Functions

Public

Name Remarks Include Path Unreal Specifiers

void AddToken ( const TBlendableToken< DataType >* TokenToAdd
)

 Conditionally add a token to this stack if it has a >= hierarchical bias, removing anything of a lower bias Evaluation/Blending/BlendableTokenStack.h  

void SavePreAnimatedState ( IMovieScenePlayer& Player,
T&&... Args
) const

 Helper function for saving pre-animated state for all entites that want RestoreState and relate to the current token stack. Evaluation/Blending/BlendableTokenStack.h  

void SavePreAnimatedStateForAllEntities ( IMovieScenePlayer& Player,
T&&... Args
) const

 Helper function for saving pre-animated state for all entites that contributed to this stack, regardless of whether they want restore state or not Evaluation/Blending/BlendableTokenStack.h  

Overridden from IBlendableTokenStack

Name Remarks Include Path Unreal Specifiers

virtual void ComputeAndActuate ( UObject* InObject,
FMovieSceneBlendingAccumulator& Accumulator,
FMovieSceneBlendingActuatorID InActuatorType,
const FMovieSceneContext& Context,
FPersistentEvaluationData& PersistentData,
IMovieScenePlayer& Player
)

 Implemented by typed stacks to compute the final blended value for its data, and apply that result to the specified object Evaluation/Blending/BlendableTokenStack.h  

virtual void Interrogate ( UObject* AnimatedObject,
FMovieSceneInterrogationData& InterrogationData,
FMovieSceneBlendingAccumulator& Accumulator,
FMovieSceneBlendingActuatorID ActuatorTypeID,
const FMovieSceneContext& Context
)

 Implemented by typed stacks to interrogate the final blended value for its data. Evaluation/Blending/BlendableTokenStack.h
