How To Mod Minecraft On A PC

If you’ve been playing Minecraft for a while and are starting to get a little tired of the game-play, then it’s worth considering getting into modding. Modding, put simply, refers to the practice of altering the coding within the game in order to generate different sprites to change the features of the game.

Mod Minecraft On A PCIn order to get into modding, it’s important to know exactly what we mean by the term. Mods are alterations to the coding of the game. These changes can add features such as music, game themes, improvements to fix bugs, hidden prizes, increased drop prizes and different monsters. To be frank, the possibilities are pretty much limitless.

The process of modding requires you to install third-party software on your device. This can be dangerous. Care should always be taken when installing programs from unknown sources. Mod packages can contain viruses, so a good anti-virus program is a must for those wishing to get into the modding scene.

It’s important to stick with trustworthy sources such as ‘Best Minecraft Mods Pocket Edition’ by Minecraft Books. Also, it is important to save the original copy of your Minecraft before you modify it, just in case your mod messes up.

Some important programs you will want to have in order to create your mods include:

  1. Java Development Kit (JDK) – where you place code to change Minecraft
  2. Notepad, Notepad ++, or another text editor – where you write the code
  3. Integrated Development Environments (IDEs) – increases coding speed Examples: Eclipse, IntelliJ IDEA, Oracle NetBeans
  4. Mod Coder Pack (MCP) – changes code to readable source code
  5. Zip extraction – such as WinZip, zipRar, 7Zip, WinRar etc.

Other important programs to assist in modding Minecraft are:

  1. Java Runtime Environment (JVE)
  2. Forge (an Application Programming Interface or API) – allows for multiple mods to run at once.

There are some important steps to make before attempting to mod. These will help the process run more smoothly:


To install the JDK, go into the JDK folder (which also might be combined with the JDE) and enter into the .bin folder within the JDK folder. Copy the file path. Go to your ‘Computer Properties’ folder and click on ‘Advanced System Settings’. Under the ‘Advanced Tab’, click on the ‘Environmental Variables’ button.

Under ‘User Variables’, click on the ‘New’ button. In the ‘Variable New’ column type ‘PATH’. If you already have this user variable, then edit this one. In the Variable Value, enter the copied script followed by ;%path%.

It’s important to make sure there are no spaces. When editing, place the same criteria at the end of already written script with only a ; between the script leaving no spaces. Click ‘Okay’ in the ‘New User Variable’ window and the ‘Environmental Variables’ window.

Close the other windows. Check the JDK runs properly by opening a command prompt and typing javac. The first few lines should read: C:\Users\username>javac

Usage: javac Msource files>Where possible options include:This is followed by a list starting with -. If this is not the case, then refer to Koene 2015.

Eclipse LogoEclipse:

Download the program from Make sure it is the correct bit-version for the correct operating system.

Extract file. Create a folder for it to be saved to on your desktop where the rest of your Minecraft coding project can be kept.

Minecraft Forge:

How to Mod Minecraft on a PCDownload the program from Make sure you get the right src version and to wait for 5 seconds after finding it before you click a red button on the top right which according to Koene 2015 is the best version.

Unzip the file and save it in the ‘new mod code’ file that was just created.

Look through the Forge folder. If a gradlew.bat is not there then the correct version was not downloaded.

Run the command prompt: gradlew setupDecompWorkspace eclipse

The code will read something like


Total time: 11 mins 9.252 secs

After the command prompt finishes it will be ready to start coding.

Final stages:

Open Eclipse. Workspace Directory will open. Click Browse. Select the Eclipse Folder within the folder where Forge was saved.

Click ‘Ok’ in the Workspace Launcher window. Now the Project Minecraft will appear. If you click on the folder it will expand to show files including the mod file where you put either your personal code mods or mods found from the internet.

Creating or adding mods

To learn more about creating your own mods read Koene 2015. Otherwise, other platforms exist in which mods can be downloaded.

All you have to do is:

Download launcher from specific website. Copy link of mod website platform from website. Go to Minecraft folder and press on the add pack button on the left side of the screen. Paste the link.  It will download and then you are good to play.

The last thing to remember when creating or downloading mods is that:

Every time Minecraft updates, you will have to re-download the mod and/or update it.
