Recursive extension methods

Hi, what you mention are members of a struct. Something similar to

 public struct Vector3
 {
     public float x;
     public float y;
     public float z;
 }

The Transform component has a position member of type Vector3.

Now "extension" methods extend a type. Like this :

 static public class Extensions
 {
     static public Vector3 MyMethod (this Vector3 v3)
     {
         return v3;
     }
 }

This allows you to call the new method on a variable of that type. Like

 Vector3 _position;
 _position = _position.MyMethod();

The return type must be the same as the type passed with this keyword.
