child 로 달린 것들 opacity 조절하는 코드.

void setOpacity(CCObject* object, GLubyte opaque) { CCArray* childs = NULL; CCObject* child = NULL; CCNode* nodeObject = (CCNode*)object; if (nodeObject) { childs = nodeObject->getChildren(); } if (childs) { CCARRAY_FOREACH(childs, child){ CCRGBAProtocol *pRGBAProtocol = dynamic_cast<CCRGBAProtocol*>(child); if (pRGBAProtocol) { pRGBAProtocol->setOpacity(opaque); // pRGBAProtocol->setColor(ccc3(opaque, opaque, opaque)); } CCNode* singleObject = (CCNode*)child; if (singleObject && singleObject->getChildrenCount()>0) { setOpacity(singleObject, opaque); } } } }
