How To Install Minecraft Mods On Java Edition

The Ultimate Guide to Minecraft Modding with Java in 2022

In this Minecraft Modding tutorial, we will be providing you lot with footstep by footstep instructions on how to get started with Minecraft modding while creating an crawly custom Sword that you'll get to play in the game.

We'll be using Minecraft i.12.2 as information technology is the version uniform with our electric current Minecraft courses. Newer versions may use different setup instructions.

As a rule of pollex, Minecraft modern lawmaking is not compatible from version to version. For example, 1.12 mods volition not work with ane.13 and to a higher place.

You'll need a PC or Mac computer for this tutorial, as Chromebooks or mobile devices will not run the software properly.

At CodaKid we take taught over 50,000 students Minecraft coding, and have won numerous industry awards for online courses including a Parents' Pick Gold Laurels and CODiE Finalist for Best Coding and Computational Thinking Solution.

While we teach coding for kids, this guide tin be used by teachers, parents, or anyone with an interest in creating a custom Sword Mod for Minecraft Forge.

We promise that you bask this gratuitous footstep by stride guide to covering 1 of the first courses nosotros teach in our Minecraft Modding series.

Nosotros'll cover the very nuts of what you'll need to kickoff Minecraft modding, and you will acquire how to use Java, one of the virtually popular programming languages in the world.

Nosotros'll also teach you how to download and utilise the Eclipse IDE, a text editor used by professional  developers at companies such equally Facebook, Google, and Amazon.

Nosotros will continue to update this blog in the coming months and transition to more recent versions of Minecraft as they get stable for mod cosmos. Our next large form revision will take identify after the upcoming Minecraft Caves and Cliffs Update.

Stride 1: Gear up Java Developer Kit (JDK)

Nosotros will need to download the Coffee Programmer Kit that volition let our Minecraft Modding in Eclipse work correctly.

You can notice the download link Hither for JDK viii. The version of JDK you need is JDK 8 to work properly with Minecraft Modding.

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

Now the download of the executable file will start.

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

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

You will need to agree to the Cease-User License Agreement (EULA) to continue.

Let Coffee run its installation until it is finished.

Now that JDK is finished, nosotros can set upwards our code editor in the next pace.

Step ii: Prepare your Text Editor

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

Beginning, for this guide, we are going to download the Eclipse IDE, ane of the most pop professional text editors for Java in the world.

To download the installer CLICK Hither and await for the Become Eclipse IDE 2022-06 Download area that looks similar this:

Click the Download 64 scrap button and the next page volition appear where you can download. Click the Download button shown and wait for the Eclipse file to finish downloading.

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 Coffee Developers.

Then on the next window, proceed the default install location so 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 certain you accept the license Agreement.

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

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

Merely have the Eclipse Foundation certificate as shown in the image below.

In one case this is washed, 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 volition let our lawmaking work properly with Minecraft.

Step 3: Set up Forge

Adjacent y'all will need to download the one.12.ii version Minecraft Forge, every bit this will allow us to modernistic Minecraft 1.12.2. The instructions shown here should work for any Minecraft version from 1.12.ii onwards.

Yous tin find the download link HERE , and only follow the instructions we've laid out below.

On this page you should see the latest and recommended version for Forge. Download the Recommended version Mdk (Mod Development Kit) file for 1.12.2 as shown.

You lot'll be taken to Forge'due south advert redirect. You don't need to click on anything but the "Skip" push in the top-right corner, highlighted in red below.

Once this is downloaded, observe information technology in your downloads folder, right click on the zipped up folder and and so select Extract All…

On the next window click the Extract push button.

This is going to be our project folder. So we desire to make a copy and rename and motility it to a new location on our reckoner.

Nosotros recommend putting a re-create in your Documents folder or on your Desktop.

Correct click and copy and paste the unzipped forge binder in a location you desire and make sure to rename it to something descriptive.

In this example we will be naming it ForgePractice.

We have the Forge binder set upwards and are fix to create our new project!

Step 4: Install Pinta

Next we want to install the Pinta program we will apply to change the look of our Sword Texture.

Go the the link HERE to become to the Pinta download page.

On this page click the download link for the OS you lot are on Mac or Windows.

Once you lot accept the installer downloaded, open information technology upward in your downloads folder and run the installer.

Fully install the application and accepting whatsoever agreements forth the style.

Shut out of the installation when information technology is finished.

Now we have the programs nosotros need to create our mod.

The adjacent step is creating our project.

