Saving and Restoring States

Saving Active State

• The guid of the active state can be easily retrieved for serialization by using GetNestedActiveStateGuid from the state machine instance.

Loading Active State

• Use LoadFromState from the state machine instance and provide the guid of the active state.
• The state machine will automatically set initial states of all affected state machines.

Saving and Restoring All States

• If the current state of a nested state machine which doesn't contain the active state is important use GetAllCurrentStateGuids and LoadFromMultipleStates from the state machine instance.
  • Normally nested state machines clear their state on exit. You may use bReuseCurrentState and bReuseIfNotEndState on state machine nodes to change this behavior.

General Serialization

• If you need to save variables you've added to the state machine blueprint you will need to implement your own serializer for this as you would with any other Blueprint.
