Inputs
- OutsideTransition (in all games since
) !FGD - Usually this is automatically done by a trigger_transition when the map changes, but it can be done manually as well. It sends the entity into a "dormant" state where it is disabled even though the entity may still think it is active. This is done in the case that the player decides to go back to a previous map, where the entity will then become non-dormant again.
- Activate
- Begin the follow behavior.
- Deactivate
- Cease the following behavior.