Step 5: Create Your Project

Launch Eclipse. It will enquire you to cull a directory to apply as Eclipse'due south workspace. This directory needs to be outside of your projection folder. I recommend creating "eclipse-workspace" within of your Documents folder. You tin also just employ the default location Eclipse gives yous.

Eclipse will now open up. Close out of the Welcome tab.

In the Bundle Explorer, click on "Import projects…"

In the "Import" window that pops up, select "Existing Gradle Project" and click Adjacent.

On the adjacent page, click "Browse…" and select your project folder. Click "Select Folder".

Y'all should now come across this. Click Finish. It should close later importing the project.

You should now see your default workspace view:

Go into the Gradle Tasks tab at the lesser of the window. It looks like this:

Expand the "fg_runs" job binder, and double-click on genEclipseRuns to run the task to ready our Minecraft launch configuration. Once it'due south finished running, we need to import our new launch configurations.

Go to the File menu of Eclipse near the meridian of the window. Click it, then click Import in the carte that appears.

Click the arrow next to Run/Debug in the carte du jour that appears. Select Launch Configurations and click Adjacent.

In the next menu, checkmark the box next to ForgePractice (or your binder name if you named it differently). It should show the runClient and runServer configurations selected. Click Finish.

Just one more edit earlier we can run Minecraft. Click the arrow side by side to the light-green Run button. Click on Run Configurations. You can as well find this from the Run card at the height of Eclipse.

Become to the Surround tab in the new window that appears. Get to the MC_VERSION line in the list.

Double-click on the ${MC_VERSION} value and alter it to one.12. And then click Run. Your Minecraft should at present launch from Eclipse.

You lot tin can close out of the Minecraft Client; yous should now be able to run the game just by clicking the green "Run" button in the toolbar near the pinnacle of Eclipse.

We are now fix to start Creating a Mod and learning Java!

Pace 6: Make Your Own Mod – A Custom Sword!

Finally our Minecraft modding tutorial begins!

In one case Eclipse is loaded up and opened, nosotros are ready to start typing in java code.

Let'southward open an example Mod java file that is provided for us that nosotros volition exist starting from.

On the left side of the window, open the projection folder by clicking the arrow next to the name. Your project folder will likely exist named with the same name you gave to the folder in Documents.

Now open up the "src/main/java" folder and then open the "com.example.examplemod" file and inside you will find ExampleMod.java.

Double click this to open up up this java code file.

This file contains our starting lawmaking. It contains our mod ID and name. The first thing nosotros desire to do in ExampleMod is find the lines that define our MODID and Proper noun.

Alter the MODID to sword making certain it is all lower case.

This is the unique ID for our mod nosotros will brand.

The Proper name is the name of the mod equally it will appear in Minecraft.

Name this what you prefer.

Make sure these are inside quotation marks because they are String variables.

Strings are variables that are words or characters.

(We will be covering variables in a little bit).

Become to the src/main/resources binder and open up the mod info file.

Open mcmod.info here and change the modid to "sword" and change the proper name, description, author, and credits to whatever you lot like.

Make sure these are inside quotation marks again every bit they are Strings that will be read by the code.

The next pace is to create variables for our ToolMaterial and sword.

Place these lines below the private static Logger logger line in ExampleMod.java.

Variables are helpful in code because they act as boxes with names that store information within of them we can utilise easily.

What we are doing here is nosotros are creating to variables myToolMaterial and mySword.

The types of variables are the ToolMaterial and Item.

Once we take the variables created, we demand to import the code files that define what a ToolMaterial and an Item practise.

We tin do this by mousing over the blood-red fault lines underneath ToolMaterial and Particular.

In the dropdown listing that appears, import the code shown.

Start with the ToolMaterial as shown below.

Adjacent import the Particular every bit shown below.

At present because we are making a customized sword in Minecraft, nosotros need to define what the cloth is for the sword tool is we will be using.

This is where we define our custom tool material variable nosotros created.

Get into the preInit function shown and inside below the logger line, write out  the myToolMaterial line shown.

What that line does is it fills in our myToolMaterial variable with data on what the material does for tools we apply information technology on.

We will be applying this tool fabric to our sword. Just let's actually fill in the name, harvest level, damage etc.

Change out the proper name to a String variable that is the textile name.

Yous tin can name this whatsoever you like.

The harvest level indicates which minerals it tin get resources from.

If we practical this material to a pickaxe, this is where we would define if it can become diamonds from Diamond Ore.

Putting this at 4 lets it mine whatever we want it to.

maxUses is how many times we can utilize it before it breaks, the efficiency is applied for harvesting tools for how quickly information technology will mine or harvest a block.

