Can't subscribe to event in different class

My project looks like this:

I have a MainApplication:

[code]…

URHO3D_DEFINE_APPLICATION_MAIN(MainProcessor)

MainProcessor::MainProcessor(Context* context) :
Base(context)
{
// Set up MainProcessor
}
…[/code]

a custom scene class:

[code]…

namespace Urho3D
{
class Node;
class Scene;
class Sprite;
}

using namespace Urho3D;

class CustomScene {
public:
CustomScene(SharedPtr scene, ResourceCache* cache, KinectProcessor* kinectProcessor, SharedPtrUrho3D::Image chromaKeyImage) {
scene_ = scene;
cache_ = cache;
// Set up the rest
};

protected:
SharedPtr scene_;
SharedPtr cache_;
KinectProcessor* kinectProcessor_;
SharedPtr backgroundMaterial_;
SharedPtrUrho3D::Image chromaKeyImage_;
};
…[/code]

and a custom scene:

[code]…

namespace Urho3D
{
class Node;
class Scene;
}

using namespace Urho3D;

class UnderwaterScene : public CustomScene {
public:
UnderwaterScene(SharedPtr scene, ResourceCache* cache, KinectProcessor* kinectProcessor, SharedPtrUrho3D::Image chromaKeyImage)
: CustomScene(scene, cache, kinectProcessor, chromaKeyImage)
{
// Set up custom scene
scene_->SubscribeToEvent(E_ANIMATIONFINISHED, URHO3D_HANDLER(UnderwaterScene, HandleAnimationFinished));
};

   void HandleAnimationFinished(StringHash eventType, VariantMap& eventData)

{
// Do stuff
}

…[/code]

Problem is, I can’t subscribe to events using SubscribeToEvent() in the UnderwaterScene class. I get the following errors:

[quote]Severity Code Description Project File Line Suppression State
Error C2664 ‘Urho3D::EventHandlerImpl::EventHandlerImpl(Urho3D::EventHandlerImpl &&)’: cannot convert argument 1 from ‘void (__cdecl UnderwaterScene::* const )(Urho3D::StringHash,Urho3D::VariantMap &)’ to ‘UnderwaterScene *’ ChromaProject c:\urho3d\build\include\urho3d\Core\Object.h 319[/quote]
and

Error C2440 ‘static_cast’: cannot convert from 'Urho3D::Object ?*const ’ to ‘UnderwaterScene *?’ ChromaProject c:\urho3d\build\include\urho3d\Core\Object.h 319[/quote]

What am I doing wrong?

You must inherit Object to send & receive events.
