I am using as3 and flash cs6, I have loaded my admob ad in my constructer and then set the ad visibility to false. Then my game is played ( I have added dynamic movieclips etc filling the page ), then on game over i want to show my ad by putting my ad visibitity to true, will my ad still stay above the movieclips or will it be under the movieclips that are on screen as my movieclips were created after the ad ?
