【已解决】对于cocos2dx 3.0rc1重力感应的问题

Cocos2d-x
#1

为何 【class GameLayer : public cocos2d::Layer 】中继承虚函数 void onAcceleration(Acceleration* acc, Event* unused_event);会报错

1>e:\studycocos2dx3.0rc1\game\classes\helloworldscene.h(45): error C2061: 语法错误: 标识符“Acceleration” (…\Classes\HelloWorldScene.cpp)
1>e:\studycocos2dx3.0rc1\game\classes\helloworldscene.h(45): error C2061: 语法错误: 标识符“Acceleration” (…\Classes\AppDelegate.cpp)

#2

Acceleration加个命名空间：cocos2d:: Acceleration

#3

好吧，我忘记加 USING_NS_CC; 难怪。。谢了
