class | UsdSchemaRegistry |
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).

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

Construct a PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI on the prim held by schemaObj

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

Destructor.

Returns the kind of schema this class belongs to.

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 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.

Return a PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI holding the prim adhering to this schema at path

.
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.

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.

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