Nodewire

A Minecraft NeoForge 1.21.1 mod that replaces redstone with a node-based logic system. Build logic visually in an in-world editor, then export it as a reusable graph — across sub-level boundaries (Sable) and alongside Create + Create Aeronautics.

Features

• Visual node editor opened on a placed Nodewire block. Pan, zoom, drag nodes, draw wires.
• Unified selection model — nodes, groups, and comments share the same press / drag / marquee / Del / accent-border logic. Marquee selects all three kinds; drag on a selected item moves the whole selection (including group members and nested sub-groups) in one undoable step.
• Save & load graphs to client-side files (<gamedir>/nodewire-graphs/<name>.snbt) and reuse them between worlds.
• Node groups — collapse parts of a graph into a reusable subgraph. Groups can be nested, saved as standalone templates, renamed inline (double-LMB), and live-synced when you edit the master template.
• Comments + wire labels — annotate the editor with floating text boxes and label individual wires for legibility.
• Cross-sub-level logic — designed to function across Sable sub-level boundaries (e.g., Aeronautics aircraft). Sable Companion provides safe no-op defaults so the mod runs without Sable installed.
• Create-friendly — works alongside Create 6.0.10 + Ponder + Flywheel. Reads/writes Create wireless-redstone frequencies.
• Create Aeronautics integration — Aeronautics Input node binds to per-block state (propeller RPM, burner signal, vent pressure, …) across ~33 channels on 7 block kinds.
• Tweaked Controllers integration — Controller Input node binds gamepad axes/buttons to graph signals.
