Getting started

Note: This tutorial should take around 1 to 1.5 hours to complete.

Resource packs can modify textures, models, animations, music sounds, user interfaces, and languages.

What not to do

There are some things that you should not do before creating a resource pack. Here is a list of "don'ts":

  • Don't do anything that violates Mojang's terms of use for Minecraft.
  • Release Minecraft versions or modifications that allow you to play without having bought Minecraft from Mojang.
  • Release the decompiled source code of Minecraft in any way.

Creating a resource pack

Start off by navigating to our resourcepacks folder. To find the folder, you must first locate the Minecraft folder. Once you are in the resource pack folder, create a new folder and name it: “Tutorial_Resource_Pack”. Then, open that folder.

The first thing we need to do is create a pack.mcmeta file. This lets Minecraft know that the folder is a resource pack and it also allows you to customize the description that appears when you're selecting which resource pack to use in the game.

Creating an MCMETA file

To create an MCMETA file, right click in the 'Tutorial_Resource_Pack' folder and create a new text document. Name this file “pack.mcmeta”.

Requirement

  • Any text editor should work but the suggested is a text editor using some sort of programming IDE.
Note

Make sure the file extension is .mcmeta and not .txt when you rename it. You may be warned that changing a file name extension could make the file unusable. This is okay!

If you can’t see file extensions, you can turn them on by going to the View menu of the file explorer and checking the check box for file name extensions.

pack.mcmeta

Open pack.mcmeta in a text editor of your choice and copy or type the following (You should change "pack_format" depending on your Minecraft version):

pack.mcmeta
{
   "pack": {
      "pack_format": 4,
      "description": "Tutorial Resource Pack"
   }
}

"pack_format" requires

(In pack format 3 and higher (1.11 and higher) all of the file names in the resource pack should have small letters only)

You can leave the description or you can change it to something more exciting. If you decide you need something with fancy characters, you can look up the code for it here. Say you want to use the letter thorn: Þ. You'd put that in as \u00DE. Just make sure you use a backslash and not a forward slash. (Only the characters 0000-FFFF (BMP) are supported in Minecraft)

Note

This file is written in JSON! We won’t go into specifics about the format now, but be aware about how things are laid out. Be very careful not to forget quotation marks, colons, and curly or square brackets. Missing one of these can lead to your resource pack not working correctly!

Testing our Pack

Now we are ready to test it out in game! Launch Minecraft and open the options, then click on Resource Packs. Your game should look something like this if you used the above code:

Troubleshooting

If you don’t see your pack in game, make sure your pack.mcmeta is correct. If it isn't, look for any missing curly brackets { }, commas, colons :, quotation marks “”, or square brackets [ ]. Remember for each open brace, quotation, or square bracket, you must have a closing brace, quotation, or square bracket.

Pack icon

If an icon is not specified, a cobblestone icon will show up next to the pack. Any image can be used here, as long as it is called pack.png. The pack.png file must be 64 x 64 pixels for your custom image to render properly.

Modifying an Entity’s texture

Now that we have our resource pack set up, let’s modify the creeper's texture!

However, before we can do some painting, we need to set up the folder structure that Minecraft expects resource packs to be in. To do this, do the following:

  1. Create a folder named “assets” in our Tutorial_resource_pack folder
  2. Inside “assets”, create a folder called “minecraft
  3. Inside “minecraft”, create a folder called “textures
  4. Inside “textures”, create a folder called “entity
  5. Inside “entity”, create a folder called “creeper
  6. Copy the creeper texture from the Vanilla Minecraft resource pack into our newly created creeper folder. (Note: You will need to use a file archiver, such as 7zip, to extract the files for the Vanilla textures. Located in Windows as: C:\Users\name\AppData\Roaming\.minecraft\versions\1.13 and extract the .jar file. In the new folder locate assets\minecraft\textures\entity.)

Now that we have the normal creeper texture, open it up in the image editor of your choice. It should look something like this:

CreeperTexture1.png

You might notice your texture looking small, make sure to zoom in on the texture. In MS Paint you can control magnification in the bottom right hand corner of the window with the slider.

CreeperTexture2.png
A quick note on textures

If you’ve never seen a texture before, the above image might surprise you. The best way to think about it is like wrapping a gift with wrapping paper, but instead our wrapping paper is our texture. Here is how the creeper’s texture is laid out:

TextureLayoutMap.png
Image Key
Top Top of cube
Bot Bottom of cube
Left Left side
Frnt Front side
Rt Right side
Bck Back side

Areas with matching colors face the same direction (i.e. Red areas are always the front of a cube).

How this looks in game:

Now it's time to be creative! Edit the creeper however you want. I’m just going to add a headband for sake of simplicity.

Once you are happy with your texture, save out the file as a .png and make sure that the file name is “creeper”. The game will only look for files with the correct name.

Modeling Blocks/Items

Sometimes you may want to change one of the Minecraft models. Here is a quick and easy way on how to do it.

Requirement

  • A 3D Modeling Editor like Paint.net. You can use other modeling editors but it is recommended to use this because it is easier to use and can export to .json format.
  • A ZIP viewer like WinRAR for Windows. Other ZIP viewers can be used but this can view JAR files as well.

