How to create a plugin Minecraft

You often play Minecraft The now iconic video game sandbox designed by Markus "Notch" Persson, and has also created his own server, which he now would like to expand with new features. In particular, you have heard that it is possible to program some Plugin But you don't know where to start No problem: you have come to the right place!

In fact, in this guide I will explain in detail how to create a plugin for Minecraft giving you a concrete example of what can be achieved and explaining how players often use them. I assure you that it is a less complex procedure than you might imagine.

What do you say? Are you ready to customize your minecraft server? I think you can't wait to see your code in action. Come on then, all you have to do is follow the quick instructions below. That said, I have nothing left but to wish you a good read and have fun.

Create a server and download the program necessary
How to create a Minecraft plugin

Before going into the details of the procedure in how to create a plugin for Minecraft I think you will be interested in learning more about this possibility.

Well, plugins are used in Mojang's title to expand the possibilities it offers spigot, Modified APIs (i.e. software libraries) that allow create Minecraft servers with personalized functions, much richer in possibilities and flexible than the official ones. Everything is done through the Programming language Java Therefore, as you have already guessed, the changes you are about to make will only be feasible in the The PC version of Minecraft Java.

Obviously, the changes you can make on the server depend on your imagination and your programming knowledge. If you want concrete examples of what developers around the world have created, I suggest you take a look at the page dedicated to Spigot plugins.

As you can see from the page I mentioned above, there really is everything. There are those who created custom wings and those who introduced volcanic eruptions in the Mojang title. I mean.., learn to program the plugins for Minecraft servers it can be particularly interesting.

However, before starting with the instructions, it is good to underline two aspects: in this tutorial I will make a practical example related to a Spigot server But there are several types of virtual rooms in Minecraft, as you can read on this page (in English). I will, however, dwell on the type of server in question, as the most widely used, but if you are a fanatic you may want to take a look at the other solutions available.

For the rest, as mentioned above, to create a plugin for a Spigot server you need Java programming. In this guide I'll just explain how to make your first working plugin in no time, using the rudiments of this programming language.

It would be impossible to explain how to program in Java in an advanced way in a single tutorial. It takes months, if not years, of study to actually learn a programming language. Therefore, if you want to delve into the subject, I suggest you consult my tutorials on how to start programming, how to program in Java and how learn java, in which I have recommended many suitable resources for this purpose.

Create a server and download the necessary programs

Having made all the necessary premises, it is time to take action by establishing a Spigot Server for Minecraft on local host (that is, on your computer) and downloading the appropriate programs to make a plugin. To give you some concrete examples, I'll examine creating a Spigot server at Windows.

Well the first thing you have to do is install Go e OpenJDK 8 two programming software needed to create such a virtual room. To do this, connect to the official Git website and press the button Download. Then open the file Git- [versione].exe obtained and press the buttons in succession Next (12 occurrences), Install e Next to complete the installation.

So, linked to the OpenJDK web page, check the box OpenJDK 8 and press the The latest release. In this way, the file will be downloaded to your PC. OpenJDK- [versione]… msi…. Open the latter, and then click the button Next check the box related to license conditions and press the buttons successively Next, Next, Install, Yes e Finalize.

Little note: Spigot developers would recommend using Java SE 8 runtime environment… Downloadable through the official portal, instead of OpenJDK8. However, in that case, to start the download you need to register a Oracle account and the procedure also requires information such as company name you work for and the office phone number so I preferred to suggest an easier way.

That being said, once the aforementioned programs are installed, you have to compile the file from the server via BuildTools.java - Files that you can download simply by clicking here. When the download is complete, open Go Bash which is part of the program you installed earlier, and moves the file BuildTools.java en desk. Go back up. Go Bash... type the command ... cd desktop and prizes Send at keyboard.

At this point, type the command java -jar BuildTools.java and prizes Send. Perfect, you will see in the terminal the progress status of the create the jar file from your Spigot server. You may have to wait a few minutes, as there are also multiple downloads for everything to work.

In any case, after the procedure is finished, if everything has been done correctly, you should see that some files have appeared on your desktop and that in the Go Bash there is the inscription Success.

At this point you can close the Git Bash window and start the file spigot- [versione] .jar on the desk. If everything has been done correctly, you should see the window The Minecraft server. If it doesn't, try opening the eula.txt that you find on the desktop and change the value false en true.

Great, now your server is ready. To verify that it is working, just start Minecraft in the latest version available, press the button Multiplayer then in the Direct access…scribe… localhost and press the Enter the server.

If everything has been done correctly, you will see that your character will enter the server and that in the window The Minecraft server will appear in Nickname that you have chosen for the title of Mojang. Congratulations, you now have a working Spigot server !

For more information about the changes that can be made by default in the virtual room and for more details about the installation phase, also with respect to other versions and platforms, I invite you to consult the Spigot website (in English).

Now that you have seen that the room virtual works, you can log out and close both the game and the Minecraft server window.

However, you still need one last program before you can start creating your plugin: a integrated development environment (IDE). In short, it is a program that allows write and compile Java code.

There are many such programs, as you can read in my guide on the subject. Anyway, I recommend IDEA IntelliJ which is relatively easy to use. To download it, simply go to its official website and press the button twice DOWNLOAD.

Once the download is complete, open the file idealC- [versione] .exe obtained and successive awards in Next, Next, Next e Install then check the box Run the IDEA IntelliJ and click Finalize to finish the assembly.

How to create a Minecraft plugin

After creating a Spigot server and installing all the appropriate programs, the "climax" arrived, that is, the creation of the plugin.

If you have followed the instructions I gave you in the previous chapter, you already have the IDE window available Intellij IDEA on your screen. Then press the button Skip the rest and set the default values and click on the New project. After that select the Java in the upper left corner and press the button twice Next.

