Public API

FunctionDescription
moveFeet(input)Provides manual override control for the support legs.

Hooks

HookDescription
init(jbeamData)Connects to the hydraulic cylinder device and sets initial state.
updateGFX(dt)Manages the state machine for feet movement. Automatically moves legs to the 'attached' or 'detached' heights based on coupling status.
onCouplerAttached(nodeId, obj2id, obj2nodeId)Triggers automatic retraction if the trailer is connected to a tractor.
onCouplerDetached(nodeId, obj2id, obj2nodeId, breakForce)Triggers automatic extension when the trailer is uncoupled.

Hydraulics Combustion Engine Control

Controls engine RPM and throttle to maintain hydraulic pump pressure on vehicles where the hydraulic system is driven by the combustion engine (e.g., excavators, loaders). Manages idle-up and load-sensing.

Orbitrol (Orbital) Steering

Controls hydraulic orbital steering units used on heavy equipment and industrial vehicles. Converts steering input into hydraulic flow to steering cylinders, providing full hydraulic steering without a mechanical linkage.
