A property is a holder for function callbacks into the internals of MotionBuilder.

A property is a container for callback functions that inherit from the FBProperty class. Most objects in MotionBuilder contain properties instead of variables. They exist in various forms, each form representing a data type that the property is representing.

You cannot instantiate FBProperty objects. To reference a property:

• Use an instance of an FBComponent object. The methods FBComponent::PropertyCreate and FBComponent::PropertyRemove can be used to modify an object's set of properties. When accessing a FBProperty object via its containing object, you can get or set (assuming it is not read-only) its value directly: myObject.Visibility = True.
• FBPropertyManager exists in all FBComponent objects and contains an array of all the registered properties. Use FBProperty::Find to find a property by name. When accessing a property reference directly, you can get its value via it's 'Data' member.

  myProp = myObject.PropertyList.Find( 'Visibility' )
  if myProp: myProp.Data = True
