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();

1.13+

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?

I also have this problem

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