A quick look into the implementation of CCActionScaleBy shows that it plays around with the scale
property of the node while not tampering the contentSizeInPoints
property. The boundingBox
is the rect obtained using 0,0 as origin and contentSizeInPoints
property for width and height dimensions.
An easy way to obtain the actual width and height would be to multiply contentSize/boundingBox.size
with the current scale value:
CGFloat actualWidth = self.boundingBox.size.width * self.scale;
CGFloat actualHeight = self.boundingBox.size.height * self.scale;
