Making Minecraft Game In Python With Code

Join My Realms SMP For MCPE 1.19 (Realm Code) – Minecraft Bedrock Edition

If you are not a game developer and do not have much experience with python just follow me carefully till the end. I will show you a step by step tutorial and you will have a python minecraft game running on your computer.

Before we proceed you need to have python installed and setuped on your computer and also a code editor if you dont have python installed follow this guide: Install and setup python.

Set Up Java Developer Kit

We will need to download the Java Developer Kit that will let our Minecraft Modding in Eclipse work correctly.

You can find the for JDK 8. The version of JDK you need is JDK 8 to work properly with Minecraft Modding.

The download page should automatically detect your platform and give you the correct download. The version I am downloading that is shown in the picture is for Windows 64-bit. However, you can click Other platforms to find versions for other operating systems. Click the Latest release button to begin your download.

Now the download of the executable file will start.

Once this is finished, find the file in your downloads folder and run the executable to install the JDK.

Run through the pop up window guide to install the JDK for your computer and click on each next keeping the default settings until the JDK finishes installing.

You will need to agree to the End-User License Agreement to continue.

Let Java run its installation until it is finished.

Now that JDK is finished, we can set up our code editor in the next step.

What Else Is Part Of The Code Builder Update

  • The Library Beta: Were shipping a beta version of the Library, a new feature that allows players to view and download worlds in-game without having to leave Minecraft and go to our website. You will see a new Library button on your home screen and a list of dynamically generated templates in your list of available templates when creating a new world. We also added the ability to deep link to content in the Library from outside the game, for example, here is a deep link to the Chemistry Tutorial world.
  • On-screen Control Guide: We know that, for some educators, using Minecraft: Education Edition is a new experience, and it can be challenging to get use to the game controls. Educators will now have a control guide directly on screen to get you up and running in a Minecraft world. These controls will update depending on how you use the game, and you can turn them off in the settings menu once youre comfortable using the controls.
  • Educator Resources: We also added an Educator Resources button on the home screen that connects users with professional development, training, lessons and community content on our website. In addition, if you are a new user or introducing Minecraft: Education Edition to your students, now you can find Education content in the games How to Play menu.

How Does Minecraft Teach Coding

When playing Minecraft, it is very easy for your kids to sink hours upon hours of their free time into its blocky world whether they are creating a small farming homestead in survival mode or planning out and building the biggest fantasy castle they can.

While this may seem like a waste of time to some parents, some have realised that this fun game is a great way to encourage kids to learn how to code while not making it actually feel like valuable and educational work.

But how does Minecraft teach coding?

In this short guide were going answer those questions and more, plus give parents a little more insight into how Minecraft coding could offer future career potential for kids.

Final Thoughts On Minecraft Hour Of Code

Microsoft and use Minecraft to teach kids how to code ...

Though aimed at children aged six and older, Minecraft Hour of Coding is worthwhile for anyone who wants to code. It’s for this reason that each tutorial has been designed for use both in a classroom and for individual use.

Minecraft Adventurer might be the only one available for offline use, but they’re all accessible online, regardless of your platform. After you complete each Minecraft puzzle, go back and solve them in different ways. In doing so, you’ll uncover additional hours of playability.

In preparing to write this article, I went through and began each Minecraft Hour of Coding. Each was exciting, fun, and yes, worthwhile. It comes highly recommended, regardless of your age.

Console Commands And Command Blocks

A more direct way of interacting with coding in Minecraft is through the Minecraft console commands. These are written commands that you can type into the chat box to make things happen in your Minecraft world. It allows players to do things like change the weather cycle, teleport to far-off places or create items that would otherwise be impossible to get. This in itself isnt truly coding, but it does teach an important concept about coding. Thats the idea that the things that we type into the computer can have an effect on the digital world in front of us.

In 2012 a new block, called the command block, was added to Minecraft that took console commands to the next level. These blocks can execute console commands in the game itself whenever certain requirements are met. When coupled with Redstone engineering, command blocks can introduce complex concepts like conditionals. This changes the commands found in the console into a kind of Minecraft coding language.

This Minecraft coding language doesnt work outside of the game, but it does a great job of introducing programming basics to new students.

How To Use Code Builder

It is easy to launch Code Builder in this new version of Minecraft: Education Edition. Once you open a world, simply press C on the keyboard. If youre using an iPad or touch device, select the Agent icon at the top of your screen.

You will have the choice of learn-to-code platforms when you open Code Builder. We are excited to continue our partnerships with Microsoft MakeCode and Tynker as we continue to evolve game-based coding with Minecraft. Read about updates to MakeCode here that accompany the Code Builder Update.

The Agent now displays its coordinates as you code. Find your Agent easily using the Agent Spawn Egg to make your lessons even more efficient. You can also target your Agent via commands and remove agents from the world .

