FMovieSceneNestedSequenceTransform

Structure used to represent a specific transformation (ie from untransformed to transformed space) that cannot be combined with another.

API > API/Runtime > API/Runtime/MovieScene

Structure used to represent a specific transformation (ie from untransformed to transformed space) that cannot be combined with another.

Stored as a stack inside FMovieSceneSequenceTransform to represent a complete transformation from inner time-space to outer time-space.

Functions

Public

Name Remarks Include Path Unreal Specifiers
Convert this transform to its linear form. This is only valid to call where IsLinear() is true Evaluation/MovieSceneSequenceTransform.h  

TRange< FFrameTime > ComputeTraversedHull ( const TRange< FFrameTime >& Range
) const

 Given a range in untransformed space, compute the hull of times that this range encompass when transformed. Evaluation/MovieSceneSequenceTransform.h  

bool ExtractBoundariesWithinRange ( const TRange< FFrameTime >& UntransformedRange,
const TFunctionRef< bool(FFrameTime)>& Visitor
) const

 Extract all the boundaries for this transform within the specified untransformed start and end time, invoking Visitor for every boundary that is present within the range. Evaluation/MovieSceneSequenceTransform.h  
Retrieve this nested transform's time-warp domain, if it has one Evaluation/MovieSceneSequenceTransform.h  
Generate the inverse of this transformation (ie a transform from transformed to untransformed space) Evaluation/MovieSceneSequenceTransform.h

bool IsIdentity()

 Returns whether this transform is an identity transformation (ie, a*T = a) Evaluation/MovieSceneSequenceTransform.h  

bool IsLinear()

 Check whether this transform is linear (true) or not (false) Evaluation/MovieSceneSequenceTransform.h  

bool IsLooping()

   Evaluation/MovieSceneSequenceTransform.h  

bool NeedsBreadcrumb ()

 Check whether this transformation requires a breadcrumb trail (true) or not (false) Evaluation/MovieSceneSequenceTransform.h  

void PostSerialize ( const FArchive& Ar
)

   Evaluation/MovieSceneSequenceTransform.h  
Check whether this transformation supports 'boundaries'. Evaluation/MovieSceneSequenceTransform.h  

void ToString ( TStringBuilderBase< TCHAR >& OutBuilder
) const

 Convert this transformation to a string representation Evaluation/MovieSceneSequenceTransform.h
