Prefixes

[Andrew2070]

Hi.

 

I have been working on a new protection system mod.

It is essentially a combination of MyTown2 and Factions.

I had a question that i need specifically answered to move on.

 

#1: How do I add prefixes? ex: [Faction_Rank] [Faction] Player: Message

 

Note --> I do have classes for the "Faction" and "Faction_Rank" part.

I just wanted to know how many classes and the methods to add these to chat.

 

If someone could give me a very specific breakdown that would be nice.

(Looking around I don't see any explanation and I would rather learn than just be handed an answer)

(But in this case, i am looking for both an answer and an explanation).

 

Thanks.

You can use EntityPlayer#addPrefix to add a prefix to a player's display name. You'll probably want to do this when EntityJoinWorldEvent is fired for an EntityPlayer.

[Andrew2070]

Could you go into more detail, I haven't done much with Chat other than commands.

It doesn't have anything to do with the chat. Use the EntityJoinWorldEvent and get the EntityPlayer from it and use EntityPlayer#addPrefix.

EntityPlayer#addPrefix takes an ITextComponent, which will be added to the player's display name as a prefix.

 

There are multiple implementations of ITextComponent, but the most commonly used ones are TextComponentTranslation (translates its first argument and then formats it by calling String.format with its other arguments) and TextComponentString (a single string).

 

ITextComponent#getStyle returns the ITextComponent's Style, which can be used to modify the style of the text.

So I don't understand why this won't work:

 

package com.andrew2070.Empires.API.Chat;

import java.util.List;

import com.andrew2070.Empires.entities.Empire.Empire;
import com.andrew2070.Empires.API.commands.CommandsEMP;
import com.andrew2070.Empires.Datasource.EmpiresUniverse;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.ChatComponentTranslation;
import net.minecraftforge.event.ServerChatEvent;

//check player's selected Empire:

public class Prefix {

	public static final Prefix instance = new Prefix();
	
	public static void onServerChatReceivedEvent(ServerChatEvent event) {

		if (event.player != null) {
		
			EntityPlayer player = (EntityPlayer) event.player;

			if (player != null) {

				event.setCanceled(true);

				List players = MinecraftServer.getServer().getConfigurationManager().playerEntityList;

				for (int i = 0; i < + players.size(); i++) {
				
					EntityPlayer target = (EntityPlayer) players.get(i);

					if(target.getDisplayName().contains("Player")) {
					
					String name = player.getDisplayName();
					Empire empire = CommandsEMP.getEmpireFromName(name);
					String chat = "[" + empire + "]" + player.getDisplayName() + event.message;
					target.addChatMessage(new ChatComponentTranslation(chat));
					}
				}
			}
		}
	}


	}
	


	

 

 

What it does is finds players, makes a list of them and then finds each of their "Empire" names.

Then when they chat, it would print [Empire] Player: Message.

 

Isn't working.

 

My main class has this: 

        FMLCommonHandler.instance().bus().register(Prefix.instance);
        MinecraftForge.EVENT_BUS.register(Prefix.instance);

 

[Choonster]

You should read Forge's documentation page on events, it explains that event handler methods must be annotated with @SubscribeEvent and when to use static or non-static event handler methods.

 

The FML event bus has been merged with the Forge event bus, so FMLCommonHandler#bus returns the same EventBus that's stored in the MinecraftForge.EVENT_BUS field. It's also deprecated, with a comment containing this information.

[Andrew2070]

Added the subscribe event annotation, tried changing to static and non static.

 

Now my game crashes whenever i chat.

[Choonster]

"It crashes" doesn't really tell us anything. Post the latest code and the crash report.

 

Is there a reason you're intercepting and manually re-sending the chat messages? Why not use EntityPlayer#addPrefix or at least ServerChatEvent#setComponent?

 

What version of Minecraft are you using?

Mc Version 1.7.10:

 

Here is the crash report: https://hastebin.com/tewevevide.pas

 

Also i just recently started modding so I don't understand what you mean by: 

EntityPlayer#addPrefix or at least ServerChatEvent#setComponent?

[Ugdhar]

You should update, Minecraft 1.7.10 is no longer supported here.

EntityPlayer#addPrefix is the preferred way to add prefixes to a player's name.

 

If you can't do that, use ServerChatEvent#setComponent to replace the chat message instead of cancelling the event and re-sending the message yourself.

I suspected that may have been the case. As Ugdhar said, 1.7.10 is no longer supported here.
