Detailed Description

Describes a braking system for a vehicle by specifying which wheels are connected to the brake control and by defining the brake torque that gets applied to those wheels.

Currently, up to two braking systems are supported. Use the instance name TfToken "brakes0" and "brakes1" of this multipleApply schema to distinguish between the two braking systems. Note that system "brakes0" will be coupled to the brake control brake0 while system "brakes1" will be coupled to the brake control brake1 (see PhysxVehicleControllerAPI for the brake controls). An example for using two systems is to provide brake and handbrake control (the former applying brake torque to all wheels and the latter applying brake torque to the rear wheels only). This API schema 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

PhysxSchemaPhysxVehicleBrakesAPI ( const UsdPrim &  prim = UsdPrim(),
const TfToken &  name = TfToken() 
)
inlineexplicit

Construct a PhysxSchemaPhysxVehicleBrakesAPI on UsdPrim prim with name name .

Equivalent to PhysxSchemaPhysxVehicleBrakesAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( "physxVehicleBrakes:name"));

for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 83 of file physxVehicleBrakesAPI.h.

PhysxSchemaPhysxVehicleBrakesAPI ( const UsdSchemaBase &  schemaObj,
const TfToken &  name 
)
inlineexplicit

Construct a PhysxSchemaPhysxVehicleBrakesAPI on the prim held by schemaObj with name name.

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

Member Function Documentation

PHYSXSCHEMA_API UsdSchemaKind _GetSchemaKind ( ) const

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind
static PHYSXSCHEMA_API PhysxSchemaPhysxVehicleBrakesAPI Apply ( const UsdPrim &  prim,
const TfToken &  name 
)
static

Applies this multiple-apply API schema to the given prim along with the given instance name, name.

This information is stored by adding "PhysxVehicleBrakesAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is 'instance1', the token 'PhysxVehicleBrakesAPI:instance1' is added to 'apiSchemas'.

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

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

Returns true if this multiple-apply API schema can be applied, with the given instance name, name, to the given prim.

If this schema can not be a applied 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 CreateMaxBrakeTorqueAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetMaxBrakeTorqueAttr(), 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 CreateTorqueMultipliersAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetTorqueMultipliersAttr(), 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 PhysxSchemaPhysxVehicleBrakesAPI Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a PhysxSchemaPhysxVehicleBrakesAPI 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. path must be of the format <path>.physxVehicleBrakes:name .

This is shorthand for the following:

* TfToken name = SdfPath::StripNamespace(path.GetToken());
* stage->GetPrimAtPath(path.GetPrimPath()), name);
*
static PHYSXSCHEMA_API PhysxSchemaPhysxVehicleBrakesAPI Get ( const UsdPrim &  prim,
const TfToken &  name 
)
static

Return a PhysxSchemaPhysxVehicleBrakesAPI with name name holding the prim prim.

Shorthand for PhysxSchemaPhysxVehicleBrakesAPI(prim, name);

static PHYSXSCHEMA_API std::vector<PhysxSchemaPhysxVehicleBrakesAPI> GetAll ( const UsdPrim &  prim)
static

Return a vector of all named instances of PhysxSchemaPhysxVehicleBrakesAPI on the given prim.

PHYSXSCHEMA_API UsdAttribute GetMaxBrakeTorqueAttr ( ) const

The maximum brake torque that can be generated by the braking system (units: mass * distance * distance / seconds / seconds).

Has to be greater or equal zero. For braking system "brakes0", the brake torque applied to wheels[i] will be defined by maxBrakeTorque * torqueMultipliers[i] * physxVehicleController:brake0 (see PhysxVehicleControllerAPI).

Declaration float maxBrakeTorque = 0
C++ Type float
Usd Type SdfValueTypeNames->Float
TfToken GetName ( ) const
inline

Returns the name of this multiple-apply schema instance.

Definition at line 118 of file physxVehicleBrakesAPI.h.

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.

static PHYSXSCHEMA_API TfTokenVector GetSchemaAttributeNames ( bool  includeInherited,
const TfToken &  instanceName 
)
static

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

Does not include attributes that may be authored by custom/extended methods of the schemas involved. The names returned will have the proper namespace prefix.

PHYSXSCHEMA_API UsdAttribute GetTorqueMultipliersAttr ( ) const

Defines how much of the max brake torque can be delivered to the wheels that are connected to the braking system.

The values are unitless multipliers and have to be greater or equal to zero. See maxBrakeTorque for how these multipliers affect the brake torque applied to a wheel. 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, a multiplier value of 1 will be used for all connected wheels.

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

List of indices, referencing the wheels that receive brake torque.

The indices refer to the attribute "index" of PhysxVehicleWheelAttachmentAPI. If not specified, each wheel will receive a brake torque using a torque multiplier of 1 (see attribute torqueMultipliers).

Declaration int[] wheels
C++ Type VtArray<int>
Usd Type SdfValueTypeNames->IntArray
static PHYSXSCHEMA_API bool IsPhysxVehicleBrakesAPIPath ( const SdfPath &  path,
TfToken *  name 
)
static

Checks if the given path path is of an API schema of type PhysxVehicleBrakesAPI.
