Creating Items

Creating your first material

To start off, open the newly created materials.json file. This file will contain all materials needed by your addon. Both items and blocks are described in this file. So let's create a simple ruby item. We can use minecraft's old unused ruby texture.

We just have to add it to our materials file:

materials.json

{
  "ruby": "item/ruby"
}

And add the texture to our asset pack at assets/textures/item/ruby.png. So our file structure looks like this:

If you want an item with a custom model, you can just link to it the same way. Just put the model file the models folder instead.

Vanilla item material

The vanilla item material (which is used to alter clientside behavior of items) will be automatically chosen based on the item behaviors (i.e. a damageable item for tools or a sword for tools that can't break blocks in creative).

If you still need to set the material type explicitly, you can do so by setting the material property:

materials.json

{
  "ruby": {
    "item": {
      "material": "diamond",
      "model": "item/ruby"
    }
  }
}

Items with multiple models

Some items have multiple models. For example, the vanilla bow item has multiple models while drawing the bow. Nova makes this process a lot easier. Instead of having to specify each model explicitly, you can specify a range and file name format. For example a diamond bow with multiple models would look like this:

materials.json

{
  "diamond_bow": {
    "item": {
      "models": {
        "item/diamond_bow/%s": [0, 3]
      }
    }
  }
}

This will generate a diamond bow with 4 models using the texturestexture/item/diamond_bow/0 - texture/item/diamond_bow/3.

If your models don't have a fixed number format, you can also list them by hand:

materials.json

{
  "diamond_bow": {
    "item": {
      "models": [
        "item/diamond_bow/not_pulled",
        "item/diamond_bow/pulled",
        "item/diamond_bow/shooting",
        "item/diamond_bow/releasing"
      ]
    }
  }
}

Applying an armor texture

To apply an armor texture to your item, simple add the armor property:

materials.json

{
  "star_chestplate": {
    "item": "item/star_chestplate",
    "armor": "star" // (1)!
  }
}

1. The name of your armor texture. See: registering an armor texture

We'll implement these items in code later. Let's create a block in the asset-pack in the next section.
