Looking at my own code, I never checked the coordinates in the Begin/End states. I just treated them as separate events, no related to the position on the screen. In the End case I assume the last coordinates sent by Changed.
And in the Begin case I cannot trust the coordinates because they were determined after the gesture moved a little and the gesture began, so I ask my tap recognizer where the initial coordinates were.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
