  1. when the user presses the screen, store the position firstPressLocation
  2. when the user releases the finger store lastPressLocation and do the following:
  • calculate the velocity by vel = (lastPressLocation-firstPressLocation).normalized * speed

Improving it so a small drag fires less would be to also multiply it by screen height or other fixed factor. Personally, I use units and never go into screen space so I would have converted the touch into world space first for resolution independence.

But good luck. It’s a trivial problem.

sorry to disappoint you, but you asked twice about video tutorial - nowhere did you mention that you have already watched that very same official tutorial video. So I provided it. I don’t have any other tutorial for you however.

RajRajRaj: I remember reading this, I fear it’s bit complicated, however, do you actually need full path?

Maybe just show direction and length of pull, that might be enough for player, and way easier to code?
