MetaWorlds – Mixins

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• The original MetaWorlds (by MMM_MasterM) was a 1.7.2 marvel, but its ASM code became outdated.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.
