在使用cocos2dx时，想播放一个动画，结果出现如下异常，想问一下是哪里出问题了

if ( !Layer::init() )
{
return false;
}
auto rootNode = CSLoader::createNode("MainScene.csb");

addChild(rootNode);

auto stonecartoon = CSLoader::createTimeline("MainScence.csb");
rootNode->runAction(stonecartoon);
stonecartoon->gotoFrameAndPlay(60, 90, true);

return true;

}

auto Role = (Sprite*)CSLoader::createNode("RoleWalk.csb");
auto Time = CSLoader::createTimeline("RoleWalk.csb");

Time->gotoFrameAndPlay(140,180,true);
Role->runAction(Time);


this->addChild(Role,1);
