Introduction

RarityCore is a Minecraft mod that introduces a seven-tier rarity system to the game. It provides features such as modifying item name colors, inserting tooltip information, and changing the background of item slots for specified rarity levels.
Additionally, it comes with preset configurations and powerful configuration management tools. For players, this is a ready-to-use rarity system; for developers, it serves as a convenient rarity management tool.

Core Features

🎨 Visual Customization

• Dynamic visual effects: Automatically adjust colors and styles based on item rarity;

• Mod integration: Integrates with some mods' rarity systems and is compatible with other mods' GUIs.

📝 Flexible Configuration

• Multi-level configuration support: Includes four configuration methods—data packs, commands, configuration files, and code registration;
• NBT matching configuration support: Supports matching items' NBT data to achieve more complex rarity configurations;
• Visual editing: Provides a visual editing mode where rarity modifications can be completed with simple mouse clicks;
• Comprehensive documentation system: Offers bilingual (Chinese and English) documentation covering everything from basic usage to advanced customization;

Integration Notes

Apotheosis

This mod treats Apotheosis's six rarities as its own rarities, overriding all other rarity configurations, including but not limited to weapon qualities and gem qualities. This feature can be toggled in the configuration file.

Rendering Compatibility

This mod actively supports the Refined Storage and Sophisticated Core mods, enabling items in Refined Storage's terminal interface and related mod interfaces like Sophisticated Backpacks to render rarity backgrounds.

Compatibility Issues

ImmediatelyFast

When installed alongside ImmediatelyFast, this mod causes the high-transparency portions of item background textures rendered in the hotbar to disappear. This makes the item background textures in the hotbar appear as only three-quarters of their original size when using default textures. However, item background rendering within the GUI remains unaffected.

The author indicates they will attempt to fix this in future versions, though there is currently no good solution available.

EMI

When installed alongside EMI, EMI's "batch processing" feature causes many items in EMI tabs to not render item backgrounds. Disabling the "batch processing" feature will restore normal functionality.
