How can I use custom enums in replicated functions?

Byorun_1 · May 7, 2014, 7:24pm

I am trying to replicate a function that has a custom enum type as parameter.

.h

UFUNCTION(Server, Reliable, WithValidation)
void ServerSetTeam(TEnumAsByte<EKaoriGameTeam::Type> NewTeam);

.cpp

bool AKaoriTeam::ServerSetTeam_Validate(TEnumAsByte<EKaoriGameTeam::Type>  NewTeam)
{
	return true;
}

void AKaoriTeam::ServerSetTeam_Implementation(TEnumAsByte<EKaoriGameTeam::Type>  NewTeam)
{
	Team = NewTeam;
}

If I try to build my game I get the following error

19> …\KaoriTeam.cpp(48): error C2511: ‘bool AKaoriTeam::ServerSetTeam_Validate(TEnumAsByte)’ : overloaded member function not found in ‘AKaoriTeam’
19> …\KaoriTeam.h(15) : see declaration of ‘AKaoriTeam’
19> …\KaoriTeam.cpp(53): error C2511: ‘void AKaoriTeam::ServerSetTeam_Implementation(TEnumAsByte)’ : overloaded member function not found in ‘AKaoriTeam’
19> …\KaoriTeam.h(15) : see declaration of ‘AKaoriTeam’
19> …\Kaori.generated.inl(116): error C2511: ‘void AKaoriTeam::ServerSetTeam(EKaoriGameTeam::Type)’ : overloaded member function not found in ‘AKaoriTeam’
19> …\KaoriTeam.h(15) : see declaration of ‘AKaoriTeam’

If I only change the parameter from TEnumAsByte to lets say uint32 everything works fine.

EDIT: Ok I removed the TEnumAsByte and only use EKaoriGameTeam::Type now it works but at some point the compiler told me that I should use TEnumAsByte if I want to use my Enum, When do I need TEnumAsByte and when not?

Maybe that is not really a network error but a UBT error?

19> …\KaoriTeam.h(15) : see declaration of ‘AKaoriTeam’ 19> …\Kaori.generated.inl(116): error C2511: ‘void AKaoriTeam::ServerSetTeam(EKaoriGameTeam::Type)’ : overloaded member function not found in ‘AKaoriTeam’

there is no TEnumAsByte<> only EKaoriGameTeam::Type

This sounds like something networking team should look at and see if TEnumAsByte can be supported properly.

You should be using TEnumAsByte wherever possible as it is the Blueprint-friendly type and is a really nice class. Check out EnumAsByte.h !

My favorite is:

/** Get the value */
TEnum GetValue() const
{
	return TEnum(Value);
}

You have a byte but you also have type protection and custom operator equality
