About this project
What does Arc - Core add?
Arc – Core
Arc – Core is the foundational library for the Arc project, providing a collection of utilities, abstractions, and shared systems designed to simplify development with the Hytale API.
This module is not intended to be used as a standalone gameplay mod. Instead, it acts as a core dependency for other Arc-based modules and projects, handling common functionality so developers can focus on building features rather than reinventing systems.
✨ Features
- Utility classes and helper functions for working with the Hytale API
- Shared data structures and common logic used across Arc modules
- Simplified interaction layers for faster and cleaner development
- Modular and extensible design for easy integration