The damage is how much impairment it will exercise when yous striking an entity with it.

The enchantability is related to how easy information technology is to enchant.

After this material line add in a definition for what our sword is.

This line defines the sword every bit a new class chosen CustomSword.

We need to create this new class and we practise that by mousing over the red mistake line and clicking

Create class 'CustomSword'.

A new window will open up, keep these values at the default settings and just click Cease.

This volition create a new Java code file CustomSword and automatically open it upward for information technology.

This is a Form which is code that defines what the CustomSword is and how it behaves.

What is convenient for the states is nosotros can make sure to change the import and public class lines to say "ItemSword" instead of "Item" and this defines our class with all of the data that already exists for swords in Minecraft.

This lets us swing it and damage creatures equally well as pick it up and drop it and any pocket-sized interaction a sword will have in the code.

At present what we demand to do is add a constructor for our class.

This defines how the sword is made. Call up of it as how blueprints are used when creating buildings.

We are defining specific rules for how our sword volition be created.

Once the constructor is added in, change it to remove the Fabric reference in the parentheses and then fill in our ExampleMod.myToolMaterial.

After these changes are fabricated, nosotros demand to set the RegistryName, UnlocalizedName, and CreativeTab for our sword.

The Registry and Unlocalized names of our sword need to specifically be "my_sword" because these are the names our code uses to identify our sword and link our texture to it.

The CreativeTab can exist inverse to the tab you desire the sword to appear in.

Nosotros chose Combat but in that location is a list that will appear where you can cull the tab you desire your sword to be in.

Once this is washed, our class is set up to go.

We need to create a new java class that we volition use to annals our sword into Minecraft.

Go to the Package Explorer on the left side of Eclipse and right click on the com.example.examplemod package and create a new Form (equally shown below).

This will open the course window nosotros saw earlier.

This time we want to name it CommonProxy and so select Finish.

Now we want to go above the public class CommonProxy line and write the @mod.EventBusSubscriber.

This will let the grade be run during the loading of Minecraft then it tin annals our sword into the game.

We need to import the code for modernistic but like how nosotros imported Item and ToolMaterial earlier.

Once that is imported, we need to create a new function that volition run specific lawmaking to register the sword Particular in Minecraft.

Brand certain to include the ExampleMod.mySword within the registerAll() parentheses because this tells the annals function specifically to annals our sword detail.

Now nosotros need to import the code that is missing from this Class.

We need to import SubscribeEvent, RegistryEvent, and Item.

Just like before, we are importing lawmaking that already exists to assistance u.s.a. with our register code.

Get-go with SubscribeEvent as shown below.

Next Import RegistryEvent equally shown below.

Finally, Import Item (cyberspace.minecraft.detail) as shown below.

Once these imports are done, we can actually examination out or "sword" except it will not look like a sword only yet.

In social club to examination out our code, make sure you are clicked inside a lawmaking window and then get up to the green play button and printing it simply once.

Make sure you lot press the button that is just the green push button and not the ones with little icons in the corner.

After some time, you should meet a window start opening Forge Minecraft.

Wait until information technology fully loads Minecraft to its main menu.

One time y'all have finished waiting, select Unmarried Histrion at the principal menu.

Next, select Create New World to start setting up a Creative manner game.

Then modify the game mode to Artistic and alter the name, then select Create New World.

This will open up the new world and accept a bit of time to open the Minecraft world.

Once the globe is opened, click the "east" button to open the Creative Tab inventory.

Become to the Gainsay tab or whatever tab you picked when we set the Creative Tab in our code.

Scroll to the lesser of the tab and make sure y'all have your sword.

We will be updating the look and the name only if you put it in your inventory, you lot will have a sword that will function as we coded information technology to!

Once you are done testing your purple and black block sword, let's go back to our code to make the model and texture linked up in our lawmaking.

Leave out of the Minecraft window and open CommonProxy.java and add together a new registerRender function inside of the CommonProxy class as outlined below.

This will annals the model for the sword based on the item nosotros want to annals.

Nosotros will link this to our sword in the next couple of steps.

We now demand to import more code.

Make sure to import ModelLoader and ModelResourceLocation.

Start with ModelLoader.

Next, Import ModelResourceLocation as shown below.

At present let's render our sword!

Make a registerRenders part that nosotros will register our ExampleMod.mySword variable.

Now nosotros need to import the ModelRegistryEvent code then our models will properly render in Minecraft.

Now nosotros need to name our sword.

