Tutorial:Creating a resource pack

Resource packs allow users to include files that can modify or add custom textures, models, animations, music, sounds, user interfaces, and languages that change the way some things in Minecraft behave, look or sound.

There are some things that you should not do when creating a resource pack / texture packs, which includes but is not limited to:

• Anything that violates the Minecraft EULA.
• Release files that allow users to play a release of Minecraft without having purchased it from Mojang.
• Release the decompiled source code of Minecraft in any way.

In any case, you should always follow the Terms and Conditions on the Mojang Studios website.

Minecraft has a unique mechanic that allows for text and media files to be added to the game files that allow for everything from custom block textures and models to custom credits and sound events. This tutorial is meant to help with setting up the file systems in order to implement them. Since the files are essentially code, there are technical rules for how to format files and certain things may change from version to version. As such, what is written in this tutorial may not apply to every situation, but in the case where the difference is significant and specific, it provides a framework on the changes needed for different versions.

Note: This tutorial is geared towards 1.21.9 and 1.21.10. It may be compatible with another version, but compatibility is not guaranteed.

Creating custom files for Minecraft: Java Edition, whether in the forms of resource/data packs or mods, is somewhat technical and can be difficult. There are many rules that must be followed in order for add-ons to work correctly, most notably how the files are formatted. There are many tools that can help mitigate these issues, some of which are listed here.

To access the base assets of Minecraft to edit textures, models, or sounds, a file archiver is needed. On Windows, 7-Zip is suggested. MacOS has a built-in file archiver called "Archive Utility" that can be used, but if an alternative is wanted, The Unarchiver can also be used. You can also make a copy of your target version's .jar file and replace the extension with .zip to open it in your system's native file browser.

Making a resource pack involves creating JSON text files, which can be tricky to use and format correctly, especially for people who have never had any contact with this format before, and are coming across it for the first time while trying to create resources for Minecraft. Fortunately, many file editors assist with formatting these files and making sure proper syntax is used. Here are some suggestions:

• Notepad++ - A very lightweight and easy-to-use text editor for Windows
• Visual Studio Code – More complex code editor better suited for those who have experience with working in such editors, it also comes with optional plugins you can download for syntax support
• jsonformatter.org – A web application for JSON formatting

In order to add sound files, you must put it in the proper format (.ogg). While this can be done using one of numerous sites online, an audio editor program is suggested to allow customizing or trimming of audio files. Audacity is one of the most popular audio editors.

To add textures or custom models, it is suggested to use a modelling program that allows for a visual-based editing system. Like with audio conversion websites, there are many online tools, though a common recommended program is Blockbench. Most image editors suffice to modify textures, but it is recommended to use an editor that supports transparency such as paint.net or https://pixlr.com/ so that you may add transparent pixels to textures.

All the resources and instructions in a pack reside in the pack folder, which lives in the "resourcepacks" directory.

In versions 1.11 and higher, all file names within a resource pack must use lowercase letters only.

A resource pack needs to follow a specific folder structure. Every content in your resource pack has its own place.

 └── minecraft
 ├── lang
 │ └── en_us.json
 └── textures
 ├── block
 └── item]]: Metadata of the resource pack. This is the only mandatory file.

To create this file, right click within your resource pack folder and create a new text document. Name this file pack.mcmeta.

Note: Make sure that the file extension is .mcmeta and not .txt when you rename it, as otherwise the resource pack will not be readable by Minecraft itself! You may be warned that changing a file name extension could make the file unusable. However, ignore this because this actually indicates that you have renamed the pack.mcmeta file correctly.

On Windows, file extensions are hidden by default. If you cannot see file extensions, you will have to turn them on. The procedure to enable file extensions depends on the Windows version that you are running:

• For Windows 11, you can turn them on by opening the "View" dropdown menu in File Explorer, then hovering over the "Show" option, then turning on the "File name extensions" option.
• For Windows 8, 8.1 and 10, you can turn them on by going to the View tab in the File Explorer and checking the check box for file name extensions.
• On Windows Vista and 7, open the Windows Explorer. Then, open the Organize dropdown menu and select Folder and Search Options. A new window titled Folder Options will open. Go to the View tab, and under the Advanced settings section, find the Hide extensions for known file types option. Enable this option, and click the OK button to close the window.

