Special characters in chat...

The original thread by Father Of Time who seems to have disappeared from the face of the earth, got me wondering how to do this with other characters...

I skimmed the thread, but it seemed like too much work for what I was trying to achieve.

Code:

 public void ModifyAllowedCharacters() throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException
 {
  Field field = SharedConstants.class.getDeclaredField("allowedCharacters");
  field.setAccessible(true);
  Field modifiersField = Field.class.getDeclaredField( "modifiers" );
  modifiersField.setAccessible( true );
  modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);
  String oldallowedchars = (String)field.get(null);
  String suits = "\u2665\u2666\u2663\u2660";
  StringBuilder sb = new StringBuilder();
  sb.append( oldallowedchars );
  sb.append( suits );
  field.set( null, sb.toString() );
 }

This is what it came down to, but I'm just curious why so much work for something that could probably be more simple?

 

Do you just need to call that once to allow more characters?

 

ZeusAllMighty11 Maybe you should understand what it does to understand why so much work is needed.
The class "net.minecraft.server.SharedConstants" is not a bukkit class. As long as bukkit builds on the mc server there is no other way to access the field "allowedCharacters" which holds the characters.

gomeow yes, everytime you add new ones.

 

that screen is mine dude if you want the implementation just pm me.

Well ill post her how i implement this (The code That @Father Of Time do)

Atention, i do this in 1.2.5 and just to test @Father Of Time code.

In your main class

Code:

    //The code below is made by "Father Of Time" on bukkit forum.
    //Thanks you.
    public void ModifyAllowedCharacters() throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException
    {
    Field field = SharedConstants.class.getDeclaredField("allowedCharacters");
    field.setAccessible(true);
    Field modifiersField = Field.class.getDeclaredField( "modifiers" );
    modifiersField.setAccessible( true );
    modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);
    String oldallowedchars = (String)field.get(null);
    String suits = "\u2665\u2666\u2663\u2660\u263A\u263B\u266A\u266B\u2642\u2640\u2625\u2680\u2681\u2682\u2683\u2684\u2685";
    StringBuilder sb = new StringBuilder();
    sb.append( oldallowedchars );
    sb.append( suits );
    field.set( null, sb.toString() );
    }

Then i test it in a PlayerChatEvent

Code:

@EventHandler
    public void Chat(PlayerChatEvent event){
        String mensaje = event.getMessage();
        Player player = event.getPlayer();
       
        char cara1 = 0x263A;
        char cara2 = 0x263B;
        char nota1 = 0x266A;
        char nota2 = 0x266B;
        char corazon = 0x2665;
        char rombo = 0x2666;
        char trebol = 0x2663;
        char picas = 0x2660;
        char hombre = 0x2642;
        char mujer = 0x2640;
        char ankh = 0x2625;
         
        char die1 = 0x2680;
        char die2 = 0x2681;
        char die3 = 0x2682;
        char die4 = 0x2683;
        char die5 = 0x2684;
        char die6 = 0x2685;
         
        if(player.isOp()){
            mensaje = mensaje.replace(":c1:", Character.toString(cara1));
            mensaje = mensaje.replace(":c2:", Character.toString(cara2));
            mensaje = mensaje.replace(":n1:", Character.toString(nota1));
            mensaje = mensaje.replace(":n2:", Character.toString(nota2));
            mensaje = mensaje.replace(":c:", Character.toString(corazon));
            mensaje = mensaje.replace(":r:", Character.toString(rombo));
            mensaje = mensaje.replace(":t:", Character.toString(trebol));
            mensaje = mensaje.replace(":p:", Character.toString(picas));
            mensaje = mensaje.replace(":h:", Character.toString(hombre));
            mensaje = mensaje.replace(":m:", Character.toString(mujer));
            mensaje = mensaje.replace(":ankh:", Character.toString(ankh));
           
            mensaje = mensaje.replace(":die1:", Character.toString(die1));
            mensaje = mensaje.replace(":die2:", Character.toString(die2));
            mensaje = mensaje.replace(":die3:", Character.toString(die3));
            mensaje = mensaje.replace(":die4:", Character.toString(die4));
            mensaje = mensaje.replace(":die5:", Character.toString(die5));
            mensaje = mensaje.replace(":die6:", Character.toString(die6));
           
            event.setMessage(mensaje);
        }
    }

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I edited the code, so you dont have to change the imports for the plugin.
That means that plugins dont have to be updated for every bukkit version.

Code:java

 
//The code below is made by "Father Of Time" on bukkit forum (edited by "CoderCloud").
//Thanks you.
public void modifyAllowedCharacters() throws Exception{
    String pack = Bukkit.getServer().getClass().getName();
    pack = (pack = pack.substring(0, pack.lastIndexOf("."))).substring(pack.lastIndexOf(".") + 1, pack.length());
    Class<?> c = getClass().getClassLoader().loadClass("net.minecraft.server." + pack + ".SharedConstants");
    Field f = c.getDeclaredField("allowedCharacters");
    f.setAccessible(true);
    Field mod = Field.class.getDeclaredField("modifiers");
    mod.setAccessible(true);
    mod.setInt(f, f.getModifiers() & ~Modifier.FINAL);
    String s = (String) f.get(null);
    s = s + "\u2665\u2666\u2663\u2660\u263A\u263B\u266A\u266B\u2642\u2640\u2625\u2680\u2681\u2682\u2683\u2684\u2685";
    f.set(null, s);
}
 

 

you could use, ChatColor.translateAlternateColors to do this, you can just paste the non ascii characters in eclipse only bad side is when you refactor your project eclipse change them into ? symbols

edit I show my listeners
https://github.com/xize/fEssentials...ze/essentials/events/chat/chat_highlight.java

and https://github.com/xize/fEssentials...src/xize/essentials/events/chat/smilleys.java

its isn't the best practice though but maybe this is what you mean?

 

You guys are really making this hard for yourselves. Read up on UTF-8 characters and implement them into the code replacing the chat with those symbols. You do not require any code in order to use these symbols!
