I’m bumping this because it’s my most pressing issue, and also because there’s a typo in the original code posted above.
I have found out that if I do:
// first pair frameWidth: 7 frameHeight: 11 // second pair height: 43 width:28
then the ninja is animated at the correct size.
If I comment out either pair of specifiers, it gets it wrong. I think that the second pair should not be needed.
