一、問題

今天在使用cocosBuilder時，
執行程式遇到了unsupported property now的錯誤。

二、解決辦法

我使用的
cocosBuilder版本為2.1
cocos2d-x版本為2.0.4

原來是因為這一版的CCBReader(cocos2d-x官方內建的cocosBuilder解析器)，
官方忘了將物件visible的屬性判斷寫進來。

只要在libs\extentions\CCBReader\CCBAnimationManager.cpp的setAnimatedProperty函式
加上以下的code即可解決

            //加入以下的code
            else if (strcmp(pPropName, "visible") == 0)
            {
                bool visible = ((CCBValue*)pValue)->getBoolValue();
                ((CCSprite*)pNode)->setVisible(visible);
            }

這是cocos2d-x 2.0.4版CCBAnimationManager.cpp->setAnimatedProperty函式最後的樣子

void CCBAnimationManager::setAnimatedProperty(const char *pPropName, CCNode *pNode, CCObject *pValue, float fTweenDuraion)
{
    if (fTweenDuraion > 0)
    {
        // Create a fake keyframe to generate the action from
        CCBKeyframe *kf1 = new CCBKeyframe();
        kf1->autorelease();
        kf1->setValue(pValue);
        kf1->setTime(fTweenDuraion);
        kf1->setEasingType(kCCBKeyframeEasingLinear);
        
        // Animate
        CCActionInterval *tweenAction = getAction(NULL, kf1, pPropName, pNode);
        pNode->runAction(tweenAction);
    }
    else 
    {
        // Just set the value
        
        if (strcmp(pPropName, "position") == 0)
        {
            // Get position type
            CCArray *array = (CCArray*)getBaseValue(pNode, pPropName);
            int type = ((CCBValue*)array->objectAtIndex(2))->getIntValue();
            
            // Get relative position
            CCArray *value = (CCArray*)pValue;
            float x = ((CCBValue*)value->objectAtIndex(0))->getFloatValue();
            float y = ((CCBValue*)value->objectAtIndex(1))->getFloatValue();
            
            pNode->setPosition(getAbsolutePosition(ccp(x,y), type, getContainerSize(pNode->getParent()), pPropName));
        }
        else if (strcmp(pPropName, "scale") == 0)
        {
            // Get scale type
            CCArray *array = (CCArray*)getBaseValue(pNode, pPropName);
            int type = ((CCBValue*)array->objectAtIndex(2))->getIntValue();
            
            // Get relative scale
            CCArray *value = (CCArray*)pValue;
            float x = ((CCBValue*)value->objectAtIndex(0))->getFloatValue();
            float y = ((CCBValue*)value->objectAtIndex(1))->getFloatValue();
            
            setRelativeScale(pNode, x, y, type, pPropName);
        }
        else 
        {
            // [node setValue:value forKey:name];

            // TODO only handle rotation, opacity, displayFrame, color
            if (strcmp(pPropName, "rotation") == 0)
            {
                float rotate = ((CCBValue*)pValue)->getFloatValue();
                pNode->setRotation(rotate);
            }
            else if (strcmp(pPropName, "opacity") == 0)
            {
                int opacity = ((CCBValue*)pValue)->getByteValue();
                (dynamic_cast(pNode))->setOpacity(opacity);
            }
            else if (strcmp(pPropName, "displayFrame") == 0)
            {
                ((CCSprite*)pNode)->setDisplayFrame((CCSpriteFrame*)pValue);
            }
            else if (strcmp(pPropName, "color") == 0)
            {
                ccColor3BWapper *color = (ccColor3BWapper*)pValue;
                ((CCSprite*)pNode)->setColor(color->getColor());
            }
            //加入以下的code
            else if (strcmp(pPropName, "visible") == 0)
            {
                bool visible = ((CCBValue*)pValue)->getBoolValue();
                ((CCSprite*)pNode)->setVisible(visible);
            }
            else
            {
                CCLog("unsupported property name is %s", pPropName);
                CCAssert(false, "unsupported property now");
            }
        }
    }
}

記得，
除了專案裡的extension\CCBReader\CCBAnimationManager.cpp要改以外，
cocos2dx安裝目錄底下extensions/CCBReader\CCBAnimationManager.cpp也要改，
Android那邊才會顯示正常。
