classmethod add_multiple_smart_objects(smart_object_actors) → bool

Adds to the simulation all smart objects for multiple actors.

Parameters:

smart_object_actors (Array[Actor]) – The actors containing the smart objects to add to the simulation

Returns:

True if the requested operation succeeded; false otherwise

Return type:

bool

classmethod add_or_remove_multiple_smart_objects(smart_object_actors, add) → bool

Adds to the simulation all smart objects for multiple actors or removes them according to ‘bAdd’. note: Removing a smart object from the simulation will interrupt all active interactions.

Parameters:

  • smart_object_actors (Array[Actor]) – The actors containing the smart objects to add or remove from the simulation

  • add (bool) – Whether the smart objects should be added or removed from the simulation

Returns:

True if all actors were valid and the requested operation succeeded; false otherwise

Return type:

bool
