class ForceFieldSchemaPhysxForceFieldDragAPI : public usdrt::UsdAPISchemaBase
A force field that slows rigid bodies by generating a force that is opposite to their velocity direction using the forumula f = -linear * v - square * v^2.
Public Functions
-
inline explicit ForceFieldSchemaPhysxForceFieldDragAPI(const UsdPrim &prim = UsdPrim(), const TfToken &name = TfToken())

prim
with namename
. Equivalent to ForceFieldSchemaPhysxForceFieldDragAPI::Get( prim.GetStage(), prim.GetPath().AppendProperty( “physxForceField:name”));.for a valid

Public Static Functions
-
static inline ForceFieldSchemaPhysxForceFieldDragAPI Apply(const UsdPrim &prim, const TfToken &name)
Applies this multiple-apply API schema to the given
prim
along with the given instance name,name
.This information is stored by adding “PhysxForceFieldDragAPI:<i>name</i>” to the token-valued, listOp metadata apiSchemas on the prim. For example, if
name
is ‘instance1’, the token ‘PhysxForceFieldDragAPI:instance1’ is added to ‘apiSchemas’.See also

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