On almost all MacOS versions, you can right-click the file and click "Get info" to see the extension and also make it visible.

Open pack.mcmeta in the text editor of your choice and type or copy and paste the following:

{
"pack":{
"description":"This is the description of your resource pack.",
"min_format":69,
"max_format":69
}
}

Be very careful not to forget any braces {}, commas ,, colons :, quotation marks "", or square brackets []. Missing one of these can lead to your resource pack not being recognised by Minecraft.

The text following description is required and displayed in game under the pack title in the resource pack selection screen, and must be enclosed in quotation marks "". If you wish to use special characters, you can enter the Unicode code for the character in the format \u####, where #### is the Unicode hex code for the character. Say you want to use the letter ß (eszett), which has code U+00DF. Inside the description you would type \u00DF. Make sure that you are using the correct slash, or it may not work. A list of Unicode codes can be found here.

Note: Only the characters 0000–FFFF (Basic Multilingual Plane) are supported.^{[citation needed]}

The number next to pack_format is required and tells Minecraft what release the resource pack is designed for. All valid resource pack formats with their corresponding Java Edition versions that can be used for this pack_format property are presented in the table below.

Starting with Minecraft 1.20.2, in addition to this property, a resource pack can also specify a range of pack formats it is compatible with. For more information on this topic, see the "Pack format range" section.

The supported_formats property introduced in Minecraft 1.20.2 is optional and was designed to be used to specify a range of pack formats that the resource pack is compatible with, something that was not possible with the legacy pack_format property. All valid resource pack formats with their corresponding Java Edition versions that can be used for this supported_formats property are presented in the table below.

This property can be represented in one of the following three forms:

• a single number (example: 18)
• a list that contains two numbers, where the first one denotes the start of the range and the second one the end, both inclusive (example: [18, 46])
• an object that contains two children — min_inclusive and max_inclusive — to specify the start and end of the range, similarly to the list above (example: { "min_inclusive": 18, "max_inclusive": 46 }).

Note: Even though this property somewhat replaces pack_format, the latter is still required and has to be specified in order for the resource pack to be read correctly by Minecraft. Also, if supported_formats is present, it must contain the value declared in pack_format.

If an icon is not specified, a generic cobblestone icon appears next to the resource pack in the resource pack selection screen in game. If you would like to use your own pack icon instead, you need to name it pack.png and place it inside your resource pack folder right next to the pack.mcmeta file.

The file must be in the PNG format in any resolution and with a 1:1 aspect ratio (in other words, square-shaped), but a resolution of 128×128 px is recommended, as this is what Mojang itself uses in the default built-in resource and data packs.

At this point, you can test if the pack is formatted correctly by putting it in the game! To do this you must place your resource pack folder in the Minecraft pack folder. You can access it by selecting "Options", then "Resource Packs", then "Open Pack Folder", or you can navigate to it from your file browser:

• For Windows, right click on the start button → run → type in %appdata% → .minecraft → resourcepacks
• For MacOS, go to Library → Application Support → minecraft → resourcepacks
• For Linux, go to ~/.minecraft/resourcepacks (/home/<username>/.minecraft/resourcepacks)

Once you have the folder open, you can drag your custom pack folder and drop it in.

If you have formatted the files correctly, you should see your resource pack appear in the menu.

If you don't see your pack in the list, make sure your pack.mcmeta file is correct and saved in the folder. Look for any missing braces {}, commas ,, colons :, quotation marks "", or square brackets []. Remember that for each open brace, quotation, or square bracket, you must have a closing brace, quotation, or square bracket. Also, the formatting does not allow trailing commas (commas at the end of a list or after a single element).

