Stacc API Mod is an API-only mod that allows developers to create items with stack sizes much greater than 64. It also replaces the item count renderer for very large numbers (greater than 1000) to avoid the text from covering up adjacent slots. Additionally, it implements various bug fixes to support greater stack sizes.
Features:
- Allows items to stack in quantities much larger than the default 64.
- Adjusts the item count display for very large numbers.
- Introduces a semi-safe serialization scheme for large stacks, ensuring the world won’t be lost if the mod is uninstalled (though many items will be).
Requires:
Fabric Loader
Fabric API
