Did you create the spline and store it? If it isn't created it cannot be accessed. I do this in the Init() function. The rest of your code seemed fine.

// Set Spline Data
GeData d ( CUSTOMDATATYPE_SPLINE, DEFAULTVALUE );
SplineData *p = (SplineData* ) d.GetCustomDataType( CUSTOMDATATYPE_SPLINE );
if ( p )
{
p->MakeLinearSpline( 2 );
p->InsertKnot( 0.25, 0.0, TRUE );
p->InsertKnot( 0.75, 1.0, TRUE );
p->SetRound( 0.0 );
}
data->SetData( YOUR_PARAMETER_ID, d );

Darf, thank, now cinema is not crashing but, how i can get y value from x value?

i tried with spline->GetPoint(real); but it return a 0,0,0 vector.

thanks for your precious infos

Sorry for not getting back, the forum must forward emails to the old bhodinut account.

The code I offered works for initializing the the spline data ( that is how NICKL works ). Can you create an example project and post it?

Erhmm... I have never been considered a dwarf before. It's darf, no matter what certain MAXON employees say. 9-)

Hi Darf, thanks.

here the code for Init:

GeData d ( CUSTOMDATATYPE_SPLINE, DEFAULTVALUE );
     SplineData *p = (SplineData* ) d.GetCustomDataType( CUSTOMDATATYPE_SPLINE );
     if ( p )
     {
          p->MakeLinearSpline( 2 );
          p->InsertKnot( 0.0, 1.0, TRUE );
          p->InsertKnot( 1.0, 1.0, TRUE );
          p->SetRound( 0.0 );
     }
     data->SetData( PATHDEFORMER_SCALE, d );

and here i read data:

SplineData *spdata=NULL;
spdata=(SplineData* ) data->GetCustomDataType(PATHDEFORMER_SCALE, CUSTOMDATATYPE_SPLINE);

and..

spliney=spdata->GetPoint(o);
to get yspline value from (0<o<1)

-----------------------------------------
it work, but when i try to reset splinedata from the editor, all points disappear.. i thought that a precedent initialization was usefull to set default value.

Any help?

Thanks
Renato

Spline Datatypes reset to no points. I am not sure if there is way to get around that unless you write your spline datatype.

Ok, now it work like i need.

Testing...

Uhh, -1, is that a default value I don;t know about? That value is the number of points to allocate me thinks. I am not sure. I offered the only code for the C4D internal spline datatype. The custom spline datatype I was referrring to would be completely written by you. The internal spline type is very limited IMHO.

Darf,

With this my spline was initialized with 2 point and make a corretc default curve.

Anyway, the probs is my english. For me is hard to understand.

Thanks for your help
