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.

Synchronous versus asynchronous tasks


A task can be run either synchronously or asynchronously. Simply put, when a synchronous task is executed, it must be completed before the server can continue running normally. An asynchronous task can run in the background while the server continues to function. If a task accesses the Bukkit API in any way, then it should be run synchronously. For this reason, you will rarely run a task asynchronously. An advantage that an asynchronous task gives is that it can be completed without causing your server to lag. For example, writing data to a save file can be done asynchronously. Later in this chapter, we will modify the Warper plugin to save its data asynchronously. As for the AlwaysDay plugin, we must run the task synchronously because it accesses the Minecraft server.

Running a task from a BukkitRunnable class

Calling runTask or runTaskAsynchronously on a BukkitRunnable class will cause the task to run immediately. The only time you are likely to use...
