Functions

Name Description

Public function

void

 

Apply

(
    const FMovieSceneContext& Context,
    FPersistentEvaluationData& Persist...,
    IMovieScenePlayer& Player
)

Apply all currently accumulated blends

Public function

void

 

BlendToken

(
    FMovieSceneBlendingActuatorID InAct...,
    const FMovieSceneEvaluationScope& ...,
    const FMovieSceneContext& InContex...,
    TBlendableToken< ActuatorDataType >...
)

Add a global token (not bound to a particular object) that will be blended together with other tokens of the same type and actuator this frame Such tokens are collated actuator, meaning the same data type can be blended in the same manner but applied differently depending on context (ie, multiple floats that relate to slomo and fade tracks)

Public function

void

 

BlendToken

(
    const FMovieSceneEvaluationOperand ...,
    FMovieSceneBlendingActuatorID InAct...,
    const FMovieSceneEvaluationScope& ...,
    const FMovieSceneContext& InContex...,
    TBlendableToken< ActuatorDataType >...
)

Add a token that will be blended together with other tokens of the same type and actuator this frame, and applied to all objects relating to the specified operand Such tokens are collated per-object and actuator, meaning the same data type can be blended in the same manner, but applied differently depending on context (ie, multiple float properties on the same object)

Public function

void

    FMovieSceneInterrogationData& Inte...,
    UObject* AnimatedObject
)

Interrogate the final blended result when applied to the specified object
