This collection of tutorials is an excellent reference point for teachers or students who want to review the most important and foundational scripting concepts for developing with Unity. If you are unsure whether or not you understand a particular coding concept or if you want to make sure you have all your bases covered, reviewing the tutorials here can be very helpful. 

Before reviewing the tutorials here, it is recommended that you have completed at least one beginner project in Unity to provide more context, such as:

Learn about programming for game development, from the very beginning with these easy to follow video tutorials.

Beginner Scripting

e0b6a232-30bb-558f-b20c-bad17b21bfa0:mbfIqfmmzOil0ADVQTFuPu

Understand high-level programming concepts (such as inheritance, encapsulation, data abstraction, and polymorphism) and how they are implemented. 

Level 2 Programming theory

How to use Classes to store and organize your information, and how to create constructors to work with parts of your class.

This tutorial is included in the Beginner Scripting project.

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
