PMweather Aeronautics compat

PMWeather Aeronautics

PMWeather 0.17.x+ users: Set both values in PMWeather's compat.sable section to 0 in the pmweather-server.toml so its built-in Sable wind forces do not stack with PMWeather Aeronautics.

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

Supports Sable: Ragdolls!

It makes contraptions react to PMWeather wind, storms, and tornadoes using exposed surface pressure and local airflow instead of a simple center push.

Recommended Config

[body_wind]
windInfluence = 0.06

Controls how strongly wind pushes on the exposed body of the contraption.

For survival gameplay, 0.02 is recommended if the default feels too strong.

[airflow]
airflowInfluence = 1.0

Controls how strongly PMWeather wind affects aerodynamic parts such as rudders, wings, and propellers.

Lower values reduce the effect of weather wind on those parts.

maxWindSamplesPerTick = 128

Controls the maximum number of PMWeather wind samples shared between all active contraptions each tick.

Higher values can give large or complex contraptions more detailed sampling, but may use more CPU.

Features

• PMWeather wind affects Sable and Create Aeronautics contraptions.
• Larger exposed surfaces naturally catch more wind.
• Uneven wind pressure can create yaw, pitch, roll, and tumbling.
• Rudders, wings, propellers, and other aerodynamic parts receive local airflow.
• Uses PMWeather's native 3D tornado wind, including vertical wind.
• Balloon envelopes are affected through the exterior body-pressure system.
• Adaptive sampling reduces unnecessary wind calculations.
• Multiple contraptions share the same global sample budget.

Wind Physics

Body wind uses a quadratic pressure model:

wind force ∝ wind speed² × exposed surface area

This makes strong storms and tornadoes scale much more naturally compared with light wind.

Wind is applied across different parts of the contraption, allowing off-center pressure to create rotation instead of only pushing from the middle.

Sampling

Body and airflow wind update every 2 ticks by default, or about 10 times per second at 20 TPS.

Nearby aerodynamic parts can share wind samples while still running their own normal Sable/Aeronautics physics.

Requirements

• Minecraft 1.21.1
• NeoForge
• ProtoManly's Weather / PMWeather
• Sable
• Create Aeronautics for Aeronautics contraptions

Commands

/pmaero wind

Shows the currently detected PMWeather wind.

/pmaero samples
/pmaero samples live on
/pmaero samples live off

Shows or monitors current wind sample usage.

/pmaero winddebug start
/pmaero winddebug stop
/pmaero winddebug status

Controls detailed wind debugging.

Notes

PMWeather Aeronautics does not directly move contraptions along preset paths.

PMWeather supplies the wind, PMWeather Aeronautics converts it into body pressure and aerodynamic airflow, and Sable handles the final movement, rotation, mass, inertia, and collisions.
