Construct a UsdPhysicsScene on UsdPrim prim
.
Equivalent to UsdPhysicsScene::Get(prim.GetStage(), prim.GetPath()) for a valid prim
, but will not immediately throw an error for an invalid prim
|
inlineexplicit |
Construct a UsdPhysicsScene on the prim held by schemaObj
.
Should be preferred over UsdPhysicsScene(schemaObj.GetPrim()), as it preserves SchemaBase state.

Attempt to ensure a UsdPrim adhering to this schema at path
is defined (according to UsdPrim::IsDefined()) on this stage.
If a prim adhering to this schema at path
is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path
at the current EditTarget. Author SdfPrimSpec s with specifier
== SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.
The given path must be an absolute prim path that does not contain any variant selections.
If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.
Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

Return a UsdPhysicsScene 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:
USDPHYSICS_API UsdAttribute GetGravityDirectionAttr | ( | ) | const |
Gravity direction vector in simulation world space.
Will be normalized before use. A zero vector is a request to use the negative upAxis. Unitless.
Declaration | vector3f physics:gravityDirection = (0, 0, 0) |
C++ Type | GfVec3f |
Usd Type | SdfValueTypeNames->Vector3f |
USDPHYSICS_API UsdAttribute GetGravityMagnitudeAttr | ( | ) | const |
Gravity acceleration magnitude in simulation world space.
A negative value is a request to use a value equivalent to earth gravity regardless of the metersPerUnit scaling used by this scene. Units: distance/time/time.
Declaration | float physics:gravityMagnitude = -inf |
C++ Type | float |
Usd Type | SdfValueTypeNames->Float |

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.
