问题描述

我有两个在一个函数中运行的时间线，它们都影响一个对象，问题是当我播放第一个时间线时，另一个时间线也在下一行代码中启动，我如何才能等到第一个时间线完成然后再播放另一个时间线?

I have two timeline which runs inside one function, they are both affect one object, problem is when I play first timeline, other timeline also starts within next line of code, how can I wait until fist timeline finish then play another timeline?

推荐答案

Timeline.play()是异步的—它将在后台启动动画并立即返回.有几种方法可以实现顺序执行.哪个最合适取决于您的用例.

Timeline.play() is asynchronous—it starts the animation in the background and returns immediately. There are several ways to achieve sequential execution. Which fits best depends on your use case.

仅使用一个Timeline，并将KeyFrame从第二个时间轴移至第一个时间轴，并调整开始时间.
第一个时间表完成后，开始第二个时间表:timeline1.setOnFinished(e -> timeline2.play()).
如果可以，请使用Transition而不是Timeline并将它们包装在SequentialTransition中.

Use just one Timeline and move the KeyFrames from your second timeline to the first one, with adjusted start duration.
Start the second timeline when the first one is finished: timeline1.setOnFinished(e -> timeline2.play()).
If you can, use Transitions instead of Timelines and wrap them in a SequentialTransition.
