Quick answer
Which HexAutomata release should I use?

Where it goes
Is HexAutomata required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does HexAutomata-fabric-1.20.1-0.3.5.1.jar need?
HexAutomata-fabric-1.20.1-0.3.5.1.jar. Change the file and its required mods may change too.
Install Hex Casting, Cloth Config API (Fabric/Forge/NeoForge), Inline, Cardinal Components API and 11 more first, but 3 required mods have no matching file for this setup. Do not mix loader builds to force a match. 14 come through another mod in the chain.
14 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

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
- enemy targeting player (without tag
- Crafted by brainsweep recipes
- all from
Akashic Recordas source block
- all from
- Places to take effect:
- Inventory (default: false)
- Main/Off hand (default: true; takes no effect if
Inventoryset to true) - Ender Chest (default: false)
- Curios/Trinkets slots (default: true)
- config entries controlling whether sources above are enabled
- Events to listen to:
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)
- 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
Interop
KubeJS
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)
}
);
entityIdandiotaTypeIdacceptResourceLocationstrings. Iota type IDs under theminecraftnamespace are automatically remapped tohexcasting.- 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.
