Visual effect problems in iOS

[Graham Samuel]

Thanks Chris

I am embarrassed to say that my card-to-card effects are now working! I had a completely repeatable recipe to show they won't working yesterday, but a restart of my machine and a test immediately afterwards (both on the simulator and the iPad itself) showed the effects working fine. Since I hadn't changed the code of my app between the two tests, I can only think that I somehow messed up the IDE with other stuff I did in the previous sessions. If I find out exactly how to cause the problem, I will report it. Meanwhile thanks for the advice. 

Right now I no longer want to do stack-to-stack transitions, but your advice on this will be stored away in the scrapbook for later use.

Back to the next problem - embedded sounds.

I've found that if something like this is not working, it's usually because I have some kind of error that's occurring in the script (usually preOpenCard) of the card I'm trying to go to. Nothing to do in this case but debug and try to figure out what's going on. With that said, I have actually found, and I believe others have as well, that you get a very slight performance boost if you use the "lock screen for visual effect" command instead of the above method. So something like:

There are probably others. I was also having issues with this at one point, and I found this worked just fine. Something like:

> 	go cd "someCard" of stack "theToStack"
> 	close stack "theFromStack"

It's supposedly not necessary to do that, as in iOS only one stack is open at a time, but, once again, I found that the effect did not work correctly if I didn't issue that command.
