The Compare method is protected, you must use the equality/inequality operators.
friend bool operator==(const FUniqueNetId& Lhs, const FUniqueNetId& Rhs)
{
return Lhs.Compare(Rhs);
}
friend bool operator!=(const FUniqueNetId& Lhs, const FUniqueNetId& Rhs)
{
return !Lhs.Compare(Rhs);
}
Those operators acts on references. So you have to do something like this:
const FUniqueNetId& LocalPlayerUniqueIdRef = *(GetGameInstance()->GetPrimaryPlayerUniqueId().Get());
const FUniqueNetId& InPlayerUniqueIdRef = *(PlayerState->UniqueId.GetUniqueNetId().Get());
bool bIsSamePlayerId = LocalPlayerUniqueIdRef == InPlayerUniqueIdRef;
