SFM-Flow

Flowcharts are built on a canvas where each node is a step in a routine. Nodes stay in a compact standard size so the workspace stays readable, and gradient colors help group active routines. Right-clicking a node opens a menu to rename it, edit its settings, change its color, copy it or delete it. The central computer runs the flowchart logic, reads the cables it touches, and turns them into executable commands.

The mod adds network cables in standard and hardened variants, with hardened cables resistant to blasts for hazardous places. Observer cables detect block updates next to them without emitting redstone, and redstone emitters and receivers handle independent analog signals at levels 0 through 15. Item and fluid hatches use a 3x3x3 vacuum area to suck up ground items and fluids. Logic evaluations run off the main thread in dedicated daemon pools, so the game tick loop is not slowed down.

SFM-Flow is built for NeoForge 1.21.1 only and is published under the MIT License as open source. Every player and the server need a copy of the mod. It is an alpha release: the author advises keeping normal backups and warns that API changes are still likely.
