Building Minecraft Server Modifications

Chapter 2. Learning the Bukkit API

You may be wondering what the difference is between Bukkit and CraftBukkit. Many people use the two words interchangeably. However, they are in fact different files. In chapter one you were introduced to the CraftBukkit jar. In this chapter you will be introduced to the Bukkit API and learn what it allows you to accomplish through programming plugins for a CraftBukkit server. By the end of this chapter you will most likely have numerous ideas for plugins that you will eventually be able to create yourself. This chapter will cover the following in more detail:

  • Understanding the purpose of an API

  • Finding documentation of the Bukkit API

  • Navigating through JavaDocs to find specific information

  • Reading and understanding the documentation

  • Exploring and learning more aspects of the Bukkit API

Introduction to APIs


API is an acronym for Application Programming Interface. An API helps to control how various software components are used. As mentioned in the previous chapter, CraftBukkit includes the Minecraft code in a form that is easier for developers to utilize in creating plugins. CraftBukkit has a lot of code that we do not need to access for creating plugins. It also includes code that we should not use as it could cause the server to become unstable. Bukkit provides us with the classes that we can use to properly modify the game. Basically, Bukkit acts as a bridge between our plugin and the CraftBukkit server. The Bukkit team adds new classes, methods, and so on, to the API as new features develop in Minecraft, but the preexisting code rarely changes. This ensures that our Bukkit plugins will still function correctly months or even years from now. Even though new versions of Minecraft/CraftBukkit are being released. For example, if Minecraft were to change how an entity's...

The Bukkit API documentation


Documentation of the Bukkit API can be found at jd.bukkit.org. You will see several links regarding the status of the build (Recommended, Beta, or Development) and the form of the documentation (JavaDocs or Doxygen). If you are new to reading documentation of Java code, you may prefer Doxygen. It includes useful features, such as a search bar and collapsible lists and diagrams. If you are already familiar with reading documentation then you may be more comfortable using the JavaDocs. In the following screenshot, both API docs are side by side for comparison. The traditional JavaDocs are on the left and the Doxygen documentation is on the right.

The following figure is the inheritance diagram for LivingEntity from the Doxygen site. Take note that on the site you are able to zoom in and click a box to go to that class.

I encourage you to browse through each documentation to decide which one you prefer. In this book we will be using Doxygen but keep in mind that both...

After reading the first 3 chapters I was able to create my first sample plugin for the Minecraft Bukkit (CraftBukkit) server software.Building Minecraft Server Mods is the first book by Cody "Codisimus" Sommers. A great piece of technical writing by a beginner, the first version of the book does suffer from a few editing errors, but I believe that to be a problem caused by the publisher and should not be held against the author.This book is not for beginners, and Cody explains that very early on. I have a bit of experience with Java and I teach computer programming so I had no trouble following the explanations. Cody explains just enough to you to complete the things you need without making it too complicated. I did have a few problems at the start because I tried using Eclipse (which I am not very familiar with) instead of NetBeans which Cody uses throughout the book but I was able to get everything working. He even provides a link to his website where readers can learn basic Java if they don't have experience with the language.The examples are simple enough to understand but complex enough to make them useful and to give you more meat to work on for developing your own plugins or using his examples as a base to start from. The prose of the book is very informal and should be easy to understand for most readers.I was quite happy to start learning how to create plugins for Minecraft servers and the ideas provided in Cody's book have really got me excited about starting some projects. Great work by a new author!

Great book! Ever wanted to learn the ins and outs of a Minecraft server? Find all the information in one place can often be challenging. This book walks you through setting up a Craftbukkit server and essential plugins. Then it takes you further into explaining how you too can build custom plugins to work with Minecraft. I am only currently half way through the book, but am totally delighted. I have read and reviewed other books thinking I just wasted so much time and it didn't even deliver what the title promised. I am very pleased with this book so far. If you are excited and want to learn about Minecraft multiplayer servers I recommend this title.

This a good way to get started learning the Bukkit API. It does have its flaws. The first (though beyond the author's control and probably not a problem when it first came out) is that its becoming outdated.The first plugin you write assumes a method that now returns a collection will return an array. Fortunately its not easy to convert, but you have to know enough Java and be familiar enough with your IDE to to figure it out. Someone who wasn't yet comfortable with these things could be lost.Another is the paradox of saying you should know Java before hand for the book to be useful, and then assuming you don't and teaching a lot of Java basics. I know this probably isn't really completely a flaw, as many may read don't have this knowledge, but for me it did at times feel like too much hand holding on knowledge I thought would be assumed. I would say that if you want to do much with Bukkit of Forge you should know or learn Java -- it will really open up possibilities, and is really the only way you can fully understand anything you aren't spoon-fed.The third is that it spend too much time just talking about servers and how to run them for my taste. Again, like with the Java basics this cuts both ways as many are likely to pick this up because they are into the game and dream of running a server and having custom plugins without actually having run a server before.Slow is something that cuts both ways, depending on how much you know -- for many it may be a good things -- if you know how to run servers and know Java (I've been using Java for years, have run a couple small servers, and written Forge mods, so I probably was ahead of many readers) this may seem to go to slow and the first three chapters may be skipable, but its still does a good job introducing Bukkit). If you are completely new to all this, then this will get you started, as long as your willing to keep learning.Over all its a good book, a good way to get started with the Bukkit API; also, the Kindle version is an excellent deal and lack the flaws found in Kindle editions of some books. Just be warned that in the future Bukkit itself my come to be replaced by a newer API called Spoonge.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
