caurina缓动类

一、简单的缓动

一个实例名为box的正方体，开始alpha为0.5，在两秒内移动到x:300 y:100的位置，alpha变为1。
import caurina.transitions.Tweener;
Tweener.addTween(box,{x:300, y:100, alpha:1, time:2, transition:"linear"});
使用该类库，使用顺序缓动也很容易，你不需要使用事件同步你的缓动效果

下面代码实现的是在2秒内将一个物体从一个地方改变为x:300 y:100 alpha=1，并在2.5秒后1秒内旋转50°

import caurina.transitions.Tweener;
Tweener.addTween(box,{x:300, y:100, alpha:1, time:2, transition:"linear"});
Tweener.addTween(box,{rotation:50, time:1, transition:"linear",delay:2.5});

例3：下面代码实现的功能为延迟2.5秒后在一秒内旋转50°并在结束时调用函数doThis()

Tweener.addTween(box,{rotation:50, time:1, transition:"linear",delay:2.5, onComplete:doThis});
function doThis()
{
trace("here");
}

例4：下面代码实现的功能为延迟2.5秒后在一秒内旋转50°并在结束时调用函数doThis(s)

Tweener.addTween(box,{rotation:50, time:1, transition:"linear",delay:2.5, onComplete:doThis, onCompleteParams:["hello world"]});
function doThis(s:String)
{
trace(s);
}

例5：下面代码实现的功能为延迟2.5秒后在一秒内旋转50°并在结束时调用函数doThis(n1,n2,n3)

var nr1:Number=1;
var nr2:Number=2;
var nr3:Number=3;
Tweener.addTween(box,{rotation:50, time:1, transition:"linear",delay:2.5, onComplete:doThis, onCompleteParams:[nr1,nr2,nr3]});
function doThis(n1:Number, n2:Number, n3:Number)
{
trace(n1+n2+n3);
} 

例六：下面实例实现五个按钮，依次从大到小显示。

import caurina.transitions.*;
for(var i:uint=0;i<5;i++){
  this["mc"+i]=new mc();
  this["mc"+i].x=i*60+100;
  this["mc"+i].y=180;
  this["mc"+i].width=200;
  this["mc"+i].height=200
  addChild(this["mc"+i])
  this["mc"+i].alpha=0;
  Tweener.addTween(this["mc"+i], { 50,height:50,alpha: 1,y:200, time: 0.2, transition: "easeOutExpo",delay:i*0.2});
}

二、多重缓动

var my_array:Array=new Array();
var timer:Timer;
for(var i:int=0;i<10;i++)
{var clip:MovieClip=new MovieClip();
clip.graphics.beginFill(0x33FFFF,1);
clip.graphics.drawRect(0,0,35,35);
clip.graphics.endFill();
addChild(clip);
my_array.push(clip);
clip.x=35+clip.width*i+10*i;
clip.y=10;
}
timer=new Timer(300,my_array.length);
timer.addEventListener(TimerEvent.TIMER,cambiaColore);
timer.start();
function cambiaColore(evt:TimerEvent):void
{
Tweener.addTween(my_array[evt.target.currentCount-1],{_color:0x333333,time:1,transition:"easeInBounce"});
Tweener.addTween(my_array[evt.target.currentCount-1],{y:100,time:1,transition:"easeInBounce"});
}
