PMWeather Aeronautics

PMWeather Aeronautics connects ProtoManly’s Weather with Sable / Create Aeronautics physics contraptions.

It allows Sable physics objects and Create Aeronautics contraptions to react to PMWeather wind, storms, and tornadoes using exposed surface pressure instead of a simple fake push. Wind is sampled from PMWeather, converted into physics wind, applied across exterior faces, and then passed into Sable so the normal physics engine handles movement, rotation, collision, mass, and inertia.

Features

• PMWeather wind affects Sable / Create Aeronautics physics objects.
• Quadratic surface-pressure wind model.
• Larger exposed faces naturally catch more wind.
• Stronger storm and tornado winds scale much more realistically than light wind.
• Exterior surface patch sampling for sealed builds, walls, roofs, large ships, irregular shapes, and exposed undersides.
• Uneven pressure can create natural yaw, roll, and tumbling instead of only pushing from the center.
• Local airflow lift support for lift providers.
• Tornado updraft support using bottom-facing exterior surfaces.
• Configurable wind strength, tornado lift, sampling limits, and debug options.
• Debug commands for checking wind and sample usage.
• Compatible with Sable/Create Aeronautics simulated contraption diagrams.

Version 0.8.0 Highlights

Version 0.8.0 reworks the main body wind system. Older versions used a less realistic wind push behavior that made light 10–15 mph winds too strong while tornado winds did not feel strong enough by comparison.

The new system uses quadratic surface pressure, meaning wind force scales more like real wind pressure:

wind force ∝ wind speed² × exposed surface area

This makes normal wind less overpowering while still allowing storms and tornadoes to move contraptions much more naturally.

Version 0.8.0 also fixes a Create Aeronautics / Sable diagram crash caused by PMWeather Aeronautics wind forces. Thanks to @michardy for the detailed report in issue #2.

Requirements

• Minecraft 1.21.1
• NeoForge
• ProtoManly’s Weather / PMWeather
• Sable

Commands

All commands are under:

/pmaero

Check PMWeather wind at your current position:

/pmaero wind

Check current wind sample usage:

/pmaero samples

Enable live sample monitoring:

/pmaero samples live on

Disable live sample monitoring:

/pmaero samples live off

Start detailed wind debugging:

/pmaero winddebug start

Stop detailed wind debugging:

/pmaero winddebug stop

Check whether detailed wind debugging is running:

/pmaero winddebug status

Config Notes

The default 0.8.0 body wind influence is:

[body_wind]
windInfluence = 0.06

This value is tuned for the new quadratic surface-pressure system. Raising it makes all body wind stronger, including normal wind and tornado wind. Lowering it makes contraptions less affected by wind overall.

Tornado lift can be adjusted separately:

[tornado_updraft]
tornadoUpdraftStrength = 0.35
tornadoUpdraftPressureStrength = 1.0

If updating from older versions, the mod will back up older generated configs once and regenerate a fresh config with the new 0.8.0 defaults.

Notes

PMWeather Aeronautics does not directly fake contraption movement or force objects along preset tornado paths. It calculates wind pressure, lift, and torque from PMWeather wind and exposed contraption surfaces, then lets Sable handle the final physics result.
