Multi-Touch Swipe V or H Direction

Hi,
Has anybody worked out how to detect a 2 finger vertical and horizontal swipe? I looked at Ben's Touch Detection stack in the sample stack area but but I'm not getting what I need. Thanks in advance for the help.

Try this:
########CODE to copy and paste with your mouse#######
global gPosition
global gTouch

on openCard
put empty into gPosition
end openCard

on mouseDown
put item 1 of the mouseLoc into gPosition
end mouseDown

on mouseUp
put empty into gPosition
end mouseUp

on mouseMove pX
if gPosition is not empty and 200 < (gPosition - pX) then
put empty into gPosition
visual effect push left
go to next card #this is a typical action with swipe
if gTouch = 2 then
answer "swiped with 2 fingers!"
end if
end if
end mouseMove

on touchStart pTouchId
# Sent each time a new touch is started
add 1 to gTouch
end touchStart

on touchEnd pTouchId
# Sent each time a touch ends
add -1 to gTouch
end touchEnd

Thanks, MaxV,
I didn't realize I could use mouseLoc with a 2 finger touch.
Here's what I ended up with for a vertical swipe.

Code: Select all

local sPosition,sTouchCount,sTouchV

on openCard
  put empty into sPosition
  put empty into sTouchCount
  put empty into sTouchV
  put "2 finger virtical swipe" into fld "log"
end openCard

on mouseDown
  put item 2 of the mouseLoc into sPosition
end mouseDown

on mouseUp
  --  put "sPosition" && sPosition &CR& "sTouchV" && sTouchV &CR& (sTouchV - sPosition) into fld "log"
  
  if sPosition is not empty and (sTouchV - sPosition) > 40 then
    
    if sTouchCount = 2 then
      put empty into sPosition
      visual effect "push" down
      go card "setup"
    end if
  end if
  put empty into sPosition
end mouseUp

on mouseMove pTouchH, pTouchV
  if environment() is not "mobile" then exit to top
  
  put pTouchV into sTouchV
end mouseMove

on touchStart pTouchId
  add 1 to sTouchCount
end touchStart

on touchEnd pTouchId
  subtract 1 from sTouchCount
end touchEnd
