Custom SceneNodeAnimator don't want to work -.-

[cookie]

Hiho, I've got a problem with my custom animator... I'm from the german Irrlicht board but the people there don't want to help me so I come to you and hope you will be better :O and sorry for my bad englisch

So...I wrote my own animator class, so far so good but when I write something for the class into my *.cpp file I get this Debug-Message:

obj\Debug\Engine_Particle.o||In function `_ZN3irr4core12irrAllocatorIcE15internal_deleteEPv':|
\include\IAttributeExchangingObject.h:(.text+0x7b)||undefined reference to `vtable for CSceneNodeEmitterStop'|
\Engine_Particle.o||In function `_ZN21CSceneNodeEmitterStopC1EPN3irr5scene24IParticleSystemSceneNodeEi':|

\Engine_Particle.cpp|4|undefined reference to `vtable for CSceneNodeEmitterStop'|
\Engine_Particle.cpp|4|undefined reference to `vtable for CSceneNodeEmitterStop'|
||=== Build finished: 5 errors, 0 warnings ===|

I don't have any idea what I should do...

And here is the Sourcecode of my Animator-class

Header Filei:

Code: Select all

#ifndef ENGINE_PARTICLE_H_INCLUDED
#define ENGINE_PARTICLE_H_INCLUDED

#include <irrlicht.h>
#include "Engine_Globals.h"





using namespace irr;

class CSceneNodeEmitterStop : public ISceneNodeAnimator
{
	public:

		//! constructor
		CSceneNodeEmitterStop(int ms);

		//! destructor
		//virtual ~CSceneNodeEmitterStop();

		//! animates a scene node
		virtual void animateNode(ISceneNode* node, u32 timeMs);

		//! Writes attributes of the scene node animator.
		virtual void serializeAttributes(io::IAttributes* out, io::SAttributeReadWriteOptions* options=0) const;

		//! Reads attributes of the scene node animator.
		virtual void deserializeAttributes(io::IAttributes* in, io::SAttributeReadWriteOptions* options=0);

		//! Returns type of the scene node animator
		virtual ESCENE_NODE_ANIMATOR_TYPE getType() const { return ESNAT_UNKNOWN; }

		//! Creates a clone of this animator.
		/** Please note that you will have to drop
		(IReferenceCounted::drop()) the returned pointer after calling
		this. */
		virtual ISceneNodeAnimator* createClone(ISceneNode* node, ISceneManager* newManager=0);

	private:
              int ms;
};

#endif // ENGINE_PARTICLE_H_INCLUDED

CPP File:

Code: Select all

#include "Engine_Particle.h"

CSceneNodeEmitterStop::CSceneNodeEmitterStop(int ms)
 {
 }

Without this lines in the CPP File the program starts correctly, but with this lines I get this damn Error which I wrote at the top of my super-sweet-english-skilled post

I hope you can help me, thx.

You have to implement all pure virtual methods. You only provided some method declarations and a constructor, that's not enough.

uh...could you explain me what you mean? I didn't understand this.

Thanks

You have to give the actual implementations (the function bodies) of the previously only as "=0" defined methods from the abstract interfaces. Please read a book about abstract classes and (pure) virtual methods, and other nice features of OOP and C++. This is definitely a must to get into touch with Irrlicht.

You have functions which are declared but have no code.
In your CPP file you must implement all of the functions which you have declared in your H file. Currently you have only implemented the constructor.

Fill the other stub functions in your CPP file, like so:

Code: Select all

void CSceneNodeEmitterStop::animateNode(ISceneNode* node, u32 timeMs)
{

}

edit: Hybrid beat me to it

Read through this quick tutorial up to the polymorphism section, it will help a lot:

AAAH thank you now it works!
Ok and now I'll learn something about OOP
