i want create road parallax scrolling down with flash in as3, when i run the script, the parallax moving up. and this my code
package {
import flash.display.MovieClip;
import flash.events.Event;
public class kelas extends MovieClip{
this i create variable
public var road:road1;
public var road2:road1;
public var roadContainer:MovieClip;
public var roadBreadth:Number;
public var car:Car;
public function kelas(){
and this create car , road and container
car = new Car();
road = new road1();
road2 = new road1();
roadBreadth = 653.7;
car.y = 10.0;
car.x = 10;
road.y = 10.0;
road.x = 10;
road2.y = road.y + roadBreadth;
road2.x = road.x;
//* add child object
roadContainer = new MovieClip();
roadContainer.addChild(road);
roadContainer.addChild(road2);
this.addChild(roadContainer);
this.addEventListener(Event.ENTER_FRAME, onEnterFrame);
public function onEnterFrame(event:Event):void
{
car.y = car.y + 15;
roadContainer.y = 10 - car.y + 10;
if (road.y + roadBreadth + roadContainer.y < 0)
{
road.y = road.y + (2 * roadBreadth);
}
if (road2.y + roadBreadth + roadContainer.y < 0)
{
road2.y = road2.y + (2 * roadBreadth);
}
}
}
i want this backgroung moving down is not moving up, please help me
Have a look at this sample, it's a pretty simple idea to wrap an object around. Make sure your multiplier is set to the amount of roads that you're wrapping.
if (road.y > 600) {
road.y -= road.y * 2;
} else {
road.y++;
}
may be your roadContainer contains road, so when you move roadContainer, you moves road too.
so, just move don't let it contains, add when you move the background.y++, road will like moving up

I’m trying to make a simple game that uses a basic equation:
‘linkCount’ / ‘clickCount’ * 100 to create a % success amount, ‘percentCount’
The text fields and the following as3 all live in a Movieclip on root level with instance name ‘counter_int’:
as3:
var clickCount:int = 1; //see below* for what controls this number
var linkCount:int = 1; //see below* for what controls this number
var percentCount:int = (100);
percentCount++;
percent_text.text = (int(linkCount) / int(clickCount) * 100 + "%").toString();
This works fine and displays a % amount in the correct field. However, my question is about truncating the % I get to remove anything after the decimal place. I’ve tried everything I can to get this to work but it’s not having it.
*
Now, here’s the tricky bit that i think is possibly causing my Math.round problem… I basically just don’t know where or how to apply the Math.round instruction?! I also suspect it might be a problem with using ‘int’ and have tried using ‘Number’ but it still displays decimal places.
I am using 2 buttons within 25 different movieclips…
Button locations:
all_int_circles_master.cone.FAILlinkbutton
all_int_circles_master.cone.linkbutton
all_int_circles_master.ctwo.FAILlinkbutton
all_int_circles_master.ctwo.linkbutton
etc … to ctwentyfive
The as3 on FAIL buttons:
FAILlinkbutton.addEventListener(MouseEvent.CLICK, addClick1);
function addClick1(event:MouseEvent):void
{
Object(root).counter_int.clickCount++;
Object(this.parent.parent).counter_int.clicked_total.text = Object(root).counter_int.clickCount.toString();
}
The as3 on successful link buttons:
linkbutton.addEventListener(MouseEvent.CLICK, onClickNextSlide2);
function onClickNextSlide2(event:MouseEvent):void
{
Object(root).counter_int.clickCount++;
Object(this.parent.parent).counter_int.clicked_total.text = Object(root).counter_int.clickCount.toString();
}
The % currently gets returned as e.g.:
74.334753434
but I need it to just be:
74
Any help would be greatly appreciated. I can supply the .fla if necessary. This is kind of what I've been trying but no luck so far:
should the Math.round be applied at root level / globally somehow!?
should the Math.round be applied within the counter_int movieclip?
should the Math.round be applied within all of the all_int_circles_master.cone / two / three... movieclips?
Thanks
Have you tried
percent_text.text = (Math.round(int(linkCount) / int(clickCount) * 100) + "%").toString();
percent_text.text = (int(linkCount) / int(clickCount) * 100 +
"%").toString();
I think you have your clickCount and linkCount backwards, swap those and round the results before adding the percent symbol:
percent_text.text = (Math.round((int(clickCount) / int(linkCount) * 100)).toString() + "%";
A pure AS3 example:
package {
import flash.display.Sprite;
import flash.text.TextField;
import flash.events.MouseEvent;
public class Main extends Sprite {
var clickCount:int = 0;
var linkCount:int = 30;
var clicked_total:TextField;
var button:CustomSimpleButton;
public function Main() {
button = new CustomSimpleButton();
button.addEventListener(MouseEvent.CLICK, onClickNextSlide2);
addChild(button);
clicked_total = new TextField();
clicked_total.text = "0%";
clicked_total.x = 100;
addChild(clicked_total);
}
function onClickNextSlide2(event:MouseEvent):void {
clickCount++;
if (clickCount < linkCount) {
clicked_total.text = (Math.round((clickCount / linkCount) * 100)).toString() + "%";
} else {
clicked_total.text = "Done";
}
}
}
}
import flash.display.Shape;
import flash.display.SimpleButton;

