HI I follow the Chapter 2 - How to Add a sprite
and i got problem when i want to change the background color.
when i change the CCLayer to CCLayerColor…the CREATE_FUNC(Helloworld), got error
The type ‘HelloWorld’ must implement the inherited pure virtual method ‘cocos2d::CCRGBAProtocol::setOpacity’
i dun know why will cause this, i search in internet,and find out some other guys have this problem, but cant find soultion
