Well, there is only one way for learning anything… Repetition!! You should read and do most of the tutorials unity has >> https://unity3d.com/es/learn << they cover mostly all the functions unity has to offer, you can also take mini courses on youtube… there is great info there, even some advanced neural networks, and online gaming… another road you can take… is to buy an online pay course of unity in Udemy.com or other you can find in google. In my personal opinion, you just need to have a very well organized and standardized workflow … a very good understanding on what does unity have to offer and then just let creativity take over to become a pro…!

simpliv is the Best Resource to learn Unity. The course is completely project based (top down approach), and we are going to create and publish a complete IAP featured game using Unity Game Engine.
