Illegal Items

by FROSTYTRIX

Illegal Items brings Bedrock Edition's unobtainable blocks, items and entities into Java Edition, including three portal blocks, real fluids and tipped arrows.

FabricClient and serverMIT LicenseOpen source1.21.5

What it does

The mod compiles a set of illegal block items, entities and oddities that Bedrock Edition players have had over the years but Java Edition never offered in survival. Command-only blocks and held items that never left the debug menu now exist as obtainable content, along with a handful of smaller oddities.

Among the additions are the Nether Portal, End Portal and End Gateway blocks, each available as a vanilla item form that places a real vanilla block. Still water and still lava are real fluids that never spread, and they swim, drown, burn and set fire to their surroundings like the vanilla versions do. Dyeing a dog's collar applies the colour to the animal itself, and a dyed coat stays with the wolf.

The mod runs on the client and on the server, so both need it. It is published for Fabric only, on 1.21.5, with 1.1.0 as the latest file. The code is open source under the MIT License, and Minecraft 1.21.5 is the only game version covered.

Key features

  1. Unobtainable block items

    Command-only blocks and debug-menu items become placeable and craftable content in survival worlds.

  2. Portal blocks as items

    Nether Portal, End Portal and End Gateway each exist as an item that places the real block, with the portal facing the placement direction.

  3. Still fluids and bucket tags

    Still water and still lava hold their place, and the fluids carry the minecraft:water and minecraft:lava tags that other mods check for when filling a bucket.

  4. Tipped arrows and redstone levels

    Tipped arrows carry their potion effect and fly like plain arrows, while redstone dust accepts power levels from 0 through 15.

  5. Infinity and dyeable dogs

    Consumables enchanted with Infinity never run out, and a dog can be dyed so the colour is saved with the wolf.
