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. Additional API features will become a breeze to learn after tackling these more complicated tasks.

Configurable data types


You could easily make most variables in your plugin configurable. The following is a table of various data types and examples of why you may want them to be configurable:

Data type

How it may be used

int

Setting the health of a mob when it spawns

boolean

Turning a specific feature on or off

String

Changing a message that is sent to a player

ItemStack

Making a customized item appear

Tip

Adding an ItemStack value to a configuration file is complicated, but will be explained towards the end of this chapter.

We are going to make MobEnhancer configurable. We want to be able to set the value of the zombies' health. That would simply be one integer value. Let's expand the plugin to support additional creature types. We will create our config file first and then adapt our program to be able to modify different types of mobs. Therefore, we have decided that our config file will include a single integer for each type of mob. This integer will be the mob's health.
