Detailed Description

A linear force field that attracts and/or repels rigid bodies from a line, defined by a point and direction vector, depending on the function coefficients.

Positive values attract and negative values repel. The net force on the rigid body is calculated using f = constant + linear * r + inverseSquare / r^2, where r is the distance to the closest point on the line.

Constructor & Destructor Documentation

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

Construct a ForceFieldSchemaPhysxForceFieldLinearAPI on UsdPrim prim with name name .

Equivalent to ForceFieldSchemaPhysxForceFieldLinearAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( "physxForceField:name"));

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

Definition at line 78 of file physxForceFieldLinearAPI.h.

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

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

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

Member Function Documentation

FORCEFIELDSCHEMA_API UsdSchemaKind _GetSchemaKind ( ) const
overrideprotected

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind
static FORCEFIELDSCHEMA_API ForceFieldSchemaPhysxForceFieldLinearAPI 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 "PhysxForceFieldLinearAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is 'instance1', the token 'PhysxForceFieldLinearAPI:instance1' is added to 'apiSchemas'.

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

static FORCEFIELDSCHEMA_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.

FORCEFIELDSCHEMA_API UsdAttribute CreateConstantAttr ( VtValue const &  defaultValue = VtValue(),

See GetConstantAttr(), 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 
) const

See GetDirectionAttr(), 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 
) const

See GetInverseSquareAttr(), 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.

FORCEFIELDSCHEMA_API UsdAttribute CreateLinearAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetLinearAttr(), 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 FORCEFIELDSCHEMA_API ForceFieldSchemaPhysxForceFieldLinearAPI Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a ForceFieldSchemaPhysxForceFieldLinearAPI 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>.physxForceField:name .

This is shorthand for the following:

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