UE4 Mobile - How to get speed of player swipe?

Hello all,

I am trying to get the speed of the players finger swipe, so the faster the player swipes, the faster the ball goes.
In blueprint if possible.

Any way of doing this?

Thanks in advance.

The faster the swipe is the bigger the difference between the (Old_2 / New_2) variable.

Grab youre input touch state location and set 2 variables with a delay between them. Get the two variables, subtract them from each other. Set a third variable with the difference. The faster the swipe the greater the difference.
