About this project

What does StackBoost add?

🚀 StackBoost

StackBoost is a server modding project designed to provide greater control, performance, and flexibility over item behavior within the server.

Its primary purpose is to allow advanced configuration of item stack limits, offering both global defaults and fine-grained overrides, while maintaining high performance and full compatibility with the server ecosystem.

✨ Key Features

  • 📦 Configurable default stack size applied globally

  • 🎯 Per-item configuration (Items) that overrides the default value

  • 🧩 Pattern-based configuration (Patterns) using regular expressions for bulk overrides

  • 🔁 Clear priority system:

    • Items and Patterns always override the DefaultValue

    • The DefaultValue is applied only to items without a specific configuration

  • ⚙️ Direct integration with the server API

  • 🚀 High performance, with no negative impact on gameplay

  • 🔧 Simple and intuitive configuration

  • 🧩 Compatible with other mods and plugins

🎯 Configuration Behavior

StackBoost applies stack size values following a well-defined priority order:

  1. Items — exact item ID matches
  2. Patterns — regex-based matches
  3. DefaultValue — applied only when no specific rule exists

This ensures precise control while keeping configuration files clean and maintainable.
