helleword.h文件中加如下头文件和命名空间
#include “cocostudio/CocoStudio.h”
using namespace cocostudio::timeline;
helloword.cpp文件的onEnter函数中加入从C:\cocos2d-x-3.3\cocos2d-x-3.3\tests\cpp-tests\Classes\ExtensionsTest\CocoStudioActionTimelineTest中拷贝的加载csb文件的方法，并把C:\cocos2d-x-3.3\cocos2d-x-3.3\tests\cpp-tests\Resources\ActionTimeline文件夹拷贝到Resources下
void HelloWorld::onEnter()
{
Layer::onEnter();
Node* node = CSLoader::createNode("ActionTimeline/DemoPlayer.csb");
ActionTimeline* action = CSLoader::createTimeline("ActionTimeline/DemoPlayer.csb");
node->runAction(action);
action->gotoFrameAndPlay(41, action->getDuration(), true);
node->setScale(0.1f);
node->setPosition(100,100);
addChild(node);
}
