Hey Guys,

I am working on an objectdata-plugin. I create several objects (NURBS) in GetVirtualObjects and I want to make them transparent. So I do something like this:

  
BaseContainer *bc = obj->GetDataInstance();  
bc->SetLong(ID_BASEOBJECT_VISIBILITY_EDITOR, editor);  
bc->SetLong(ID_BASEOBJECT_VISIBILITY_RENDER, render);  
bc->SetBool(ID_BASEOBJECT_XRAY, xray);

But x-ray does not get set. Any idea why?

The only place it seems to work is inside of the Draw() function.

DRAWRESULT MyObject::Draw(BaseObject *op, DRAWPASS drawpass, BaseDraw *bd, BaseDrawHelp *bh)  
{  
  
  //code that draws the object here  
  
  ....  
  
  //Get the state of the xray option  
  GeData d;  
  op->GetParameter(DescID(ID_BASEOBJECT_XRAY), d, DESCFLAGS_GET_0);  
  LONG xstate = d.GetLong();  
  GePrint(LongToString(xstate));  
  
  
  //Enable the Xray option  
  op->SetParameter(DescID(ID_BASEOBJECT_XRAY), GeData(TRUE), DESCFLAGS_SET_0);  
  EventAdd();  
  
  return DRAWRESULT_OK;  
}

Hey Scott,

Thank you for your replay. It works but the problem is, that the hole object would be transparent. I only want a special object.

I get an other method, but here I must convert my NURB object and that is not very fine...

  
          bd->DrawPolygonObject(bh, res, DRAWOBJECT_XRAY_ON, op, green);

Please check the BaseObject::SetColorProperties() function. It's used to set object colors and X-Ray.

Does not work.

ObjectColorProperties ocp;  
      ocp.usecolor =    ID_BASEOBJECT_USECOLOR_ALWAYS;  
      ocp.xray =            TRUE;  
      ocp.color =            Vector(0.0,1.0,0.0); //green  
      obj->SetColorProperties(&ocp);

You're setting it on the object you're generating. Set it on the generator object itself and it will work. I.e.:

  
  
BaseObject* MyObjectDataPlugin::GetVirtualObjects(BaseObject *op, HierarchyHelp *hh)   
{   
//.... do other stuff   
ObjectColorProperties ocp;   
        ocp.usecolor =    ID_BASEOBJECT_USECOLOR_ALWAYS;   
        ocp.xray =            TRUE;   
        ocp.color =            Vector(0.0,1.0,0.0); //green   
        op->SetColorProperties(&ocp;);    // <------ uses 'op' not your generated object   
}

Hey spedler,

Thank you but I want to use it on an object I generate and not on a the hole generator. Only a part of it.

If anyone run into the same problem.. you have to set the OBJECT_USECACHECOLOR flag when registering the object to avoid that the color properties get overwritten by the generator.
