The Universal Tween Engine enables the interpolation of every attribute from any object in any Java project (being Swing, SWT, OpenGL or even Console-based). Implement the TweenAccessor interface, register it to the engine, and animate anything you want!
In one line, send your objects to another position (here x=20 and y=30), with a smooth elastic transition, during 1 second).
// Arguments are (1) the target, (2) the type of interpolation, // and (3) the duration in seconds. Additional methods specify // the target values, and the easing function. Tween.to(mySprite, Type.POSITION_XY, 1.0f).target(20, 30).ease(Elastic.INOUT); // Possibilities are: Tween.to(...); // interpolates from the current values to the targets Tween.from(...); // interpolates from the given values to the current ones Tween.set(...); // apply the target values without animation (useful with a delay) Tween.call(...); // calls a method (useful with a delay) // Current options are: myTween.delay(0.5f); myTween.repeat(2, 0.5f); myTween.repeatYoyo(2, 0.5f); myTween.pause(); myTween.resume(); myTween.setCallback(callback); myTween.setCallbackTriggers(flags); myTween.setUserData(obj); // You can of course chain everything: Tween.to(...).delay(1.0f).repeat(2, 0.5f).start(myManager); // Moreover, slow-motion, fast-motion and reverse play is easy, // you just need to change the speed of the update: myManager.update(delta * speed);
Create some powerful animation sequences!
Timeline.createSequence() // First, set all objects to their initial positions .push(Tween.set(...)) .push(Tween.set(...)) .push(Tween.set(...)) // Wait 1s .pushPause(1.0f) // Move the objects around, one after the other .push(Tween.to(...)) .push(Tween.to(...)) .push(Tween.to(...)) // Then, move the objects around at the same time .beginParallel() .push(Tween.to(...)) .push(Tween.to(...)) .push(Tween.to(...)) .end() // And repeat the whole sequence 2 times // with a 0.5s pause between each iteration .repeatYoyo(2, 0.5f) // Let's go! .start(myManager);
