Using Tween class maybe? I tried the easeOut. But if will write 2 Tween, the 2nd one will overwrite the 1st one, so I only see the obj moving in the 2nd Tween direction, not the 1st Tween direction.
I know the coordinates for the 2nd Tween below is not correct (cos all coordinates shld follow the defined reference point), so I need to find out the logo's width and height. But is alright now cos it is for testing purpose.
import fl.transitions.Tween;
import fl.transitions.easing.*;
logo.visible = false;
addChild(logo);
circle.addEventListener(MouseEvent.CLICK, moveObj);
function moveObj(e:MouseEvent):void{
logo.visible = true;
var tweenRight:Tween = new Tween(logo,"x",None.easeOut, 100, 300, 2, true);
var tweenLeft:Tween = new Tween(logo,"x",None.easeOut, 300, 100, 2, true);
}
