Getting started [ ]
Data packs can be used to add or modify functions, loot tables, globe structures, advancements, recipes, tags, dimensions, predicates and globe generation.
What not to practise [ ]
At that place are some things that you should not exercise while creating a data pack. Hither is a list of "don'ts":
- Release Minecraft versions or modifications that allow players to play without having bought Minecraft from Mojang.
- Release the decompiled source code of Minecraft in any way.
Creating a data pack [ ]
To create a data pack, start off by navigating to the datapacks binder within the earth binder.
To find the earth folder, locate the saves folder within your game directory, which is .minecraft by default.
- In singleplayer, you tin select your world, click on "Edit", and so "Open earth folder".
- On a server, you can navigate to its root directory (where server.backdrop is located), and so enter the
globedirectory.
Once yous are in the datapacks binder, create a folder with a name of your choice. It will be your data pack'due south proper name. Enter the data pack folder.
The showtime affair to do after y'all are in the binder is to create a pack.mcmeta file. This lets Minecraft identify your data pack.
Creating an MCMETA file [ ]
To create an MCMETA file, right click inside your data pack folder and create a new text document. Name this file "pack.mcmeta".
- Annotation
Make sure the file extension is .mcmeta and non .txt when you rename information technology! In other words, remove your sometime file extension. Y'all may exist warned that changing a file name extension could brand the file unusable. All the same, this really indicates that y'all have renamed the pack.mcmeta file correctly.
If you are using Microsoft Windows and tin't see file extensions, for Windows 10, you can plow them on past going to the View menu of the file explorer and checking the bank check box for file name extensions. For Windows below Windows 10, you tin can uncheck "hide extensions" in folder settings.
Text editor [ ]
Any text editor should work. It is recommended that the chosen text editor supports JSON, which is the format used by files of mcmeta extension and near other files in a data pack. Notation that virtually text editors practice non recognize mcmeta extension as JSON. Thus, you need to configure the editors manually.
pack.mcmeta content [ ]
Open up pack.mcmeta in your text editor and paste or type the post-obit:
{ "pack" : { "pack_format" : ix , "description" : "Tutorial Information Pack" } } - Annotation
This file is written in JSON! This tutorial does not go into specifics nigh 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. Make sure to non write trailing commas. Missing ane of these can lead to your information pack not working correctly! To check your files y'all can use a JSON validator, such every bit the one found on JSONLint.
"pack_format" [ ]
The value of "pack_format" tells Minecraft what release the data pack is designed for, and is different for certain versions. The post-obit listing shows what versions each value is associated with:
-
4for versions 1.13 – 1.14.4 -
5for versions 1.15 – 1.16.1 -
6for versions 1.sixteen.2 – one.16.5 -
sevenfor versions one.17 - ane.17.one -
viiifor versions one.eighteen - ane.eighteen.1 -
9for versions i.18.ii -
10for versions i.19+
Note: As more updates are released, values may be changed or added.
"clarification" [ ]
The text following "clarification" can be whatever cord or a raw JSON text. It will show up when y'all hover over your data pack in the output from /datapack list and in the data pack UI when creating a globe. In pack.mcmeta, information technology is possible to use the § symbol (run into Minecraft Formatting codes) in the clarification of pack.mcmeta and the data pack name.
Testing your pack [ ]
In one case you have created your pack.mcmeta, try testing information technology out in-game! Open the world or, if you are already in the earth, type /reload, so blazon /datapack list. It should list 2 entries. One should be [vanilla] (built-in), the 2nd one should exist named like [file/(your information pack'due south proper noun) (earth)], where your data pack's folder name goes at (your information pack'south proper name). When you hover over your data pack's entry, y'all should encounter the description of your data pack every bit you have written in description of your pack.mcmeta.
When your pack shows up, you are prepare to move on.
Troubleshooting [ ]
If yous don't encounter your pack in the list, make sure your pack.mcmeta file is correct and saved. Look for any missing curly brackets {}, commas ,, colons :, quotation marks "", or square brackets []. Recall that for each open brace, quotation, or foursquare bracket, you must take a closing bracket, quotation, or square brackets. If you still don't see your pack, make certain it's in the correct binder.
Naming [ ]
Make a binder called data in your data pack folder, where you take placed the pack.mcmeta file in. In this data folder you lot have to create i or more folders which will act as your namespaces.
Entries in data packs have resource locations in a fashion of namespace:path. The corresponding file would exist located at data/namespace/(data_type)/path.(suffix). Note that / characters in the path volition be translated into directory separators.
A few examples:
- an particular tag of ID
dummy:foo_proof/barwould be located atinformation/dummy/tags/item/foo_proof/bar.json - a office of ID
foo:handler/bar_callwould be located atdata/foo/functions/handler/bar_call.mcfunction
Legal characters [ ]
Namespaces, paths and other folder and file names in the data pack should only comprise the following symbols:
-
0123456789Numbers -
abcdefghijklmnopqrstuvwxyzLowercase letters -
_Underscore -
-Hyphen/minus -
/Forward Slash/Directory separator (Can't be used in namespace) -
.Period
The preferred naming convention is lower_case_with_underscores, called lower snake instance.