Replacing a Block

Because the default ladder in Minecraft isn't 3D, you can replace it with your own model. First, get all the ladder's files into this resource pack:

  1. Open the Minecraft JAR file using a ZIP viewer of your choice.
  • Navigate into the assets/minecraft/blockstates folder, then extract ladder.json to Tutorial_Resource_Pack/assets/minecraft/blockstates
  • Navigate into the assets/minecraft/models/block folder, then extract ladder.json to Tutorial_Resource_Pack/assets/minecraft/models/block
  • Navigate into the assets/minecraft/models/item folder, then extract ladder.json to Tutorial_Resource_Pack/assets/minecraft/models/item
  • Lastly, navigate into the assets/minecraft/textures/block folder, then extract ladder.png to Tutorial_Resource_Pack/assets/minecraft/textures/block.

Now you can either edit the ladder.png using your preferred image editor, or you can edit it in your preferred modeling editor.

Modeling the Ladder

In modeling the ladder, we will use the recommended Blockbench. To open it, simply double-click it. After it has opened, press Ctrl+O to open the ladder model. After the open dialog has appeared, go to the location where you saved it and double click.

You then should be facing a ladder which is on the south side of the box.

  • On the menu bar, go to “Edit -> Add Cube" to create a new block.
  • Resize the model to as small as one of the rungs of the ladder. Then, under Textured on the left panel right click ladder.png, then click Apply to Untextured Faces.
  • Use the area above to move the area of the texture to where you want it to be. Repeat until all sides of the block are as wanted.
  • Press Ctrl+S to save in resourcepacks/Tutorial_Resource_Pack/assets/minecraft/textures/blocks/ladder.png (Replace "blocks" with "block" for 1.13 and above).

Now we have created the particle texture of the block when broken and the main texture.

Finishing off

When you have completed the 3D model of the ladder and saved it, launch Minecraft, and test it out. Place a ladder on a wall, and you should see its replaced model.

Adding Languages

You can add new languages to Minecraft using a resource pack. Assume your language code is 'LANG'[1] and country/region code is 'COUNTRY'[2], pack.mcmeta will look like:

pack.mcmeta
{
   "pack": {
      "pack_format": 3,
      "description": "Tutorial Resource Pack"
   },
   "language": {
      "LANG_COUNTRY": {
         "name": "Tutorial Language",
         "region": "Country/region name",
         "bidirectional": false
      }
   }
}

If you want your language to be right-to-left, set "bidirectional" to true.

Then, put LANG_COUNTRY.json in assets/minecraft/json inside your resource pack. When you launch the game, choose your resource pack, open the Language selection screen, and your new language will be there.

Notes

The pack.mcmeta goes in the root folder of your resource pack, not in the assets/minecraft/lang folder. Also note that the above pack.mcmeta is the same file as the pack.mcmeta file that you have created a while ago. As of Java Edition 1.7-pre,[verify] you can choose multiple resource packs at once. If you want to use your new language and resource pack for before 1.7, you need to combine them manually because multiple resource packs could not be selected before the version.

Animation Properties

An example of an animation file is this:

stone.png.mcmeta
{ 
   "animation": {
      "interpolate": true,
      "width": 1,
      "height": 7,
      "frametime": 1,
      "frames": [
         {
            "index": 0,
            "time": 0
         },
         1, 2, 3, 4, 5, 6, 4, 2
      ]
   }
}
Note

All you really need to make a texture animated is the following code, though it will make each frame last only one frame:

stone.png.mcmeta
{
  "animation": {}
}

Save the file as the same name as the texture you want animated with an .mcmeta in the same folder as your texture.

Texture Properties

An example of a texture property is this:

shadow.png.mcmeta
{ 
   "texture": {
      "blur": false,
      "clamp": true
   }
}

Fonts

Character sizes in fonts are determined by the last line of pixels that contains pixels which contain a non-zero alpha. This allows additional padding to be added around characters by adding a color with an alpha level of 1, which Minecraft will consider as part of the character.

Testing your Resource Pack

  • Launch the game
  • Click on Options
  • Click on Resource Packs
  • Find “Tutorial Resource Pack” in the list on the left and click the arrow next to it
  • Click Done

If you decide you want to make some changes to your resource pack, just close the game, edit your resource pack, relaunch the game, and follow the steps above to test your resource pack again.

Packaging Resource Packs with Worlds

For using in singleplayer worlds, you can package your resource pack as a ZIP file named resources.zip inside the world directory. This will then be automatically used when playing the singleplayer world.

Server Resource Packs

If you are the owner of a server, you may set it as the resource pack of your server.

  1. Make sure, that your pack format is a .zip-folder.
  2. Upload the pack on a filehosting website, for example Dropbox(https://www.dropbox.com).
  3. Copy the download link of your pack. IMPORTANT: It has to be the direct download link, as an example for Dropbox the URL will end with "dl=0" If you're using Dropbox, all you have to do is changing it to "dl=1".
  4. Open the server.properties with a text editor.
  5. Search for the line "resource-pack=".
  6. Paste the download link behind the equal sign.
  7. Save your changes to the server-properties and restart your server.
  8. Enjoy!

Servers can have an icon that will show up in the Multiplayer list.

  1. Create a PNG image with a size of 64 by 64 pixels, transparency is supported.
  2. Save (or rename) it to server-icon.png.
  3. Move it to the server's directory.
  4. Restart the server.
  5. Server icons will display next to the server name.
