Here is my code so far, I am trying to create a top down car game and here is the code I have so far, I am currently trying to get the cars to loop but I am struggling to find a way to do it, please try and help me out with the code or point me in the right direction if you can please and thank you in advance
import flashx.textLayout.utils.CharacterUtil;
var result:Number = Math.random() * 100
var randomX:Number = Math.random() * stage.stageWidth
var background = new Background;
var char = new Char();
var car1 = new Car1();
var car2 = new Car2();
var car3 = new Car3();
var car4 = new Car4();
car1.x = Math.random()* stage.stageWidth;
car2.x = Math.random()* stage.stageWidth;
car3.x = Math.random()* stage.stageWidth;
car4.x = Math.random()* stage.stageWidth;
background.x = 200;
char.x = 700/2;
car1.y = -0;
car2.y = -150;
car3.y = -300;
car4.y = -450;

addChild(background);
addChild(char);

}
break;
}
case Keyboard.LEFT:

if (char.hitTestObject(barrier2))
{
char.x +=15 ;
}
break;
}
}
}
stage.addEventListener(Event.ENTER_FRAME, detectCollision);
function detectCollision(event:Event) {

If you're trying to get cars to reposition to the top of the screen as #onekidney guessed, you could easily do so by using the % operator:
function fl_EnterFrameHandler(event:Event):void
{
car1.y = (car1.y + 12) % stage.stageHeight;
car2.y = (car2.y + 12) % stage.stageHeight;
car3.y = (car3.y + 12) % stage.stageHeight;
car4.y = (car4.y + 12) % stage.stageHeight;
}
You can read more about the modulo operator in the documentation

Below is some code for a random particle generator. I want to change it so the particles only move a small distance before stopping and not disappearing. As it is now, they keep moving until they go off stage. I'm new to Actionscript so any help would be appreciated, thanks.
var particleArray:Array = new Array();
var maxParticles:Number = 50000;
function addParticle(e:Event)
{
var Symbol:Symbol3 = new Symbol3();
Symbol.alpha = Math.random() * .8 + .2;
Symbol.scaleX = Symbol.scaleY = Math.random() * .8 + .2;
Symbol.xMovement = Math.random() * 10 - 5;
Symbol.yMovement = Math.random() * 10 - 5;
Symbol.x = mouseX;
Symbol.y = mouseY;
particleArray.push(Symbol);
addChild(Symbol);
Symbol.cacheAsBitmap = true;
if (particleArray.length >= maxParticles)
{
removeChild(particleArray.shift());
}
Symbol.addEventListener(Event.ENTER_FRAME,moveParticle);
}
function moveParticle(e:Event)
{
e.currentTarget.x += e.currentTarget.xMovement;
e.currentTarget.y += e.currentTarget.yMovement;
}
var myTimer:Timer = new Timer(50);
myTimer.addEventListener(TimerEvent.TIMER, addParticle);
myTimer.start();
One way to do this would be to remove the event listener after a number executions:
function addParticle(e:Event)
{
var Symbol:Symbol3 = new Symbol3();
Symbol.alpha = Math.random() * .8 + .2;
Symbol.scaleX = Symbol.scaleY = Math.random() * .8 + .2;
Symbol.xMovement = Math.random() * 10 - 5;
Symbol.yMovement = Math.random() * 10 - 5;
// set the number of times this instance can move.
// Using a randomly generated number here
Symbol.movementCount = int(Math.random() * 10);
Symbol.x = mouseX;
Symbol.y = mouseY;
particleArray.push(Symbol);
addChild(Symbol);
Symbol.cacheAsBitmap = true;
if (particleArray.length >= maxParticles)
{
removeChild(particleArray.shift());
}
Symbol.addEventListener(Event.ENTER_FRAME,moveParticle);
}
function moveParticle(e:Event)
{
e.currentTarget.x += e.currentTarget.xMovement;
e.currentTarget.y += e.currentTarget.yMovement;
// decrement your move count, and then check to see if it's hit zero
e.currentTarget.movementCount--;
if(e.currentTarget.movementCount <=0)
{
// if so, remove the event listener
e.currentTarget.removeEventListener(Event.ENTER_FRAME, moveParticle);
}
}
i'm about to finish my project for University. But I'm stuck with the hittestobject.
var Player: gun = new gun();

}
function moveBullet(e: Event): void
{

}
}

}
else if (mc_target.x > 550)
bullet.removeEventListener(Event.ENTER_FRAME, targeting);

The bullet is going in the Target without any doubt, I see it haha... But won't replace mc_target with mc_burst.

