How to make a simple joystick for unity3d

I made a simple joystick months ago. And use it to make a game demo – Survival Shooter Mobile. And days ago, I update the plugin and push it to github. It is pretty simple to use. And for it, I made this tutorial for learning How to Make it.

Lesson 1 Project Overview - How to make a Simple Joystick for Unity3D

About the video tutorial

I record and make these video tutorials by myself. For I do not have a studio room to live in, and I got a little cold that time, so maybe the quality of audio is a little low. To tackle it, I make the subtitle for them. ^_^

And this is my first video tutorail series. I lack of experience, if you got any suggestion or advice, please feel free to tell me.
