Sloth's Cursed Blocks

by SlothyUwU

Sloth's Cursed Blocks is a data pack that adds slightly cursed but functional blocks, such as a crafting table made from logs and an upside-down grass block.

What it does

The data pack adds custom blocks built on existing vanilla content. Some are based on blocks that exist in the game, some on proposed or scrapped vanilla content, and some on rubies. A crafting table log is crafted from two oak logs and yields two crafting tables, a stone furnace is crafted from eight stone arranged like a standard furnace, and a deepslate furnace uses eight deepslate. The upside-down grass block is made from one grass block, and the stripped oak chest looks like a stripped oak log. A ruby block is crafted from nine rubies.

The blocks are meant to cause confusion and amusement when players show them to friends. Furnaces, crafting tables and other functional blocks still work like their regular, non-cursed counterparts. The pack is a resource and data addition rather than a set of code changes, and the server must run it while players may add it on their side. Files are published for Fabric, Forge, NeoForge and Quilt across 13 release versions, 1.21.4 – 26.3, with snapshot builds also published. The mod is released under All rights reserved and is not open source.
