    Hi list, i'm in trouble to get data from a SplineData panel.

    spdata=data->GetCustomDataType(PATHDEFORMER_SCALE, CUSTOMDATATYPE_SPLINE);
    if (!spdata)
    {
        GePrint("spdata is null");
        return TRUE;
    }

    Vector punto=spdata->GetPoint(.5);

    spdata is always null, so i wrong to do that.
    What's the method to get wonderful data from a Spline panels?

    I know that my english is very bad, but i hope that someone understand what i mean.

    Best Regards
    Renato T.

    the code that i wrote is this.. replace first line wuth this.

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

    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

    Dwarf,

    your help make my code working but don't initialize anything. Where i can find an example code for that?

    In sdk i don't found anything that help me to use correct this panel.
    Thank

    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.

    i think that i no wrote spline datatype

    i'm a very starter, could you be more precise?

    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
