Aero Bearing

1.0.9 added

The Aero Bearing is a Create kinetic block paired with a Sable physics body. Power enters through the half-shaft on the back face (axial input, like create:mechanical_bearing), and the assembled structure becomes an independent physics body (sub-level) driven by a rotary constraint — it does not carry stress through.

Modes

The bearing has two modes:

Mode	Behaviour
Stress Driven (default)	Input RPM drives the target angle tick-by-tick (convertToAngular). The sub-level rotates continuously. Sequenced angle inputs (e.g. create:sequenced_gearshift, hand crank, valve handle with TURN_ANGLE) are honoured, so the sub-level rotates exactly the commanded angle.
Lua Control	Skipped the "RPM × time = angle" accumulation: the rotation angle is set directly via setTargetAngle(). The stress network is still consumed for stress only (impact 4.0, same as simulated:swivel_bearing). Entered with setControlMode(true) or automatically by the first setTargetAngle().

Lua API

The peripheral type is aero_bearing (wrap by direction, e.g. peripheral.wrap("right"), or peripheral.find("aero_bearing")).

Method	Description
setTargetAngle(degrees)	Absolute positioning of the sub-level (in degrees). Requires assembly; automatically enters Lua Control mode. mainThread=true
getTargetAngle()	Current target angle (degrees, server-authoritative)
getTargetAngleRad()	Current target angle (radians)
setControlMode(enabled)	Enter / leave Lua Control mode (keeps the current orientation, no jump)
isControlMode()	Whether Lua Control mode is active
isAssembled()	Whether a sub-level has been assembled
assemble()	Assemble the structure into a sub-level; returns whether it succeeded
disassemble()	Disassemble the sub-level back into world blocks; returns whether it succeeded

local b = peripheral.wrap("right")

-- Assemble the structure in front of the bearing
print(b.assemble())            -- true if a structure was assembled

-- Lua Control mode: position the sub-level at an absolute angle
b.setTargetAngle(90)           -- rotate to 90° (auto-enters Lua Control mode)
b.setTargetAngle(-45)          -- rotate back

-- Query state
print(b.getTargetAngle())      -- -45.0
print(b.isControlMode())       -- true

-- Leave Lua Control mode, back to stress-driven rotation
b.setControlMode(false)

Differences from simulated:swivel_bearing

	swivel_bearing	Aero Bearing
Power input	Cogwheel meshed from the side	Direct axial input — shaft/network connects straight to the bearing axis
Stress network	Through-shaft (stress passes through)	Not through — the sub-level is driven by a physics constraint, stress stops at the bearing
Angle control	Via network speed (sequenced inputs)	Stress mode: same; Lua Control mode: angle set directly via Lua, skipping the network angle accumulation
