Description

A new library/API mod for all of my Iron's Spellbooks Addons!

This mod does not do ANYTHING on it's own!!

This mod is mainly created for Iron's Spellbooks add-on developers and myself included in mind... Since I have soo many ISS addons it's annoying to copy-paste every necessary things from one place to another whenever I start working on a new addon. Thus.. this library is created!

What this Library/API mod adds for addon devs:

Many pre-made patterned particle managers
AdvancedRandomImbuingCurio class to create curios that on right-click, imbues itself with specified random spells
A way to add spells from non-spellbook curios to spell-wheel selection (use itemtag spell_imbued_curio.json)
Easy way to create flexible trades with AdvancedTrades class
Comfortable armor imbuement options with customizable slots and pre-imbued spells with AbstractImbueableArmorItem class
Geckolib Geo armor items, Geo magic sword items with GeoArmorItem & GeoMagicSwordItem classes
MultiAttributeCurio class that support multiple attributes
AdvancedSpell class for playing random animations and sounds on cast start-finish from a list, with a boolean to choose either play them on a order or not
CurioUtils class for easily checking wearing curio on a player
SummonCheckHelper class for checking summons in a radius with owner (I mainly use it for summon limit system on T.O Tweaks mod)

Any interested ISS addon dev can dm me and I'll grant a access to this project's Github repo!

I’ve also recently opened a Patreon to support the development of my mods. If you like my mods and want to support the development, it would mean a lot <3. There are perks for patrons that you can check out on the Patreon page (such as Alpha/Beta versions and Patreon specific dev-teasers).

This is not just about supporting me. If you like a mod or a modder and you can, consider supporting them. Modding takes a lot of time and effort, and every bit of support really helps the whole community and motivates the modder to keep going. So if you want and can, please do consider.

Why your project is Closed Source and How can we get access to it?

In the past, I had some unfortunate experiences with my college projects (personal matters) that left me with trust issues. Let’s just say I’ve developed a sort of trauma, and it’s hard for me to trust people easily. Since I’m fairly new to this community, I feel the need to be cautious. That’s why my projects are currently closed-source. However, if I stay in the modding scene long enough and build more trust, I might consider making them open-source in the future.

For now, if you’re a known modder or someone I personally know and you’d like access to my projects for personal use or to help me directly, feel free to reach out. You can contact me on Discord or CurseForge, and I’ll gladly provide collaboration access to my GitHub repositories.
