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() [1/2]

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() [2/2]

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.

◆ ~UsdPhysicsLimitAPI()

virtual USDPHYSICS_API ~UsdPhysicsLimitAPI ( )
virtual

Destructor.

Member Function Documentation

◆ _GetSchemaKind()

USDPHYSICS_API UsdSchemaKind _GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See also
UsdSchemaKind

Reimplemented from UsdAPISchemaBase.

◆ Apply()

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.

◆ CanApply()

static USDPHYSICS_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.

◆ CreateHighAttr()

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

See GetHighAttr(), 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.

◆ CreateLowAttr()

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

See GetLowAttr(), 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.

◆ Get() [1/2]

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);

◆ Get() [2/2]

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);

◆ GetAll()

static USDPHYSICS_API std::vector<UsdPhysicsLimitAPI> GetAll ( const UsdPrim prim)
static

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

◆ GetHighAttr()

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

◆ GetLowAttr()

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

◆ GetName()

TfToken GetName ( ) const
inline

Returns the name of this multiple-apply schema instance.

Definition at line 115 of file limitAPI.h.

◆ GetSchemaAttributeNames() [1/2]

static USDPHYSICS_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.

◆ GetSchemaAttributeNames() [2/2]

static USDPHYSICS_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.

◆ IsPhysicsLimitAPIPath()

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.

◆ IsSchemaPropertyBaseName()

static USDPHYSICS_API bool IsSchemaPropertyBaseName ( const TfToken baseName)
static

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