Note that you don't have to do this in the Draw() method. You want to do this in the MouseInput() method. But you should still store the cursor coordinates in GetCursorInfo() to use there.

Also, don't forget to call EventAdd() after SetActiveObject()!

Perfect.. Thanks Robert. I wish I could email you a beer or something. You really ought to be paid for all the help you give.

Thanks again!

Hey Robert, so your method works great. I am able to select objects and use qualifiers to multi select or deselect. One more question. How would i deselect all if the user clicks an area where there is no object behind the cursor?

Thanks,

Shawn

I would check the C4DObjectList for (cnt == 0) or (!cnt) as I do and if this is the case on a mouse click then you call:

if (!cnt)
{
AutoAlloc<AtomArray> atomArray;
if (atomArray)
{
BaseObject* sobj = NULL;
doc->GetActiveObjects(*atomArray, FALSE);
LONG cnt = atomArray->GetCount();
for (LONG i = 0L; i != cnt; ++i)
{
static_cast<BaseObject*>(atomArray->GetIndex(i))->DelBit(BIT_ACTIVE);
}
EventAdd();
}
}

Hmmm..

Well I added what you mentioned and it still does nothing when I click off an object.. Here's my function.. This function is called directly from MouseInput()

  
//SELECT OBJECT

  //Add all objects under the cursor to the Object List  
  AutoAlloc<C4DObjectList> objList;  
  if (!objList)return FALSE;  
  
  if (!SelectionListCreate(doc, NULL, bd, mouseX, mouseY, NULL, objList)) return FALSE;

  if (!objectCount)  
  {  
      GePrint("NO OBJECT");  
      AutoAlloc<AtomArray>  atomArray;  
        
      if (atomArray)

Interestingly... the GePrint() that I added never shows up which must mean that objectCount is never = 0.

Oye.. Tired eyes.

Thanks again Robert.

And you can get rid of the "BaseObject* sobj = NULL;" since I made the DelBit() a one-liner into atomArray instead of getting the object and then calling DelBit().

Already done.. Thanks. I got tired of looking at the "Initialized but not referenced " warning HAHAHA

I'm about to call it a night. I've been at it for a while today. Lots of good progress though. Thanks a lot for your help.
