Hi all!
I'm using the old way to catch touches on my sprites, using foreach to check each sprite inside a rectangle. No problem with that. Testing on iPhone I saw my sprite lagging behind my finger when I start to move. It seems like the position update is being done more often than draws. Also, after it starts moving, you can't notice lags anymore.
I tried TouchesTest and it suffers from the same problem. When you move a bar it takes a while to follow your finger. Did you see this problem on your games?
Thanks!!
