Though Timeline animation requires more effort on the part of a programmer, it gives more control to manipulate animation effect as well. The intermediate frames are generated by JavaFX with the help of an interpolator. ![]() Timeline animation: In timeline animation, we create the effect by adding key frames to a timeline.There are two types of animation supported by JavaFX, such as: Some of the core animation classes and their hierarchy are as follows. This abstract class provides common properties and methods used by classes that intend to implement animation. JavaFX has a dedicated class, called Animation, representing animation. JavaFX, by default, uses the linear interpolation technique where the key value property of the animated object changes in proportion to the change in the time on the timeline in other words, at (t+5)% time, the value of the property will be (x+5)% between the initial and final target values. The intermediate frames between two consecutive keyframes are generated by the interpolator to produce finer motion otherwise, the animation would look jerky. The key value associated with the keyframe here represents the change of position or translation value along the x-axis. Similarly, at the 5 th second or at key value tx=200 represents the second key frame, and so on. The vehicle at the 0 th second or at key value tx=0 represents the first key frame. The interpolator is responsible for generating intermediate frames.įor example, a vehicle moving left to right horizontally along its x-axis for 20 seconds the time duration is maintained by the horizontal line called the timeline. Every key frame has an associated key value that is modified by the interpolator. Timeline represents the time duration of an animation progression key frame denotes the state of the animated object at a specific instant of time on the timeline. Overview of Java AnimationĪnimation involves a few key concepts such as timeline, key frames, key values, and interpolation. However, all animation does not imply motion for example, if we change the fill property of an object over time, we get an animation of a different sort than motion. If this change of property determines a change in the location coordinate of the object in the screen, we get an illusion of motion. We achieve this in JavaFX by changing the property of a node over time. Animation is computer generated illusory effect implied by the visual change of an object by displaying slightly changed images in quick succession.
