Overview of this book

Minecraft is a sandbox game that allows you to play it in any way you want. Coupled with a multiplayer server powered by Spigot, you can customize the game even more! Using the Bukkit API, anyone interested in learning how to program can control their Minecraft world by developing server plugins. This book is a great introduction to software development through the wonderful world of Minecraft. We start by instructing you through how to set up your home PC for Minecraft server development. This includes an IDE complete with the required libraries as well as a Spigot server to test on. You will be guided through writing code for several different plugins. Each chapter teaches you new skills to create plugins of increasing complexity, and each plugin adds a new concept of the Bukkit API By the end of the book, you will have all the knowledge you need about the API to successfully create any type of plugin. You can then practice and build your Java skills through developing more mods for their server.

Communicating among events


The plugin works exactly as intended, but what if we have a change of heart and begin to miss the sound of rain? Alternatively, what if our town bursts into flames and it must be extinguished quickly? We do not want to limit our power as an administrator by denying ourselves the use of the /toggledownfall command. Next, we will listen for this command to be issued, and when it is issued, we will allow the weather to change. Ultimately, we will still be able to control the weather manually, but the weather will not start on its own.

Let's create another EventHandler method. This time, we will listen for a console command being sent so that we can set a Boolean flag, as follows:

@EventHandler (ignoreCancelled = true, priority = EventPriority.MONITOR)
public void onPlayerCommand(PlayerCommandPreprocessEvent event) {
  //Check if the Player is attempting to change the weather
  if (event.getMessage().startsWith("/toggledownfall")) {
    //Verify that the Player has permission...