The Code Connection companion application is no longer necessary with this update to in-game coding with Minecraft: Education Edition. For support on using Code Builder, visit the Help Center.

Is Minecraft A Good Coding Introduction For Kids

The real key to teaching a child coding is finding the right motivation. Minecraft offers that as it combines a fun game they love, with a gentle introduction to coding functionality.

The way Minecraft engrosses kids can be used to help engage them to learn about something useful in a fun way that doesnt feel like work.

Minecraft can be enhanced by modifications that are outside strings of code that changes the game from the inside, such as generating monsters, giving players increased health or items and even telling the non-playable characters to do specific things.

These mods are usually downloaded through a third-party website, with players sharing their own mods among the online community for everyone to use, but you can easily create your own mods to enhance your own gaming experience exactly how you want it.

Because of the relative simplicity of Minecraft as a game, learning how to modify it is a good steppingstone to learning to manipulate and create code for other games and programs.

How Do The Minecraft Hour Of Code Tutorials Work

Fix Minecraft Exit Error Code 255 on Windows & Mac

To date, there are four Minecraft Hour of Code tools for would-be coders:

  • Minecraft Adventurer
  • Minecraft Hero’s Journey
  • The latest, Minecraft Voyage Aquatic

With each tutorial, you learn the basics of computer science by programming a virtual character through a top-down view of the Minecraft world. For this, you use Blockly, a client-side JavaScript library for creating visual block programming languages.

Created by Google and released as open source under the Apache 2.0 license, Blockly uses linked blocks to write programs. As you drag and drop the boxes, you generate code in JavaScript, Python, PHP, or Dart. Blockly can also be customized to make the code in any textual computer language.

The first decision you make in your chosen Minecraft Hour of Code is selecting a character, Alex, or Steve. From there, the window splits into three parts.

  • On the left, you’ll find the Minecraft play space. It’s here where your program runs. Below this, you’ll see the instructions for each level of the tutorial.
  • The toolbox, in the middle area, is where the commands which control your character reside.
  • On the right is the workspace, where you build your program.
  • Each lesson works in the same way and begins with an introductory video. Let’s find out more about each Minecraft Hour of Code tutorial.

    Visit and make sure the version selected is the version for which you want to create a mod. In the large “Download Recommended” box, click on the small MDK box. A dialog box will appear, asking where you want to save the file, and what to name it. Choose any convenient location, but leave the name unchanged.

    Solution : Change The Java Executable Path

    If there are any issues with the working directory of Java, you may receive the Minecraft exit code -1. If so, edit the Java executable path in Minecrafts settings with these steps.

    Step 1: Open the Minecraft Launcher on the computer and tap Launch Options to continue.

    Step 2: Turn on the Java executable toggle.

    Step 3: Edit the Java executable path. The original path shows the Java filename as javaw.exe where the issue lies. You should modify the Java path as java.exe.

    Step 4: Tap on the Save button to finish the edition job.

    Learning How To Code Quickly Without Prior Experience

    This option is suitable for 99% of people. Even if you need an extremely large solution like Mineplex or Hypixel, you still need to understand at least the basics so you wont need to ping your developer team each time you need to change a simple message in the code for you.

    Coding is easier and faster than most people experience. The problem out there is a lack of quality resources, proven systems to follow and professional guidance to help you get unstuck. And as you probably know, if youre a beginner, youll get stuck a lot.

    Getting Started With Coding For Free

    Here are some great starting points for coding plugins. Minecraft updates rapidly and plugins break, so I really tried to write this article in an universal and future-proof way to avoid putting out a version-specific advice out there.

    Understand This Before You Start

    Minecraft is coded in Java. Everything we do will have to do with the Java programming language. If you never coded anything before, or you dont understand the Java programming language, you need to learn it before you can developer great Minecraft plugins. Yes, this tutorial is designed as a jumpstart right into production and we will not cover how Java works in general, but for most people you need to learn it simultaneously if you are serious about your progress.

    Getting Started Programming Minecraft In Python

    Complete latest Minecraft Hour of Code tutorial for chance to get ...

    The easiest way to get started programming Minecraft in python is to start with one of the simpler sample scripts. I recommend making a shortcut on your desktop to the scripts folder .

    You can load the scripts into IDLE. A fun script to modify is my water-filled donut script . For instance, change WATER to GRASS in the second last line to make a silly grass-filled donut. You can run this with /py donut from Minecraft, or just by pressing F5 in IDLE.

    Or to make a simple new script, create a file with your favorite text editor in the scripts directory. Put at the top:

    from mine import *

    This imports the needed library code. It also conveniently imports all the functions from the math library as well as names for all the blocks. Connect to Minecraft with:

    mc = Minecraft

    You can then send a “Hello world!” message to the user with:


    If you want to create a diamond block right under the player, you can also do:

    playerPos = mc.player.getPosmc.setBlock

    The coordinates for setBlock and getPos are measured from the player’s spawn point ).

