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.

We have done so in the previous chapter when we retrieved values from config.yml. This will be very similar. However, we must first manually load the configuration using the following code, which will be different. We should only do this if the file actually exists. The file will not exist the first time that the plugin is used, so we do not want an error to occur in that situation.

File file = new File(plugin.getDataFolder(), "warps.yml");
if (file.exists()) {
    YamlConfiguration config = new YamlConfiguration();
    config.load(file);

Now that we have the YAML configuration loaded, we are able to get values from it. Our data has been placed into two unique configuration sections. We will loop through each key of both sections in order to load all of our locations. To get a specific object from a section...
