Minecraft

A couple of published Minecraft mods, both on Modrinth and CurseForge, both open source.

Schematician's Goggles

Create: Aeronautics extends the very popular Create mod with airships and physically-simulated contraptions - vehicles whose flight depends on mass distribution, thrust, and where the center of mass sits. Aeronautics already ships an "Aviator's Goggles" item that shows some of this physics data while you're wearing them.

Schematician's Goggles is an upgrade tier on top of that. Instead of flat HUD overlays, the physics data gets rendered directly into the 3D world. The whole world starts looking like a live Contraption Diagram - the same shader Aeronautics uses for its in-game blueprints gets applied to active vehicles, with force arrows and centers of mass drawn where they actually are in space. It uses Aeronautics' existing visual language on purpose, so it reads like a feature that was always supposed to be there rather than a third-party graft.

No Mending

Vanilla Minecraft's Mending enchantment repairs your gear from XP orbs. It's strong, it's easy to get in bulk, and once you've farmed a few villagers it basically removes the durability system from the game. No Mending rebalances the loop around armor and tools:

1. Mending is removed by default - you can optionally keep it as a rare exploration reward via config
2. Repairs cost 0 XP and bring an item back to full per craft, so topping off gear isn't a chore
3. The Unbreaking enchantment applies the same durability multiplier to armor that it already does to tools, so the two are finally on equal footing
4. At 1 durability, armor automatically unequips and tools refuse to be used - so durability is a real signal again instead of a number you ignore until your gear shatters
5. Repair recipes are data-driven, so modpack authors can add or override them without writing any Java
