Detailed Description

Properties of a PhysX vehicle engine.

If the engine setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleDriveStandardAPI applied. If the intent is to share the engine setup, PhysxVehicleEngineAPI can be applied to a separate prim which can be linked to (see PhysxVehicleDriveStandardAPI).

Constructor & Destructor Documentation

PhysxSchemaPhysxVehicleEngineAPI ( const UsdPrim &  prim = UsdPrim() )

inlineexplicit

Construct a PhysxSchemaPhysxVehicleEngineAPI on UsdPrim prim .

Equivalent to PhysxSchemaPhysxVehicleEngineAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 72 of file physxVehicleEngineAPI.h.

PhysxSchemaPhysxVehicleEngineAPI ( const UsdSchemaBase &  schemaObj )

inlineexplicit

Construct a PhysxSchemaPhysxVehicleEngineAPI on the prim held by schemaObj .

Should be preferred over PhysxSchemaPhysxVehicleEngineAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

UsdSchemaType

static PHYSXSCHEMA_API PhysxSchemaPhysxVehicleEngineAPI Apply ( const UsdPrim &  prim )

static

Applies this single-apply API schema to the given prim.

This information is stored by adding "PhysxVehicleEngineAPI" to the token-valued, listOp metadata apiSchemas on the prim.

Returns

A valid PhysxSchemaPhysxVehicleEngineAPI object is returned upon success. An invalid (or empty) PhysxSchemaPhysxVehicleEngineAPI object is returned upon failure. See UsdPrim::ApplyAPI() for conditions resulting in failure.

static PHYSXSCHEMA_API PhysxSchemaPhysxVehicleEngineAPI Get ( const UsdStagePtr &  stage, const SdfPath &  path  )

static

Return a PhysxSchemaPhysxVehicleEngineAPI holding the prim adhering to this schema at path on stage.

If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

*  PhysxSchemaPhysxVehicleEngineAPI(stage->GetPrimAtPath(path));
*  

PHYSXSCHEMA_API UsdAttribute GetDampingRateFullThrottleAttr

(

)

const

Damping rate of engine when full throttle is applied (units: torque * seconds = mass * distance * distance / seconds).

The value has to be greater or equal 0.

Note: if the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchEngaged (see corresponding attribute) and dampingRateFullThrottle: dampingRateZeroThrottleClutchEngaged + ((dampingRateFullThrottle-dampingRateZeroThrottleClutchEngaged) * acceleratorPedal).

Note: if the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between dampingRateZeroThrottleClutchDisengaged (see corresponding attribute) and dampingRateFullThrottle: dampingRateZeroThrottleClutchDisengaged + ((dampingRateFullThrottle-dampingRateZeroThrottleClutchDisengaged) * acceleratorPedal).

Note: the default value -1 is not a valid value as such but will result in the value 0.15 being used (in meter length scale and kilogram mass scale or the equivalent if other units are used).

Declaration	float physxVehicleEngine:dampingRateFullThrottle = -1
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetDampingRateZeroThrottleClutchDisengagedAttr

(

)

const

Damping rate of engine when no throttle is applied and the clutch is disengaged (units: torque * seconds = mass * distance * distance / seconds).

See attribute "dampingRateFullThrottle" for information about the effect of the value. The value has to be greater or equal 0.

Note: the default value -1 is not a valid value as such but will result in the value 0.35 being used (in meter length scale and kilogram mass scale or the equivalent if other units are used).

PHYSXSCHEMA_API UsdAttribute GetDampingRateZeroThrottleClutchEngagedAttr

(

)

const

Damping rate of engine when no throttle is applied and the clutch is engaged (units: torque * seconds = mass * distance * distance / seconds).

See attribute "dampingRateFullThrottle" for information about the effect of the value. The value has to be greater or equal 0.

Note: the default value -1 is not a valid value as such but will result in the value 2.0 being used (in meter length scale and kilogram mass scale or the equivalent if other units are used).

Declaration	float physxVehicleEngine:dampingRateZeroThrottleClutchEngaged = -1
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetIdleRotationSpeedAttr

(

)

const

Rotation speed of the engine when idling (units: radians / seconds).

The value has to be greater or equal 0.

Declaration	float physxVehicleEngine:idleRotationSpeed = 0
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetMaxRotationSpeedAttr

(

)

const

Maximum rotation speed of the engine (units: radians / seconds).

The value has to be greater or equal 0.

Declaration	float physxVehicleEngine:maxRotationSpeed = 600
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetMoiAttr

(

)

const

The moment of inertia of the engine around the axis of rotation (units: mass * distance * distance).

The value has to be positive.

Note: if not defined, the value 1.0 will be used. This default value is in meter length scale and kilograms and will get adjusted if other units are used.

Declaration	float physxVehicleEngine:moi
C++ Type	float
Usd Type	SdfValueTypeNames->Float

PHYSXSCHEMA_API UsdAttribute GetPeakTorqueAttr

(

)

const

Maximum torque available to apply to the engine when the accelerator pedal is at maximum (units: mass * distance * distance / seconds / seconds).

The value has to be greater or equal 0.

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

Note: the default value -1 is not a valid value as such but will result in the value 500.0 being used (in meter length scale and kilogram mass scale or the equivalent if other units are used).

Declaration	float physxVehicleEngine:peakTorque = -1
C++ Type	float
Usd Type	SdfValueTypeNames->Float

static PHYSXSCHEMA_API const TfTokenVector& GetSchemaAttributeNames ( bool  includeInherited = true )

static

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes.

Does not include attributes that may be authored by custom/extended methods of the schemas involved.

PHYSXSCHEMA_API UsdAttribute GetTorqueCurveAttr

(

)

const

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

Note: the normalized engine speed is the x-axis of the graph, while the normalized torque is the y-axis of the graph. No more than 8 data points are supported.

Note: if not defined, the following values will be used: [(0.0, 0.8), (0.33, 1.0), (1.0, 0.8)].

Declaration	float2[] physxVehicleEngine:torqueCurve
C++ Type	VtArray<GfVec2f>
Usd Type	SdfValueTypeNames->Float2Array
