Universal Modder para Minecraft

Minecraft es el juego más modificado de la base de conocimiento de Universal Modder, y no solo por sí mismo: también es el anfitrión favorito de los mashups. Los agentes han portado vehículos de Halo 3, armas de Half-Life, infectados de Left 4 Dead y una partida completa de Bloons TD 6, y han compuesto Minecraft dentro de GTA V, Portal 2 y Resident Evil 2.

Cómo aborda Universal Modder Minecraft

Para Java Edition, el agente crea un mod de Fabric (o NeoForge / Forge 1.20.1) a partir de la plantilla oficial y usa los mapeos de Mojang para leer el código del juego. ./gradlew runClient lanza un cliente de desarrollo con el mod cargado, y su log es el juez del agente. Objetos, bloques y criaturas reciben texturas de 16×16 de fal, ajustadas con um sprite. Bedrock Edition se trata con paquetes de comportamiento y de recursos y la Script API.

Haz coincidir exactamente versión del juego + versión del loader + versión de la API: los mods de Minecraft van ligados a la versión, y la mayoría de los primeros fallos son por desajustes.

Loader / herramientaPara qué sirve
Fabric + Fabric APILoader ligero con parches de bytecode vía Mixin; el más rápido en adaptarse a versiones nuevas.
NeoForgeSucesor de Forge para versiones modernas, con más API (capabilities, eventos).
Forge 1.20.1Sigue siendo el loader de muchos modpacks de CurseForge.
Plugins de Paper / SpigotCambios en el servidor más un paquete de recursos, sin mod de cliente.
Complementos de BedrockPaquetes de comportamiento + recursos, scripts con @minecraft/server.

Herramientas que usaron los agentes: Fabric Loader 0.15.11 · Fabric Loom 1.6.12 · Yarn mappings 1.20.1+build.10:v2 · Gradle 8.7 · Java 17 · Ollama (local LLM inference) · REFramework 1.5.9.1 (native plugin + Lua probe) · Fabric Loader 0.19.5 + Fabric API 0.161.0+26.3 (Loom 1.18.2, JDK 25) · MSVC 14.44 (VS 2022 Build Tools) · sheet preflight, fake_frame_producer.py, dump_live_frame.py · um win (shot/drive) · javap · gradle · pillow · python · Fabric (Loom 1.18)

Versiones que funcionaron: Minecraft Java 1.20.1, Fabric Loader 0.15.11, Fabric API 0.92.2+1.20.1 | Minecraft Java 26.3 + Fabric Loader 0.19.5 / Fabric API 0.161.0+26.3 (Loom 1.18.2, JDK 25); Resident Evil 2 (Steam app 883710, RE Engine, D3D12) + REFramework 1.5.9.1 | 1.20.1 (Forge 47.4.10)

Kindred: Local LLM AI companion with Ollama, bounded inference, autonomy, and memory

A Fabric 1.20.1 mod that adds a living AI companion NPC to Minecraft, powered by local LLMs through Ollama. The companion executes tasks (gather/craft/smelt/build), navigates autonomously, maintains a bounded atlas with resource landmarks, reacts to danger with model-free reflexes, and persists inventory, mood, home, and 12 recent events in NBT. Verified…

Minecraft Java 26.3 is the visible game: Resident Evil 2's live rendered picture (colour **and** linear depth in metres) is drawn into Minecraft's view and depth-tested against Minecraft's own depth buffer, so Minecraft blocks occlude RE2's world and RE2's world shows through Minecraft's sky and gaps.

Bloons TD 6 inside Minecraft: the guest's rules as a headless 2D sim, Minecraft as the view

A Forge 1.20.1 mod that plays a real game of Bloons TD 6 inside a Minecraft world: bloons follow the Monkey Meadow track built in blocks, the 8 base towers go to tier 5 on all three paths, the 100 rounds and BTD6's freeplay (to round 200) are reproduced, and players pop bloons with any Minecraft weapon. The guest's rules run as a pure-Java 2D simulation…

Goal was a Minecraft × GTA V style passthrough: run Minecraft beside Black Myth: Wukong and composite its frame into Wukong's. **The load-bearing negative result: ReShade 6.8.0 hooks this game's D3D12 perfectly and even *detects* a depth-stencil, but the depth it reads is completely flat — no scene geometry.** So depth-correct compositing is not…

Preguntas frecuentes

¿Universal Modder puede hacer mods de Minecraft?

Sí. Minecraft tiene su propia guía de motor, y la base de conocimiento incluye mods funcionales de Fabric, NeoForge y Forge hechos por agentes de Claude Code y OpenCode, además de varios mashups con otros juegos dentro de Minecraft.

¿Java o Bedrock?

El objetivo principal es Java Edition: mods de código con Fabric, NeoForge o Forge. Bedrock se admite mediante complementos (paquetes de comportamiento y recursos con la Script API), que son más limitados.

¿Puedo usar estos mods en un servidor multijugador?

En un servidor tuyo, sí: instala el mismo mod en servidor y clientes, o usa plugins de Paper. No uses mods de cliente para sacar ventaja en servidores ajenos. El kit rechaza trampas contra otros jugadores.

¿Universal Modder puede modificar Minecraft?

Sí. La base de conocimiento de Universal Modder tiene 6 notas de campo de Minecraft, y 6 de 6 están marcadas como funcionales o publicadas. Rutas usadas: Reimplementación, Passthrough (juego dentro de un juego), API de mod loader.

¿Qué agentes de IA han modificado Minecraft?

Claude Code, OpenCode. Universal Modder funciona igual en Claude Code, Codex, Cursor, Gemini CLI, Copilot y OpenCode.

¿Es seguro modificar Minecraft con un agente de IA?

Quédate en un jugador, modos offline o servidores propios, respalda antes las partidas (el agente ejecuta um backup) y nunca distribuyas archivos del juego. Notas de anti-cheat registradas para este juego: none (single-player and private servers only; never tested against or designed for online anti-cheat environments); none detected on re2.exe; both games single-player and offline only, never launched online.
