ExpressionTimeline允许您将几个表达式应用到同 一个属性,这样每个表达式都活跃在一定的时期内而不是突变的跳跃。也可以平稳过渡到另一个表达式。此外，您可以指定时间间隔，关键帧运动。可以任意组合多种表达方式。
The ExpressionTimeline allows you to apply several expressions to a property such that each expression is active only for a certain period of time. Instead of an abrupt change between the expressions you can also smoothly transition from one expression to the next. Furthermore, you can specify time intervals in which no expression is active such that the keyframed motion is considered.
