Hey

I am using this code:

    				mc.thePlayer.addChatMessage(new ChatComponentText(EnumChatFormatting.AQUA + finalstring));

And it paint only the first line:

How do I fix this?

Your best bet is to take the string you want to send, and String.split(" "), and add your formatting between each word.

an example from some of my code (the string is already split into params[]):

 

          String msg = "";

	for(int i = 0; i < params.length; i++){
		msg += params[i];
		msg += " ";
		msg += EnumChatFormatting.GRAY.toString() + EnumChatFormatting.ITALIC.toString();
	}

String[] stringList = message.split(" +"); // string broken into words
String formatting = EnumChatFormatting.GRAY.toString() +  EnumChatFormatting.ITALIC.toString(); // formatting codes

resultString = formatting + String.join(" " + formatting, stringList); // result with formatting between words

 

String[] stringList = String.split(" +",message); // string broken into words
String formatting = EnumChatFormatting.GRAY.toString() +  EnumChatFormatting.ITALIC.toString(); // formatting codes

resultString = formatting + String.join(" " + formatting, stringList); // result with formatting between words

"The method join(String, String[]) is undefined for the type String"

	}

It doesnt work

It does split the word but the color doesn't work

I did this:

String[] stringList = msg.split(" ");
    	    		for(int i = 0; i < stringList.length; i++){
    	    			finalstring += stringList[i];
    	    			finalstring += " ";
    	    			finalstring += EnumChatFormatting.AQUA.toString() + EnumChatFormatting.ITALIC.toString();

Well you certainly have to adapt the concepts for your own usage... are you saying you got it fixed or that it still does not work?

For complete clarity, can you please post the entire method containing the lines in question? Then we can make specific edits instead of theoretical ones and get you squared away.

First off put the chat formatting line at the beginning of your loop, before you add the split string. Also I see you made an edit to your post... maybe comment out the snitch replace method thing to see if it is what causes you problems. I personally am having browser issues trying to view your entire class on my mobile device or I could get more in depth

One more thing... add .toString () at the end of the chat formatting.

Thx its working now!

btw I have another question:

I want to make a mod for multiplayer that msg the player every time a player join or leave the server.

How do I identify when a new player join or leave the server?

Well it would be wise to post the question in a new thread, but you will have to hook an EntityPlayer event... is this something you are familiar with? You can most likely find a 5 minute tutorial video on the subject and theforge github references every event you can subscribe to.

Also, I see you are new to the boards; dont be afraid to click that thank you button in the corner if anyone wasof help to you!

I am new with Forge.

I am just trying to make a simple mod for a server I am playing on.

I know only basic java so I am having hard time doing it.

If u know any other mod that does what I want it can really help me

If you are new to forge but interested in learning more, then subscribing to events and maybe writing a custom save file should be within your scope/a good learning experience and easy enough to find basic outlines and tutorials about them. My first thoughts on your approach would be as follows:

 

• create a static String[] to store currently online player names.
  
• subscribe to the EntityJoinWorldEvent https://github.com/MinecraftForge/MinecraftForge/blob/master/src/main/java/net/minecraftforge/event/entity/EntityJoinWorldEvent.java and add that player to the list, and also broadcast any messages to any other players on that list. You'll be using a lot of World.getPlayerEntityByName() and null checks.
  

Don't store the names, but the UUIDs, because there's gonna be name-change support and that will mess up your names.

This is pretty wise, especially if you plan on your server almost never restarting. Unless you are saving this list to file, it will clear out every time you restart the server.

 

Edit: Although if you remove a player from the list every time you find a null, it will be self-cleaning anyway, and the "new name" (when that feature comes available) will be used the next time that individual player logs in. So if all you are using this list for is notifying players of login, you will only run into issues for one specific player, during the specific session in which they changed their name. If you want a list for more sophisticated and long-term uses, then you should most definitely take larsgerrits' advice. If it were me I would start simple and work up, since it's pretty much all stilla challenge for you.

I am not making this mod for the server- this is a bukkit server and I am not the owner

Is it going to work if the mod isnt install on the server?

EnumChatFormatting.RED + String1 + EnumChatFormatting.RESET + String2

That's a big no. It will work in single player. Or if you are the server, any client who also has the mod will be able to log in and it will work. If it is installed on the server a client can not log in unless they have it installed also. Simple as that.

 

EnumChatFormatting.RED + String1 + EnumChatFormatting.RESET + String2

 

? Issue already solved, and that's not it...
