I want my zombie to collect the brains(g1b1,g1b2,g1b3,g1b4). These brains are inside my movieclip 'platform1' because i need it to have a scrolling background effect. Well my zombie character can walk however he can't collect the brains.

Nothing is happening when I press the arrow keys, but neither are there any errors: what's wrong with this? If I remove the key press testing it accelerates accordingly...
At this stage I am just trying to move a block around a screen in an inertial manner using the arrow keys. However, this is my first foray into AS3 so I may be going about it in completely the wrong manner.
Any help would be greatly appreciated.

I am making pong

}
function loop(e:Event) {
movements();
hitTesting();
}
function movements() {
if (changes==true) {
directions = -1;
} else {
directions = 1;
}
x+=speed * directions;
}
function hitTesting() {
/*if (this.hitTestObject(blues)) {
changes = true;
}*/
}
}
}

I am following a tutorial (http://flashdeveloptutorial.blogspot.com/2011/08/chapter-2.html) for AS3 using flash develop to create a pong clone and am having trouble with displaying a main menu. I previously had a functioning prototype with a moving paddle so I believe the error(s) is in my revised(or new) Main, MainMenu, PongGame or CustomEvents file(s). When I run the code as instructed through the tutorial I receive the error ; access of undefined property menu in my Main.as file:
package
{
import flash.display.Sprite;
import flash.events.Event;
/**

* #author
*/
public class Main extends Sprite
{
private var game:PongGame;
****private var menu:MainMenu;****
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
// entry point
}
private function buildMenu():void {
menu = new MainMenu();
addChild(menu);
menu.addEventListener(CustomEvents.LAUNCH_GAME, startGame, false, 0, true);
}
private function startGame(e:CustomEvents):void {
removeChild(menu);
menu.removeEventListener(CustomEvents.LAUNCH_GAME, startGame);
menu = null;
game = new PongGame();
addChild(game);
}
}
}
So I added the "private var menu:MainMenu;" section but I do not know what class/ .as file to reference? or how to define var menu:
Sorry for the large amount of attached code. I did not change paddle.as which is the longest file.

I'm not sure where to go from here to fix this error. Any help would be appreciated.
Although you've correctly added the menu property, the menu is never displayed because buildMenu() function is never called.
From your main class init(), call buildMenu() to instantiate and add menu to the stage:
Main.as
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
// entry point
buildMenu();
}
I am writing a program in AS3. It's exact contents don't seem to matter here. I basically have 4 classes, split in 4 files. Thing is, it can't find one of these files, and I can't understand why. I have checked it several times and even had my teacher check it, and we still can't find what is wrong with it. Did anyone else have a similar problem, or have any idea on how to solve this problem?

Check this line in the second file:

I think your getting 2 errors as this function is triggered twice within script or some related change it and let us know.