Assuming the code you've posted is everything, the issue is that the targeting method is never called.
Seems like you want to add it as a handler for the enter frame event (as you are removing a listener to that end inside the method)
eg.
bulletInstance.addEventListener(Event.ENTER_FRAME, targeting);
That said, looking at your code, you're going to want to combine your move and targeting functions (you don't want to keep collision checking after you've removed the bullet in your moveBullet function) - or at least remove the targeting enter frame listener when you remove the button from the screen.
Possibly something like this:
function removeBullet(b:MovieClip):void {
b.removeEventListener(Event.ENTER_FRAME, moveBullet);
removeChild(MovieClip(b));
}
function moveBullet(e:Event):void {
var bullet:MovieClip = MovieClip(event.target);
bullet.y -= 12;
bullet.x -= 96;
if(bullet.y <= -200 || bullet.x <= -200 ){
removeBullet(bullet);
}
if (bullet.hitTestObject(mc_target)){
mc_burst.x = mc_target.x;
mc_burst.y = mc_target.y;
mc_burst.gotoAndPlay(2);
mc_target.x = 200;
removeBullet(bullet);
trace("targerting");
} else if (mc_target.x > 550){
removeBullet(bullet);
}
}
If you have many bullets, you'll probably want to have just one enter frame handler, and iterate through each bullet there - instead of having a separate enter frame handler for each bullet.
Also, I'm surprised you are not getting errors, because you have ambiguous naming going on. You have a class called bullet, but then you create vars called bullet as well. Standard practice in AS3 is the give your class names a capitol first letter, and your instance names a lowercase first letter. I'd recommend you do this to avoid errors and ambiguous code.
I would like to thanks BadFeelingAboutThis for his fast help here.

Thanks Guys
Im trying to get this done today so i can move on
Is Baddie a class that is in the default package? If not, you need to import it:
import packagename.Baddie;
If Baddie is a library symbol, make sure you've checked 'Export for ActionScript' and that the linkage name is correct. Also make sure that is is exported in frame 1, or at least before or on the frame that your code is on.
In you Library, right click on Baddie and choose "properties" and check "export for ActionScript". Now you can use Baddie as a class that extends MovieClip.
Sorry, I didn't notice this was already recommended. Basically, your error cannot find a Class named Baddie, hence why you need to specify the custom class through the Library instance.
I am making a shooting game and when i die it will not remove the child's it just freezes them on the screen. I would like to be able to stop all of the action then remove and change screens afterwards.

I've been working on this simple car game in Flash CS5. The car has to avoid the cars coming vertically and pick up coins. I have three types of coins which add 1, 2 and 3 score points on being picked up. My problem is that when I hit the coin with the car it goes through the car and gives much more points. I also have problem with removing it from the stage... Here the code so far:
var spex:Number = 0;
var spey:Number = 4;
var score:uint;
var cars:Array = new Array ;
var db:Number = 2;
var db_coins:Number = 1;
var i:Number = 0;
for (i=0; i<=db; i++)
{
var traffic_mc:MovieClip = new traffic ;
cars.push(addChild(traffic_mc));
cars[i].x = -500 * Math.random();
cars[i].y = Math.random() * 400;
trace(cars[i].y);
}
for (i=0; i<=db_coins; i++)
{
var coin_y:MovieClip = new coin_yellow ;
coin_y.x = -500 * Math.random();
coin_y.y = Math.random() * 400;
addChild(coin_y);
var coin_r:MovieClip = new coin_red ;
coin_y.x = -500 * Math.random();
coin_y.y = Math.random() * 400;
addChild(coin_r);
var coin_b:MovieClip = new coin_blue ;
coin_b.x = -500 * Math.random();
coin_b.y = Math.random() * 400;
addChild(coin_b);
}

i think you should create a variable like hited:Boolean and check first hit. Coin issue occurs cause coin isn't hitting for one time, it is hitting for a while cause every frame you move it and with movement it hits again. So you have to check it and make a proper "if-else" condition.
There is a better solution than the one you decided to use. spex is the variable that you are using to scroll the game. When you run your hitTestObject on the car simply put spex = 0; This will stop the game dead.
I agree with mitim to use removeChild() for the coins instead of just piling them up off stage.
