If you have any trouble figuring out any of the problems mentioned in the challenges or with any other portion of the Bukkit API you can ask help from the Spigot forums (www.spigotmc.org/forums), the official IRC channel for Spigot (www.spigotmc.org/pages/irc), and the Minecraft forums (www.minecraftforum.net).
You can also contact me directly or visit my website at www.codisimus.com. I am always interested in helping out a fellow developer.
You now have the knowledge required to begin programming your own Bukkit plugins. As we did in this chapter, we will have to refer to the documentation to find the required information. Being able to navigate and understand the API documentation will speed up the process of coding. If you are ever unsure of a section of the API, you now know how to find the information that you need. In the next chapter, we'll use the Bukkit API to begin writing code to create your first Bukkit plugin.
