How fast am i sliding my finger?

DanielA

Hello everyone i was wondering if there was a way to check how fast i slide my finger across the screen. If it goes slow then its 20 or less if it goes fast then 20-60 depending on how fast superfast 60+. Please this would be a great help to me.. thanks everyone

i'd add these variables

counter, touchX, touchY..

set these when the mouse is down or a touch event happens, then increase the counter every say 0.1 seconds

then when touch/mouse is released, get the magnitude (length) of the distance between the two points (see here http://gamesalad.com/wiki/interface_reference:expression_editor) and get the value of the counter

your strength would then be equal to the magnitude divided by the counter value

eg if the user moves his finger 200 pixels in 1 seconds that's a strength of 200
if the user moves his finger 250 pixels in 0.5 seconds, that's a strength of 500

that's how i'd do it anyway... don't know if it's the best way

kk well im learning a lot right know..
@jmp909 this is what i want to happen.. Put ur finger on a actor called "left" (left is constrained to your finger) now slide ur finger as fast as u can to hit an actor called "right" and see how far "right" will fly.. im really confused about how i would do this kinda thing..
Thanks BadAsApps
