Hi all ,
I am trying to move my character by following gesture : User swipes on screen ( this swipe determines which direction character is suppose to move ) and then without lifting the finger holds it down on the screen . When user holds it down i want it to keep looping (calling the move command with specific direction ) until user takes his finger off the screen . I tried using `touchphase.Stationary` instead of `touchphase.ended` which i am using in my current script , the results were wonky and weird and not perfect and i am clueless as to where to start. I hope somebody from here will b able to help me out .