Now that you have your resource pack set up, you can start adding content to it. You add most files into a subfolder called assets. Simply create a new folder inside your resource pack folder named assets. This, pack.mcmeta, and pack.png should be the only files located directly in your parent resource pack folder. Any other resource files must be located somewhere in assets or they won't be read by Minecraft.

Next, inside your assets folder are your namespace folders. These help separate the files in your resource pack so that there is no confusion between which files are located where. If you plan on modifying or replacing vanilla resources, those files would go into the minecraft namespace folder. Custom additions should go in your own namespace folder, which for this tutorial is named custom. In the future, you should use a significant or unique namespace so that there isn't a possibility of other resource packs confusing which files belong where when multiple packs are loaded.

If you plan on editing multiple resources, or to help ease of access, you may want to save a copy of the vanilla resources in an accessible location in case some things rely on other files within the directory. To do this, you need to navigate to the vanilla resources file by opening the versions folder inside the .minecraft directory. You should see a list of numbered folders, which correspond to versions that you've loaded or used in the past. Open the folder corresponding to the version you want for your resource pack (in this tutorial it would be 1.21.10) and extract the JAR file located inside, which can be done by right clicking the file and selecting a file archiver from the "Open With" option. You may want to save this in an accessible location for future reference, as certain tasks such as modifying block models require textures in addition to the model files. If you do not have a program that can open .jar files simply change the extension from .jar to .zip.

This section goes through the process of modifying a texture, using the creeper texture as an example.

First, you need the vanilla resource to get the texture you want to edit. This is located in the extracted version folder that was created in the previous section. In the extracted folder, navigate to assets→minecraft→textures→entity→creeper where you can find creeper.png. Save a duplicate of this file somewhere accessible or keep the folder window open during the next few steps.

Next you'll need to replicate the folder structure of the vanilla pack within your resource pack, which lets Minecraft know to use the texture. Since we are modifying a default texture, this is in the minecraft subfolder of our assets folder. Within the minecraft folder of your resource pack, do the following:

1. Inside minecraft, create a folder called textures.
2. Inside textures, create a folder called entity.
3. Inside entity, create a folder called creeper.
4. Copy the creeper texture from the vanilla resource pack into your newly created creeper folder.

Now that you have the normal creeper texture placed in your resource pack, open it up in the image editor of your choice. It should look something like the image shown.

Since texture files are very small, you may need to zoom in.

A quick note on textures

If you've never seen a texture before, the above image might surprise you. A lot of textures look this way and are "wrapped" around a model, like wrapping paper around a present.

Now it's time to be creative! Edit the texture however you want. For simplicity, this example adds a headband. Note where the changes are and compare it to the color-coded texture above.

Once you are happy with your texture, save the file as creeper.png. It is important that it is saved with the same name as the default asset or otherwise it cannot detect and load your texture.

Now you can load up Minecraft and spawn a creeper with your custom texture! If it doesn't show up, make sure that you've selected your resource pack. If it still doesn't work, make sure you've named the file properly and placed it in the correct folder.

If you are playing with multiple resource packs loaded, there may be some textures that are in your pack that aren't being shown. This is because of the way resource packs are loaded in Minecraft. All selected resource pack files are loaded from the bottom up as they are shown in the selection menu, so if there is a resource pack that is loaded above yours, it may replace files that you've changed. This can cause various issues with using multiple themed resource packs that have differing textures, so make sure you have your resource pack at the top.

Sometimes you may want to change one of the Minecraft models. To do so you need a file archiver to get the default model and texture along with a 3D modelling tool to edit the model. Blockbench works well in this case since it can export directly to the .json format needed for models.

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 modelling editor.

Note: If you are doing a basic "Just Simple Nonanimated Textures" resource pack, the .json files are unnecessary. Otherwise, if you are doing special features to change what the texture looks like when certain parameters are true or false, then the .json files would be necessary. For example, if you created a resource pack that makes grass blocks smooth, the .json files would prevent you from having dirt lines everywhere in your world that already uses code. 

