Change Brightness with AS3

programming flash

Hi, I have created a movieclip object, which is added to the stage using a class in a separate *.as file. I am adding multiple instances of the object onto the stage and wish to change the brightness of the objects each time I had one. I have the following code so far:


...
public class RoomClass extends MovieClip
{
  private var rooms:Room;
  private var MAX_RMS:int = 3;
 
  public function RoomClass()
  {
     ...
     for(var i:int=0;i<MAX_RMS;i++)
     {
        rooms = new Room();
        addChild(rooms);
     }
  }
}
...

Can anyone suggest how I may go about changing the brightness of my object.

Thanks in advance
