Building Minecraft Server Modifications - Second Edition

Chapter 2. Learning the Bukkit API

In this chapter, you will be introduced to the Bukkit API and learn what it allows you to accomplish through programming plugins for a Spigot server. By the end of the 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 topics in detail:

  • Understanding the purpose of an API
  • Finding the documentation of the Bukkit API
  • Navigating through Javadocs to find specific information
  • Reading and understanding the documentation
  • Exploring and learning the features of the Bukkit API

Introduction to APIs

API stands for Application Programming Interface. An API helps control how various software components are used. As mentioned in the previous chapter, Spigot includes the Minecraft code in a form that is easy for developers to utilize when creating plugins. Spigot has a lot of code that we need not access in order to create plugins. It also includes code that we should not tamper with, as it may cause the server to become unstable. Bukkit provides us with the interfaces that we can use to properly modify the game while restricting access to other portions of the code. An interface is essentially a shell of a class. It includes methods, but the methods are empty. The Spigot server contains classes for each interface. The classes implement the interfaces and fill each method with the appropriate code.

To explain this better, let's imagine the Bukkit API as a menu to a pizza shop. The menu contains different types of pizza, such as pepperoni, Hawaiian, and meat lovers...

The Bukkit API documentation

Documentation of the Bukkit API can be found at hub.spigotmc.org/javadocs/bukkit/. The Bukkit.jar file that you built in Chapter 1, Deploying a Spigot Server also contains the Spigot API, which can be found at hub.spigotmc.org/javadocs/spigot/. The Spigot API is a superset of the Bukkit API, which means that it contains all the classes, interfaces, and so on that are present in the Bukkit API, as well as some additional classes that are unique to the Spigot project. If you want your plugin to support Spigot and CraftBukkit servers, then you will want to develop by using the Bukkit API. If you choose to only support Spigot servers, then you can develop using the Spigot API. In this book, we will refer to the Bukkit API. However, using the Spigot API will yield the same results.

Navigating through the Bukkit API documentation

We can go through the Bukkit API documentation to get a general idea of what we can modify on a Spigot server. Server-side plugins are different from client-side mods in that we are limited with what we are able to modify in the game using server-side plugins. For example, we cannot create a new type of block, but we can make lava blocks rain from the sky. We cannot make zombies look and sound like dinosaurs, but we can put a zombie on a leash, change its name to Fido, and have it not burn in the daylight. For the most part, you cannot change the visual aspect of the game, but you can change how it functions. This ensures that everyone who connects to the server with a standard Minecraft client will have the same experience.

For some more examples on what we can do, let's have a look at the various pages of the API's documentation:

Navigating through the Bukkit API documentation

You will see that the classes and interfaces within the API are selectable in the lower left section...

Understanding the Java documentation

Let's look at a method that is included in the World class to see what information it provides us. Click on the link to view the createExplosion(Location loc, float power, boolean setFire) method. You will be brought to a method description that is similar to the one shown in the following screenshot:

Understanding the Java documentation

The screenshot explains each parameter and the return value for the method. This method requires that we pass three parameters to it, which is explained as follows:

  • Where the explosion should take place
  • How powerful the explosion should be
  • Whether the explosion should cause the surrounding blocks to ignite in flames

If the returned value is void, then the method will not send any information back to us. In this example, the method returns a boolean value. On reading the documentation, you will learn that the returned value is whether or not the explosion actually occurred. If another plugin prevented the explosion from happening, then the createExplosion...

Exploring the Bukkit API

Now that you are familiar with the Bukkit API documentation, I advise you to look through it on your own. You will find interesting methods; many of these methods will spark ideas for cool plugins that you may want to make. Note that there may be additional links to view more methods for an object. For example, a Player is a type of LivingEntity. Therefore, you can call a LivingEntity method on a Player object. This inheritance is shown after the method summary, as shown in the following screenshot:

Exploring the Bukkit API

If you are ever going to try and think up an idea for a plugin, browsing through the API documentation will surely give you some ideas. I suggest reading the class pages, listed as follows, as they will be the classes that you will frequently use in your future plugins:
