Curios API Mod

Curios API is an equipment API and Slot System for Minecraft, allowing for more usage for items and tools rather than just the traditional armour and shield/offhand slots. On the player Inventory Screen, in the top left of the player model, there is a Curios Icon (which looks like a mechanical circle with an X going through it, it starts grey but turns yellow when hovered on) where you can access the different slots for the different types of items. Mods can easily add their own Curios slots for their custom items.

The mod by itself does not come with any new content or slots, only 2 example items for developers to reference when making their mods that are only accessible in creative mode. The player will be able to do something with Curios once they install mods which use it. Some mods which use Curios are MCDoom and Nameless Trinkets, and there are also some commonly used slots.

Curios are good for being a central equipment slot registry to which developers can easily add stuff, others may exist, but Curios is trying to centralise it. The slots have lots of customisation, such as backgrounds, appearance, and size, and can also be added or removed at any time for any reason. The slots can also use the vanilla tag system to accept more than just some hard-coded items. The items are also compatible with inventory mechanics such as enchantments, mending, curses and other mechanics developers may add. All this is easily accessible from the simple GUI in the player inventory, which is often a strip with all the slots attached in a straight line with check marks next to the slots, but that can easily be customised. Slots can also be modified or added/removed, and the whole mod can be disabled with commands. The mod provides an extensive amount of commands.

Even though Curios is very easy to use, the author still has documentation for players, which mainly contains information about the config and other stuff that would be common for modpacks. There is also documentation for developers and information about how to add it to a project.

Curios are for both Forge and Fabric.
