Flash TweenLite设计模式

只是好奇。TweenLite/TweenMax是一个非常常见的动画库，我想知道有人会如何对TweenLite中使用的设计模式进行分类。 对于那些不熟悉的人，下面是他们网站上的一些示例代码：

//import the GreenSock classes
import com.greensock.*;
import com.greensock.easing.*;

//tween the MovieClip named "mc" to an alpha of 0.5 over the course of 3 seconds
TweenLite.to(mc, 3, {alpha:0.5});

//scale myButton to 150% (scaleX/scaleY of 1.5) using the Elastic.easeOut ease for 2     seconds
TweenLite.to(myButton, 2, {scaleX:1.5, scaleY:1.5, ease:Elastic.easeOut});

//tween mc3 in FROM 100 pixels above wherever it is now, and an alpha of 0. (notice the vars object defines the starting values instead of the ending values)
TweenLite.from(mc3, 1, {y:"-100", alpha:0});

//after a delay of 3 seconds, tween mc for 5 seconds, sliding it across the screen by changing its "x" property to 300, using the Back.easeOut ease to make it shoot past it and   come back, and then call the onFinishTween() function, passing two parameters: 5 and mc
TweenLite.to(mc, 5, {delay:3, x:300, ease:Back.easeOut, onComplete:onFinishTween,  onCompleteParams:[5, mc]});
function onFinishTween(param1:Number, param2:MovieClip):void {
trace("The tween has finished! param1 = " + param1 + ", and param2 = " + param2);
}

//call myFunction() after 2 seconds, passing 1 parameter: "myParam"
TweenLite.delayedCall(2, myFunction, ["myParam"]);

//use the object-oriented syntax to create a TweenLite instance and store it so we can   reverse, restart, or pause it later.
var myTween:TweenLite = new TweenLite(mc2, 3, {y:200, alpha:0.5, onComplete:myFunction});

//some time later (maybe in by a ROLL_OUT event handler for a button), reverse the tween, causing it to go backwards to its beginning from wherever it is now.
myTween.reverse();

//pause the tween
myTween.pause();

//restart the tween
myTween.restart();

//make the tween jump to exactly its 2-second point
myTween.currentTime = 2;

当它们传递关联数组而不是调用实际函数时，这就是神奇的容器反模式：。这被认为是一个坏主意，因为您应该真正调用特定的函数，而不是构造疯狂的参数包。

而且，TweenLite仍然很受欢迎并被广泛使用。我想这表明，成功的软件并不总是需要以下设计模式。@LarsBlåsjö，是的。。。尽管使用这种模式的一部分目的是试图绕过语言的局限性，所以我不会太多地责怪它们。@LarsBlåsjö，tweenlite是这样设计的，因为flash中的对象是动态的，它不是直接针对displayobjects的，您可以在任何对象上使用tweenlite，并通过若干帧或时间对该对象的任何属性进行插值。事实上，我能看到的唯一的负面影响是保留关键字冲突的可能性可能更高，并且会牺牲一些效率（尽管tweenlite的运行速度比大多数tweening引擎快得多）。我问这个问题是因为我真的很喜欢它的设计！更糟糕的是，TweenLite使用静态方法和函数，并强制您混合使用实例和静态，因为两者都不提供所有功能。
