Detailed Description

PhysxSceneQuasistaticAPI defines quasistatic mode for simulation.

The API must be applied to a UsdPhysics.PhysicsScene prim.

In this mode actors are simulated/moved by the physics engine by obeying external forces and constraints as usual, but they do not accumulate momentum. So that e.g. falling due to gravity is with constant speed, and motion stops as soon as external forces cease to apply. There is no conservation of momentum.

By default all actors belonging to the scene have this behavior unless the collection does have the includes defined, then the collection definition does have a precendence.

Constructor & Destructor Documentation

PhysxSchemaPhysxSceneQuasistaticAPI ( const UsdPrim &  prim = UsdPrim())
inlineexplicit

Construct a PhysxSchemaPhysxSceneQuasistaticAPI on UsdPrim prim .

Equivalent to PhysxSchemaPhysxSceneQuasistaticAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 82 of file physxSceneQuasistaticAPI.h.

PhysxSchemaPhysxSceneQuasistaticAPI ( const UsdSchemaBase &  schemaObj)
inlineexplicit

Construct a PhysxSchemaPhysxSceneQuasistaticAPI on the prim held by schemaObj .

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

Definition at line 90 of file physxSceneQuasistaticAPI.h.

Member Function Documentation

PHYSXSCHEMA_API UsdSchemaKind _GetSchemaKind ( ) const
overrideprotected

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind
static PHYSXSCHEMA_API PhysxSchemaPhysxSceneQuasistaticAPI Apply ( const UsdPrim &  prim)
static

Applies this single-apply API schema to the given prim.

This information is stored by adding "PhysxSceneQuasistaticAPI" to the token-valued, listOp metadata apiSchemas on the prim.

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

UsdPrim::RemoveAPI()
static PHYSXSCHEMA_API bool CanApply ( const UsdPrim &  prim,
std::string *  whyNot = nullptr 
)
static

Returns true if this single-apply API schema can be applied to the given prim.

If this schema can not be a applied to 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.

PHYSXSCHEMA_API UsdAttribute CreateEnableQuasistaticAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetEnableQuasistaticAttr(), 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 PhysxSchemaPhysxSceneQuasistaticAPI Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a PhysxSchemaPhysxSceneQuasistaticAPI 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. This is shorthand for the following:

* PhysxSchemaPhysxSceneQuasistaticAPI(stage->GetPrimAtPath(path));
*
PHYSXSCHEMA_API UsdAttribute GetEnableQuasistaticAttr ( ) const

Whether the actors should behave quasistatic or not.

Declaration bool physxSceneQuasistatic:enableQuasistatic = 1
C++ Type bool
Usd Type SdfValueTypeNames->Bool
PHYSXSCHEMA_API UsdCollectionAPI GetQuasistaticActorsCollectionAPI ( ) const

Return the UsdCollectionAPI interface used for defining what prims belong to the quasistatic API.

static PHYSXSCHEMA_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.
