--------- 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. Thanks again for a very helpful post!
