Introduction

In Minecraft, the slash data command is a powerful tool for interacting with NBT (Named Binary Tag) data. Whether you want to copy inventories, speed up furnaces, or even make pigs fly, the slash data command has got you covered. But before we dive into the command itself, let's first understand what NBT data is and how it works.

What is NBT Data?

NBT data, or Named Binary Tag data, is a format used in Minecraft to store various types of data such as numbers, text, boolean values, lists, arrays, and compound structures. It allows for efficient storage and retrieval of information within the game. Each piece of data is accompanied by a tag, which gives it a specific name and makes it easy to access and manipulate.

NBT Data Types

Before we can fully grasp the power of the slash data command, let's take a closer look at the different types of NBT data.

Numbers

Numbers in NBT data can be integers or floats. They represent numerical values such as health points, coordinates, or any other numeric property of an entity or object in the game.

Text

Text data in NBT consists of strings of characters. It allows for storing and manipulating textual information such as item names, chat messages, or entity names.

Boolean

Boolean values in NBT can be either true or false. They are used to represent binary states, such as whether an entity is invulnerable or whether a block is powered.

Lists

Lists in NBT are collections of values, all of the same type. They are useful for storing multiple values of the same kind, such as a list of enchantments on an item or a list of potion effects on a player.

Arrays

Arrays in NBT are similar to lists, but they are rarely used in practice. Arrays can store values of different types, making them less convenient to work with compared to lists.

Compound

A compound in NBT is a container that can hold multiple tags. It is used for grouping and organizing related data under a single tag. Compounds can contain other compounds, creating a hierarchical structure for complex data storage.

Slash Data Command - Merge Subcommand

Now that we have a basic understanding of NBT data, let's explore the slash data command in more detail. The first subcommand we'll look at is "merge", which allows us to merge additional data into an entity.

Example: Merge Data into an Entity

To illustrate how the merge subcommand works, let's consider an example where we want to make a pig fly. We can achieve this by adding a "motion" tag to the pig's NBT data. The motion tag specifies the velocity of the entity in three dimensions: X, Y, and Z.

To merge data into an entity, we first need to select the target entity. In this case, we'll choose the nearest pig. We can do this by specifying the entity type as "pig" and using the sorting option "nearest" with a limit of one. Once we have our target entity, we can add the desired NBT data.

To make the pig fly, we set the motion tag to zero on the X axis, one on the Y axis, and zero on the Z axis. This will make the pig move upwards in the game world.

But wait! We don't want the pig to start flying randomly. To prevent this, we can set the pig's invulnerable tag to one, making it immune to damage from players or other entities.

With the slash data command, we can perform these operations with ease and create interesting interactions within the game. For example, you can use a command block minecart to create a pig archery range, where shooting arrows at the pigs will trigger various effects.

The merge subcommand is straightforward and convenient for adding specific tags to entities, allowing for unique gameplay experiences.

Slash Data Command - Modify Subcommand

The merge subcommand is great for adding new tags to entities, but what if we want to modify existing tags? That's where the "modify" subcommand comes in handy.

Example: Modifying an Entity's Health

Let's take a look at an example of modifying an entity's health using the slash data command. Imagine we have a pig with a specific health value, and we want to change it programmatically.

To modify an entity, we first need to select the target entity, just like we did with the merge subcommand. Then, instead of adding new tags, we specify the target path, which is the name of the tag we want to modify.

In this case, let's modify the pig's health tag. To do this, we write "health" as the target path. Since the health tag is a float value, we can only set the number to something specific. Any attempt to perform other operations will result in an error.

We can choose to set the health tag to a specific value, such as one, which would give the pig half a heart. Setting it to zero would result in the pig's death. The modify subcommand allows us to manipulate specific tags with precision.

But what if we want to set the pig's health based on another tag's value? That's where the real power of the slash data command shines.

Modifying Health from Another Tag

With the modify subcommand, we can modify a tag based on the value of another tag. Let's say we want to set the pig's health equal to our hunger bar's value.

