Signal

by Space Walker

Signal is a Fabric library that provides an API for mods adding redstone-like blocks and signal systems.

FabricClient and serverMIT LicenseOpen source1.19 – 1.19.4

What it does

Signal gives other mods a shared base for building new redstone-like systems. Its central idea is that redstone power is handled as an abstraction, so different signal types can interact without each mod writing its own rules. Mods built on it can add entirely new redstone-like systems and remain compatible with one another. Fabric API is required. Signal runs on client and server, so both the server and every player need it, and it is published for 1.19 – 1.19.4 under the MIT License as open source.

Key features

  1. Redstone-like block API

    Developers can register new blocks that behave like redstone components, using the library's own signal types.

  2. Abstracted redstone power

    Redstone power is modeled as a general concept, so the handling of interactions between signal types is not repeated in each mod.

  3. Cross-mod compatibility

    Systems built on the API stay compatible with other mods that use it, which makes it easier to add entirely new signal systems.

How it compares

Full comparison

Redderstone is an Apache License 2.0 open source mod for Fabric, Forge and Quilt, published for 1.19.2, and it is a finished redstone addition rather than a shared API. RedstoneClock is MIT License open source for Fabric only, covering 1.21.4 – 26.3, so it targets a later range than Signal. Weather Detector, under MIT License and open source, supports Fabric, Forge and NeoForge for 1.18.2 – 1.21.1 and works as a weather-sensing block.

What the author says

Signal is an API for adding redstone-like blocks. It abstracts the concept of 'redstone power' and handles interactions between different signal types. This makes it easier for different mods to add entirely new redstone-like systems while remaining compatible with each other. Check out the documentation on GitHub…
