[ANSWERED]Declaration is incompatible

cocos2d-x C++
#1

Hello everyone, I’m pretty new to c++ programming but kinda intermediate programmer in general.

Currently I’m getting this error Declaration is incompatible with “void HelloWorld::functionName( dt)” (declared on your HelloWorld.h.
I already declared the functionName as public inside HelloWorld.h

#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"

#include "SimpleAudioEngine.h"

class HelloWorld : public cocos2d::CCLayer
{
public:
    virtual bool init();  
    static cocos2d::CCScene* scene();
    void functionName(ccTime dt);
    virtual void menuCloseCallback(CCObject* pSender);
    LAYER_NODE_FUNC(HelloWorld);
};
#endif

Then on my HelloWorldScene.cpp

void HelloWorld::functionName(ccTime dt)
{

}

The functionName on HelloWorldScene.cpp gets the wavy red line thingy beneath it indicating the error.

#2

Nevermind I found the solution. For those who haven’t figure this out yet add using namespace cocos2d on HelloWorld.h.
