3、学习重点

1、grossini->runAction(Sequence::create(MoveBy::create(1,Vec2(150,0)),CallFuncN::create(CC_CALLBACK_1(LogicTest::bugMe,this)),NULL));
2、director->getActionManager()->addAction(action,true); schedule(CC_SCHEDULE_SELECTOR(PauseTest::unpause),3);
3、unschedule(CC_SCHEDULE_SELECTOR(PauseTest::unpause)); director->getActionManager()->resumeTarget(node);
4、auto pCallback = CallFunc::create(CC_CALLBACK_0(StopActionTest::stopAction,this));
5、sprite->stopAllActionsByTag(kTagSequence);
一个tag值可以设置多个对象，并且，getTag时返回所有对象。
