Ace's Spell Utils
Developers building Iron's Spells 'n Spellbooks addons can use Ace's Spell Utils, a NeoForge utility API with classes for spellcasting mobs, bosses, boss music and imbueable equipment.
What it does
The mod is a utility API for creators of Iron's Spells 'n Spellbooks addons. It supplies methods and classes that addon developers can call from their own code, and it does not add new spells or items for players to use directly. Iron's Spells 'n Spellbooks is required and must be installed alongside it.
Its classes cover spellcasting entities and boss encounters. A spellcasting mob class lets mobs with custom models perform timed casts of several kinds. Separate classes help build bosses and spellcasting entities with custom models, and a boss music manager handles custom and dynamic boss music. Support for imbueable curios, imbueable staffs and sheath curios is included as well.
The API is used by eight other catalog mods, including Cataclysm: Spellbooks, Hazen 'n Stuff, Discerning The Eldritch and Magic of Color. The code is open source under the MIT License, so any addon developer may use the API in their own mods. The author will keep adding features when new needs come up, and issues or suggestions go to the project's GitHub page.
