Hi all,
Coming up for air here. :)
I'm experimenting with using swipe gestures to move between cards on both iOS
and Android. I set acceleratedRendering to true on preOpenStack. I am using a
fairly simple script in a background group that is on every card. Here is the
group script:
on mouseDown
put the mouseH into sStartH
end mouseDown
on mouseUp
if abs(the mouseH - sStartH) > 50 then
if the mouseH < sStartH then
goNext
else
goPrev
end if
end if
end mouseUp
command goNext
lock screen for visual effect
go to next card
unlock screen with visual effect push left
end goNext
command goPrev
lock screen for visual effect
go to prev card
unlock screen with visual effect push right
end goPrev
This works well on both an iPad 1 and a new Asus Transformer. But only on the
first couple of swipes. After that there is a severe time lag before the card
transition happens. It's worse if I try to move rapidly between cards. Usually
(but not always) if I wait five or so seconds between swipe gestures it
responds immediately. There seems to be no difference in this behavior between
the old 1st gen iPad and the new Asus tablet, so it seems to be a problem with
the LiveCode engine.
Has anyone else seen this? Is there a better way to respond to swipe gestures?
