Functions

  Type Name Description
Public function Virtual void Add a section to this track.
Public function Virtual UMovieSceneSection * Generates a new section suitable for use with this track.
Public function Const FGuid  
Public function bool Updates the row indices of sections owned by this track so that all row indices which are used are consecutive with no gaps.
Public function Virtual Const const TArray< UMovieSceneSection * > & Called when all the sections of the track need to be retrieved.
Public function Const const FColor & Get this track's color tint.
Public function Virtual Const ECookOptimizationFlags Called when this track's movie scene is being cooked to determine if/how this track should be cooked.
Public function Virtual Const FText Get the track's display name.
Public function Virtual Const FText Get the track's display tooltip text to be shown on the track's name.
Public function const FMovieSceneTrackEvaluationField & Retrieve a fully up-to-date evaluation field for this track.
Public function Virtual Const int8 Retrieve a version number for the logic implemented in PopulateEvaluationTree.

Public function Virtual Const bool

HasSection ( const UMovieSceneSection& Section
)

 Checks to see if the section is in this track.
Public function Virtual Const bool

IsEmpty ()

  
Public function Const bool  
Public function Const bool

IsRowEvalDisabled ( int32 RowIndex

Protected function Virtual Const bool Called during async load to determine if PostLoad can be called on the loading thread.
Protected function Virtual void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
Protected function Virtual void Do any object-specific cleanup required immediately after loading an object.
