MarkMaterials Struct Reference

#include <c4d_baselist.h>

Detailed Description

Message struct for the MSG_MULTI_MARKMATERIALS message.
This is an example of how to handle the message:

Bool MyObject::Message(Int32 msg_type, void* msg_data)
{
  switch (msg_type)
  {
    case MSG_MULTI_MARKMATERIALS:
    {
      // 'mat' is the material of my object in the link parameter MATERIAL_ID
      BaseDocument* doc = GetDocument();
      BaseMaterial* mat = data.GetMaterialLink(MATERIAL_ID, doc);
 
      if (MarkMaterials::IsTranslation(msg_data)) // Material translation, update my link if necessary
      {
        MarkMaterials* mm = static_cast<MarkMaterials*>(msg_data);
        if (doc && mm->omat == mat)
        {
          doc->undo.InitUndo(UNDO_CHANGE_SMALL, this);
          data.SetLink(MATERIAL_ID, mm->nmat);
        }
      }
      else // Material marking, mark all my materials
      {
        MarkMaterials::Mark(mat, msg_data);
      }
    }
    break;
  }
 
  return SUPER::Message(msg_type, msg_data);
}

If the material link is stored in a BaseContainer, you can also use the convenience function HandleMaterialInContainer which handles both translation and marking.
