Why the box can't move??

When the project runs, I can't see the Box moved(it's still in the sky)
why?

From what I can see...


void createFrameListener(void)
{
mFrameListener=new MyFrameListener(mWindow,mCamera,mworld);
mFrameListener->showDebugOverlay(true);
mRoot->addFrameListener(mFrameListener);

}


You need to add a 'physics' frame listener, so your bodies can actually react to forces applied etc. this is how it's done basically in the SimpleVehicle demo:


void OgreNewtonApplication::createFrameListener()
{
mFrameListener = new OgreNewtonFrameListener( mWindow, mCamera, mSceneMgr, m_World, msnCam, mCar );
mRoot->addFrameListener(mFrameListener);

mNewtonListener = new OgreNewt::BasicFrameListener( mWindow, mSceneMgr, m_World, 60 );
mRoot->addFrameListener(mNewtonListener);
}


Of course this means you'll need a second frame listener, one that will work with OgreNewt, so read the examples

Sorry.
But I change My Code,Add your said.
but it doesn't move.
I see the Example.
I copy my "CreateScene" Code in the First Example.And it still doesn't move.
What do I forget?

My Change Code:

mFrameListener=new MyFrameListener(mWindow,mCamera);
mRoot->addFrameListener(mFrameListener);
FrameListener* newtonlistener= new OgreNewt::BasicFrameListener( mWindow, mSceneMgr, mworld, 60 );
mRoot->addFrameListener(newtonlistener);
