Datapacks

Datapacks are a built-in Minecraft feature that allows you to customize game mechanics by adding or modifying content without altering the core game or mods. In the context of MT Inventory Weight, datapacks can be used to configure the number of pockets for armor items.

Why Use Datapacks with MT Inventory Weight?

Using datapacks with MT Inventory Weight allows you to:

• Define pockets for armor: Assign the number of pockets to different armor items based on your gameplay preferences.
• Extend the mod: Include custom or modded armor items and specify their pockets.
• Customize gameplay: Adjust how pockets affect item carrying capacity to better fit your world.

How Datapacks Work for Armor Pockets

The mod looks for .json files within the inventoryweight folder of a datapack. These files define the number of pockets for armor items. When the world or server loads, the mod reads these .json files and applies the specified configurations to the armor items in the game.

Steps to Create a Datapack for Armor Pockets

Here’s how you can create a datapack to define armor pockets for MT Inventory Weight.

Create the Datapack Folder Structure

1. Navigate to the datapacks folder inside your Minecraft world or server directory.
   • Example path: world/datapacks/
2. Inside the datapacks folder, create a new folder for your datapack, e.g., [datapack_namespace].
3. Inside this folder, create another folder called data.
4. Inside data, create a folder called inventoryweight (this name is important as the mod looks for this folder).
5. Inside inventoryweight, create a .json file to hold your armor pockets definitions. For example, name it armor_pockets.json.

The folder structure should look like this:

datapacks/
└── [datapack_namespace]/
    └── data/
        └── inventoryweight/
            └── items.json

Make sure to follow this structure so that the MT Inventory Weight mod can properly detect and load your custom configurations.

Configuring items.json

Inside items.json, you will define custom pockets vlaues using the following format:

{
  "items": [
    {
      "item": "minecraft:leather_helmet",
      "pockets": 5
    },
    {
      "item": "techreborn:quantum_leggins",
      "pockets": 2
    }
  ]
}

• "item": The full item ID (including the namespace, e.g., minecraft: or a mod's namespace).
• "pockets": The number of pockets to apply to the armor item.

Activating the Datapack

Once the folder structure and items.json file are properly set up, the datapack will be automatically loaded when your Minecraft world or server starts. If you make changes to the datapack, use the /reload command in Minecraft to apply them.
