Movieclip having object property

1

Hi all,
I m trying to create 30 movieClip( say enemy) inside a MovieClip (say rect) dynamically.Now enemy can be accessed as rect.enemy meanwhile i need to convert the movieClip enemy into Object so that i can define property like enemy.jump, enemy.inAir.

I have successfully created the 30 enemy but when i tried to trace its any properties like enemies[j].inAir, somewhere else in program, it shows undefined.

var enem:Enemy=new Enemy();
var enemies:Array=new Array();
var killEnem:Object;


function addEnemies() 
    {      
       { for (var i:int=0;i<30;i++)
          { 
            killEnem=new Object();
            killEnem.y=-50;
                killEnem.x=Math.random()*1000;

        if((enem.x<man.mc.x+50)&&(enem.x>man.mc.x-50))
            {   
             rect.addChild(enem);
             killEnem=Object(rect.enem);
             enemies*=killEnem;
            }
        }  
      }
             killEnem.dy = 0.0;
             killEnem.inAir = false;
             killEnem.walkAnimation = new Array(2,3,4,5);
             killEnem.walkSpeed = .08;
             killEnem.width = 10.0;
             killEnem.height = 10.0;
}
