Overview of this book

If you have ever played Minecraft on a public server then the chances are that the server was powered by Bukkit. Bukkit plugins allow a server to be modified in more ways than you can imagine. Learning to program your own server mods will allow you to customize the game to your own liking. Building Minecraft Server Modifications is a complete guide that walks you through the creation of Minecraft server mods. From setting up a server, to testing your newly made plugins, this book teaches you everything you need to know. With the help of this book you can start practising for a career in software development or simply create something awesome to play with your friends. This book walks you through installing your own Minecraft server for you and your friends. Once your server is running, it will aid you in modifying the game by programming Bukkit plugins. You will learn how to program simple plugin features such as player commands and permissions. You will also learn more complex features including listening for events, creating a configurable plugin, and utilizing the Bukkit scheduler. All of this will be accomplished while writing your own server mods. You will become familiar with the most important aspects of the Bukkit API.

That way if it is night when the plugin is enabled, the time will be set to noon right away. As for the period, we could repeat the task every second if we wanted to keep the sun always directly above. The task only contains one simple line of code so repeating it that often will not cause much lag to the server. However, repeating the task every minute will still prevent the world from ever growing dark. Therefore we will delay the task by 0 ticks and repeat it every 1200 ticks. The entire AlwaysDay plugin is given in the following code:

package com.codisimus.alwaysday;

import org.bukkit.Bukkit;
import org.bukkit.World;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scheduler.BukkitRunnable;

public class AlwaysDay extends JavaPlugin {
  @Override
  public void onEnable() {
