Member Data Documentation

dampingRateFullThrottle

PxReal physx::vehicle2::PxVehicleEngineParams::dampingRateFullThrottle

Damping rate of engine when full throttle is applied.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchEngaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchEngaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchDisengaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchDisengaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Range: [0, inf)
Unit: torque * time = mass * (length^2) / time

dampingRateZeroThrottleClutchDisengaged

PxReal physx::vehicle2::PxVehicleEngineParams::dampingRateZeroThrottleClutchDisengaged

Damping rate of engine when no throttle is applied and with disengaged clutch.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchEngaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchEngaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchDisengaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchDisengaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Range: [0, inf)
Unit: torque * time = mass * (length^2) / time

dampingRateZeroThrottleClutchEngaged

PxReal physx::vehicle2::PxVehicleEngineParams::dampingRateZeroThrottleClutchEngaged

Damping rate of engine when no throttle is applied and with engaged clutch.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchEngaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchEngaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchDisengaged and dampingRateFullThrottle: dampingRateZeroThrottleClutchDisengaged + (dampingRateFullThrottle-dampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Range: [0, inf)
Unit: torque * time = mass * (length^2) / time

idleOmega

PxReal physx::vehicle2::PxVehicleEngineParams::idleOmega

Minimum rotation speed of the engine.

Range: [0, inf)
Unit: radians / time

maxOmega

PxReal physx::vehicle2::PxVehicleEngineParams::maxOmega

Maximum rotation speed of the engine.

Range: [0, inf)
Unit: radians / time

moi

PxReal physx::vehicle2::PxVehicleEngineParams::moi

Moment of inertia of the engine around the axis of rotation.

Range: (0, inf)
Unit: mass * (length^2)

peakTorque

PxReal physx::vehicle2::PxVehicleEngineParams::peakTorque

Maximum torque available to apply to the engine when the accelerator pedal is at maximum.

Note

The torque available is the value of the accelerator pedal (in range [0, 1]) multiplied by the normalized torque as computed from torqueCurve multiplied by peakTorque.

Range: [0, inf)
Unit: mass * (length^2) / (time^2)

torqueCurve

PxVehicleFixedSizeLookupTable<PxReal, eMAX_NB_ENGINE_TORQUE_CURVE_ENTRIES> physx::vehicle2::PxVehicleEngineParams::torqueCurve

Graph of normalized torque (torque/peakTorque) against normalized engine speed ( engineRotationSpeed / maxOmega ).

Note

The normalized engine speed is the x-axis of the graph, while the normalized torque is the y-axis of the graph.