Right click on the src/main/resources and brand a new untitled Text file inside.

Now add in a code line that will name the sword.

You lot tin can customize the name of your sword by changing the proper name to the right of the equals (=) symbol.

At present let's save this untitled filed.

Get to File > Save as and a window will open asking you to select the location of the file.

Select the MDKExample>src>primary>resources folder and change the file name to be en_us.lang so click OK to make the file

Now we need to make our sword texture and import it into our project.

I have a picture of an Iron Sword in Minecraft below.

Get alee and right click on it and select "Salve image as…" and so save the file as "my_sword.png".

It is a small file because Minecraft needs a smaller prototype.

Once you have it saved, right click on the pic wherever information technology is saved on your computer and so copy it.

One time information technology is copied, let's detect the folder nosotros need to paste information technology in.

Go to our project folder ForgePractice and open the src > primary > resources folder and paste in the my_sword.png into here.

Now render to Eclipse and add together a new Text file into the src/chief/resources folder like nosotros did before.

In this new file, blazon in code that volition define the particular sword resource.

Nosotros will now save this file as a json file and so go to File > Save as and save the untitled file as my_sword.json within of MDKExample > src > primary > coffee > resource.

Now click the pocket-sized dropdown Triangle next to Parcel Explorer and alter the Bundle Presentation to Hierarchical. We do this because nosotros will be calculation in more packages to organize our code and set it upwardly then our sword files tin exist properly managed by our code.

Now we need to create Packages for our resources folder.

Right click on this folder and add a New Parcel.

In the popular up window, proper noun it assets.sword then click Finish to create the package that will concord our other three packages.

At present right click on avails.sword package and add a New Package.

In the pop up window name information technology assets.sword.lang.

Now brand ii more packages inside of avails.sword.

Name these "assets.sword.textures" and "assets.sword.lang".

One time these are made, drag in the en_us.lang, my_sword.json, and my_sword.png to their respective folders as shown in the prototype below.

The final matter to do is customize our sword.

Open Pinta past searching for Pinta in our search bar and opening the Pinta plan.

With Pinta opened, become to File > Open where a new window volition open up.

Let's now find our sword imagine in our project folder ForgePractice > src > main > resource > avails > sword > textures > items.

Now we demand to actually pigment the sword!

Zoom all the way in and turn anti aliasing to the off position and change brush width to 1. All of these settings are highlighted in the paradigm beneath.

Now all you need to do is paint your sword and erase or add together anything you lot want.

Use the colors, the brush, and eraser tool.

Make certain to change your eraser anti aliasing and brush width as needed just like what nosotros changed with the paint brush.

Then paint your sword to await like whatsoever yous want! If you lot make a mistake yous can hold downwards CNTL then printing down on Z to undo changes. On a Mac, yous'll hold down the Command button and press down on z.

In one case y'all are done become to file > Save and make sure the new changes are saved y'all made.

In one case this is all finished we are washed with our custom Sword mod!

You can at present test it by clicking on the Green play button just like what we did earlier!

Make sure everything is perfect and as you lot want it so get ready to Compile your Mod and test it in Minecraft.

Stride 7: Compile your Mod

Now that our code is finished, we need to compile and build our mod.

In order to build it, nosotros need to go to the projection folder we fabricated and right click in an open space and select "Open Powershell window hither" or "Open command window here".

Once the window is open up, write in the command "./gradlew build" and press Enter to run this command.

Then await for the BUILD SUCCESSFUL bulletin to display.

Once this build is finished, render to your project folder ForgePractice and open the build folder.

Brand sure y'all meet modid-1.0.jar.

This is our build modern file!

Now in the next step nosotros volition show you how to load your Mod onto your Minecraft game.

Pace viii: Exam your Mod!

At present to test our modern we demand to make certain nosotros take regular Minecraft forge downloaded.

What we were working in was the developer kit for Forge.

At present nosotros need to access the Minecraft Forge customer.

Return to the same Minecraft Forge download page nosotros were at earlier.

Now in one case at this folio click the regular install button shown.

Once the download finishes, open up the executable file in your downloads folder.

Once this launches, you lot should encounter the Forge install window.

Make certain y'all have Install client selected, and proceed the default location and and so click OK.

Make sure the Forge client installs successfully and then press OK when it is done installing.

One time Forge is done installing, we need to discover our build mod file in our Eclipse project binder.

Open your ForgePractice binder.

So open the build folder and find the libs folder in hither.

This is where our Mod will be.

Right click and rename the modid-1.0.jar to what you desire.

