ActionScript 3 - Maze

U all know the game of finding ur way through the maze with pencil right. wll im trying to make a flash game like that with a ball.i have learned how to move the ball and make it collide to walls. but i want to make the ball leave a line on its path where it go. help

You could use the drawing class to add a dot beneath or behind the ball as it moves. Without seeing your code it's hard to know what would work best.