    To run your script, save it and type /py helloworld in your Minecraft world and press enter.

    It’s sometimes useful to set a whole rectangular prism of blocks at one time: use mc.setBlocks. For instance, this excerpt from my script draws an 81×81 cube at the player position :

    length = 3*3*3*3mc.setBlocks
    import mcpi.minecraft as minecraftimport mcpi.block as blockimport mcpi.entity as entityimport math

    Can Minecraft Teach My Kid To Code

    Minecraft has proven to be a flexible platform for education. It has been used as a tool for teaching a myriad of concepts, so it makes sense to assume it would be useful for teaching coding to kids. And it is!

    Minecraft does a great job of providing an environment to learn coding in by giving students both a place to virtually meet with their educators and by visually showing them the effects that coding can have. But it isnt as simple as launching the game and letting the kids learn. Instead, it works best as one of many tools used in a more complete coding curriculum.

    As part of our interactive coding curriculum we teach our students how to create their very own games based off of Minecraft. Theyre able to learn programming in an exciting hands-on environment that does more than teach them the basic principles. It teaches them how to apply them. And unlike so many video-based programs, our coding classes for elementary, middle, and high school, are taught by live teachers so our students can get feedback on their projects in real-time.

    The main thing is this: Minecraft on its own will not be able to teach a kid how to code. Rather, it is a great way to build their interest in coding and can be useful as an educational tool in a well-crafted curriculum.

    Solution : Reinstall Minecraft

    If Minecraft exit code 1 still appears after trying the above methods, try reinstalling Minecraft. Likewise, you need to uninstall Minecraft first. Follow the steps below to uninstall and then reinstall Minecraft now!

    Step 1: Open the Run window, and then input control and hit Press.

    Step 2: In the next window, find and click Programs and Features.

    Step 3: Find and click on Minecraft from the list of installed apps in the next window. Then click Uninstall and confirm the operation.

    Step 4: After that, move to the official website of Minecraft to download and install it.

    Creating A Custom Block

    Setting up Block Registration

    Firstly, create a new DeferredRegister of type block which will be used to register any blocks. Make sure to import net.minecraft.block rather than any of the other options.

    publicstaticfinalDeferredRegister< Block> BLOCKS=DeferredRegister.create 

    Next, you need to register the method with the IEventBus parameter. If you have a separate ModBlocks class then add the following method to it, otherwise add it to your already existing register method.


    To create blocks easily add the following two helper methods to your class. registerBlock registers the block while registerBlockItem registers the associated item.

    privatestatic< TextendsBlock> RegistryObject< T> registerBlockprivatestatic< TextendsBlock> voidregisterBlockItem

    Finally, like with items add the register call to your main class.


    The following code shows how to add a simple block.

    publicstaticfinalRegistryObject< Block> EXAMPLE_BLOCK=registerBlock-> newBlock.harvestLevel.harvestTool.setRequiresTool.hardnessAndResistance))

    A Note About Mappings

    There’s Second Account?

    There are two different sets of mappings available for method names – “MCP” community-based mappings, and “Official” mappings based in part on the official Obfuscation maps . The default in the MDK has recently been changed to ‘official’, but this tutorial will use the MCP mappings for now because function parameter names are not available in the official mappings.

    Learn Minecraft Coding: The Ultimate Guide For Kids

    Ready to learn Minecraft coding? Today we’re going to guide you through everything you need to know about Minecraft coding for kids, and the ways it will benefit your child.

    Kids love playing games, especially Minecraft. If youve ever watched kids as they play games together in person, you’ve noticed they create their own rules and modify the game as they go. Perhaps you’ve heard your child lament that they wish they could add or change something in their electronics games.

    What if there was a way for kids to learn critical thinking skills, important computer science concepts and modify a popular electronic game, like Minecraft all at the same time? Lucky for you, there is!

    Set Up Your Text Editor

    Before we begin Minecraft modding, well need to download some tools.

    First, for this guide, we are going to download the Eclipse IDE, one of the most popular professional text editors for Java in the world.

    To download the installer and look for the Get Eclipse IDE 2020-06 Download area that looks like this:

    Find the executable file in your download file and open it to launch the Eclipse installer.

    When the launcher opens, select the Eclipse IDE for Java Developers.

    Then on the next window, keep the default install location and then click the INSTALL button.

    The next window will appear and you need to accept the agreement for Eclipse.

    Then the next window will prompt to make sure you accept the license Agreement.

    Checkmark the Remember accepted licenses box and accept the Eclipse Foundation Software User Agreement.

    Once this is accepted, you are almost done with the install.

    Just accept the Eclipse Foundation certificate as shown in the image below.

    Once this is done, Eclipse will be downloaded and ready for when we need to use it to write our code.

    The next step is going to be installing the Java Developer Kit which will let our code work properly with Minecraft.