Once it is renamed, go ahead and right click and copy the new jar file.

Once the jar file is copied, we demand to open the folder that has our mods in it.

Get to the search bar and type %appdata% and open the folder that shows upward in the search.

When this folder is open, become to and open the .minecraft folder.

Inside this .minecraft folder, you should see a mods folder, open up up this folder.

Next, paste in your modernistic we copied earlier.

Your mod is all gear up up to work in Minecraft!

Now we need to launch Minecraft and open up the Forge version. Search and Open the regular Minecraft version.

This has to exist the Java version of Minecraft.

The Windows 10 or a mobile version of Minecraft will not work.

Once the Minecraft Launcher is opened, become to the Launch Options tab and click Add together new.

In the Add New window, Change the version to the release 1.12.2-forge version.

Name it Forge 1.12 or something descriptively like.

Become back to the main Minecraft News tab and click the driblet downwards arrow next to PLAY and select the new Forge 1.12 launch version nosotros made.

In one case this is selected, click PLAY to launch the Minecraft Forge version.

Once Minecraft is loaded, we need to brand a new level just similar what we did when testing our sword.

Go to Unmarried Player and so Create New World only like we did earlier.

In the settings, alter it to Creative Manner and change your World Proper noun.

Once all of this is done, click the Create push and wait for the new Minecraft game to load.

Only like earlier, observe your sword in the Creative Tab by clicking "east" on your keyboard and so head to the tab y'all set your Sword to announced in.

Mine is the Combat tab and equally yous can see, the custom sword is at the bottom of the listing of items.

Yous've officially created your own Minecraft Modern from scratch and loaded it into your own Minecraft game!

Congratulations!

You lot can brand some other sword using the same techniques or even challenge yourself to create an Axe or other tool.

What Can Kids Mod in Minecraft 1.12.two?

When it comes to creating Minecraft mods, a sword (or even weapons in general) is barely the tip of the iceberg. Y'all can create so many awesome mods with the Java Developer Kit, Eclipse IDE, and Minecraft Forge. From mods that add thousands of new weapons for yous to observe and exam out in-game to mods that add new cities and new adventures, the sky is literally the limit with Minecraft.

Here'south a quick overview of some of the most popular i.12.2 Minecraft mods, so you can see (i) how creative Minecraft players tin be, and (2) how you can modernistic almost anything imaginable:

Minecraft Lumberjack – a mod that instantly clears away anything wooden in its path (trees, leaves, logs, etc.)

JurassiCraft mod – a mod based on the Jurassic Park and Jurassic World franchises. Create in-game dinosaurs by extracting Deoxyribonucleic acid from fossils and amber!

i.12.2 MoarFood Remastered – a modernistic that adds 100+ new and unique types of food

Minewatch Mod – a mod that combines Minecraft with another popular game, Overwatch. Information technology adds playable heroes and usable weapons and armor that follow the await + functionality of Overwatch items.

Five Nights at Freddy'south Mod – a mod that adds new blocks, items, and mobs based off of the characters from another game, Five Nights at Freddy's

TelePad Mod i.12.two – "teleportation made easy!" A mod that allows players to travel over dimensions, dorsum and forth

Item Filter Mod (Advanced Filtering Items) – a practical mod that allows you to add specific filters with the API. This is perfect if yous're trying to rummage through thousands of in-game objects in your inventory

Extra Alchemy Mod – a mod that adds hundreds of new useful potions

Xaero'south Globe Map Mod (Trace Your Footsteps) – a Minecraft 1.12.two modern that introduces a self-writing fullscreen map to your customer. Changes depending on the world/dimension/server

PetCraft Mod 1.12.2 – this modern adds a multifariousness of pets (i.e., dogs, cats, hamsters, etc.) to the game

Guns Mod | Modern Edition – adequately contempo modernistic that adds modern guns (i.e., pistols, shotguns, SMGs) to the game

UFO Mod 1.12.2 (Alien) – exactly as the name suggests; this mod introduces a full-blown UFO invasion into the Minecraft world

Yeah, all these are real mods, and, yes, they're all functional. Created by Minecraft players for Minecraft players, Minecraft modding is honestly one of the best ways the community keeps engaged with the game.

Believe us; once you've gotten used to mods, vanilla Minecraft may seem nigh limiting (which is crazy, because Minecraft remains i of the most intuitive and all-encompassing sandbox games of all time) in comparing. So when you outset creating and downloading mods, we highly recommend you organize your mods folder. Information technology's very hard to end at just a few!
