I was doing a dummy command for debugging and testing certain funcs , and what I usually do is use

MGlobal::getSelectionListByName("pSphereShape1" , sel );

now it became redundant af , so I came up with a way to get the actual selected mesh and shiet :

    MObjectArray mesh_list;
    MSelectionList sel;
    MGlobal::getActiveSelectionList(sel);
    if( sel.length() == 0)
    {
        MGlobal::displayError("no selection");
        return MS::kFailure;
    }

    MItSelectionList mitsel(sel);

    MObject cur_obj; 

    do
    {
        mitsel.getDependNode(cur_obj);
        if (cur_obj.hasFn(MFn::kMesh) )
            mesh_list.append( cur_obj );
        else if ( cur_obj.hasFn(MFn::kTransform) )
        {

            MFnTransform fntransform( cur_obj );
            for (int i=0 ;i < fntransform.childCount() ;++i )
            {

                if (fntransform.child(i).hasFn(MFn::kMesh))
                    mesh_list.append(fntransform.child(i));
            }

        }
        
        mitsel.next();

    }while(!mitsel.isDone());
