Lightmapping - LightMapMaker/Irrlicht

[MikeP]

Ok, after my lame attempts at getting lightmaps with 3DS and my3D, I tried another thing that I found on this forum, LightMapMaker irrlicht plugin by dhenton@users.sourceforge.net.
It allows to export in *.irr in LightmapMaker. Then there's a loader the author provided with a nice working example compiled.
And AGAIN this is outdated and doesn't work with current Irrlicht.
When compiling his example code under C::B 8.02 I'm getting this :

D:\Game Studio\irrlicht-1.4\projects\LMM_test\LMMLoader.h||In constructor `irr::scene::CLMMLoader::Surface::Surface()':|

||=== Build finished: 5 errors, 1 warnings ===|

(there was also the famous error with the eventreceiver but since I've seen it 100 times already I corrected it)

the obsolete binding was this :

Code: Select all

				for (j=0;j<verts.size();j++)
				{
					printf("vert %d\n",j);
					verts[j].PrintOut();

				}

that I turned in this :

for (int j=0;j<verts.size();j++)
{
printf("vert %d\n",j);
verts[j].PrintOut();

}

but I have no clue about the other error, in LMMLoader.h it's this :

Code: Select all

class CLMMLoader : public IMeshLoader
	{
	public:

		//! constructor
		CLMMLoader(video::IVideoDriver* driver);

		//! destructor
		virtual ~CLMMLoader();

		//! returns true if the file maybe is able to be loaded by this class
		//! based on the file extension (e.g. ".cob")
		virtual bool isALoadableFileExtension(const c8* fileName);

		//! creates/loads an animated mesh from the file.
		//! \return Pointer to the created mesh. Returns 0 if loading failed.
		//! If you no longer need the mesh, you should call IAnimatedMesh::drop().
		//! See IUnknown::drop() for more information.
		virtual IAnimatedMesh* createMesh(irr::io::IReadFile* file);

and in Irrlicht's IMeshLoader.h this :

Code: Select all

class IMeshLoader : public virtual IReferenceCounted
{
public:

	//! destructor
	virtual ~IMeshLoader() {}

	//! Returns true if the file maybe is able to be loaded by this class.
	/** This decision should be based only on the file extension (e.g. ".cob") */
	virtual bool isALoadableFileExtension(const c8* fileName) const = 0;

	//! Creates/loads an animated mesh from the file.
	/** \return Pointer to the created mesh. Returns 0 if loading failed.
	If you no longer need the mesh, you should call IAnimatedMesh::drop().
	See IReferenceCounted::drop() for more information. */
	virtual IAnimatedMesh* createMesh(io::IReadFile* file) = 0;
};


} // end namespace scene
} // end namespace irr

and the call in the cpp is :

Code: Select all

scene::CLMMLoader* lLoader = new scene::CLMMLoader(driver);

what shall I do to make that loader work

Is anyone actually using Lightmapmaker with irrlicht or is everyone using Blitz3D ?

      //! returns true if the file maybe is able to be loaded by this class

      //! See IUnknown::drop() for more information.
      virtual IAnimatedMesh* createMesh(irr::io::IReadFile* file); 

to

Code: Select all

class CLMMLoader : public IMeshLoader
   {
   public:

      //! constructor
      CLMMLoader(video::IVideoDriver* driver);

      //! destructor
      virtual ~CLMMLoader();

      //! returns true if the file maybe is able to be loaded by this class
      //! based on the file extension (e.g. ".cob")
      virtual bool isALoadableFileExtension(const c8* fileName) const;

      //! creates/loads an animated mesh from the file.
      //! \return Pointer to the created mesh. Returns 0 if loading failed.
      //! If you no longer need the mesh, you should call IAnimatedMesh::drop().
      //! See IUnknown::drop() for more information.
      virtual IAnimatedMesh* createMesh(irr::io::IReadFile* file); 

You forgot the const after isALoadableFileExtension(const c8* fileName);


For the record, switching to Ogre will just make things more difficult on you if you're missing things like that.

For the record, switching to Ogre will just make things more difficult on you if you're missing things like that.

That's what I'm doing sorry :/

It's driving me crazy not having up to date tutorials and examples and having to debug old crap just to fit the 1.4 before I can even get how this or that features works is a pain in the ass I don't wanna face anymore.
And seeing how big is the content made for, with and towards Ogre, fresh one, will definitely make things easier. Just compare the Wikis
Same for the forums.. the max number logged was 272 in Feb.2007 here. Since i'm there I never saw more than 8-10 registered user at a time. bigger community makes it easier to get help too.

Well, good thing. Chances are you'll need a lot of help. I had a harder time getting Ogre set up than Irrlicht.

Actually, I've never been able to get Ogre set up.

Mostly laziness and refusal to download a billion things from a billion sites to get it to work with C::B or something like that.
