Recommended Posts

As, the title says, i want to know how to display a chat message on enter in a world.

 

Thanks for helping.

 

SOLUTION:

 

Main.class

 

package SackCastellon.core;

import cpw.mods.fml.common.FMLCommonHandler;
import SackCastellon.core.event.SkcEvent;
import SackCastellon.core.proxy.CommonProxy;
import SackCastellon.core.reference.Reference;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.Mod.Instance;
import cpw.mods.fml.common.SidedProxy;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;

@Mod(modid=Reference.ID, name=Reference.NAME, version=Reference.VERSION, dependencies=Reference.DEPENDENCIES)
public class SKCCore {

@Instance(Reference.ID)
public static SKCCore instance;

@SidedProxy(clientSide=Reference.CLPROXY, serverSide=Reference.CMPROXY)
public static CommonProxy proxy;

@EventHandler
public void preInit(FMLPreInitializationEvent event)  {

        	FMLCommonHandler.instance().bus().register(new SkcEvent());
        
        	System.out.println("Event Handler Initialized");

}

@EventHandler
public void load(FMLInitializationEvent event)  {}

@EventHandler
public void postInit(FMLPostInitializationEvent event)  {}

}

 

 

Event.class

 

package SackCastellon.core.event;

import net.minecraft.util.ChatComponentText;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent.PlayerLoggedInEvent;

public class SkcEvent {

    @SubscribeEvent
    public void onPlayerLogin(PlayerEvent.PlayerLoggedInEvent event) {

    	event.player.func_146105_b(new ChatComponentText(event.player.getDisplayName() + " is testing chat messages"));
        
    }

}

Player.sendChatMessage(...) ?

 

Assuming that method has been deobfuscated yet.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I'm just updating now. I haven't got a working version yet, simply because of the amount of changes I have to make before I can even run MC. 1.7.2 broke a lot haha. But anyway, You need to Hook into PlayerLoggedInEvent which is in PlayerEvent. Also with chat messages now this is the code for basic, non styled/non translated text.

Chatting to a player, command sender and Broadcasting a message to all players is here. (be aware this is untested but "should" work).

 

The EIChatComponent is merely "[EI] " which gets added to all of my chat messages, and is usually styled although I haven't figured out colours/bold etc. for 1.7.2 yet.

I'm not verry good on Java, so how can i hook it?

First you need to create a class to put all your @SubscribeEvent (1.7) annotations in.

 

Then you subscribe to the appropriate event.

 

Then you initialise your event handler

 

https://github.com/BigDaveNz/EnchantInsanity/blob/master/common/nz/co/bigdavenz/ei/core/handler/EIEventHandler.java

 

That's my event handler. the Key line  that you need to know is line 13

 

My class that processes the events is here:

 

https://github.com/BigDaveNz/EnchantInsanity/blob/master/common/nz/co/bigdavenz/ei/event/EIEvent.java (note this is 1.6.4)

 

As you can see that is the class that is referenced in line 13 of EIEventHandler.java

 

for 1.7 FML now has annotated events.

 

@SubscribeEvent

    public static void onPlayerLogin(PlayerEvent.PlayerLoggedInEvent event) {

        //Do stuff

    }

ChatMessageComponent is 1.6.4, It no longer Exists, theres now 3 components. Translation, Style, and Text. They all are used together to output a result. Since most functions are Obfuscated, styling is the hard bit at the moment.

Sorry, I've been busy.

 

I made this code, based on your, but doesn't work:

 

SkcEventHandler.java

 

SkcEvent.java

 

PlayerLoginEvent.java

 

ChatMessageHandler.java

 

And the EventHandler initialized on the Main class:

 

SKCCore.java

Why so complicated?

 

Just make it like this in your event:

 

        @SubscribeEvent
    public void onPlayerLogin(PlayerEvent.PlayerLoggedInEvent event) {
            
        event.player.addChatMessage("Welcome");
        
        LogHelper.info(Reference.ID, event.player.getDisplayName() + " logged In!");
        
    }


 

and by the way the static could be the problem.

There isn't a .addChatMessage(String); or some similar method in forge 996 (as i've looked for)

All chat strings have been moved to IChatComponents. there is still an addChatMessage()... Although it requires a component as the input, rather then a string.

 

I'm currently on holiday at the moment, but I will be back on friday evening. So if you still haven't figured it out by then, I'll test in a 1.7 environment. And see if I can fix it for you.
