I found that CCSkewBy can’t work SkewY, but it can work SkewX! Why ? is it a bug?
This is real a bug!In the CCSkewTo::startWithTarget function. there is a wrong statement “m_fSkewY = pTarget~~>getSkewY;", and the right statement "m_fStartSkewY = pTarget~~>getSkewY();”!
The code is m_fStartSkewY = pTarget->getSkewY();May be your code is too old.
My code is “cocos2d-1.0.1-x-0.9.1”. It also have the problem!
I have rechecked the code, yes, it is the same as you said. I didn’t know what I see yesterday.
It is corrected in https://github.com/cocos2d/cocos2d-x/pull/489.Thank you.
