Detailed Description

Describes a system of graphs to define nonlinear responses to PhysxVehicleControllerAPI command values like accelerator, brake0, brake1 and steer.

The normalized response will be a function of the command value and the longitudinal vehicle speed. The response will be computed by interpolating between the points of the graph and then interpolating those results again between the closest graphs. One example usage of nonlinear command response is a brake pedal that has an almost flat response when tipped slightly but a very strong response from a certain point on. Another example is the steering wheel showing a strong response for a large input at low speed but only a weak response at high speed.

This multipleApply schema can be used to control the response to steering (use instance name TfToken "steer") and braking (use instance name TfTokens "brakes0" or "brakes1"). It can also control the response to the accelerator but only in combination with the basic drive (use instance name TfToken "drive"). Furthermore, this API has to be applied to the appropriate prims to take effect: "steer" has to be applied to a prim that has PhysxVehicleSteeringAPI or PhysxVehicleAckermannSteeringAPI applied. "brakes0"/"brakes1" have to be applied to a prim that has PhysxVehicleBrakesAPI:brakes0/brakes1 applied. "drive" has to be applied to a prim that has PhysxVehicleDriveBasicAPI applied.

Constructor & Destructor Documentation

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

Construct a PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI on UsdPrim prim with name name .

Equivalent to PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( "physxVehicleNCR:name"));

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

Definition at line 90 of file physxVehicleNonlinearCommandResponseAPI.h.

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

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

Should be preferred over PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI(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 PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI 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 "PhysxVehicleNonlinearCommandResponseAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is 'instance1', the token 'PhysxVehicleNonlinearCommandResponseAPI:instance1' is added to 'apiSchemas'.

Returns
A valid PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI object is returned upon success. An invalid (or empty) PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI 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 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.

See GetCommandValuesAttr(), 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.

bool  writeSparsely = false

See GetSpeedResponsesAttr(), 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.

See GetSpeedResponsesPerCommandValueAttr(), 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 PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a PhysxSchemaPhysxVehicleNonlinearCommandResponseAPI 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>.physxVehicleNCR:name .

This is shorthand for the following:

* TfToken name = SdfPath::StripNamespace(path.GetToken());
* stage->GetPrimAtPath(path.GetPrimPath()), name);

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

PHYSXSCHEMA_API UsdAttribute GetCommandValuesAttr ( ) const

The command values to define response graphs for.

Each listed command value (in range [0, 1], steer commands are treated symmetrically) has to point to a graph in speedResponses. The command values refer to steer, brake0 etc. The values have to be strictly increasing. The number of entries has to match the number of entries in speedResponsesPerCommandValue and is limited to 8. Every command value needs at least one entry in speedResponses.

inline

Returns the name of this multiple-apply schema instance.
