Terry, I'm interested in this also.
Get the SivaSiva app ( no space... from iOS and Google Play)
In the Listen Module, with Elanor's help, I tried to set up a "Spotify" UX with
categories of audio scroll and up and down, and within on categories, left to
right.
I also get, what is a probably the same as you get, a "conflict" between Elanor
touch events -- from scrolling left with right and up and down.
In this case we don’t use the mobileScroller at all in mobile, both up and
down, left and right, are implement with touch. But I think it is the same
thing as you have...
What I am seeing is: when the up and down in active, the left to right touch is
disabled. It "kinda" works for the user but is very "clunky". I tried playing
with touch startx and y numbers. It gets "worse" as you go down in size.
The script is small enough to put here. Would be nice of this were fixed but I
don’t seeing how the engine would do it. It would seem that the pTouchX and
pTouchY are managing the scroll independently.
So you try a "swipe" gesture with your thumb that goes "diagonally" that is,
changes is location on the both "x" and "y" axes ... the engine is going to
focus on say just the "y" cords -- you get an up to down scroll or vice-versa--
but "x" coord are not "seen" and you don't get any left of right behavior --
in you case, a card swipe, in my case a group swipe left to right fails.
Until you stop and "focus" carefully on "x" axes gesture (left to right, or
vice versa). then you get you Card/Group swipe horizontally...
on touchStart pTouchID
put empty into sStartX
put empty into sStartY
put the vScroll of grp "all-collections" into sStartYScroll
put the long owner of the target into tHGroup
put the hScroll of tHGroup into sStartHScroll
end touchStart
on touchMove pTouchID, pTouchX, pTouchY
if sStartY is empty then
put pTouchY into sStartY
end if
if sStartX is empty then
put pTouchX into sStartX
end if
// Check for vertical scroll
if pTouchY > (sStartY + 20) or pTouchY < (sStartY - 20) then
set the vScroll of group "all-collections" to sStartYScroll +
(sStartY-pTouchY)
else
if pTouchX > (sStartX + 10) or pTouchX < (sStartX - 10) then
// Check for horizontal scroll
put the long owner of the target into tHGroup
set the hScroll of tHGroup to sStartHScroll + (sStartX-pTouchX)
end if
end if
end touchMove
on touchEnd pTouchID
-- code
end touchEnd
on touchRelease pTouchID
-- code
end touchRelease
I wish there was are easy fix...but I suspect "not"

This is a problem that I have run into before and have never been able to
solve satisfactorily. I’m using touchStart and touchEnd handlers to detect the
direction and speed of a finger movement and if it is within certain bounds
(large enough x, small enough y, and fast enough) then the user can swipe back
and forwards through a series of cards. Good so far except when the area they
are swiping on also includes a mobile scroller (to scroll a list selection
widget/thingy). In that situation the swiping becomes a bit of a hit and miss
thing – works sometimes but not others. On iOS there are a few scroller
parameters look potentially useful (canCancelTouches, delayTouches, and
lockDirection) but it’s not really clear (to me at least) which of these might
help and if so whether I should be setting them to true or false.
Any ideas?
Terry...
