Hex Casting
by petrakat
Hex Casting lets players write spells as short programs: a stack-based system where patterns drawn on a hexagonal grid become spells cast in-world.
What it does
Spells in Hex Casting are built from patterns drawn on a hexagonal grid, and they run as stack-based programs, so a caster can chain operations without precompiling them. The mod adds its own progression through an in-game journal that reveals information over time. Items that can cast hexes can be crafted and handed to other players.
The mod requires Caelus API, Cardinal Components API, Cloth Config API, Fabric API, Fabric Language Kotlin, Inline, PAUCAL and Patchouli, so every one of those must be installed alongside it. Required by 99 other catalog mods, including Hexal, Hex Gloop, MoreIotas, HexTweaks and Hexlink, it is the base that those add-ons extend. Hex Casting runs on client and server, so the server and every player need it, and it is published for Fabric, Forge, NeoForge and Quilt across the 1.19.2 – 1.20.1 range, under the MIT License, which makes it open source.
Key features
On-the-fly casting
Hexes are cast directly from patterns drawn on the grid, without a separate compile step before use.
Craftable hex items
Items that carry a hex can be crafted and given to other players, letting spells travel with the items.
In-game journal
A journal given at spawn holds the mod's guide, and its entries reveal more as the player progresses.
Lore and progression
Ancient lore is uncovered through play, and the mod's themes of madness and the sentient life of a barren world run through its content.
