[Neo94]

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 .

i hope u understand me
thank you for regarding.

.CPP
TArray last_Online_players;
TArray 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()));
    	
    		
    	}**
