Hello,

I want to color a null object and a spline that the user links into my expression. I tried like this (for the null object) :

  
Vector Target_Color(1,1,0);  
Real Target_Radius = 25.0;  
  
BaseObject     *SC_TargetObj = tag->GetData().GetObjectLink(TARGET_OBJ, doc);  
  
SC_TargetObj->GetDataInstance()->SetLong(NULLOBJECT_DISPLAY, NULLOBJECT_DISPLAY_CIRCLE);  
SC_TargetObj->GetDataInstance()->SetReal(NULLOBJECT_RADIUS, Target_Radius);  
SC_TargetObj->GetDataInstance()->SetLong(ID_BASEOBJECT_USECOLOR, ID_BASEOBJECT_USECOLOR_ALWAYS);  
SC_TargetObj->GetDataInstance()->SetVector(ID_BASEOBJECT_COLOR, Target_Color);

Setting NULLOBJECT_DISPLAY and NULLOBJECT_RADIUS works fine. The null object gets a cirle with the appropriate radius. But with ID_BASEOBJECT_USECOLOR and ID_BASEOBJECT_COLOR, nothing happens. No error message, but also no color.

What's my mistake? Thanks for any help.

Greetings,
Jack

Is this the right way to put data into ID_BASEOBJECT_COLOR, anyway? How would you do this? Is there any example code in one of the example plugins?

Try this instead for the last two values:

SC_TargetObj->SetParameter(DescID(ID_BASEOBJECT_USECOLOR),GeData(ID_BASEOBJECT_USECOLOR_ALWAYS),0L);
SC_TargetObj->SetParameter(DescID(ID_BASEOBJECT_COLOR),GeData(Target_Color),0L);

And that's totally correct.
