Hi ...

Will it do my friend?

void GetAllCameras(AtomArray *oCams,BaseObject *oCam)
{
     if(oCam)
     {
          if(oCam->GetType()==Ocamera)
               oCams->Append(oCam);

if(oCam->GetDown())
               GetAllCameras(oCams,oCam->GetDown());
          if(oCam->GetNext())
               GetAllCameras(oCams,oCam->GetNext());
     }
}

LONG GetAllCameras(AtomArray *oCams)
{
     if(!oCams) return 0;

BaseDocument *doc=GetActiveDocument();
     BaseObject *obj=doc->GetFirstObject();
     if(obj)
     {
          GetAllCameras(oCams,obj);
     }

return oCams->GetCount();
}

You need to call the second function and then all the cameras will be in the AtomArray parameter you passed ...
If you just want the count only ... you don't need that parameter ...
For example ... you are using a command plugin and you got a button ... Then your command function will be ... like below ...

Bool dlgYourPlugin::Command(LONG id,const BaseContainer &msg;)
{
     BaseDocument *doc=GetActiveDocument();
     switch(id)
     {
     case BTN_DISPLAY_CAMERAS:
          {
               LONG i;
               AtomArray *oCameras=AtomArray::Alloc();
               LONG lCamCnt=GetAllCameras(oCameras);
               for(i=0;i<lCamCnt;i++)
               {
                    BaseObject *obj=(BaseObject * )oCameras->GetIndex(i);
                    MessageDialog(obj->GetName());
               }
               AtomArray::Free(oCameras);
          }
          break;
     }
}

Wishing it can help you in a way ...

Hi ...
I also tested before I post ... 🙂 ... and it worked ...
So pls ... be sure to allocate the AtomArray before you pass to the LONG GetAllCameras(AtomArray *oCams) function ...
AtomArray *varX=AtomArray::Alloc();
LONG l=GetAllCameras(varX);
MessageDialog(LongToString(l)+ " cameras!");
 
It'll be more helpful if you can show me your code lines?
Regards ...

this is my some codes: to get snapshoot (viewport and cameras) when the plugin be clicked and launch my operation windonws
