 'serialized' (saved by the system) and viewed in the inspector. [Richard Fine - Video 9:45](https://www.youtube.com/watch?v=6vmRwLYWNRo)

## Patterns:(video 21:30)

* DataObjects and Tables - Example - When killing a goblin, what are the items that the object can drop? Data: DropObject, ChanceOfDropping
* Extendable Enums - Empty ScriptableObjects bound to Asset Files - Example: DamageTypes. You can compare, test equality on an emtpy object, ie: use as Dictionary Keys. Benefit is that it's easy to add new values without changing 'code'.
  * Dual Deserialization - Supports JSON Utility for saving, loading data: 
  * Example: Level Layout - Editor with Level Data such as Platform, Player, Coin, Enemy position data.
  * Reload-Proof Singletons <br>

    Delegate Objects: Scriptable Objects can contain methods, ( not just data ) - Strategy Pattern
