About this project
What does RarityCore add?
Introduction
The Rarity Core is an all-encompassing rarity enhancement mod that establishes a new rarity system, aiming to make rarity no longer a privilege for certain items and to enhance the presence of rarity in all aspects.
Imagine when you open your inventory. Each item comes with a unique color background, with gray for ordinary items, purple for epic gear, and gold for rare treasures - you can instantly distinguish what's valuable!
Feature
This is what 'rarity' truly means
Instead of the boring three-tier system with changing names, the mod presets seven levels of rarity, which will render a unique colored background behind the item and add a prompt in the notification box, making each item of different rarity look distinct.


True - Out-of-the-Box, Rarity is No Longer a Privilege
This mod not only presets rarity information for over 70 mods, but also features an "automatic rarity calculation" function that evaluates the rarity of items based on their crafting recipes.
With a set of combined techniques, without additional configuration, the rarity information can cover over 70% of items in most scenarios!
As a player, you can enjoy the rarity system once the mod is installed! As a creator, you can save a lot of time spent on basic tasks!

High Visual Customization
Don't like the name color changing? You can turn it off!
Want to modify the tooltips for a specific level? Feel free to do so!
Don't want a monotonous gradient background? Prefer to use a background you've drawn yourself? Of course!
Baby-Level Configuration Process
With just a few clicks of the mouse, you can adjust the rarity level. It couldn't be simpler!

Meeting Advanced Requirements
If you want to configure rarity for items like TacZ firearms that rely on Tag differentiation, you can use this mod's NBT tag matching system (upgraded to item data component matching system after version 1.21.1), which allows for more complex rarity configuration by matching NBT tags or data components, enabling differentiation between items with the same ID but different NBT tags.

Technical Advantages
The quadruple configuration methods of data packets, commands, configuration files, and code registration cater to the configuration needs of different groups.
Modern caching and network synchronization ensure a smooth gaming experience.
Mod Interaction and Compatibility
SearchCarefully
SearchCarefully provides a looting system similar to that in Escape from Tarkov. It assigns looting time to items based on the rarity values from the Rarity Core.

ColorTooltips
ColorTooltips offers vibrant and smooth tooltip displays, deeply customized for the Rarity Core. It is highly recommended to install alongside the Rarity Core.

Apotheosis and its dependencies
This mod treats the six rarity levels of Mythical as its own rarity levels, overriding all other rarity configurations, including but not limited to weapon quality and gem quality. This feature can be toggled on or off in the configuration file.
The mod also interacts with the Apotheotic Additions mod, and the three additional rarities will also be considered as part of this mod's rarity system.
Rendering Compatibility
This mod actively integrates with the Refined Storage and Elegant Core mods, enabling items within the Refined Storage terminal interface and the interfaces of affiliated mods such as Elegant Backpack to be rendered with rarity backgrounds.
Known Compatibility Issues
ImmediatelyFast
When this mod is installed alongside ImmediatelyFast, it can cause the high-transparency parts of the item background textures rendered in the hotbar to disappear. This results in the game appearing as if the item background textures on the hotbar are only 3/4 of their original size when using default textures. It's as if they've been nibbled on. However, the rendering of item backgrounds within the GUI remains unaffected.
Disabling the ImmediatelyFast HUD batching feature will restore normal functionality.
EMI
When this mod is installed alongside EMI, the "Batch Processing" feature of EMI will cause a large number of items in the EMI tab to not render their item backgrounds.
Disabling the "batch processing" feature of EMI will restore normal functionality.
Other Issues
For other resolved compatibility issues, please refer to the Rarity Core Wiki.

Frequently Asked Questions
Q1: Will it support Fabric?
A1: I have done this before, but I gave up and won't try it again in the future.
Q2: When installed alongside the xxx mod, the rarity background is incorrectly rendered over the item texture.
A2: This is usually caused by the mod using the same method as the rarity core to render elements on items. I am currently looking for a solution.
Q3: Why is the durability bar sometimes partially obscured by the rarity background?
A3: I am currently seeking a solution.
Q4: Will it support the latest Minecraft version?
A4: At least for now, I intend to support the Rarity Core and related sub-modules from version 1.20.1 to the latest version of Minecraft (only mainstream versions, such as 1.21.1, 1.21.11, 26.x, excluding 1.20.6)
Q5: Why do you not plan to support 1.20.6?
A5: Everyone has their own troubles.
