Detailed Description

PhysX schema API that applies a force and torque to a rigid body (UsdGeom.Xformable with UsdPhysicsRigidBodyAPI).

The API can be applied to either:

• The rigid-body Xformable, in which case the force is applied at the body's center of mass.
• To an UsdGeom.Xformable that is a child of the rigid-body Xformable, in which case the force is applied at the location defined by the Xformable.

The worldFrameEnabled flag defines what coordinate frame the force and torque are expressed in. Note that any scale transform operations will only affect the force and torque values if on "acceleration" mode.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in PhysxSchemaTokens. So to set an attribute to the value "rightHanded", use PhysxSchemaTokens->rightHanded as the value.

Constructor & Destructor Documentation

PhysxSchemaPhysxForceAPI ( const UsdPrim &  prim = UsdPrim() )

inlineexplicit

Construct a PhysxSchemaPhysxForceAPI on UsdPrim prim .

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

Definition at line 81 of file physxForceAPI.h.

PhysxSchemaPhysxForceAPI ( const UsdSchemaBase &  schemaObj )

inlineexplicit

Construct a PhysxSchemaPhysxForceAPI on the prim held by schemaObj .

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

Definition at line 89 of file physxForceAPI.h.

Destructor.

Member Function Documentation

PHYSXSCHEMA_API UsdSchemaType _GetSchemaType ( ) const

overrideprotected

Returns the type of schema this class belongs to.

UsdSchemaType

static PHYSXSCHEMA_API PhysxSchemaPhysxForceAPI Apply ( const UsdPrim &  prim )

static

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

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

Returns

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

static PHYSXSCHEMA_API PhysxSchemaPhysxForceAPI Get ( const UsdStagePtr &  stage, const SdfPath &  path  )

static

Return a PhysxSchemaPhysxForceAPI 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:

*  PhysxSchemaPhysxForceAPI(stage->GetPrimAtPath(path));
*  

PHYSXSCHEMA_API UsdAttribute GetForceAttr

(

)

const

Force to apply defined in global or local frame depending on worldFrameEnabled.

The force is applied at the position defined by the relative transform to the parent rigid-body Xformable, or at the body's center of mass if the API is applied directly to a rigid-body Xformable. For units see mode attribute. Range: (-inf, inf)

Declaration	vector3f physxForce:force = (0, 0, 0)
C++ Type	GfVec3f
Usd Type	SdfValueTypeNames->Vector3f

PHYSXSCHEMA_API UsdAttribute GetForceEnabledAttr

(

)

const

Boolean defining whether the force and torque are enabled or disabled.

Declaration	bool physxForce:forceEnabled = 1
C++ Type	bool
Usd Type	SdfValueTypeNames->Bool

PHYSXSCHEMA_API UsdAttribute GetModeAttr

)

const

Force mode, can be either a force or an acceleration.

force - units: (linear) mass * distance / seconds^2, i.e. a force (angular) mass * distance * distance / time^2, i.e. a torque acceleration - units: (linear) distance / seconds^2, i.e. a linear acceleration. (angular) degrees / seconds^2, i.e. an angular acceleration.

Declaration	uniform token physxForce:mode = "acceleration"
