Fully interactable subworlds not bound to coordinate axes. Now with Mixins support!

Description

Imagine an airship soaring through your world, its sails gilded by sunset... A floating island where every block obeys your will... A realm where gravity is a guideline, not a law.


What is it?

  • MetaWorlds - Mixins revives the legendary MetaWorlds mod with a modern Mixins rewrite, enabling the creation of Subworlds — fully interactive, movable, and rotatable structures that exist independently of the main world’s coordinates.

    Build the impossible:

  • Flying ships, airships, or mobile battlefortresses
  • Rotating puzzle rooms
  • Interactive structures (doors, buttons, chests work seamlessly).

    No more static builds! Your creations can now move, tilt, and defy physics



Key Features

  • Mixins-based – No more ASM conflicts with modern 1.7.10 mods.
  • Enhanced collision – Entities interact smoothly with moving and rotating subworlds.
  • Dynamic sounds – Position-aware audio effects.
  • Shader support (Angelica required) - Subworlds can both cast shadows and get casted upon.
  • Built as an api – Want to base your mod off it? You're welcome!


Requirements

  • That's a Mixins mod, built using UniMixins. Therefore it requires them.

 

Incompatibilities

  • Optifine. This mod rewrites too much code to be compatible with it.
  • Fastcraft. For same reasons. (But you can use Angelica instead)
  • More yet to be found. If you find any - leave it in the comments

Important Notes

  • This is a beta! Report bugs in the comments.
  • Designed as a library for advanced users – expect rough edges.
  • Blocks for subworld creation are not intended to be used in survival, and are still kind of buggy. You can still get them from creative menu though.

Backstory

  • The original MetaWorlds (by MMM_MasterM) was a 1.7.2 marvel, but its ASM code became outdated. TCLProject’s 1.7.10 port kept it alive, and now this Mixins port unlocks its full potential for modern 1.7.10 setups.
