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 utilize the quaternion system to manage the rotation of game objects. 

Games

Identify potential simplification opportunities in code, such as splitting methods and reusing variables

Identify unnecessary nested if statements

Differentiate between public variables (properties), private variables (fields), and local variables

Store and organize data by applying data structures such as lists and dictionaries

Maximize code efficiency by correctly executing coding best practices

using UnityEngine;
using System.Collections;

public class MotionScript : MonoBehaviour 
{    
    public float speed = 3f;


    void Update () 
    {
        transform.Translate(-Input.GetAxis("Horizontal") * speed * Time.deltaTime, 0, 0);
    }
}


using UnityEngine;
using System.Collections;

public class LookAtScript : MonoBehaviour 
{
    public Transform target;


    void Update () 
    {
        Vector3 relativePos = target.position - transform.position;
        transform.rotation = Quaternion.LookRotation(relativePos);
    }
}

using UnityEngine;
using System.Collections;

public class GravityScript : MonoBehaviour 
{
    public Transform target;


    void Update () 
    {
        Vector3 relativePos = (target.position + new Vector3(0, 1.5f, 0)) - transform.position;
        Quaternion rotation = Quaternion.LookRotation(relativePos);

        Quaternion current = transform.localRotation;

        transform.localRotation = Quaternion.Slerp(current, rotation, Time.deltaTime);
        transform.Translate(0, 0, 3 * Time.deltaTime);
    }
}


using UnityEngine;
using System.Collections;

public class SomeClass : MonoBehaviour 
{
    void Start () 
    {
        transform.rotation = Quaternion.identity;
