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.
