Features

I found a way - using the intelligence from a settled villager mind, with some special "concepts" from wild creatures - to create a kind of special spell-casters: Reactive Focus.

  • Reactive Focus: focus bound with certain game events happening on player
    • Events to listen to:
      • enemy targeting player (without tag #hexautomata:ignore_targeting)
      • player taking damage (both source and attacker without tag #hexautomata:ignore_hurt)
      • player shooting projectile
      • projectile hit something
      • melee attack something
      • killing something
      • being teleported
    • Crafted by brainsweep recipes
      • all from Akashic Record as source block
    • Places to take effect:
      • Inventory (default: false)
      • Main/Off hand (default: true; takes no effect if Inventory set to true)
      • Ender Chest (default: false)
      • Curios/Trinkets slots (default: true)
      • config entries controlling whether sources above are enabled
  • Reactive Focus Nexus: an item holding multiple Reactive Focuses
    • all inner focuses take effect as if they're outside
    • crafted with a multiblock structure, ending with another brainsweep (accepting targets with tag #hexautomata:multi_threaded)
      ritual multiblock
  • Special patterns taking effect exclusively inside triggered events

I am mind, and mind is media... Body is the vessel, heavy and fragile... I shall expose my mind, taking me out of the vessel, I shall see more, I ...

  • Another advancement-based progression and functions extending Brainsweep great spell :3
    • a new way of transportation

HAPatches and PatchAction

Allowing packmakers to patch actions the same way as OpBrainsweep.
Also exposes two special errors: USE_ORIGINAL and STOP_ALL for better control over custom brainsweeps.

BrainsweepCallback

Exposes BrainsweepCallback to server/startup scripts binding, allowing custom brainsweep callbacks to be registered.

Registering a callback:

BrainsweepCallback.create(priority,
    entityId, iotaTypeId, // nullable type ids
    (entity, iota, env) => {
        // return SpellAction.Result or null
        return BrainsweepCallback.buildResult(env => {
            // do something
            // or stop here
            throw PatchAction.STOP_ALL
        }, 0)
    }
);
  • entityId and iotaTypeId accept ResourceLocation strings. Iota type IDs under the minecraft namespace are automatically remapped to hexcasting.
  • Use BrainsweepCallback.forceSet(key, callback) to override an existing callback registration.

HexParse

Registers Reactive Focus as an item I/O handler via HexParseAPI.CreateItemIOMethod, enabling HexParse to read and write iotas directly from/to Reactive Focus items.

Frequently Asked Questions

HexAutomata server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is HexAutomata compatible with fabric and forge and neoforge?

HexAutomata officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HexAutomata – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HexAutomata consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
