UMovieGraphDataSourceBase

Movie Graph Pipeline is mostly interested in knowing about ranges of time that it should render, and less concerned with the specifics of where that data comes from (ie: a Level Sequence).

class UMovieGraphDataSourceBase : public UObject

Remarks

Movie Graph Pipeline is mostly interested in knowing about ranges of time that it should render, and less concerned with the specifics of where that data comes from (ie: a Level Sequence). This lets you synchronize with a different data source to provide the ranges of time to render, and then the UMovieGraphTimeStepBase class figures out how to move around within that time step, before calling some functions to synchronize your external data source to actually match the evaluated time.

Functions

  Type Name Description
Public function Virtual void

CacheDataPreJob ( const FMovieGraphInitConfig& InInitConfig
)

 Called when the Movie Graph Pipeline starts before anything has happened, allowing you to cache your datasource before making any modifications to it as a result of rendering.
Public function Virtual void  
Public function Virtual void

ExpandShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot,
const int32 InLeftDeltaFrames,
const int32 InLeftDeltaFramesUserPoV,
const int32 InRightDeltaFrames,
const bool bInPrepass
)

  
Public function Virtual Const FFrameRate A lower res, human readable Frame Rate. We convert to the Tick Resolution internally. (ie: 24/1)
Public function Const UMovieGraphPipeline *  
Public function Virtual Const FFrameRate An internal, high resolution framerate that seeks, etc. will be returned in. (ie: 24,000/1)
Public function Virtual void  
Public function Virtual void

JumpDataSource ( const FFrameTime& InTimeToJumpTo
)

 Called by the Time Step system when the external data source should jump to the given time.
Public function Virtual void  
Public function Virtual void Called by the Time Step system when the external data source should pause playback.
Public function Virtual void Called by the Time Step system when the external data source should start playback (time values will have been set by SyncDataSourceTime
Public function Virtual void  
Public function Virtual void  
Public function Virtual void

SyncDataSourceTime ( const FFrameTime& InTime
)

 Called by the Time Step system when it wants the external data source to update.
