Hi everybody,


I started to build a Guild-Mod with networking. The Client-To-Server Connections works properly and i already can create a Guild, but when i am trying to Check, if 
i am in a Guild, i either Receive no answer from the return or i get an Exception, when i directly send the Answer back to the Client.

 

I need a check, if a player is in a Guild in the PlayerLoggedInEvent and when opening a Gui.

Both lead to the same Exception and when i comment the line "ModMain.NETWORK.sendTo(nwm, serverPlayer);" the program don´t throw the Exception, but simpy dont work.

 

How can in "answer" to a NetworkMessage?

 

NetworkMessage: 

package mods.network;

import io.netty.buffer.ByteBuf;
import net.minecraftforge.fml.common.network.ByteBufUtils;
import net.minecraftforge.fml.common.network.simpleimpl.IMessage;

public class NetworkMessage  implements IMessage {
	  public NetworkMessage(){
		  System.out.println("Networkmessage Recognized");
	  }

	  public String json = "";
	  
	  
	  public NetworkMessage(String toSend) {
	    this.json = toSend;
	  }

  @Override
  public void fromBytes(ByteBuf buf) {
	  json = ByteBufUtils.readUTF8String(buf);
  }

  @Override
  public void toBytes(ByteBuf buf) {
      ByteBufUtils.writeUTF8String(buf, json);
  }
 }

 

NetworkMessageHandler: 

package mods.network;

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;

import mods.ModMain;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraftforge.fml.common.network.simpleimpl.IMessage;
import net.minecraftforge.fml.common.network.simpleimpl.IMessageHandler;
import net.minecraftforge.fml.common.network.simpleimpl.MessageContext;

public class NetworkMessageHandler implements IMessageHandler<NetworkMessage, IMessage> {
	  @Override public IMessage onMessage(NetworkMessage message, MessageContext ctx) {
	    EntityPlayerMP serverPlayer = ctx.getServerHandler().player;
	    	    
	    NetworkObject na = (new Gson()).fromJson(message.json,new TypeToken<NetworkObject>() {}.getType());
		NetworkObject answer = new NetworkObject();
		NetworkMessage nwm = null;
		    switch(na.action)
		    {
		    	case NetworkActions.GuildCheck:
		    		answer.action = NetworkActions.GuildCheckAnswer;
		    		answer.values = "Testgilde";
		    		
		    		System.out.println("[Server] CURRENT GUILD: "+na.values);
		    		nwm = new NetworkMessage((new Gson()).toJson(answer));
		    		ModMain.NETWORK.sendTo(nwm, serverPlayer); 
		    		break;
		    	case NetworkActions.GuildCheckAnswer:
		    		System.out.println("[Client] CURRENT GUILD: "+na.values);
		    		break;
		    	default:
		    }
	    
	    return nwm;
	  }
	}

 

NetworkObject: 

public class NetworkObject {
	public int action = -1;
	public String values = "";
}

 

Initiating Call: 

NetworkObject answer = new NetworkObject();
answer.action = NetworkActions.GuildCheck;			
ModMain.NETWORK.sendToServer(new NetworkMessage((new Gson()).toJson(answer)));

 

Register: 

@Mod.EventHandler
public void preInit(FMLPreInitializationEvent event) {
	System.out.println(name + " is loading!");

	// Networkpackets
	NETWORK.registerMessage(NetworkMessageHandler.class, NetworkMessage.class, 0, Side.SERVER);
	NETWORK.registerMessage(NetworkMessageHandler.class, NetworkMessage.class, 0, Side.CLIENT);
}
