Why do I get a LNK error for GetLifetimeReplicatedProps() in a class that does not use that function?
Even stranger, if I ignore the error and just compile again it says:
1> Compiling game modules for hot reload
1> Target is up to date.
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
Is the second compile really a successful compile?
I had this problem too,in my case it happens when an UPROPERTY has the “REPLICATED” flag on it.
How To Fix It:
In Your .h :
In Your .cpp :
void AYourClassName::GetLifetimeReplicatedProps( TArray< FLifetimeProperty > & OutLifetimeProps ) const
Hope this solves your problem. I Kinda guess this function is needed for replication.
