C++ Emit doesn't fill prop pointers correctly for lambda/delegate listeners #15

Open getnamo opened 3 years ago

getnamo commented 3 years ago

If we use the BP execGESEmitEventOneParam our emit data will already contain the correct prop pointers when the event gets processed.

However if we emit directly from c++ i.e. via FGESHandler::DefaultHandler()->EmitEvent(EmitData); this won't necessarily fill the prop pointer if your receiver is a lambda or delegate.

Needs a fill/conversion step before we handle the emit

Only remaining non-working pair is c++ struct to bp. All other pairs work. Note added in readme, merging current branch until more dev time is found.