In modelling the ladder, we use Blockbench. Once you have opened the program, press Ctrl+O to open the model selection menu. After the open dialog has appeared, go to the location where you saved ladder.json and select .

You then should be facing a ladder that 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 a full-sized cube. Then, under Textures on the left panel right click ladder.png, then click Apply to Untextured Faces.
• In the top left, there is an image of the ladder, with a 1×1 highlighted region. Move this to change the texture to what you want it to be. Repeat until all sides of the block are as wanted.
• Go to "File -> Save Model" and save in resourcepacks/Tutorial_Resource_Pack/assets/minecraft/models/block/ladder.json (Replace "block" with "blocks" for 1.12 and below).

Now we have created a new model for the ladder block in Blockbench.

Go to getpaint.net and download paint.net for free.

• Open paint.net.
• Do Ctrl+O and go to .minecraft/textures/block/ladder.png and double click.
• Edit the Ladder however you want.
• When you're done, press the X button in the top right of the window. It opens a dialog if you changed anything and ask if you want to save your work. Press Save then okay twice. You don't need to change anything in the menus.

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.

Just like modifying the default textures or models, you can substitute custom sounds in place of the default ones. This example shows how to change the boss music in the ender dragon fight.

Similar to the custom texture and models, you'll first need to know the path of the sound you want to change.

1. Inside your .minecraft folder, navigate to assets/indexes, which contains a list of numbered .json files.
2. Find the .json file corresponding to your Minecraft version (e.g. 1.19.json), and open it with the text editor of your choice.
3. In this file you can find all the sounds found in Minecraft. Press  +  to search for your sound.
   • For a list of filenames for music, you can check Music#List
4. Your sound path should look something like this: minecraft/sounds/music/game/end/boss.ogg

1. Inside your resource pack folder, navigate to assets/minecraft.
2. Create a new folder named sounds.
3. Now inside your sounds folder, you need to create new folders depending on your sound's path. For example, if your path is minecraft/sounds/music/game/end/boss.ogg, you need to create the folders sounds/music/game/end.
4. In the last folder (in this example, it's end) you can put in your new sound file. Make sure you named the file to the file that you're replacing, or in this example, boss.ogg.
   • Note that this file must be a .ogg file. To convert your sound file to a .ogg file, you can use the free website Online-Convert.com

If everything went according to plan, you have now replaced a sound in Minecraft. To test it:

1. Make sure you have enabled your resource pack.
   • If you already had Minecraft open with your resource pack enabled, you can press  +  to reload all resource packs.
2. Use the /playsound command to play your sound. In our example, type: /playsound minecraft:music.dragon master @s

In addition to modifying default sounds, you can add your own! In this example, a new player hurt sound can be added without replacing any of the current player hurt sounds.

In order to add a sound, you'll need to know where it should actually go by determining its path. Unlike replacing sounds, you should go straight to your resource pack folder and search in there.

1. Find and open your version's .json index file (e.g 1.19.json) from .minecraft/assets/indexes.
2. Press  +  to search for your sound path.
   • In this case, the location for the player hurt sounds looks like this: minecraft/sounds/damage/.

1. Going to your resource pack folder, navigate to Tutorial_Resource_Pack/assets/minecraft.
2. Inside the minecraft folder, create a folder named sounds.
   • If you already have a sounds folder from replacing a default sound, open that folder.
3. Within the sounds folder, create a folder that matches the directory of the sound you want to add. In this case, we are going to create a file called damage.
4. Add your sound here.
   • The sound must be a .ogg file. Like in the previous section, you may use the free website Online-Convert.com or use Audacity as mentioned at the top of the page.
   • Also note the already existing files seen in your .json file from above. In this case, five other hurt sounds exist within the minecraft/sounds/damage/ folder, two for falling at different heights (fallbig.ogg and fallsmall.ogg) and the other three are when the player actually gets hurt (hit1.ogg, hit2.ogg, and hit3.ogg) Since we want to add a fourth sound to the existing three hurt sounds, we cannot reuse those file names. For simplicity, name your sound hit4.ogg.

