[1.7.2] [Solved] How to display a chat message on enter in a world?

[SackCastellon]

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"));
        
    }

}

[SackCastellon]

Ok, and now?

Player.sendChatMessage(...) ?

 

Assuming that method has been deobfuscated yet.

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?

[BigDaveNz]

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

    }

I like using ChatMessageComponent because you can do things like 'messageComponent.setColor(RED)' - approximate code, and italics and things.

[BigDaveNz]

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)

[Moritz]

But the EntityPlayer class have it. If not MC have removed it. Thats why i calling it.

It mean that MC have removed it, because there isn't any method called .addChatMessage(String) even nor any method with only a String

[BigDaveNz]

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.

Ok, thanks
