ISceneUserDataSerializer is a struct? (apparently)

[Paradigm^]

Hello (again).

I found I had exactly the same problem as mentioned in this thread and with a bit of searching and clarifying I now know what I should be doing. Having come to compile time, I get a very odd error though:

Code: Select all

In file included from engine.cpp:3:
mapserialiser.h:9: error: invalid use of undefined type `struct irr::scene::ISceneUserDataSerializer'
../irrlicht-1.1/include/ISceneManager.h:111: error: forward declaration of `struct irr::scene::ISceneUserDataSerializer'

As far as the documentation, the source code, and I know, ISceneUserDataSerializer is definitely not a struct. It's an interface. All I've tried to do is implement this, but it's not happy, and I don't know why. Here's my .h file:

Code: Select all

using namespace irr;

using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

class MapSerialiser : public ISceneUserDataSerializer{
public:
	MapSerialiser(ISceneManager*, IMetaTriangleSelector*, IMetaTriangleSelector*);
	virtual IAttributes* createUserData(ISceneNode*);
	virtual void OnReadUserData(ISceneNode*, IAttributes*);

private:
	ISceneManager* sm;
	IMetaTriangleSelector* mp;
	IMetaTriangleSelector* mpp;
};

Is something wrong with it, or is the problem elsewhere? Thought I'd put this question here rather than in the other thread because I have a feeling it's a programming error rather than something serious.

Cheers!

It looks like you need to include ISceneUserDataSerializer.h. Your header shows no includes, but at the very least it should have the following near the top...

Code: Select all

#include <Irrlicht.h>

// need to include this explicitly because someone forgot to put it in the global header Irrlicht.h
#include <ISceneUserDataSerializer.h>

Aha! Thanks. All my #includes are in the .cpp files, which is why you don't see them in the .h file. Adding a #include for ISceneUserDataSerializer fixed it. Well done to whoever it is that forgot to add it in irrlicht.h, it's had me confused for the past two hours :p

Cheers!
