how to change button state upon swiping and tapping?

Dear all,

I need some help on making a single button that changes state and appearance, either upon tapping or swiping it. the button stays in place, just that tapping it changes it to state 1 or the previous. and that swiping it changes it between 2 and 3. i managed to create the tapping function in c# (as a supreme noob), but i cannot find any hlp on a script to manifest the swiping function. i hope someone can help me, or point me into the right direction.

thanks in advance
