B2Action_Surfing

• Description
  * ===============
  * Keeps a character riding a wave while on a surfboard. Turns on the on-board handler's surfing flag and stays active until B1 reports that surfing has ended.
  * ===============
  * Param:
  * S1: -
  * S2: -
  * F1: -
  * F2: -
  * Note:
  * OnInit(): Delegates to FB2Action_Base::OnInit(); no extra data is read from the action.
  * OnB2PreBeginPlay(): When the action was already playing at restore time, sets bRestore and cancels the interaction so surfing is not resumed from a save.
  * CanStartCondition(): Requires a valid self character and movement component, an inactive on-board handler (boarding/disembarking must not be in progress, because the posture check alone can pass during those transitions), and the Surf posture on the posture component.
  * OnPlay(): Turns on the on-board handler's surfing flag; finishes with InvalidSelfEntity if the character or movement component is missing.
  * OnTick(): Finishes the action once the on-board handler reports surfing has stopped, since the surf progress itself is driven by B1 and only reported back through that flag; finishes with InvalidSelfEntity if the character or movement component is missing.
  * OnCanceled(): Turns the on-board handler's surfing flag off, unless the action is being torn down by a restore (bRestore).
  * OnFinish(): Does nothing beyond the restore guard, because normal termination is already driven by B1 notifying B2 that surfing ended.

Property	Type	Description	Metadata
bRestore	bool	whether this action is being resumed mid-play from a save/restore, so redundant toast/UI cleanup and result reporting are skipped
bIsOutOfWaterArea	bool
ActionId	FName	Identifier of this action instance (used for interaction tracking and mission time accounting)
State	EB2ActionState	Current lifecycle state of this action
MergeType	EB2ActionMergeType	Merge type flags for this action (e.g. interaction merge, checked in Finish())
Result	EB2InteractionResult	Result of this action once it stops playing (Finish/Failed/Canceled)
SelfEntityId	FB1EntityId	Entity id performing this action
TargetEntityId	FB1EntityId	Entity id targeted by this action
GrabEntityId	FB1EntityId	Entity id grabbed/carried by self entity for this action
NonTargetLocation	FVector	Location used for script/condition context when there is no target entity
Action	FB1ActionInfo	Action table data (S1/S2/F1/F2, script id lists, etc.) driving this instance
TickCalcValue	float	Accumulated tick delta time since this action started ticking
CurrentNotifyIndex	int32	Index into Action.NotifyScriptIds for the next notify script to run
AsyncLoadAnimInfo	TArray	Animations to async-load for this action's start/notify/tick/finish/cancel scripts
AddActionTimeInterval	float	Interval in seconds between OnTickAddActionExecuteTime() calls
AccumAddActionTime	float	Elapsed time accumulator compared against AddActionTimeInterval
StartActionTickTime	int64	Tick timestamp used to measure elapsed action execution time for mission tracking
ActionKey	FB2ActionKey	Key identifying this action's slot/queue within the interaction system
TimeTaskId	FB1TimeTaskId	Id of the scheduled time task used for delayed Determine/Finish
IsForceCancelable	bool	Whether this action is force-cancelable, copied from Action.IsForceCancelable
IsFirstAction	bool	Marks the first action in an interaction sequence; set on actions[0] by FB2InteractionPlayer::LinkActions(), read by FB2ActionPlayer
bMultiFlag	bool	Set by looping actions (PlayAnim, BookRead, Eat, WaitTalkSequence) once a loop iteration completes; read/reset by FB2ActionPlayer to gate multi-interaction selection
TalkInstanceId	FB1TalkInstanceId	Id of the talk instance this action is linked to, set externally by FB2InteractionPlayer::LinkActions()
TalkSubjectEntityId	FB1EntityId	Entity id of the talk subject linked to this action, set externally by FB2InteractionPlayer::LinkActions()/OnTalkSpaceParamChanged()
bIsWaitFinishEvent	bool	Cached copy of Action.IsWaitFinishAction taken at Init(); read directly by FB2ActionPlayer for sequencing (the IsWaitFinishAction() getter instead reads Action.IsWaitFinishAction live)
AutoInsertType	EB2ActionAutoInsertType	Type of action that was auto-inserted before this one (e.g. WalkTo, ChangePosture)
