Cocos2d-x 与Cocosbuilder结合使用的一些技巧

转自：http://jetion.diandian.com/post/2012-12-04/40047798280，感谢作者分享

1. 使用Cocosbuilder制作帧动画，Publish的时候崩溃了。

解决方法如下：File -> projectsetting -> 取消选择 flatten paths when publishing

 

2. 使用Cocosbuilder制作完骨骼动画后，和Cocos2d-x中的Action结合，发现action只运行极短的时间就停止了。

解决方法：

其实这是因为在Cocosbuilder中设置了loop动画，在CCBAnimationManager中，当一次动画执行完毕后，它会执行stopAllAction（），而这个时候，我们的action还没有执行完毕，如果你的action的时间 > 运行一次Cocosbuilder动画的时间，就会出现这种情况。这时候我们只要稍微改一下原CCBAnimationManager中的runAniamtions()代码即可，如下：

void CCBAnimationManager::runAnimations(int nSeqId, float fTweenDuration)
{
    CCAssert(nSeqId != -1, "Sequence id couldn't be found");
                                                 
                                             
    mRootNode->stopActionByTag(100);
                                                 
    CCDictElement* pElement = NULL;
    CCDICT_FOREACH(mNodeSequences, pElement)
    {
        CCNode *node = (CCNode*)pElement->getIntKey();
        node->stopAllActions();
                                                     
        // Refer to CCBReader::readKeyframe() for the real type of value
        CCDictionary *seqs = (CCDictionary*)pElement->getObject();
        CCDictionary *seqNodeProps = (CCDictionary*)seqs->objectForKey(nSeqId);
                                                     
        set seqNodePropNames;
                                                     
        if (seqNodeProps)
        {
            // Reset nodes that have sequence node properties, and run actions on them
            CCDictElement* pElement1 = NULL;
            CCDICT_FOREACH(seqNodeProps, pElement1)
            {
                const char *propName = pElement1->getStrKey();
                CCBSequenceProperty *seqProp = (CCBSequenceProperty*)seqNodeProps->objectForKey(propName);
                seqNodePropNames.insert(propName);
                                                             
                setFirstFrame(node, seqProp, fTweenDuration);
                runAction(node, seqProp, fTweenDuration);
            }
        }
                                                     
        // Reset the nodes that may have been changed by other timelines
        CCDictionary *nodeBaseValues = (CCDictionary*)mBaseValues->objectForKey(pElement->getIntKey());
        if (nodeBaseValues)
        {
            CCDictElement* pElement2 = NULL;
            CCDICT_FOREACH(nodeBaseValues, pElement2)
            {
                if (seqNodePropNames.find(pElement2->getStrKey()) == seqNodePropNames.end())
                {
                    CCObject *value = pElement2->getObject();
                                                                 
                    if (value)
                    {
                       setAnimatedProperty(pElement2->getStrKey(), node, value, fTweenDuration);
                    }
                }
            }
        }
    }
                                                 
    // Make callback at end of sequence
    CCBSequence *seq = getSequence(nSeqId);
    CCAction *completeAction = CCSequence::createWithTwoActions(CCDelayTime::create(seq->getDuration() + fTweenDuration),
                                                                CCCallFunc::create(this, callfunc_selector(CCBAnimationManager::sequenceCompleted)));
    completeAction->setTag(100);
    mRootNode->runAction(completeAction);
                                                 
    // Set the running scene
    mRunningSequence = getSequence(nSeqId);
                                                 
}

第6行和第59行为添加的代码。

3. 给精灵添加发光的效果

在CCSprite右边的编辑窗口有一个Blend的设置项，我们只要选择下面的Additive即可实现发光效果； 手动设置Blend src为one- dst color，Blend dst为one， 可以去掉精灵的Alpha通道，这在去除某些黑色背景图片有不错的效果。

 

