So I have been giving Unity a try for the next game demo. I find that Unity has a lot of resources created online on YouTube and Websites.

During my DuckDuckGo Search & Google I cam across a few channesl to aid me in learning Unity and the C# Scripting concepts.

Brackeys

Brackeys Channel has been around for quite a long time. He convers a lot of Basic Unity Editor Tutorials and Scripting in C#. I Learned quite a bit from his tutorials. Sadly he has stopped posting and creating new tutorials in his Goodbye video. But the concepts is still relevant even if you use later versions of Unity.
