求助: Frame event为什么没用

Studio
#1

如题：我调试3.7的demo 也没用。。压根没用啊 什么情况

#2

那个用不了 你要用帧监听 就好了

#3 
auto rootNode = CSLoader::createNode("MainScene.csb");

addChild(rootNode);

action = CSLoader::createTimeline("Node.csb");
rootNode->runAction(action);
//action->gotoFrameAndPlay(50,60,true);
action->play("animation2",true);
//action->gotoFrameAndPlay(0, 70, true);
action->setLastFrameCallFunc(CC_CALLBACK_0(HelloWorld::onFrameEvent, this));

rootNode->runAction(EaseBackIn::create(MoveBy::create(3,Vec2(-100,0))));
return true;

}
void HelloWorld::onFrameEvent()
{

CCLOG(“come on baby”);
action->setTimeSpeed(0.1);
}
