Hostile Neural Networks Legacy

**Turn mob knowledge into an automated supply of resources.**

Hostile Neural Networks Legacy brings HNN's data-model progression to Minecraft 1.12.2. Bind a model to a supported creature, train it through combat, and use Forge Energy and Prediction Matrices to simulate predictions. Feed those predictions into a Loot Fabricator to produce the drops you need.

#### Build your simulation network

- **Deep Learner and Data Models:** collect and train models, track their progress, and improve prediction accuracy.
- **Simulation Chambers and Loot Fabricators:** automate predictions and choose a fixed output or a rotating loot queue.
- **Data Center:** build a **7 × 7 × 7** multiblock that processes up to **25 models** in parallel, with shared inventories and configurable IO ports.
- **Extra HNN included:** fuse four targets into a Perfect Model, train with the Model Simulator and upgrade cards, and scale production with **V1–V4 Ultimate Simulation Chambers and Loot Fabricators**. No separate Extra HNN installation is needed.
- **Optional mod integrations:** additional models for Draconic Evolution, Thermal Foundation, Tinkers' Construct, and Blood Magic. With Blood Magic installed, the **Digital Well of Suffering** uses a trained data model and FE to supply LP to a linked Blood Altar.
- **Modpack customization:** JSON model and tier definitions, configuration options, and English and Simplified Chinese interfaces.

The base installation includes **29 vanilla mob models**, with **8 optional mineral models** available through configuration. Supported mod integrations add their models when the corresponding mods are installed.

#### Getting started

Bind a Model Framework to a creature, place the model in a Deep Learner, and defeat matching mobs to train it. Move a Basic-tier or better model into a Simulation Chamber, supply FE and Prediction Matrices, then send the resulting predictions to a Loot Fabricator. Expand into a Data Center and Perfect Models as your resource needs grow.

#### Requirements and optional features

**Minecraft 1.12.2 · Cleanroom 0.4.0 release, without an `-alpha` suffix · Java 25**

Install this mod on both the client and server. **Placebo is not required.** Optional **JEI 4** pages explain recipes and machine outputs; optional **Ponder Legacy** scenes demonstrate the workflows. Ponder also requires **CraftTweaker 4.1.20.698**. All optional mods are installed separately.

The current production build has passed client and dedicated-server checks on the stated Cleanroom baseline, with and without the documented optional integrations. Model and save conversion from other HNN or Deep Mob Learning implementations is not provided.
