Create Aeronautics Addon: Plough & Roll!

The addon connects Create's Mechanical Plough and Mechanical Roller to the Create Aeronautics and Sable setup. A mechanical plough acts on the spots a simulated contraption projects into the main world, while a mechanical roller lays paving over that cleared ground and follows the contraption's present facing, upside-down contraptions included. Simulated contraptions gain a Simulated Behavior roller mode, an opt-in setting that runs the projected roller behavior with paving blocks taken from the same contraption's inventory. The option labelled Replace Tracks keeps the normal Create behavior.

With Create Aeronautics and Sable installed, a standard Create roller still runs the native Clear Blocks Pave routine. The addon restores the native roller ticker for ordinary main-world contraptions, so an existing roadbed is replaced as well as empty spaces being filled. Create Aeronautics and Sable interrupt the usual break-then-pave flow when a roller meets existing roadbed, and the addon restores it. The mod also adds new ponders for Sable simulated contraptions. Create, Create Aeronautics and Sable are all required, and the mod is published for NeoForge 1.21.1 only, under the MIT License as open source code.
