hi malte !

I am playing around with ae and have troubles on some cards to run aeMoveTo with following error message:

stack "animationEngine": execution error at line n/a (Chunk: can't find background), char 1
when i use aeLockMove the problem occurs at aeUnLockMoves ... without the lock immediately

I have no idea how i can debug this topic.

thank you in advance,
harald

Hi Harald,

the test stack you attached does not appear to expose the behavior you describe.

Are you seeing this when you are switching cards? What the error message suggests to me is that the object a running aeHandler is trying to refer to does not, or no longer exist. If you indeed see this when switching cards, please try:

on closeCard
aeStopMoving "all"
pass closeCard
end closeCard

Hope that helps a little,

malte

Actually, after reading the commented out part of your scripts:

Please make sure all your references in the aeCall do really exist. if you refer to the loc of another control, maybe that control is currently not existing.
Just to explain why you see it on aeUnlockMoves... If aeLockMoves is true, all calls to aeMoveTo are not executed immediately, but instead written to an event queue that is being executed once aeUnlockMoves is issued that queue is being processed.

All the best,

Malte

I closed the stacks and livecode and restart everything - works. I will try to reproduce it ...

thank you !
