cocos2dx spine动画

其中要注意的几个地方：

1. 1.8版本以上的atlas做了修改 在第二行添加了size 所以只要删除size这一行即可，
2. 动作制作的时候如果层级有发生改变或者切换了skin，slot，请K帧一下，修改的部分：draworder和bone，一般首尾都K一下就行了。
3.至于.skel的binary文件，是spine本身就提供的二进制文件，性能必然高于json，本人目前正在修改完善spine runtime的binary（因为官方也不提供，完成起来慢了点，以后或许会放出）。
4.newskeletonanimation在create时候最后一个参数scale别忘了。
说一下runtime中常用的一些方法：

skeletonNode = NEWSkeletonAnimation::createWithFile("spineboy.json", "spineboy.atlas", 0.6f);//创建动作，最后的参数为scale.

 

skeletonNode->startListener = [this] (int trackIndex) {//设置动作开始检测的监听器
spTrackEntry* entry = spAnimationState_getCurrent(skeletonNode->state, trackIndex);//获得当前动作的状态信息
const char* animationName = (entry && entry->animation) ? entry->animation->name : 0;
log("%d start: %s", trackIndex, animationName);
};
skeletonNode->endListener = [] (int trackIndex) {//同理，结束动作监听
log("%d end", trackIndex);
};
skeletonNode->completeListener = [] (int trackIndex, int loopCount) {//同理，完成动作监听
log("%d complete: %d", trackIndex, loopCount);
};
skeletonNode->eventListener = [] (int trackIndex, spEvent* event) {//同理，事件监听，在spine中编辑好event导出
log("%d event: %s, %d, %f, %s", trackIndex, event->data->name, event->intValue, event->floatValue, event->stringValue);
};

skeletonNode->setMix("walk", "jump", 0.2f);//协调动作
skeletonNode->setMix("jump", "run", 0.2f);
skeletonNode->setAnimation(0, "walk", true);//设置动作，可用多个set进行动作混合
spTrackEntry* jumpEntry = skeletonNode->addAnimation(0, "jump", false, 3);//添加动作，在上个动作直接玩之后，之后为循环参数和delay
skeletonNode->addAnimation(0, "run", true);

skeletonNode->setStartListener(jumpEntry, [] (int trackIndex) {
log("jumped!");
});

skeletonNode->timeScale = 0.3f;//动作间隔
skeletonNode->debugBones = true;//debug模式
skeletonNode->update(0);//更新动作
spBone* root=skeletonNode->findBone("root");//找到name为root的骨骼，同理 通过 findslot 可以找到名字为name的slot

skeletonNode = NEWSkeletonAnimation::createWithFile("Maid.json", "Maid.atlas", 0.6f);

    skeletonNode->startListener = [this] (int trackIndex) {
        spTrackEntry* entry = spAnimationState_getCurrent(skeletonNode->state, trackIndex);
        const char* animationName = (entry && entry->animation) ? entry->animation->name : 0;
        log("%d start: %s", trackIndex, animationName);
    };
    skeletonNode->endListener = [=] (int trackIndex) {
        log("%d end", trackIndex);
        m_isSkeletonSiwtch = false;
    };
    skeletonNode->completeListener = [] (int trackIndex, int loopCount) {
        log("%d complete: %d", trackIndex, loopCount);
    };
    skeletonNode->eventListener = [] (int trackIndex, spEvent* event) {
        log("%d event: %s, %d, %f, %s", trackIndex, event->data->name, event->intValue, event->floatValue, event->stringValue);
    };

    skeletonNode->setPosition(100, 100);
    this->addChild(skeletonNode);
    //skeletonNode->setAnimation(0, "Event", false);

//this->runAction(Sequence::createWithTwoActions(FadeOut::create(1.5), CallFunc::create([this](){
//        m_pToufaTemp->removeFromParentAndCleanup(true);
//    })));
