[Bf-python] Effect module : New function modified

[jean-michel soler]

Hi,
the Effect.New function  return  currently (2.40alpha) None .
But it could return a  particule effect, and, in the same time, add this 
effect to a  mesh object pointed by its name .

/* Function:              
M_Effect_New                                       */
/* Python equivalent:     
Blender.Effect.New                                 */
/*    args :    string,    mesh object 
name                                        */
/*     in  :      create and add a new particule effect to the given 
mesh        */
/*    return  : an particule 
effect                                             */ 
/*****************************************************************************/
PyObject *M_Effect_New( PyObject * self, PyObject * args )
{
    void BLI_addtail(struct ListBase *listbase, void *vlink);
    struct Effect *add_effect(int type);

    Object *ob;

    BPy_Effect *pyeffect;
    Effect *bleffect = 0;
    int type = -1;
    char *name = NULL;

    /*Py_INCREF( Py_None );
    return Py_None;*/

    if( !PyArg_ParseTuple( args, "s", &name ) )
        return ( EXPP_ReturnPyObjError( PyExc_TypeError,
                        "expected string : mesh object name )" ) );
   
    bleffect = add_effect( EFF_PARTICLE );
   
    if( bleffect == NULL )
        return ( EXPP_ReturnPyObjError( PyExc_RuntimeError,
                        "couldn't create Effect Data in Blender" ) );

    ob = G.main->object.first;
    while( ob ) {
           if( !strcmp( name, ob->id.name + 2 ) ) {
                if( ob->type != OB_MESH )
                return ( EXPP_ReturnPyObjError( PyExc_TypeError,
                   "couldn't create a particule effect on object of this 
kind . Use an object mesh's name " ) );
                BLI_addtail(&ob->effect, bleffect);
             }
             ob = ob->id.next;
          }

    pyeffect = ( BPy_Effect * ) PyObject_NEW( BPy_Effect, &Effect_Type );

    if( pyeffect == NULL )
        return ( EXPP_ReturnPyObjError( PyExc_MemoryError,
                        "couldn't create Effect Data object" ) );

    pyeffect->effect = bleffect;

    return ( PyObject * ) pyeffect;
}
