Help - getting individual item info from a editor created scene

[gwald]

Hello again, Happy holidays :)

I'm trying to get individual items from a scene created by the editor. I can load the scene, but I want to move the individual parts in the scene.

        modelRes = h3dAddResource( H3D_ResTypes_SceneGraph, filename, 0 );

        if(modelRes == 0)//failed
        {
            printf("Failed Model: <%s>\n",filename );
            return 1;
        }
h3dutLoadResourcesFromDisk( "." );
    // Add model to scene
    g_model = h3dAddNodes( H3DRootNode, modelRes );

        printf("1 h3dGetResElemCount %d\n", h3dGetResElemCount(modelRes, H3D_ResTypes_SceneGraph    ) );

But it looks like there's nothing there?

int Resource::getElemCount( int elem ) const
{
    H3D_UNUSED_VAR(elem);
    Modules::setError( "Invalid elem in h3dGetResElemCount" );
    return 0;
}

Is it not possible to get nodes from an editor scene?

I noticed in the editor it uses h3dGetNextResource

                int i = 0;
        while( ( i = h3dGetNextResource( H3D_ResTypes_Undefined, i ) ) != 0 )
        {
            printf("h3dGetResName( %d ) %s\n", i, h3dGetResName( i )  );
        }

That gives out a nice list of everything in the scene file:

Using the model's scene files ie models/t1.scene.xml, the ResHandle is 11.

The whole sense ( models/NewScene1.scene.xml reshandle: 5) or individual parts can be use in the scene by using

node = h3dAddNodes( H3DRootNode, reshandleNum );
