Hello Guys i try to send a message from client to server ,when i sent a message from a client i received that separated, each client have a array , but i don’t want this i want common array for clients .
on the screenshot u see i have 2 separate client but my array show me online player : 1 but it should be 2 !
i hope u understand me 
thank you for regarding.
.CPP
TArray<int32> last_Online_players;
TArray<int32> Client_ID_on_status_checking = { 1 };
void UChecking_Offline::SetSomeBool(const TArray<int32>& awdd)
{
}
bool UChecking_Offline::ServerSetSomeBool_Validate(const TArray<int32>& awdd)
{
return true;
}
void UChecking_Offline::ServerSetSomeBool_Implementation(const TArray<int32>& awdd)
{
if (last_Online_players.Find(Client_ID)) last_Online_players.Add(Client_ID);
SetSomeBool(last_Online_players);
}
void UChecking_Offline::Clinet_Joined()
{
void ServerSetSomeBool_Implementation(const TArray<int32>& awdd);
{
if (last_Online_players.Find(Client_ID)) last_Online_players.Add(Client_ID);
FString NewString = FString::FromInt(last_Online_players.Num());
UE_LOG(LogTemp, Log, TEXT("online players: %s"), *NewString);
GEngine->AddOnScreenDebugMessage(-1, 0.5f, FColor::Yellow, "online players :"+ FString::FromInt(last_Online_players.Num()));
}
