Game Objects

Basic concepts

If a script class is derived from Monobehavior, it must be attached to a game object in the editor and become a component.

How to get a component

Imagine a game object called GameManager with a script attached called GameData. This is how we get the GameData component:

private GameData gameData;

void Start () 

{

     gameData = GameObject.FindWithTag ("GameManager").GetComponent<GameData> ();

}

Efficiency

Calling GameObject.FindWithTag is more efficient than calling GameObject.Find
