I hate video tutorials; they're slow, you have to consume them linearly / it's hard to skip around, and frankly I just don't think they add much unless cursor movements really matter, as in a ZBrush DVD or something. Textbooks (like, made out of paper) also suck because you can't click on the words.
Jasper Flick's Unity coding tutorials, then, are a revelation: a short essay, written in plain language, rendered on a clean webpage with non-patronizing glossary, just enough screenshots, and code snippets that link you to the relevant documentation. Wow.
You'll learn a lot about C# concepts / syntax too, which is what makes this series especially great, a focus on general fundamentals. So many tutorials hinge on a structure like "use rigidbodies to make enemies die" but Flick is more about "make enemies die to learn how to use rigidbodies."
The impeccable structure comes at a significant time-cost to Flick, so he's soliciting donations to add more tutorials, using a pretty novel timer mechanism.
Maybe I'll chip in. I just read his tutorial on mesh generation and custom inspectors and I feel like I can take on the world now.