Because we are adding a sound, we must change the associated sound event in sounds.json.

1. Go back to assets/minecraft in your resource pack folder.
2. Create a text file named sounds.json. Do make sure that the file extension is indeed .json and nothing else.
3. At your choice, paste the following template into sounds.json:

{
"entity.player.hurt":{
"sounds":[
{
"name":"damage/hit1"
},
{
"name":"damage/hit2"
},
{
"name":"damage/hit3"
},
{
"name":"damage/hit4"
}
],
"subtitle":"Hurt"
}
}

• The above code only applies to this example, which adds a new damage sound. If you are changing a different sound event, replace entity.player.hurt with the sound event listed in the vanilla sounds.json file.
• You can find out the id used by Minecraft for each sound folder. By using /playsound in-game, you can determine this id. In this case, using /playsound minecraft:entity.player.hurt master @s confirms that the player's hurt sound is indeed classified as entity.player.hurt.
• Make sure the name fields are in lowercase characters only. The names of your files should be in lowercase as well. Otherwise, the resource pack may fail to use your new sounds.
• The subtitle field dictates the text to display when the sound is played. It can either be a string of text, or can use a field defined in a lang file.^{[needs testing]}
• In addition to these fields displayed, you may add more additional fields to the sounds.json file to specify more parameters such as volume and pitch. A detailed list of additional sounds.json fields can be found here.
• Correct .json formatting is required! Any missing bracket, comma, etc. causes the resource pack to fail.

If there is an error anywhere in your sounds.json file, none of the sounds described in it appear in-game. If this happens, you should check the spelling and file paths.

If everything went according to plan, you have now added a sound to Minecraft. To test it:

1. Make sure you have enabled your resource pack.
   • If you already had Minecraft open with your resource pack enabled, you can press  +  to reload all resource packs.
2. Use the /playsound command once again to play your sound. In our example, type: /playsound minecraft:entity.player.hurt master @s. For this example, it likely requires multiple tries, as hurt sounds are chosen randomly.

You can add completely new languages to Minecraft using a resource pack. Assuming that your new language is <lang>^[1] and its country/region is <country>^[2], the pack.mcmeta file will look like this:

{
"pack":{
"description":"This is the description of your resource pack",
"pack_format":18,
"supported_formats":[18,46]
},
"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/lang inside your resource pack. When you launch the game, choose your resource pack, open the Language selection screen, and your new language should 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 1.7-pre, 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.

An example of an animation file is this:

{
"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. By default, it makes each frame last only one tick:

{
"animation":{}
}

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

An example of a texture property is this:

{
"texture":{
"blur":false,
"clamp":true
}
}

Character sizes in fonts are determined by the last line of pixels that contains pixels that 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 considers as part of the character.

• Launch the game
• Click on Options
• Click on Resource Packs
• Find "Tutorial_Resource_Pack" (Or the name of the pack if you named it something else) 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, edit your resource pack, go to resource packs in options, remove your pack from the active list and exit, go back, and reapply it. Alternatively, saving the texture to the resource pack and pressing  +  reloads the pack without the need to reload the default textures first.

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

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

1. Make sure your pack format is a .zip-folder.
2. Upload the pack on a file hosting website, e.g. MCPacks.
3. Copy the download link of your pack. IMPORTANT: If you are using your own server or some other host then you have to make sure that you are using a direct download link. You also need to make sure to use a SSL certificate that is compatible with the shipped Java version 8 u51. (MC-143768)
4. Open the server.properties with the text editor of your choice.
5. Search for the line resource-pack=.
6. Paste the download link after the equal sign.
7. Optional: Set the require-resource-pack property to true to force people to use the resource pack.
8. Save your changes to the server-properties and restart your server.
9. Enjoy!

Servers can have an icon that appears 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 should display next to the server name. If it does not show up properly, you may have the wrong file type. Go to Creating a pack.mcmeta file above.