Namespace [ ]
Most objects in the game apply namespaced resource locations to prevent potential content conflicts or unintentional overrides.
For instance, if two data packs add together two new minigame mechanisms to Minecraft and both take a function named start. Without namespaces, these 2 functions would clash and the minigames would be broken. But if they have dissimilar namespaces of minigame_one and minigame_two, the functions would become minigame_one:start and minigame_two:start, which no longer conflict.
Most of the time when Minecraft requires an ID, such as for /part, you should provide the namespace in addition to the path. If you don't specify the namespace, it volition fallback to minecraft.
Make sure to always use your own namespace for anything new that yous add, and only use other namespaces if you're explicitly overriding something else, or, in the case of tags, appending to something else.
For instance, Minecraft uses the minecraft namespace, which means that this namespace should merely exist used when the data pack needs to overwrite existing Minecraft data or to add its entries to vanilla tags.
Functions [ ]
Functions are a set of commands that can be run in order.
To add functions, first create a binder named functions inside the namespace binder. Then, create a file named (function_name).mcfunction in this binder or in any of its subfolders. This volition be your function file. Your part will be named in the game equally (namespace):(name) or (namespace):(subfolder1)/(subfolder2)/.../(proper noun) when the office file is located in a subfolder.
Boodle tables [ ]
Boodle tables will tell Minecraft what should exist dropped when a mob dies or what should be generated inside containers, like chests, when opened for the first time, they tin also exist called by the /loot command.
To add loot tables, get-go create a folder named loot_tables inside the namespace folder. Then, create a file named (loot_table_name).json in this folder or in any of its subfolders. This will be your boodle table file. Your loot table volition be named in the game as (namespace):(proper name) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder. All the vanilla loot tables are in the minecraft namespace.
Here is an example of a cow'south boodle tabular array, it can exist used as a reference:
i { 2 "type" : "minecraft:entity" , three "pools" : [ 4 { 5 "rolls" : 1 , 6 "entries" : [ 7 { 8 "type" : "minecraft:item" , nine "functions" : [ 10 { 11 "function" : "minecraft:set_count" , 12 "count" : { 13 "min" : 0 , 14 "max" : two , 15 "blazon" : "minecraft:uniform" sixteen } 17 }, 18 { xix "role" : "minecraft:looting_enchant" , 20 "count" : { 21 "min" : 0 , 22 "max" : one 23 } 24 } 25 ], 26 "name" : "minecraft:leather" 27 } 28 ] 29 }, 30 { 31 "rolls" : one , 32 "entries" : [ 33 { 34 "type" : "minecraft:item" , 35 "functions" : [ 36 { 37 "role" : "minecraft:set_count" , 38 "count" : { 39 "min" : 1 , forty "max" : three , 41 "blazon" : "minecraft:uniform" 42 } 43 }, 44 { 45 "part" : "minecraft:furnace_smelt" , 46 "weather condition" : [ 47 { 48 "condition" : "minecraft:entity_properties" , 49 "predicate" : { 50 "flags" : { 51 "is_on_fire" : true 52 } 53 }, 54 "entity" : "this" 55 } 56 ] 57 }, 58 { 59 "function" : "minecraft:looting_enchant" , sixty "count" : { 61 "min" : 0 , 62 "max" : 1 63 } 64 } 65 ], 66 "name" : "minecraft:beef" 67 } 68 ] 69 } lxx ] 71 } To acquire what each tag means, see Loot tables. There is also a list of vanilla loot tables on that page.
Structures [ ]
Structures can be used with structure blocks and jigsaw blocks and/or tin overwrite how certain vanilla structures expect in Minecraft. It is saved in an NBT format. You can create an NBT file by using a construction block or by exporting a build using a 3rd party program like MCEdit.
To add structures to a data pack, first create a binder named structures inside the namespace folder. Then, put your structure file in this folder or in whatever of its subfolders. Your structure will be named in the game as (namespace):(proper noun) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder.
World generation [ ]
Custom earth generation allows data packs to change how the world generates. This is particularly useful in conjunction with custom worlds.
To modify earth generation, first create a folder named worldgen inside the namespace binder. Then, put your noise_settings file in this folder or in any of its subfolders. Your changes volition be named in the game equally (namespace):(proper name) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder.
Advancements [ ]
Advancements can exist completed by players and give various rewards.
To add together advancements, outset create a folder named advancements inside the namespace folder. Then, create a file named (advancement_name).json (You lot can't put spaces in the file name. Use lowercase messages in the file name). in this binder or in any of its subfolders. This will be your advancement file. Your advocacy will be named in the game as (namespace):(name) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder.
Recipes [ ]
Recipes are used to let players craft items.
To add recipes, get-go create a folder named recipes inside the namespace folder. Then, create a file named (recipe_name).json in this folder or in whatsoever of its subfolders. This volition be your recipe file. Your recipe will be named in the game as (namespace):(name) or (namespace):(subfolder1)/(subfolder2)/.../(proper noun) if the file is located in a subfolder.