At this point, give a project's name (for example, Plugin-) and click the button Finalize. You can press on Close in case some "tutorial" windows appear on the screen.

After that, press the voice Archive in the upper left corner and click Project structure. Move, then, in the Libraries... click on the icon ... +… Click on the entry… Java… Select the… server jar files and awards in OK.

Great, now you've successfully imported all the libraries out of the box. After that, close the library window, expand projects folder present left, do right-click in the folder src and select the items New menu that is proposed to you, and then assigning the name that you prefer (for example,).

After that you do right-click en package you just created, which is on the left, and select the elements Java class from the menu that is offered to you. So, hit the name you want (for example, Plugin) and press OK.

Alright, now is the time to write the code. The first thing to do is import JavaPlugin To do this, enter the line at the top of the file import org.bukkit.plugin.java.JavaPluginclosing with semicolon.

After that, press Send to create some space line and start creating your own class writing, for example, public class Plugin extends JavaPlugin. In simple terms, you are creating a class that extend that the JavaPlugin used by developers to create plugins for Minecraft.

Of course you have to end everything with support. In case JavaPlugin is not recognized, try reimporting the vase file from the server in the way I showed you before.

Then press with the Right mouse button in the folder src and select the items New; Archive from the menu that opens, giving it the name plugin.yml. Here you have to enter all Background information related to the plugin, from its name to the class principal through version guidance on description and the commands. In this case, everything is very simple: you just have to use the variables name, principal, version, description e commands followed by : and enter its "value".

In particular, in name you have to write the plugin name (do not insert spaces for any reason), in principal the name of class that you created previously (anticipated by the package name and without extension), in version insert the version that you consider more correct (for example, 0.0.1 if it is a preliminary stage, 1.0.0 if you consider it "finished") and in description you have to enter it description of the plugin (eg Plugin made through the tutorial).

Finally, in commands it is necessary to insert, after the colon, the order name you want to use (for example, sitoweb), followed by the : and having within it the parameters description (description) and use (method by which the user can use the command, for example, / sitoweb).

Perfect, now you have the "space" in which to make your changes. I will give you a very simple example from which you can start making more advanced plugins. More precisely, I will explain how to create a plugin that allows the user to obtain the URL from the creator's official website from the server simply using the / sitoweb command inside the Minecraft server.

To bring this plugin to life, go back inside the Java file that you created before and add in your head two other imports namely import org.bukkit.command.Command e import org.bukkit.command.CommandSender. The latter are used to use the tools to "receive" user commands.

After that, you need to override the onEnable () e onDisable () inside the plugin class. To do this, you only need to use a @Override before method creation the public void .... I suggest you use the indentation with the plug to make the code more "readable". I remind you that you can write some comments to the code through //What's written on those lines will be ignored during compilation: it's just so you remember what that code is for.

In this specific plugin we will not use these methods, but the structure is usually this, so it was correct to explain it to you. The method we will use instead for this example is the one that onCommand designed to "respond" to user commands. Here we give how entry or the variables in parentheses, CommandSender that is, the user who sends the command, and Command that is, the command itself. You must also add a Rope and a Rope[] in order to correctly perform the Cancel.

Inside the onCommand method there must be what happens when the user sends a certain type of command. In this case, I decided that the command the user should use to get the website URL is simply / sitoweb. For this reason, you should check the input submitted by the user. I have already explained that it is contained in the type Command which I "instantiated" through the variable called command.

To perform the check, a si which is a "yes." The code in this case is the following: if (comando.getName().equalsIgnoreCase("sitoweb")) { utente.sendMessage("Il mio sito è [www. Parada Creativa](http://www. Parada Creativa/)"); }. In short, I'll take the command by the method getName () I look, regardless of case insensitivity, if the command is really "sitoweb" through the method equalsIgnoreCase and if so, I will send a message with the url of my site to the user through the sendMessage.

At this point, you have successfully finished programming the plugin that returns the url from the website to the user when the user uses the command / sitoweb. Now comes the part of compiling… Which will create the .jar file for your plugin.

To proceed, click on Archive in the upper left corner click Project structure... go to the card ... Artifacts…Press the button… + and select the items Of modules with dependencies. Press, then on OK... delete, through the icon ... - the inscription Extracted spike file [versione] .jar and press the button first Apply and then on that OK.

At this point, click on the Build at the top and press the option Build artifacts. After that, click on the Build Wait a few seconds and the system will inform you of the fact that compiling. You will see the red folder in the upper left corner ... fuera.

Expand, therefore, its content, also expand the folder artifacts and you will see the .jar of your plugin. Now, press with the Right mouse button and select the Show in Explorer.

In this way, you will see on the screen the way to File Browser with the .jar files from your plug. Now, you have to move the file in question that you have generated inside the folder plugins from your server. If you've followed my instructions, you should find the latter in the desk.

Later, start the jar file server and wait for the window to appear on the screen The Minecraft server and that branch. When you finish with the last one, write parade on the server console and press Send. Thereafter, restart the jar file again from the server. That way, you should see the writing on your Plugin it means it was installed.

Now all you have to do is start Minecraft… Press the button first… Multiplayer and then on that Direct access insert the Server address (for example, the local host) and the press Send.

In this way, you will correctly enter your virtual room. To check how the plugin works, simply press the button T on the keyboard, type the command /sitoweb and press the Enter the server. If he message with site url everything has been done correctly.

In addition, you can also see the list of active plugins on the server using the command /plugins. I mean, you successfully created your first plugin for a Minecraft Spigot server. Now all you have to do indulge yourself in using java code to create your own experiences within the Mojang title.

Since you are a fan of Minecraft, I suggest you also take a look at the page of my site dedicated to the game in question, where you can find countless tutorials related to the title of Mojang.
