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);
}

Anything that needs an information from the Server, e.g. "Am i in a guild?" or "Did a Guild invite me?"

      [1.20.4] Apply nausea wobble effect to the screen outside Nausea effect

      By chxr · Posted

      So i know for a fact this has been asked before but Render stuff troubles me a little and i didnt find any answer for recent version. I have a custom nausea effect. Currently i add both my nausea effect and the vanilla one for the effect. But the problem is that when I open the inventory, both are listed, while I'd only want mine to show up (both in the inv and on the GUI)   I've arrived to the GameRender (on joined/net/minecraft/client) and also found shaders on client-extra/assets/minecraft/shaders/post and client-extra/assets/minecraft/shaders/program but I'm lost. I understand that its like a regular screen, where I'd render stuff "over" the game depending on data on the server, but If someone could point to the right client and server classes that i can read to see how i can manage this or any tip would be apreciated

      SANGOMA IN Eshowe, Glencoe ╬✯{+2771{066}{7601}✯╬ TRADITIONAL HEALER IN Standerton Phola, Marblehall, Volksrust, Villers

      By honeymuun827 · Posted

      Let me try and help you with love spells, traditional healing, native healing, fortune telling, witchcraft, psychic readings, black magic, voodoo, herbalist healing, or any other service your may desire within the realm of african native healing, the spirits and the ancestors. I am a sangoma and healer. I could help you to connect with the ancestors , interpret dreams, diagnose illness through divination with bones, and help you heal both physical and spiritual illness. We facilitate the deepening of your relationship to the spirit world and the ancestors. Working in partnership with one\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’s ancestors is a gift representing a close link with the spirit realm as a mediator between the worlds.*   Witchdoctors, or sorcerers, are often purveyors of mutis and charms that cause harm to people. we believe that we are here for only one purpose, to heal through love and compassion.*   African people share a common understanding of the importance of ancestors in daily life. When they have lost touch with their ancestors, illness may result or bad luck. Then a traditional healer, or sangoma, is sought out who may prescribe herbs, changes in lifestyle, a career change, or changes in relationships. The client may also be told to perform a ceremony or purification ritual to appease the ancestors.*   Let us solve your problems using powerful African traditional methods. We believe that our ancestors and spirits give us enlightenment, wisdom, divine guidance, enabling us to overcome obstacles holding your life back. Our knowledge has been passed down through centuries, being refined along the way from generation to generation. We believe in the occult, the paranormal, the spirit world, the mystic world.*   The services here are based on the African Tradition Value system/religion,where we believe the ancestors and spirits play a very important role in society. The ancestors and spirits give guidance and counsel in society. They could enable us to see into the future and give solutions to the problems affecting us. We use rituals, divination, spells, chants and prayers to enable us tackle the task before us.*   I have experience in helping and guiding many people from all over the world. My psychic abilities may help you answer and resolve many unanswered questions
