Detailed Description

The PhysicsLimitAPI can be applied to a PhysicsJoint and will restrict the movement along an axis.

PhysicsLimitAPI is a multipleApply schema: The PhysicsJoint can be restricted along "transX", "transY", "transZ", "rotX", "rotY", "rotZ", "distance". Setting these as a multipleApply schema TfToken name will define the degree of freedom the PhysicsLimitAPI is applied to. Note that if the low limit is higher than the high limit, motion along this axis is considered locked.

Constructor & Destructor Documentation

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

Construct a UsdPhysicsLimitAPI on UsdPrim prim with name name .

Equivalent to UsdPhysicsLimitAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( "limit:name"));

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

Definition at line 80 of file limitAPI.h.

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

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

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

Definition at line 89 of file limitAPI.h.

Destructor.

Member Function Documentation

USDPHYSICS_API UsdSchemaType _GetSchemaType ( ) const
overrideprotected

Returns the type of schema this class belongs to.

See Also
UsdSchemaType
static USDPHYSICS_API UsdPhysicsLimitAPI 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 "PhysicsLimitAPI:<i>name</i>" to the token-valued, listOp metadata apiSchemas on the prim. For example, if name is 'instance1', the token 'PhysicsLimitAPI:instance1' is added to 'apiSchemas'.

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

USDPHYSICS_API UsdAttribute CreateHighAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetHighAttr(), 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.

USDPHYSICS_API UsdAttribute CreateLowAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetLowAttr(), 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 USDPHYSICS_API UsdPhysicsLimitAPI Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a UsdPhysicsLimitAPI 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>.limit:name .

This is shorthand for the following:

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

Return a UsdPhysicsLimitAPI with name name holding the prim prim.

Shorthand for UsdPhysicsLimitAPI(prim, name);

USDPHYSICS_API UsdAttribute GetHighAttr ( ) const

Upper limit.

Units: degrees or distance depending on trans or rot axis applied to. inf means not limited in positive direction.

Declaration float physics:high = inf
C++ Type float
Usd Type SdfValueTypeNames->Float
USDPHYSICS_API UsdAttribute GetLowAttr ( ) const

Lower limit.

Units: degrees or distance depending on trans or rot axis applied to. -inf means not limited in negative direction.

Declaration float physics:low = -inf
C++ Type float
Usd Type SdfValueTypeNames->Float
TfToken GetName ( ) const
inline

Returns the name of this multiple-apply schema instance.

Definition at line 109 of file limitAPI.h.

static USDPHYSICS_API const TfTokenVector& GetSchemaAttributeNames ( bool  includeInherited = true,
const TfToken  instanceName = TfToken() 
)
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.

static USDPHYSICS_API bool IsPhysicsLimitAPIPath ( const SdfPath &  path,
TfToken *  name 
)
static

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

If so, it stores the instance name of the schema in name and returns true. Otherwise, it returns false.

static USDPHYSICS_API bool IsSchemaPropertyBaseName ( const TfToken &  baseName)
static

Checks if the given name baseName is the base name of a property of PhysicsLimitAPI.
