B2Action_ChangePosture

• Description
  * ===============
  * Drives a character's posture transition (standing, sitting, vehicle, carried, etc.), including animation/transition selection and vehicle-exit safety checks.
  * ===============
  * Param:
  * S1: target posture id to transition to
  * S2: -
  * F1: -
  * F2: -
  * Note:
  * OnInit(): resolves the target posture state/slot info and requests async preload of the posture and transition animations.
  * OnPlay(): starts the posture change animation and performs vehicle-exit validation.
  * OnFinish(): applies the resolved posture state to the character, restores animation transforms, and handles vehicle exit notifications/teleports.
  * OnCanceled(): stops the in-progress posture animation and clears the pending posture id.
  * OnTick(): accumulates elapsed posture animation time.

Property	Type	Description	Metadata
PostureId	FName	Target posture id to transition into, read from the action params
ChangePostureState	FB1PostureState	Resolved posture state (id, direction, target entity, slot) to apply on finish
PostureAnimName	FName	Montage row name resolved for the target posture animation
PostureAnimId	FName	Animation id resolved for the target posture animation
TransitionAnimId	FName	Animation id for transitioning between the current and target posture, if any
TransitionAnimName	FName	Montage row name resolved for the transition animation
CurrentAnimTime	float	Elapsed time since the posture animation started playing
bIsOverrideAnim	bool	Whether a one-time posture override animation is being used instead of the normally resolved one
bIsCancelCondition	bool	Whether this action currently allows cancellation (set when a blocking vehicle-exit condition occurs)
bUseSafeExitLocation	bool	Whether to teleport the character to SafeExitLocation on finish
SafeExitLocation	FVector	Precomputed safe location to teleport the character to when exiting a vehicle
bIsDriverExit	bool	Whether this posture change corresponds to the vehicle driver exiting
bIsPassengerExit	bool	Whether this posture change corresponds to a vehicle passenger exiting
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)
