DOTween真的比iTween好很多:
1.编写方面更加人性化
2.效率高很多,其中有一点是因为iTween使用的是unity内置的SendMessage
DOTween一般的样子是这样滴:
using DG.Tweening;
transform.DOMoveX(45, 1).SetDelay(2).SetEase(Ease.OutQuad).OnComplete(MyCallback);
好了,正式开始!
一些名词:
Tweener:补间动画
Sequence:相当于一个Tweener的链表,可以通过执行一个Sequence来执行一串Tweener
Tween:Tweener + Sequence
Nested tween:Sequence中的一个Tweener称为一个Nested tween
主要的方法(就是最常用的):
1.以DO开头的方法:就是补间动画的方法。例如:transform.DOMoveX(100,1)
2.以Set开头的方法:设置补间动画的一些属性。例如:myTween.SetLoops(4, LoopType.Yoyo)
3.以On开头的方法:补间动画的回调方法。例如:myTween.OnStart(myStartFunction)
DOTween初始化与全局设置:
当你第一次创建一个Tween时,DOTween就会自动初始化(只初始化一次),使用缺省值。
当然,也可以使用DOTween.Init方法进行自定义,但要在第一次创建一个Tween前。所有创建的Tween都会受DOTween.Init方法的影响。
但之后,你也可以通过DOTween类的一些静态方法或者变量来修改全局设置:
- static LogBehaviour DOTween.logBehaviour
- static bool DOTween.showUnityEditorReport
- static float DOTween.timeScale
- static bool DOTween.useSafeMode
- static DOTween.SetTweensCapacity(int maxTweeners, int maxSequences)
-
-
- static bool DOTween.defaultAutoKill
- static AutoPlay DOTween.defaultAutoPlay
- static float DOTween.defaultEaseOvershootOrAmplitude
- static float DOTween.defaultEasePeriod
- static Ease DOTween.defaultEaseType
- static LoopType DOTween.defaultLoopType
- static bool DOTween.defaultRecyclable
- static bool DOTween.defaultTimeScaleIndependent
- static UpdateType DOTween.defaultUpdateType
static DOTween.Init(bool recycleAllByDefault = false, bool useSafeMode = true, LogBehaviour logBehaviour = LogBehaviour.ErrorsOnly)
recycleAllByDefault :如果为true,则当Tween完成时就会被回收,放到一个池中;否则就会被destroy
useSafeMode :效率会稍微降低,但更安全
logBehaviour :默认值为只打印错误信息
创建Tweener(有三种方法):
1.
- static DOTween.To(getter, setter, to, float duration)
- 以DOTween.To(() => myVector, x => myVector = x, new Vector3(3, 4, 8), 1);为例,就是对myVector进行插值,目标值为Vector3(3, 4, 8)
2.
- transform.DOMove(new Vector3(2,3,4), 1);
- rigidbody.DOMove(new Vector3(2,3,4), 1);
- material.DOColor(Color.green, 1);
以transform.DOMove(new Vector3(2,3,4), 1)为例,new Vector3(2,3,4)是最终值,意思是用一秒的时间运动到Vector3(2,3,4)
而transform.DOMove(new Vector3(2, 3, 4), 1).From(),就是从Vector3(2,3,4)运动到当前位置
3.
