TweenAccessor设置初始值和目标值的接口
Tween：在初始值和目标值之间做动画补充
OriginalTween：动画的帧计算类
BaseTween：一个抽象类，有一个类似Activity的生命过程：开始-暂停-结束。
Timeline：一个实现BaseTween抽象类的类。这个类可以实现多个多个对象的连续动画。
1 public class ActorListener implements ApplicationListener{ 2 private Stage mStage; 3 private Texture texture; 4 private ActorView mActorView; 5 public ActorListener() { 6 7 } 8 @Override 9 public void create() { 10 mStage =new Stage(240, 400, true); 11 //早View中画一张图片 12 mActorView =new ActorView("image"); 13 texture =new Texture(Gdx.files.internal("flower.jpg")); 14 mActorView.region =new TextureRegion(texture,0,0,64,64); 15 mActorView.setSize(64, 64); 16 mStage.addActor(mActorView); 17 //将ActorView.class这个对象的处理类ActorAccessor的对象Push到Map中 18 Tween.registerAccessor(ActorView.class, new ActorAccessor()); 19 //设置动画需要变换的值，有X，Y坐标，颜色等 20 Tween.to(mActorView, ActorAccessor.POS_XY, 1.0f) 21 //设置动画效果 22 .ease(Bounce.INOUT) 23 //设置坐标的目标值 24 .target(200, 300) 25 //把这个动画放到tweenManager中,真正启动动画是在render中 26 .start(ActorAccessor.tweenManager); 27 } 28 @Override 29 public void render() { 30 Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); 31 ActorAccessor.tweenManager.update(Gdx.graphics.getRawDeltaTime()); 32 mStage.act(Gdx.graphics.getDeltaTime()); 33 mStage.draw(); 34 35 } 36 }
Timeline 实现多个连续的动画。
//同一个对象在不同的时间段内实现一组连续的动画。
Timeline.createSequence();
下面这段代码实现分别在每秒中移动到某个坐标
1 public class ActorListener implements ApplicationListener{ 2 private Stage mStage; 3 private Texture texture; 4 private ActorView mActorView; 5 private Timeline mTimeline; 6 public ActorListener() { 7 8 } 9 @Override 10 public void create() { 11 mStage =new Stage(240, 400, true); 12 mActorView =new ActorView("image"); 13 texture =new Texture(Gdx.files.internal("flower.jpg")); 14 mActorView.region =new TextureRegion(texture,0,0,64,64); 15 mActorView.setSize(64, 64); 16 mStage.addActor(mActorView); 17 Tween.registerAccessor(ActorView.class, new ActorAccessor()); 18 //创建一个Timeline对象，这个对象是一个动画的集合 19 mTimeline = Timeline.createSequence(); 20 21 mTimeline.push(Tween.to(mActorView, ActorAccessor.POS_XY, 1.0f).target(200, 300, 0).ease(Bounce.INOUT)); 22 mTimeline.push(Tween.to(mActorView, ActorAccessor.POS_XY, 1.0f).target(100, 200, 0).ease(Bounce.INOUT)); 23 mTimeline.push(Tween.to(mActorView, ActorAccessor.POS_XY, 1.0f).target(20, 30, 0).ease(Bounce.OUT)) .start(ActorAccessor.tweenManager); 24 25 } 26 @Override 27 public void render() { 28 Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); 29 //开始更新动画 30 ActorAccessor.tweenManager.update(Gdx.graphics.getRawDeltaTime()); 31 mStage.act(Gdx.graphics.getDeltaTime()); 32 mStage.draw(); 33 34 } 35 }
//在相同的时间段内实现各种动画，比如一边移动一边旋转一边放大缩小
Timeline.createParallel();
下面这段代码实现在同一秒内，在移动的过程中不断的缩小图片
