Detailed Description

Describes which wheels of a vehicle are driven as well as the distribution of the drive torque among those wheels.

Has to be applied to a prim with PhysxVehicleAPI applied. Can only be used for vehicles that have a drive (see PhysxVehicleDriveBasicAPI or PhysxVehicleDriveStandardAPI).

Constructor & Destructor Documentation

PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI ( const UsdPrim &  prim = UsdPrim())
inlineexplicit

Construct a PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI on UsdPrim prim .

Equivalent to PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI::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 physxVehicleMultiWheelDifferentialAPI.h.

PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI ( const UsdSchemaBase &  schemaObj)
inlineexplicit

Construct a PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI on the prim held by schemaObj .

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

Member Function Documentation

PHYSXSCHEMA_API UsdSchemaKind _GetSchemaKind ( ) const
overrideprotected

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind
static PHYSXSCHEMA_API PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI Apply ( const UsdPrim &  prim)
static

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

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

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

static PHYSXSCHEMA_API bool CanApply ( const UsdPrim &  prim,
std::string *  whyNot = nullptr 
)
static

Returns true if this single-apply API schema can be applied to the given prim.

If this schema can not be a applied to the prim, this returns false and, if provided, populates whyNot with the reason it can not be applied.

Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.

PHYSXSCHEMA_API UsdAttribute CreateAverageWheelSpeedRatiosAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetAverageWheelSpeedRatiosAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create.

If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

PHYSXSCHEMA_API UsdAttribute CreateTorqueRatiosAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetTorqueRatiosAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create.

If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

PHYSXSCHEMA_API UsdAttribute CreateWheelsAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetWheelsAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create.

If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

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

Return a PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI 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:

*
PHYSXSCHEMA_API UsdAttribute GetAverageWheelSpeedRatiosAttr ( ) const

Defines how the speeds of the driven wheels get weighted when computing the average wheel speed at the clutch (for computing clutch slip).

The provided ratios must be in range [0, 1] and under normal circumstances sum up to 1. If the attribute is defined, then the length of the array needs to match the length of the "wheels" array. If the attribute is not defined, the wheel speeds of all driven wheels will get weighted equally.

Note: if a vehicle is using a PhysxVehicleDriveBasicAPI drive, then this attribute should not be used.

Declaration float[] physxVehicleMultiWheelDifferential:averageWheelSpeedRatios
C++ Type VtArray<float>
Usd Type SdfValueTypeNames->FloatArray
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 GetTorqueRatiosAttr ( ) const

Defines how the drive torque should get distributed among the wheels specified in the "wheels" attribute.

The provided ratios must be in range [-1, 1] and under normal circumstances the absolute values should sum up to 1. If the attribute is defined, then the length of the array needs to match the length of the "wheels" array. If the attribute is not defined, the torque will get split equally among all driven wheels.

Declaration float[] physxVehicleMultiWheelDifferential:torqueRatios
C++ Type VtArray<float>
Usd Type SdfValueTypeNames->FloatArray
PHYSXSCHEMA_API UsdAttribute GetWheelsAttr ( ) const

List of indices, referencing the wheels that are driven (receiving torque from the engine).

The indices refer to the attribute "index" of PhysxVehicleWheelAttachmentAPI.

Declaration int[] physxVehicleMultiWheelDifferential:wheels
C++ Type VtArray<int>
Usd Type SdfValueTypeNames->IntArray
