Hello,

How do I get handle to the object created using objects present in a scene or lights or cameras ?

Thanks,
Mister Fuzzy

I'm sorry, I don't quite follow. Are you looking to retrieve an object's ID? It's origin? Position? A limb?

It's been fun: So long, TGC!

Suppose I add a camera, a .x animated object, a limb attached to the object, few lights etc. in my scene.

Now what I want is the DirectX handle for each of them so that I can use C++ and DirectX API code to work upon them ( objects, cameras, lights, limbs etc. ) without using Dark GDK functions any further.

You could probably use sObject struct returned by GetObject(), but at that point you might as well just use straight DirectX or another DX wrapper instead of DarkGDK.

DirectX doesn't have a notion of objects, cameras, etc.

So, how can use DirectX code to manipulate the loaded objects in the scene ?

You can just call dx9 draw functions anywhere in your game loop and it will be presented to screen when dbSync() is called.

So you can create/load models any way you wish.

To manipulate dark basic objects you can do this:
sObject *obj = dbGetObject( id );

There is information on the dbo format somewhere, I think it might come with DBPro.

You can also create cameras and lights and completely bypass DarkGDK, not done this much so can't help there.

@Matty H: This command - dbGetObject( id )

is not listed in the Dark GDK 2.0 chm help file !

Where can I find detail documentation regarding this command ?

Secondly does this command work for all types of objects - 3D meshes, lights, cameras etc.

What is the return data type - sObject ? Is that a C structure ?

Where can I get details about that structure ?

For GDK2 you need to add the command yourself, here are some instructions:

dbGetObject()

There is not much info on the sObject structure, but you can access meshes, limbs and bones etc. Meshes are sMesh[] and limbs are pFrame[] I think.

As far as I know you cant do it with lights or cameras, but I wouldn't be surprised if you could get pointers to GDK lights and cameras through DirectX, or perhaps you could just delete the default GDK light and camera and make your own with the DirectX API.

So, is this an undocumented function that is not formally disclosed by TGC ? Is this function available in Dark GDK 1.0 and Dark Basic Pro by default ? Or do I have to add them manually ?

Can I get the DirectX device handle that Dark GDK ( both 1.0 and 2.0 ) and Dark Basic Pro is using at run-time ?

You can check the DarkGDK header files for all undocumented commands eg..
dbGetDirect3DDevice() returns a pointer to the device.

Not sure about DBPro but they are disclosed for GDK1 in the header files but you will need to add them yourself for GDK2 for now at least.
