Syntax

USTRUCT ()  
struct FMovieSceneInverseNestedSequenceTransform

Remarks

Structure used to represent a specific inverse transformation (ie from transformed to untransformed space) that cannot be combined with another. Stored as a stack inside FMovieSceneInverseSequenceTransform to represent a complete transformation from inner time-space to outer time-space.

Constructors

  Type Name Description
Public function   Default construction to an identity linear transform. Should only be used by serialization.
Public function   Construction from a linear transform
Public function  

FMovieSceneInverseNestedSequenceTransform ( const FFrameTime& InOffset,
double InTimeScale
)

 Construction from a linear transform represented as an offset and scale (scale is applied first)

Functions

  Type Name Description
Public function Const FMovieSceneTimeTransform Convert this transform to its linear form.
Public function Const FMovieSceneNestedSequenceTransform

Inverse ()

 Convert this transform to its inverse (ie a transform that converts from untransformed space to transformed space)
Public function Const bool Check whether this transform is linear (true) or not (false)
Public function Const bool Check whether this transformation requires a breadcrumb trail (true) or not (false)
Public function Const bool

TransformTimeWithinRange ( FFrameTime Time,
const TFunctionRef< bool(FFrameTime)>& Visitor,
FFrameTime UntransformedRangeStart,
FFrameTime UntransformedRangeEnd
)

 Attempt to transform the specified time by this inverse transform within a specified un-transformed range, calling a functor for every instance of the specified time in the un-transformed space.
Public function Const TOptional< FFrameTime >

TryTransformTime ( FFrameTime Time,
FFrameTime Breadcrumb
)

 Attempt to transform the specified time by this inverse transform.
Public function Const TOptional< FFrameTime >

TryTransformTime ( FFrameTime Time,
FFrameTime Breadcrumb,
const UE::MovieScene::FInverseTransformTimeParams& Params
)

 Attempt to transform the specified time by this inverse transform.
