The proper way of adding a prefix and suffix to nametags of a player using Scoreboard Teams made with packets and is possibly horribly made by me!

Prefix & Suffix Nametag.md

Feel free to update and expand upon this.

Requirements

• ProtocolLib

Code

package your.package.here;

import com.comphenix.protocol.PacketType;
import com.comphenix.protocol.ProtocolLibrary;
import com.comphenix.protocol.events.PacketContainer;
import com.comphenix.protocol.wrappers.WrappedChatComponent;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import java.lang.reflect.InvocationTargetException;
import java.util.Collection;
import java.util.Collections;
import java.util.UUID;

public class Nametag {

    PacketContainer packet;

    public Nametag(Player player) {
        this.packet = ProtocolLibrary.getProtocolManager().createPacket(PacketType.Play.Server.SCOREBOARD_TEAM);
        String name = UUID.randomUUID().toString().replace("-", "").substring(0, 12);
        this.packet.getIntegers().write(1, 0);
        this.packet.getStrings().write(0, name);
        this.packet.getChatComponents().write(0, WrappedChatComponent.fromText(player.toString()));
        this.packet.getSpecificModifier(Collection.class).write(0, Collections.singletonList(player.getName()));
    }

    public Nametag setPrefix(String prefix) {
        this.packet.getChatComponents().write(1, WrappedChatComponent.fromText(ChatColor.translateAlternateColorCodes('&', prefix) + " "));
        return this;
    }

    public Nametag setSuffix(String suffix) {
        this.packet.getChatComponents().write(2, WrappedChatComponent.fromText(" " + ChatColor.translateAlternateColorCodes('&', suffix)));
        return this;
    }

    public void build() {
        for (Player p : Bukkit.getOnlinePlayers()) {
            try {
                ProtocolLibrary.getProtocolManager().sendServerPacket(p, packet);
            } catch (InvocationTargetException e) {
                throw new RuntimeException("Cannot send packet " + packet, e);
            }
        }
    }
}

Usage

new Nametag(player).setPrefix("&6Test").setSuffix("&aTest").build();

// 1.13+
new Nametag(player).setPrefix("&6Testttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt").setSuffix("&aTestttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt").build();

is there a way to organize the priority of the ranks? i assume I would have to set the name to "0-name" to get that type of effect.

There is, but you'll have to use actual teams for that since this is fake teams and I don't think you can prioritize the fake teams cause well, they're fake.

this is very helpful, thank you for it, I have 1 issue the name is permanently colored black, I add colors to prefix and suffix and it works, but I can't figure out how to change the player name color, can you help with this?

is there a way to organize the priority of the ranks? i assume I would have to set the name to "0-name" to get that type of effect.

You can, just for sake of mind.

Team priorities work under the beggining identifiers:
00
01
02
03
11
15
20

00 shows up first, consider the priorities as if they were indexes in the tablist!

This gist is only lacking how to properly handle the team for the client too, so it removes the team later if player leaves etc

I also have this problem

Not work on 1.19.2.
Will you improve the code to work with the latest versions?
Thanks!