Shaped crafting [ ]
The starting time common type of crafting is shaped crafting.
{ "type" : "minecraft:crafting_shaped" , "pattern" : [ "123" , "231" , "312" ], "key" : { "one" : { "item" : "Resource location of the item" }, "2" : { "item" : "Resource location of the item" }, "three" : { "particular" : "Resources location of the item" } }, "result" : { "particular" : "Resource location of the item" , "count" : "Numbers of items produced" } } This is a crude example of a shaped crafting recipe, every bit specified by the crafting_shaped type. pattern is a list used to specify the shape of the crafting recipe. It contains a maximum of 3 strings, each cord continuing for one row in the crafting filigree. These strings then comprise a maximum of iii single characters next to each other, each character continuing for ane spot in the crafting grid. You don't need all 3 strings, nor do you demand to take iii characters in each string. But each string should incorporate the same corporeality of characters. Y'all can use spaces to indicate empty spots.
key is a chemical compound used to specify what detail should be used for which grapheme in blueprint. This can either be specified using particular followed by an item ID or tag followed by an item data pack tag.
The effect compound speaks for itself, it specified what the resulting item should exist. count is used to specify how many of the item should be given.
This is the original recipe for a piston (can exist used every bit a reference):
{ "blazon" : "crafting_shaped" , "design" : [ "TTT" , "#10#" , "#R#" ], "cardinal" : { "R" : { "detail" : "minecraft:redstone" }, "#" : { "item" : "minecraft:cobblestone" }, "T" : { "tag" : "minecraft:planks" }, "Ten" : { "particular" : "minecraft:iron_ingot" } }, "consequence" : { "item" : "minecraft:piston" } } Shapeless crafting [ ]
At that place'south another mutual blazon of recipes, a shapeless recipe.
{ "type" : "crafting_shapeless" , "ingredients" : [ { "item" : "<item ID>" }, { "item" : "<item ID>" }, [ { "item" : "<detail ID>" }, { "item" : "<detail ID>" } ] ], "result" : { "detail" : "<item ID>" , "count" : 5 } } As specified past the crafting_shapeless type, this is a recipe without a pattern. The ingredients tin can be put in the crafting filigree in any shape or class. In the case, at that place's a list inside the ingredients compound. This means whatsoever of the items in this listing tin exist used.
This is the original recipe for Burn Charge (can be used as a reference):
{ "type" : "crafting_shapeless" , "ingredients" : [ { "item" : "minecraft:gunpowder" }, { "item" : "minecraft:blaze_powder" }, [ { "detail" : "minecraft:coal" }, { "detail" : "minecraft:charcoal" } ] ], "event" : { "item" : "minecraft:fire_charge" , "count" : three } } It is also possible to create new smelting recipes.
{ "blazon" : "smelting" , "ingredient" : { "item" : "<item ID>" }, "result" : "<item ID>" , "experience" : 0.35 , "cookingtime" : 200 } This is a rough example of a smelting recipe. "ingredient" is used to specify the item y'all are going to smelt. "result" is going to specify the result. In "experience", you are able to choose the amount of xp gained for smelting, and in "cookingtime" the corporeality of fourth dimension that it will take for the item to smelt, which in this case is 10 seconds (200 ticks = ten seconds).
This is the default smelting recipe for a diamond ore:
{ "type" : "smelting" , "ingredient" : { "item" : "minecraft:diamond_ore" }, "outcome" : "minecraft:diamond" , "experience" : 1 , "cookingtime" : 200 } Tags [ ]
Main article: tag
Tags are used to group blocks, items, entities, or functions together. Additionally, the minecraft:tick part tag is used to run functions every tick and the minecraft:load function tag is used to run functions every time the globe is (re)loaded.
To add tags, offset create a folder named tags inside the namespace folder. Inside this folder, create folders named blocks, items and functions. Then, create a file named (tag_name).json in one of these folders or in any of their subfolders. This will be your tag file. Your tag will be named in the game equally (namespace):(name) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder.
Predicates [ ]
Predicates are technical JSON files that represent the conditions for boodle tables, /execute if predicate command, or predicate target selector statement.
To add predicates, showtime create a folder named predicates inside the namespace binder. Then, create a file named (predicate_name).json (Yous can't put spaces in the file proper name. Employ lowercase messages in the file proper noun). in this binder or in any of its subfolders. This will exist your predicate file. Your predicate will exist named in the game as (namespace):(proper name) or (namespace):(subfolder1)/(subfolder2)/.../(name) if the file is located in a subfolder.
Dimensions [ ]
Dimensions are JSON file used to specify all the dimensions a earth contains.
To add dimensions, first create a folder named dimension inside the namespace folder. Then, create a file named (dimension_name).json (You tin't put spaces in the file name. Use lowercase letters in the file name). in this folder. This will exist your dimension file.
Custom dimensions can be accessed in game using /execute in (namespace):(dimension_name)
