move(self: omni.physxzerogravity.bindings._physXZeroGravity.PhysxZeroGravity, path: str, delta_translation: carb._carb.Float3, start: bool, lock_rotation: bool) → bool

Attempts to move a physics object to a new relative position

Parameters

set_dropping_on_prim(self: omni.physxzerogravity.bindings._physXZeroGravity.PhysxZeroGravity, isDropping: bool, primPath: str) → int

Sets the dropping mode on a rigid body at the specified prim path

set_dropping_on_selected(self: omni.physxzerogravity.bindings._physXZeroGravity.PhysxZeroGravity, isDropping: bool) → int

set_physics_authoring_mode(self: omni.physxzerogravity.bindings._physXZeroGravity.PhysxZeroGravity, state: bool, layerName: str) → None

Sets the physics authoring mode. When enabled this runs the custom collision filtering logic to prevent objects from exploding when they are intersecting in their rest state

Parameters
