Functions

Name Description

Public function

AddToken

(
    const TBlendableToken< DataType >&...
)

Conditionally add a token to this stack if it has a >= hierarchical bias, removing anything of a lower bias

Public function Const

void

 

SavePreAnimatedState

(
    IMovieScenePlayer& Player,
    T&&... Args
)

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

Public function Const

void

 

SavePreAnimatedStateForAllEntities

(
    IMovieScenePlayer& Player,
    T&&... Args
)
