Zarch

A strictly-typed, lightweight hierarchical state machine (HSM) library for Roblox.

Overview

Zarch is a minimal implementation for managing complex state-driven architectures within Roblox projects, with a massive focus on complete Luau type-safety and a clean API.

Note: This library is a direct, heavily-inspired rewrite of the fantastic Arch library by bohraz. Zarch is a rewrite of Arch with a focus on strict typing and a more minimal API.

Why Zarch?

• Strictly Typed: The primary benefit to using Zarch over arch is the strict typing.
• Hierarchical State Management: Zarch enables the creation of a structured system where states can be organized hierarchically, offering a clear and intuitive way to represent complex game behaviors.
• Parallel State Management: Zarch allows for the management of multiple states simultaneously, enabling the creation of complex game mechanics that require concurrent state handling.
• Lightweight & Zero-Dependency: minimal API with no bloat.

Installation

Wally

Add the following to your wally.toml:

[dependencies]

Alternatively, install via pesde:

pesde install zarchify/zarch

Quick Start Example

I reccomend you refer to the Arch documentation for a more in depth look at how to use state machines.
