Value Observer

Value Observer is an editor-friendly implementation of the Observer pattern.

Contains:

ValueObserver<T> - observes the value change and notifies listeners. Allows to validate the value change.  

LinkedObserver<T> - connects observer located in another component and allows to use it as a field of this class.

LinkedValue<T> - connects any Serialized Property of any other component or Scriptable Object and allows it to be used as a field of this class.

Advantages:

• Very easy to use.
• Weak code dependency.
• Completely editor friendly.
• Works in play mode and in edit mode.
• Very short syntax.
• Improves the performance of your application (in cases where you check for value changes in Update or don't check for changes at all).
