-
find function nodeToParentTransform in CCNode class
-
add code after “float y = m_tPosition.y”, as follow:
y = (m_parent ? m_parent~~>getContentSizeInPixel.height : CCDirector::sharedDirector~~>getWinSizeInPixels.height)~~ y~~ m_tContentSize.height;
So, now you can use setPosition function by leftHand coordinates.
This just make the draw work. The touch system should use other way, 敬请期待! _
