Help out a complete noob, my friends.. :-)
I found this:
"Compare the speed of a specific touch (given by its zero-based index). Touch speed is measured in canvas pixels per second, so is not affected by scaling the display."
Can you help me understand what the index is used for?
In my case I want to detect the speed of a drag and drop menu item to decide wether it is flicked out of the screen or goes back into place.
Where and how would I do that?