We can achieve this by using the "from" option followed by the "entity" parameter to access another entity's NBT data. In this case, we'll use ourselves as the source entity by specifying the "at" parameter as "s".

Now we need to specify the path we want to check in ourselves. Let's choose the food level tag, which represents our current hunger level.

By running this command, we will dynamically set the nearest pig's health to match our hunger level. If we starve ourselves, the pig will die. This illustrates the potential for complex interactions and gameplay mechanics that the slash data command enables.

The modify subcommand provides granular control over specific tags, allowing for intricate manipulations within the game world.

Slash Data Command - Sub Commands for Lists and Arrays

So far, we have explored the merge and modify subcommands, which work with individual tags. But what if we want to work with lists or arrays of values? That's where the slash data command offers additional subcommands: "append", "prepend", and "insert".

These subcommands allow us to modify existing lists or arrays by adding new values or inserting them at specific positions.

Append

The append subcommand adds a new value to the end of a list or array. It is useful when we want to extend the list without worrying about the current order of elements.

Prepend

The prepend subcommand adds a new value to the beginning of a list or array. It is useful when we want to prioritize a newly added value over existing ones.

Insert

The insert subcommand allows us to insert a new value at a specific index within a list or array. It is helpful when we want to maintain a specific order or insert a value at a precise position.

These subcommands provide flexibility when working with complex data structures and enable us to create dynamic and interactive game elements.

Slash Data Command - Merge Subcommand

The merge subcommand, as mentioned earlier, works similarly to the modify subcommand, but with a slightly different purpose.

Example: Merging Data with a Compound Tag

In some cases, we may not want to modify the entire NBT structure of an entity, but rather merge additional data with a specific compound tag. The merge subcommand allows us to achieve this.

Let's imagine a scenario where we want to change an item's ID and count without affecting its other properties like custom names or enchantments.

By using the merge subcommand, we can selectively change specific tags within a compound, ensuring that the existing data remains intact while adding new values.

While writing this article, I struggled to come up with a widely applicable use case for this particular subcommand. However, in specific situations where you need to modify certain tags within a compound, the merge subcommand provides a convenient solution.

Slash Data Command - Remove Subcommand

The remove subcommand is another useful tool offered by the slash data command. As the name suggests, it allows us to delete a specific tag entirely from an entity or object.

The syntax for the remove subcommand is similar to the other subcommands. Simply specify the name of the tag you want to remove, and the slash data command will take care of the deletion.

The remove subcommand enables us to clean up unnecessary or obsolete tags within our NBT data, improving efficiency and ensuring a cleaner overall structure.

Slash Data Command - Get Subcommand and NBT Paths

The get subcommand of the slash data command is deceptively simple, but it has significant utility in testing and data retrieval.

Using Data Get to Test Commands and Access NBT Data

The data get subcommand retrieves and displays the value of a tag in the chat. Although it may seem trivial, it serves a crucial role in command testing and debugging.

By using data get, we can verify if our commands are working as intended and check the values of specific tags within our NBT data. It helps ensure accuracy and identifies any issues that may arise.

Accessing Specific Tags with NBT Paths

To access specific tags within an NBT structure using the data get subcommand, we need to understand NBT paths. NBT paths allow us to navigate through the hierarchy of tags and access the desired value.

For example, if we want to retrieve the number of items we are holding, we can use the data get command with the path "SelectedItem.Count".

NBT paths are not limited to just one level. If we want to access more nested tags, we can use dots to specify the desired path, e.g., "SelectedItem.Tag.Enchantments" to retrieve the enchantments on the selected item.

To access a specific enchantment from the list, we can use an array-like notation with square brackets and an index. For instance, "SelectedItem.Tag.Enchantments[0]" will get us the first enchantment in the list.

The data get subcommand, when used in conjunction with NBT paths, provides a powerful means of accessing and extracting specific data from complex NBT structures.

Conclusion
