class ForceFieldSchemaPhysxForceFieldDragAPI : public usdrt::UsdAPISchemaBase

A force field that slows rigid bodies by generating a force that is opposite to their velocity direction using the forumula f = -linear * v - square * v^2.

Public Functions

inline explicit ForceFieldSchemaPhysxForceFieldDragAPI(const UsdPrim &prim = UsdPrim(), const TfToken &name = TfToken())

Construct a ForceFieldSchemaPhysxForceFieldDragAPI on UsdPrim prim with name name . Equivalent to ForceFieldSchemaPhysxForceFieldDragAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( “physxForceField:name”));.

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

inline explicit ForceFieldSchemaPhysxForceFieldDragAPI(const UsdSchemaBase &schemaObj, const TfToken &name)

Construct a ForceFieldSchemaPhysxForceFieldDragAPI on the prim held by schemaObj with name name . Should be preferred over ForceFieldSchemaPhysxForceFieldDragAPI(schemaObj.GetPrim(), name), as it preserves SchemaBase state.

inline virtual ~ForceFieldSchemaPhysxForceFieldDragAPI()

Destructor.

inline operator bool() const

Boolean operator.

Returns

Return true if the contained prim is has this api schema applied using HasAPI, and false otherwise.

inline TfToken GetName() const

Returns the name of this multiple-apply schema instance.

inline UsdAttribute GetMinimumSpeedAttr() const

Drag forces are not applied below this minimum speed.

Declaration

float physxForceFieldDrag:minimumSpeed = 0

C++ Type

float

Usd Type

SdfValueTypeNames->Float

inline UsdAttribute CreateMinimumSpeedAttr() const

See GetMinimumSpeedAttr(), and also Create vs Get Property Methods 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.

inline UsdAttribute GetLinearAttr() const

linear sets a force that varies proportionally with the speed of the rigid body.

Declaration

float physxForceFieldDrag:linear = 0

C++ Type

float

Usd Type

SdfValueTypeNames->Float

inline UsdAttribute CreateLinearAttr() const

See GetLinearAttr(), and also Create vs Get Property Methods 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.

inline UsdAttribute GetSquareAttr() const

square computes a force the varies with the square of the speed of the rigid body.

Declaration

float physxForceFieldDrag:square = 0

C++ Type

float

Usd Type

SdfValueTypeNames->Float

inline UsdAttribute CreateSquareAttr() const

See GetSquareAttr(), and also Create vs Get Property Methods 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.

UsdPrim GetPrim() const

Return this schema object’s held prim.

SdfPath GetPath() const

Return the SdfPath to this schema object’s held prim.

Public Static Functions

static inline ForceFieldSchemaPhysxForceFieldDragAPI Apply(const UsdPrim &prim, const TfToken &name)

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

This information is stored by adding “PhysxForceFieldDragAPI:<i>name</i>” to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is ‘instance1’, the token ‘PhysxForceFieldDragAPI:instance1’ is added to ‘apiSchemas’.

Returns

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

Public Static Attributes

static const UsdSchemaType schemaType = UsdSchemaType::MultipleApplyAPI

Compile time constant representing what kind of schema this class is.

Protected Functions

inline const TfToken &_GetInstanceName() const

Returns the instance name of the API schema object belonging to a multiple-apply API schema.

The returned instance name will be empty for non-applied and single-apply API schemas.
