javafx animation looping

Question

in c++ or c programming language, we know to change the cordinate we use gotoxy(x,y) and we can use looping and sleep to change the cordinate and making animation. like this

Answer 1

There are three different options in JavaFX, depending on your needs.

The most basic one is AnimationTimer. It's equivalent to Swing's Timer. It simply contains a handle method which is called on every frame, and passed current time as argument. You probably want some internal bookkeeping so that you do not do expensive calculations every time handle is called.

Transition has an interpolate(frac) method, which gets called with values of frac between 0.0 and 1.0. It's up to you to do all UI changes you want to, based on the frac value. Both Transition and Timeline extend Animation, so you can set stuff like cycle duration, whether the Transition is reversed at end, etc.

Timeline is the most complex one. You define arbitrary amount of KeyFrames (think of states) that contain wanted properties of different Nodes, and the Timeline will do all the work for you interpolating how to animate the change between the provided values. For example, you can give a keyframe where x property of a Node is 0, and another where it's 100, and Timeline will do the animating for you.
