Itematic 0.9.0 Preview 3 for 26.3

20th of October 2026

This preview is all about data components, as it adds context number providers for them and moves a bunch of item behaviour to data components! On top of that, the mod is now also available on CurseForge! Right on time for the mod's first anniversary...

Changes

Item Behaviour Components

• Removed minecraft:cooldown.
  • Its value has been moved to the cooldown field in minecraft:useable.
  • Note that the duration is now specified in seconds rather than ticks, matching vanilla, so you will have to divide your number by 20 accordingly.

So if you had this:

{
  "minecraft:cooldown": {
    "ticks": 20
  }
}

You now have to use this instead:

{
  "minecraft:useable": {
    "cooldown": {
      "seconds": 1.0
    }
  }
}

minecraft:block

• Moved all of its behaviour to the new minecraft:block_placer data component.
• Now provides the minecraft:block_placer data component.

minecraft:bucket

• Moved all of its behaviour to the new minecraft:bucket data component.
• Now provides the minecraft:bucket data component.

minecraft:consumable

• Made it so the minecraft:consumable data component this behaviour component provides determines the behaviour rather than the behaviour component itself, matching vanilla again.
• However, the has_consume_particles and sound fields have been moved to the has_use_particles and sound fields in minecraft:useable respectively.
• Their defaults have also changed, where has_use_particles now defaults to false and sound is entirely optional instead of defaulting to "minecraft:entity.generic.eat".
• Added the amount field.
  • Its value is a positive integer and defaults to 1.
  • Is the amount of items that get consumed when finishing using an item.
• The minecraft:consumable data component received the same changes.

So if you had this:

{
  "minecraft:consumable": {
    "has_consume_particles": false,
    "sound": "minecraft:item.honey_bottle.drink"
  },
  "minecraft:useable": {
    "animation": "drink",
    "remainder": {
      "id": "minecraft:glass_bottle"
    },
    "ticks": 40
  }
}

You now have to use this instead:

{
  "minecraft:consumable": {},
  "minecraft:useable": {
    "animation": "drink",
    "remainder": {
      "id": "minecraft:glass_bottle"
    },
    "sound": "minecraft:item.honey_bottle.drink",
    "ticks": 40
  }
}

minecraft:enchantable

• Made it so the minecraft:enchantable data component this behaviour component provides determines the behaviour rather than the behaviour component itself, matching vanilla again.

minecraft:entity

• Moved all of its behaviour to the new minecraft:entity_placer data component.
• Now provides the minecraft:entity_placer data component.

minecraft:equipment

• Made it so the minecraft:equippable data component this behaviour component provides determines the behaviour rather than the behaviour component itself, matching vanilla again.

minecraft:projectile

• Moved all of its behaviour to the new minecraft:projectile data component.
• Now provides the minecraft:projectile data component.

minecraft:tool

• Made it so the minecraft:tool data component this behaviour component provides determines the behaviour rather than the behaviour component itself, matching vanilla again.

minecraft:useable

• Made it so all data components this behaviour component provides determine the behaviour rather than the behaviour component itself, matching vanilla.
• The ticks field now always has a value and defaults to {"type": "minecraft:instant"}
  • This means that the minecraft:use_duration data component is now always added and also handles instantaneous uses.
• Added an optional has_use_particles field.
  • Defaults to false.
  • Whether to display particles when using the item.
  • When set to true, provides the minecraft:has_use_particles data component.
• Added an optional sound field.
  • The sound to play when using the item.
  • Provides the minecraft:use_sound data component.
• Added an optional cooldown field.
  • The cooldown to apply when finishing using the item.
  • Provides the minecraft:use_cooldown data component.
• Now provides the minecraft:use_passes data component from the passes field.

Example:

{
  "minecraft:useable": {
    "animation": "eat",
    "has_use_particles": true,
    "sound": "minecraft:entity.generic.eat",
    "ticks": 32
  }
}

minecraft:weapon

• Made it so all data components this behaviour component provides determine the behaviour rather than the behaviour component itself, matching vanilla.
