A set of four conditional statements (if-then statements) are used to detect which arrow key has been pressed, and to move the object five pixels in the direction that the arrow key pressed would indicate.Saltwater Catering Co. In response, the code executes the code in the 'whichKey' function statement. When a key is pressed down, the code in the first line will detect it. Stage.addEventListener(KeyboardEvent.KEY_DOWN, whichKey) function whichKey(event:KeyboardEvent): void Type the code starting at the next line of the ActionScript 3 editor to add an event listener to the Flash stage so that Flash can detect when a key on the keyboard has been pressed, determine if the key pressed is the 'UP,' 'DOWN,' 'LEFT' or 'RIGHT' arrow, and move the object in the appropriate direction (a distance of five pixels) for every press of a arrow key. The 'addChild' method places the object on the stage. The var AS3 code makes a copy of the 'object_One' library symbol and names it 'object_to_move.' Attaching the x and y property to 'object_to_move' in the second and third lines of code positions the symbol. Var object_to_move:object_One = new object_One() object_to_move.x = 400 object_to_move.y = 400 addChild(object_to_move) Click your mouse button, and type in the code below to place a copy of the 'object_One' graphic on the stage and position it at the flash stage coordinates of (400,400): Position your mouse cursor on the first line of the ActionScript 3 editor. Select 'Actions' from the 'Window' menu on the main Flash menu bar to open the ActionScript 3 editor. Click the 'Export for ActionScript' check-box, then 'OK' to assign a class name of 'object_One' for the graphic symbol. Type the name 'object_one' for the symbol in the 'name' text box in the 'Convert to Symbol' dialog box. Select the graphic that you imported and click 'Convert to Symbol' in the 'Modify' menu to convert the graphic to a movie clip object (so the graphic can be animated). Click the 'Import to Library' option in the 'File' menu. Import the graphics object you want to move with the arrows. Click 'Flash File(ActionScript 3.0)' from the splash window to create a new file for the AS3 Flash multiple-drop target project.
