Understanding POL source

Hey,
I am still trying to understand POL source code. I have found this:
Code: Select all
bool NPC::send_event( Bscript::BObjectImp* event )
{
if (ex != NULL)
{
if (ex->os_module->signal_event( event ))
return true;
}
Bscript::BObject bo( event );
return false;
}
Basically, if the NPC has an AI (ex != NULL) the event is sent to the script and true is returned. If not, false is returned but what "Bscript::BObject bo( event )" does?

Not really sure, since I didn't looked into calling code.
It looks like that the event parameter is an owing pointer, thus the function needs to transfer the ownership or destroy the pointer. Otherwise it would result in a memory leak.
The creation of the bobject is just for that purpose destroying the pointer, if you look at the deconstructor you should see a delete.

Thank you for your answer!
It sounds complicated to me, but I think I've understood it
Anyway, BObject's deconstructor seems to be empty.
That's weird, because I am trying to debug a trace that leads me exactly there.