private var upColor:uint = 0xFFCC00;

useHandCursor = true;
}

I used a creative cow tutorial to create my own snow globe that moves and snow reactivates - it really is a great tutorial.
What I'm trying to do is Change between 3 Movie clips in the ActionScript - But each time I add my movie clip names - Or try and add a simple visibility code I break my snow globe actions.
I have my MovieClip instances named friendsSceneThree, BuddiesSceneTwo and HatsOffSceneOne. I would think they'd be good but somewhere I'm missing something. Right now I can't get the code to even SEE The movieclips I'm getting a simple:
TypeError: Error #1006: value is not a function.at SnowGlobeContainer/update()
Down in the 'if drag' Update is where I'd like to Change from One MClip to the Next.
What Am I Not Seeing?!?! Any help would be greatly appreciated! Thanks

I appreciate the help -- If you haven't noticed I'm new to all of this scripting. I'm looking in on lynda.com and other forums. the SnowGeneratorCircle.as is:
package {
import flash.display.Sprite;
import flash.events.Event;
public class SnowGeneratorCircle extends Sprite {
var totalFlakes:int = 500;
var flakes:Array = new Array();
public function SnowGeneratorCircle() {
addSnowFlakes();
addEventListener(Event.ENTER_FRAME, update);
}
protected function addSnowFlakes():void{
for(var i:int=0; i<totalFlakes; i++){
var f:SnowFlake = new SnowFlake();
addChild(f);
flakes.push(f);
}
}
public function reset():void{
for(var i:int=0; i<totalFlakes; i++){
var f:SnowFlake = flakes[i];
f.reset();
}
}
public function update(e:Event=null):void {
for(var i:int=0; i<totalFlakes; i++){
var f:SnowFlake = flakes[i];
f.update(0);
}
}
}
}
I debugged - didn't clean up the code, because every time I did - it broke the actions. So I left the code with the double spacing. That's how it went in when I copied and pasted from the tutorial anyway.
Here's the error on line 173 - which is the MovieClip I'd like to have change.

I just don't know how to get the actionscript to find my MovieClips and then swap them out wt each shake of the globe.
Sorry for the vague question. The point is I would like to run an external actionscript(.as) file at a specify frame so that it won't run unless I clicked start button from the main menu. This is to make sure the game sprites won't appear on the main menu. I have tried "Export classes in frame" option but it won't work. The actionscript is already set to document class. I have no code placed on timeline.

The external code you posted is a class. That means the code in it will not run before you create an instance of it. Move the instance creation to the frame where you wish the code to be executed and you should be getting the behaviour you asked for.
If you don't know what an instance is, look for a line that contains something like:
...=new match_it();
addChild(...);
Those 2 lines create an instance of the match_it class and add it to the display hierachy. Move them to the frame in question. There might be more code that is required to be moved, but since you didn't paste the actual instantiation, that's something that I can't really tell.
I also would suggest taking a look at the basics of as3 classes, it will make your life a lot easier, here's an tutorial:

