Multi-touch interface with floating virtual joystick and two types of guns

TOUCHSCREEN DEVICES ONLY

Standing on the shoulders of @wishforge-games and @stoicorum, I have made a multi-touch user interface that uses the left-side for a floating virtual joystick, and the top-right and bottom-right quarters are used for two types of guns. 

I started this project with the intention of making a simplified virtual joystick, but I ended up spending hours making a very complex one.  I hope this helps more advanced users. I plan on making a video to walk-through how it works.

In the future, I want to explore how I can make this interface work for keyboard+mouse+touchscreen (all at the same time).
