FastBoard

Lightweight packet-based scoreboard API for Bukkit plugins, with 1.7.10 to 1.20 support.

⚠️ To use FastBoard on a 1.8 server, the server must be on 1.8.8.

Features

No flickering (without using a buffer)
Works with all versions from 1.7.10 to 1.20
Very small (around 600 lines of code with the JavaDoc) and no dependencies
Easy to use
Dynamic scoreboard size: you don't need to add/remove lines, you can directly give a string list (or array) to change all the lines
Everything is at the packet level, so it works with other plugins using scoreboard and/or teams
Can be used asynchronously
Supports up to 30 characters per line on 1.12.2 and below
No character limit on 1.13 and higher
Supports hex colors on 1.16 and higher
Adventure components support

When using Maven, make sure to build directly with Maven and not with your IDE configuration. (on IntelliJ IDEA: in the Maven tab on the right, in Lifecycle, use package).

Gradle

plugins {
    id 'com.github.johnrengelman.shadow' version '8.1.1'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'fr.mrmicky:fastboard:2.0.0'
}

shadowJar {
    // Replace 'com.yourpackage' with the package of your plugin 
    relocate 'fr.mrmicky.fastboard', 'com.yourpackage.fastboard'
}

Manual

Copy FastBoardBase.java, FastBoard.java and FastReflection.java in your plugin.

Usage

Creating a scoreboard

Simply create a new FastBoard and update the title and the lines:

FastBoard board = new FastBoard(player);

// Set the title
board.updateTitle(ChatColor.GOLD + "FastBoard");

// Change the lines
board.updateLines(
        "", // Empty line
        "One line",
        "",
        "Second line"
);

Example

Small example plugin with a scoreboard that refreshes every second:

package fr.mrmicky.fastboard.example;

import fr.mrmicky.fastboard.FastBoard;
import org.bukkit.ChatColor;
import org.bukkit.Statistic;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;
import org.bukkit.plugin.java.JavaPlugin;

import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

public final class ExamplePlugin extends JavaPlugin implements Listener {

    private final Map<UUID, FastBoard> boards = new HashMap<>();

    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);

        getServer().getScheduler().runTaskTimer(this, () -> {
            for (FastBoard board : this.boards.values()) {
                updateBoard(board);
            }
        }, 0, 20);
    }

    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player player = e.getPlayer();

        FastBoard board = new FastBoard(player);

        board.updateTitle(ChatColor.RED + "FastBoard");

        this.boards.put(player.getUniqueId(), board);
    }

    @EventHandler
    public void onQuit(PlayerQuitEvent e) {
        Player player = e.getPlayer();

        FastBoard board = this.boards.remove(player.getUniqueId());

        if (board != null) {
            board.delete();
        }
    }

    private void updateBoard(FastBoard board) {
        board.updateLines(
                "",
                "Players: " + getServer().getOnlinePlayers().size(),
                "",
                "Kills: " + board.getPlayer().getStatistic(Statistic.PLAYER_KILLS),
                ""
        );
    }
}

Adventure support

For servers on modern PaperMC versions, FastBoard supports using Adventure components instead of strings, by using the class fr.mrmicky.fastboard.adventure.FastBoard.

RGB colors

When using the non-Adventure version of FastBoard, RGB colors can be added on 1.16 and higher with ChatColor.of("#RRGGBB") (net.md_5.bungee.api.ChatColor import).

ViaBackwards compatibility

When using ViaBackwards on a post-1.13 server with pre-1.13 clients, older clients might get incomplete lines. To solve this issue, you can override the method hasLinesMaxLength() and return true for older clients. For example using the ViaVersion API:

FastBoard board = new FastBoard(player) { 
    @Override
    public boolean hasLinesMaxLength() {
        return Via.getAPI().getPlayerVersion(getPlayer()) < ProtocolVersion.v1_13.getVersion(); // or just 'return true;'
    }
});
