This collection of tutorials is an excellent reference point for teachers or students who want to review the higher-level conceptual concepts for developing with Unity. The tutorials included here are intended for people who already have experience with basic scripting and want to understand at a more conceptual level what they’re doing and what is possible with scripting. These skills and concepts are fundamental for anyone who is considering entering the field of computer science.

Before reviewing the tutorials here, it is recommended that you understand all of the concepts covered in “Beginner Scripting” and have completed at least one or two more complex projects or creator kids, such as:

This project contains essential knowledge for intermediate level scripting with these video tutorials.

 How to create, implement, and call an extension method. 

Games

Enable easier readability and debugging by correctly organizing classes to include only singular purpose code

Add new functionality to non-editable classes by applying extension methods

Organize and prevent conflicts between scripts by using namespaces

Manage the communication of a GameObject’s status changes to other objects in the application by using Events 

Write efficient, organized, and comprehensible code by correctly implementing the principles of object-oriented programming

using UnityEngine;
using System.Collections;

//It is common to create a class to contain all of your
//extension methods. This class must be static.
public static class ExtensionMethods
{
    //Even though they are used like normal methods, extension
    //methods must be declared static. Notice that the first
    //parameter has the 'this' keyword followed by a Transform
    //variable. This variable denotes which class the extension
    //method becomes a part of.
    public static void ResetTransformation(this Transform trans)
    {
        trans.position = Vector3.zero;
        trans.localRotation = Quaternion.identity;
        trans.localScale = new Vector3(1, 1, 1);
    }
}

using UnityEngine;
using System.Collections;

public class SomeClass : MonoBehaviour 
{
    void Start () {
        //Notice how you pass no parameter into this
        //extension method even though you had one in the
        //method declaration. The transform object that
        //this method is called from automatically gets
        //passed in as the first parameter.
        transform.ResetTransformation();
    }