- static DOTween.Punch(getter, setter, Vector3 direction, float duration, int vibrato, float elasticity)
- static DOTween.Shake(getter, setter, float duration, float/Vector3 strength, int vibrato, float randomness, bool ignoreZAxis)
- static DOTween.ToAlpha(getter, setter, float to, float duration)
- static DOTween.ToArray(getter, setter, float to, float duration)
- static DOTween.ToAxis(getter, setter, float to, float duration, AxisConstraint axis)
-
- static DOTween.To(setter, float startValue, float endValue, float duration)
创建Sequence:
Sequence可以包含Sequence,当执行一个Sequence时会顺序执行Tweener,可以使用Insert方法实现同时执行。
Sequence的方法:
- static DOTween.Sequence()
-
- Append(Tween tween)
- AppendCallback(TweenCallback callback)
- AppendInterval(float interval)
- Insert(float atPosition, Tween tween)
- InsertCallback(float atPosition, TweenCallback callback)
- Join(Tween tween)
- Prepend(Tween tween)
- PrependCallback(TweenCallback callback)
- PrependInterval(float interval)
例子:
- // Grab a free Sequence to use
- Sequence mySequence = DOTween.Sequence();
- // Add a movement tween at the beginning
- mySequence.Append(transform.DOMoveX(1, 1));
- // Add a rotation tween as soon as the previous one is finished
- mySequence.Append(transform.DORotate(new Vector3(0, 180, 0), 1));
- // Delay the whole Sequence by 1 second
- mySequence.PrependInterval(1);
- // Insert a scale tween for the whole duration of the Sequence
- mySequence.Insert(0, transform.DOScale(new Vector3(3, 3, 3), mySequence.Duration()));
等同于:
- Sequence mySequence = DOTween.Sequence();
- mySequence.Append(transform.DOMoveX(45, 1))
- .Append(transform.DORotate(new Vector3(0, 180, 0), 1))
- .PrependInterval(1)
- .Insert(0, transform.DOScale(new Vector3(3, 3, 3), mySequence.Duration()));
上面我们提到了全局设置,这里我们再说一说针对Tweener和Sequence的局部设置
- float timeScale
- SetAs(Tween tween \ TweenParams tweenParams)
- SetAutoKill(bool autoKillOnCompletion = true)
- SetEase(Ease easeType \ AnimationCurve animCurve \ EaseFunction customEase)
- SetId(object id)
- SetLoops(int loops, LoopType loopType = LoopType.Restart)
- SetRecyclable(bool recyclable)
- SetUpdate(UpdateType updateType, bool isIndependentUpdate = false)
- 注意的一点是SetUpdate方法可以让目标忽略timeScale
回调方法:
- OnComplete(TweenCallback callback)
- OnKill(TweenCallback callback)
- OnPlay(TweenCallback callback)
- OnPause(TweenCallback callback)
- OnRewind(TweenCallback callback)
- OnStart(TweenCallback callback)
- OnStepComplete(TweenCallback callback)
- OnUpdate(TweenCallback callback)
- OnWaypointChange(TweenCallback<int> callback)
还有一些针对部分Tweener的特殊的局部设置:
注意SetOptions方法必须紧跟Tweener,就好像这样:
DOTween.To(()=> myVector, x=> myVector = x, new Vector3(2,2,2), 1).SetOptions(AxisConstraint.Y, true);
TweenParams:
就是可以将一些参数应用到多个Tweener中
- // Store settings for an infinite looping tween with elastic ease
- TweenParams tParms = new TweenParams().SetLoops(-1).SetEase(Ease.OutElastic);
- // Apply them to a couple of tweens
- transformA.DOMoveX(15, 1).SetAs(tParms);
- transformB.DOMoveY(10, 1).SetAs(tParms);
操作Tweener(有三种方法):
1.DOTween静态方法
- // Pauses all tweens
- DOTween.PauseAll();
- // Pauses all tweens that have "badoom" as an id
- DOTween.Pause("badoom");
- // Pauses all tweens that have someTransform as a target
- DOTween.Pause(someTransform);
2.Tweener方法
myTween.Pause();
3.部件.+以DO开头的方法
transform.DOPause();
- CompleteAll/Complete()
- FlipAll/Flip()
- GotoAll/Goto(float to, bool andPlay = false)
- KillAll/Kill(bool complete = true)
- PauseAll/Pause()
- PlayAll/Play()
- PlayBackwardsAll/PlayBackwards()
- PlayForwardAll/PlayForward()
- RestartAll/Restart(bool includeDelay = true)
- RewindAll/Rewind(bool includeDelay = true)
- TogglePauseAll/TogglePause()
//
