B2Action_BookRead

• Description
  * ===============
  * Plays synchronized reader/book loop montages while a character reads a carriable book object, accumulating elapsed reading time until the book's total read time (or homework progress) completes, then finishes with the book's finish script.
  * ===============
  * Param:
  * S1: RootAnimId - animation id played on the reading character (self)
  * S2: BookAnimId - animation id played on the book object (target)
  * F1: -
  * F2: -
  * Note:
  * OnInit(): resolves BookDtId/BookAnimId, queues async anim loads for both self and the book, and computes ProgressTime.
  * OnPlay(): resets loop/tick state, runs the book's start script, and starts the Default-section loop montage.
  * OnFinish(): runs the book's finish script, notifies FB2MissionComponent of the completed read, and resets the root montage delegates.
  * OnCanceled(): plays the End section montage if the loop hadn't already reached End.
  * OnTick(): accumulates elapsed reading ticks while in the Loop section and finishes (via End section) once total read time or homework progress completes.

Property	Type	Description	Metadata
BookReadTickTime	int64	Accumulated elapsed reading time in ticks, compared against the book's TotalReadTime to know when to end the loop
BookDtId	FName	Book data table id of the target carriable book, resolved at init and used for all book table lookups
BookAnimId	FName	Book-side animation id (from Action.S2), used to resolve the book object's montage
BookAnimMontageName	FName	Resolved montage row id for the book object's animation, used to play the montage
ProgressTime	float	Total time this reading session should take, computed from the book's TotalReadTime and current game time scale
AnimationId	FName	Animation id to play, resolved via the overridable GetAnimationId() hook
LoopCount	int32	Requested number of times to play the montage's Loop section (0 normalized to 1, -1 means infinite)
RemainLoopCount	int32	Remaining loop iterations, decremented each time the Loop section finishes; drives when looping stops
StartLocation	FVector	Referenced in GetLogString() for debug logging, but never assigned by this class or any subclass - the log always shows the zero-vector default
StartRotation	FRotator	Referenced in GetLogString() for debug logging, but never assigned by this class or any subclass - the log always shows the zero-rotator default
AnimMontageName	FName	Resolved montage asset name used to play/track the animation, set by SetAnim()
SectionName	FName	Current montage section of MAIN ANIMATION (Default/Loop/End), tracked via montage delegates and used to drive finish/cancel decisions
PlayingComponentName	FName	Anim component the montage is played on (e.g. Root vs. other), resolved by SetAnim(). SetAnim() clears this on entry, so it stays None whenever the resolve fails; a non-None value means the latest resolve succeeded.
TotalPlayLength	float	Total play length of the resolved montage, used in progress-time and one-loop-length calculations
LoopPlayLength	float	Play length of a single loop of the resolved montage, used in progress-time calculation
RateScale	float	Playback rate scale of the resolved montage, used in progress-time calculation
Paused	bool	Whether the montage is currently held in a paused blend state
Phase	EB2PlayAnimPhase	Phase of PlayAnim Action
AddOnAnimData	FB2AddOnAnimData	AddOnAnim Data
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)
