Answer 2

//帮你修改了一下，可以直接使用，达到你想要的结果,如果没达到你效果，请详细说明一下
import fl.transitions.Tween;
import fl.transitions.easing.*;
import flash.display.MovieClip;
import flash.events.MouseEvent;

var instrument:MovieClip
var speed:Number=2//移动速度自己调
var ImgNum:int=6;//你目前图片是6张
var stageWidth:Number=stage.stageWidth
var comeback:Boolean=false
var moveBoolean:Boolean

addListener()

function addListener(){
for(var i:int=1;i<=ImgNum;i++){
var mc:MovieClip=getChildByName("mc"+String(i)) as MovieClip
mc.addEventListener(MouseEvent.CLICK,onmc);
}

btn.addEventListener(MouseEvent.CLICK,MouseHandler)//btn为你按钮的实例名称
}
function MouseHandler(e:MouseEvent):void{
if(!moveBoolean) startMove()
if(moveBoolean) stopMove()
moveBoolean=!moveBoolean
}

function onmc(e:MouseEvent):void {
instrument = e.currentTarget as MovieClip
if(!comeback){

new Tween(instrument, "scaleX", Elastic.easeOut, .2, 2, 3, true);
new Tween(instrument, "scaleY", Elastic.easeOut, .2, 2, 3, true);
}else{

new Tween(instrument, "scaleX", Elastic.easeOut, 2.2, 1, 3, true);
new Tween(instrument, "scaleY", Elastic.easeOut, 2.2, 1, 3, true);
}
comeback=!comeback

}

function EventHandler(e:Event){
for(var i:int=1;i<=ImgNum;i++){
var mc:MovieClip=getChildByName("mc"+String(i)) as MovieClip
Move(mc)
}
}

function Move(mc:MovieClip):void{
mc.x+=speed
if(mc.x>stageWidth) mc.x=-mc.width
}

function startMove():void{
addEventListener(Event.ENTER_FRAME,EventHandler)
}
function stopMove():void{
removeEventListener(Event.ENTER_FRAME,EventHandler)
}
