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.

Adding a delayed task to a plugin


We will now add a warp delay to our Warper plugin. This will require players to stand still after running the warp or home commands. If they move too much then the warp task will be canceled and they will not be teleported. This will prevent players from teleporting when someone is attacking them or they are falling to their death.

If you haven't already, add a variable of warpDelay within your main class. This is given in the following line of code:

static int warpDelay = 5;

This time will be in seconds. We will multiply it by 20 to calculate the number of ticks that we wish to delay the task.

We will also need to keep track of who is in the process of warping so that we can check if they move. Add another variable of current warpers. This will be a HashMap so that we can keep track of which players are warping and the tasks that will be run to teleport them. That way, if a specific player moves, we can get their task and cancel it. This is shown in the following...
