Problem PEX Prefixes and ASyncPlayerChatEvent

Hello,
This is my first time posting on this forum (I think), so bear with me.

This is simply a random plugin with a bunch of features randomly in it (mostly for my own practice)

I've been trying to make it so that prefixes appear when chatting
So it should look something like this

%Prefix%DisplayName%Suffix: %Message

Here's my code.

This is my Event Handler

Code:java

 
public class ChatEvent implements Listener{
public ChatEvent(TestPlugin plugin) {
plugin.getServer().getPluginManager().registerEvents(this, plugin);
}
 
@EventHandler (priority = EventPriority.HIGHEST)
public void onMessage(AsyncPlayerChatEvent e){
 
if (e.isCancelled()) {
return;
}
 
Player player = e.getPlayer();
 
String WorldName = player.getWorld().getName();
PermissionUser user = PermissionsEx.getPermissionManager().getUser(player);
 
if (user == null)
return;
 
String message = e.getMessage();
String format = "%prefix%name%suffix: %message";
format.replace("%prefix",user.getPrefix(WorldName));
format.replace("%suffix",user.getSuffix(WorldName));
format.replace("%name", "%1$s");
format.replace("%message", "%2$s");
 
e.setFormat(format);
e.setMessage(message);
 
 
}
}

Then i put this in my main class

Code:java

new ChatEvent(this);

I've tried a lot of different ways to accomplish this and I'm still not able to do it
I tried to grab the group of the user then grab the player. (I tried with Vault, didn't work, but i didnt' really know what i was doing)

I've been also trying to integrate Prefixes/Suffixes into my MOTD EventHandle class.
I wanted the prefix and the suffix to appear with the DisplayName
So something like this

Welcome to the Server [insert PrefixDisplayNameSuffix]!

I wasn't able to do that either.

 

firefwing24 Strings are immutable, meaning that it will give you a new String when call replace(). You have to assign that to something, currently you are just calling it and doing nothing with the String it returns.

So should it be...

Code:

format = format.replace(stuffhere,stuffhere);

But how is it still displaying <name> message completely fine?
Because if replace doesn't actually do anything to the string by itself, shouldn't the message be changed into

%prefix%name%suffix : %message (literally this, not their counterparts)?

 

firefwing24 Do you understand what it means for a method to "return" something? If not, you may want to touch up on Java. If you do, then keep in mind that Strings are immutable and will return a new String everytime a change is made to one (assuming the method changing returns a String), meaning you have to assign it to a variable so that you have the newly created String.

Sorry if i ever sound noobish to coding. I'm majoring in CS but it's still somewhat new to me (esp. java) I just thought Bukkit plugins would be a fun way to become more familiar with java (this isn't my first thing with java though lol).
I know what it means to return. Wouldn't my answer still work? It is somewhat a recursive.
Anyways, i made another method to return replaceFormat and

Code:java

 
        public String replaceFormat(Player player, String format) {
        PermissionUser user = PermissionsEx.getPermissionManager().getUser(player);
        String WorldName = player.getWorld().getName();
        return format.replace("%prefix",user.getPrefix(WorldName)).replace("%suffix",user.getSuffix(WorldName)).replace("%name", "%1$s").replace("%message", "%2$s");
    }

then I would place
String newFormat = this.replaceFormat(player, format); in that eventHandler above.
and change e.setFormat(format); to e.setFormat(newFormat);

Is this correct? or am i still doing it wrong.

 

firefwing24 That is a way of doing it

 

So just like before I made these changes, it still leaves it as the default chat.
<firefwing24> hi
instead of
[insertprefixhere]firefwing24: hi

There's still something wrong with my code.

 

firefwing24 Post the code (full class would be preferred)

 

Code:java

package io.github.firefwing24.TestPlugin;
 
 
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;
 
import ru.tehkode.permissions.PermissionUser;
import ru.tehkode.permissions.bukkit.PermissionsEx;
 
public class ChatEvent implements Listener{
    public ChatEvent(TestPlugin plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
    }
 
    @EventHandler (priority = EventPriority.HIGHEST)
    public void onMessage(AsyncPlayerChatEvent e){
 
        if (e.isCancelled()) {
            return;
        }
 
        Player player = e.getPlayer();
 
        PermissionUser user = PermissionsEx.getPermissionManager().getUser(player);
 
        if (user == null)
            return;
 
        String message = e.getMessage();
        String format = "%prefix%name%suffix: %message";
 
        this.replaceFormat(player, format);
 
        e.setFormat(format);
        e.setMessage(message);
 
 
    }
 
    public String replaceFormat(Player player, String format) {
        PermissionUser user = PermissionsEx.getPermissionManager().getUser(player);
        String WorldName = player.getWorld().getName();
        return format.replace("%prefix",user.getPrefix(WorldName)).replace("%suffix",user.getSuffix(WorldName)).replace("%name", "%1$s").replace("%message", "%2$s");
    }
}

Actually after removing all the plugins except for my plugin and PermissionsEx i ended up with this error.
Sorry for double post.

EDIT: I realized i didn't save my code completely. I'll try again
EDIT2: I still get same Error, Except this time it says Netty IO #1

I did end up finding the answer to this problem.
It was a lot more complicated than i expected.
Only problem is that i followed some code from another plugin, so I don't think it's fair to that developer to post the straight up code.

Some Hints:
I forgot to add
String newFormat = this.replaceFormat(player, format);

Make sure you translate color codes. (you'll need another method to do this)

For prefix/suffix for PermissionsEx, I used the follow commands. Please note that "getGroups()[0]" is a deprecated command.

Code:java

 
        String prefix = PermissionsEx.getUser(player).getGroups()[0].getPrefix();
        String suffix = PermissionsEx.getUser(player).getGroups()[0].getSuffix();
