You need to add the listeners to the stage.
You may need to be sure the movieclip listening for the event has focus. If you have some sort of menu or start screen for your game that you click a button on to start, that movieclip can retain focus even if it has been removed from stage.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