4.使用Cocosbuilder中的Visible动画时报错

这里要注意，是动画中的Visible，然后设置该动画为AutoRun，运行它就报错，报错内容如下：

但是如果你没设置AutoRun，而是手动的触发它，并不会报错。

暂时不知道为什么会出现这种情况，你可以灵活的使用opacity来代替显示隐藏的功能。

未完待续。。。

另外篇博客：

这样可以解决根节点的动画与2dx的action同时运作，但是无法解决子节点的问题。

完整的修改方案还需要增加这个部分的修改

 void CCBAnimationManager::runAction(CCNode *pNode, CCBSequenceProperty *pSeqProp, float fTweenDuration)
 {
     CCArray *keyframes = pSeqProp->getKeyframes();
     int numKeyframes = keyframes->count();

     if (numKeyframes > 1)
     {
         // Make an animation!
         CCArray *actions = CCArray::create();

         CCBKeyframe *keyframeFirst = (CCBKeyframe*)keyframes->objectAtIndex(0);
         float timeFirst = keyframeFirst->getTime() + fTweenDuration;

         if (timeFirst > 0)
         {
             actions->addObject(CCDelayTime::create(timeFirst));
         }

         for (int i = 0; i < numKeyframes - 1; ++i)
         {
             CCBKeyframe *kf0 = (CCBKeyframe*)keyframes->objectAtIndex(i);
             CCBKeyframe *kf1 = (CCBKeyframe*)keyframes->objectAtIndex(i+1);

             CCActionInterval *action = getAction(kf0, kf1, pSeqProp->getName(), pNode);
             if (action)
             {
                 // Apply easing
                 action = getEaseAction(action, kf0->getEasingType(), kf0->getEasingOpt());

                 actions->addObject(action);
             }
         }

         CCFiniteTimeAction *seq = CCSequence::create(actions);
         // 修改
         const int childActionTag = 200;
         seq->setTag(childActionTag);

         pNode->runAction(seq);
     }
 }

以及

 {
     CCAssert(nSeqId != -1, "Sequence id couldn't be found");
     // 修改部分

     {

         // 修改部分
         const int childActionTag = 200;
         node->stopActionByTag(childActionTag);
         //node->stopAllActions();

         // Refer to CCBReader::readKeyframe() for the real type of value
         CCDictionary *seqs = (CCDictionary*)pElement->getObject();
         CCDictionary *seqNodeProps = (CCDictionary*)seqs->objectForKey(nSeqId);

         set seqNodePropNames;

         if (seqNodeProps)
         {
             // Reset nodes that have sequence node properties, and run actions on them
             CCDictElement* pElement1 = NULL;
             CCDICT_FOREACH(seqNodeProps, pElement1)

                 CCBSequenceProperty *seqProp = (CCBSequenceProperty*)seqNodeProps->objectForKey(propName);
                 seqNodePropNames.insert(propName);

                 setFirstFrame(node, seqProp, fTweenDuration);
                 runAction(node, seqProp, fTweenDuration);
             }
         }

         // Reset the nodes that may have been changed by other timelines
         CCDictionary *nodeBaseValues = (CCDictionary*)mBaseValues->objectForKey(pElement->getIntKey());
         if (nodeBaseValues)

                 {
                     CCObject *value = pElement2->getObject();

                     if (value)
                     {
                        setAnimatedProperty(pElement2->getStrKey(), node, value, fTweenDuration);
                     }
                 }
             }
         }
     }

     // Make callback at end of sequence

     CCAction *completeAction = CCSequence::createWithTwoActions(CCDelayTime::create(seq->getDuration() + fTweenDuration),
                                                                 CCCallFunc::create(this, callfunc_selector(CCBAnimationManager::sequenceCompleted)));

     // 修改部分
     completeAction->setTag(currentActionTag);
     mRootNode->runAction(completeAction);

     // Set the running scene

     if(seq->getCallbackChannel() != NULL) {
         CCAction* action = (CCAction *)actionForCallbackChannel(seq->getCallbackChannel());
         if(action != NULL) {
             mRootNode->runAction(action);
         }
     }

     if(seq->getSoundChannel() != NULL) {
         CCAction* action = (CCAction *)actionForSoundChannel(seq->getSoundChannel());
