Floating based control design allows for the input to be used over a large area. Where ever the finger touches becomes the center point of input. This form of input is well used for any hand size providing natural comfort. However it can be less responsive than an Analog stick using a larger pad.
What you will need
* Sprites that you would need for either Analog or Angle input
* Variables that you would also need for Analog of Angle input
* Optional use a large invisible sprite
Event Sheet for coordinate checking
Event Sheet for area sprite
How it works
In either method for floating control there are two steps. get where the touch event occurred to use as the center point and to hide the controls when released.