Hello im with a doubt and need your help if its possible.
I have a class dish and i load 1 file ".swf", and i have a little game that works like this:
The dish moves in the x and y axis and i when i click in the dish it falls down.
But i want to have not only 1 dish i want have 10 different dishes with diferent images.
And i want that they appear in a random sequence.
But i dont have ideia how i cant do that...someone can give me "light"?
I use this variables to load my dish to the stage in my game project.
var load_dish:Loader = new Loader();
var path:URLRequest = new URLRequest("dish.swf");
Here's an example of what you could do to get a random dish each time :
// whenever you need to create a new dish
var dishFilenames:Array = ['dish1.swf', 'dish2.swf', 'dish3.swf']; // etc etc
var randomIndex:int = Math.random() * dishFilenames.length;
var filename:String = dishFilenames[randomIndex];
var load_dish:Loader = new Loader();
var path:URLRequest = new URLRequest(filename);
thank for the answer!
so i cant have all the dishes in the same "swf"?
I need to create swf as many as i need?
My class dish is like this until now:
I dont have other way to do that?(with only a swf that contains all the dishes)
package {
import flash.events.Event;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.MouseEvent;
public class Dishe {
var velX: int;
var velY: int ;
var game:Game; //i have also a class game to control everyting
var broken_dish:URLRequest = new URLRequest("broken_dish.swf");
var gravity:int = 2;
var dishFilenames:Array = [ 'dish.swf','second_dish.swf'];
var randomIndex:int = Math.random() * dishFilenames.length;
var filename:String = dishFilenames[randomIndex];
var load_dish:Loader = new Loader();
var path:URLRequest = new URLRequest(filename);
public function Dishe(e:Game, vX:int, vY:int)
{
velX = vX;
velY = vY;
load_dish.x = -180;
load_dish.y = randomBetween(250,-5);
load_dish.load(caminho);
game = e;
game.myStage.addChild(load_dishe);
load_dish.addEventListener(MouseEvent.CLICK, _shoot);
}
public function broken_dish(e:Event)
{
velY += gravity;
load_dish.y +=velY ;
if(load_dish.y >= game.myStage.stageHeight)
{
game.game_states(Game.state_playing);
}
}
public function _enterFrame(e:Event):void
{
if(load_dish.content!=null)
{
load_dish.x += velX;
load_dish.y += velY *(1 - (load_dish.x / game.myStage.stageWidth) * 2 );
if(load_dish.x > game.myStage.stageWidth)
{
load_dish.y = randomBetween(250,-5);
load_dish.x = -180;
}
}
}
public function _shoot(e:MouseEvent):void
{
trace("nice!!");
game.game_states(Game.state_stop);

This question is related to ActionScript 3.0 and Flash CS6
I am trying to make an object shake a bit in a certain for some seconds. I made it a "movieclip" and made this code:
import flash.events.TimerEvent;
var Machine_mc:Array = new Array();
var fl_machineshaking:Timer = new Timer(1000, 10);
fl_machineshaking.addEventListener (TimerEvent.TIMER, fl_shakemachine);
fl_machineshaking.start ();
function fl_shakemachine (event:TimerEvent):void {
for (var i = 0; i < 20; i++) {
Machine.x += Math.random() * 6 - 4;
Machine.y += Math.random() * 6 - 4;
}
}
When testing the movie I get multiple errors looking exactly like this one:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Historieoppgave_fla::MainTimeline/fl_shakemachine()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
Also, the object doesnt shake, but it moves steadily upwards to the left a bit every tick.
To the point:
I wish to know how I stop the script after the object is not in the stage/scene anymore and also how to make it shake around, as I do not see what is wrong with my script, please help, thank you ^_^
AStupidNube brought up a great point about the original position. So adding that to shaking that should be a back and forth motion, so don't rely on random values that may or may not get you what you want. Shaking also has a dampening effect over time, so try something like this:
Link to working code
• http://wonderfl.net/c/eB1E - Event.ENTER_FRAME based
• http://wonderfl.net/c/hJJl - Timer Based
• http://wonderfl.net/c/chYC - Event.ENTER_FRAME based with extra randomness
**1 to 20 shaking items Timer Based code - see link above for ENTER_FRAME code••

}
Now this is a linear dampening, you can adjust as you see fit by squaring or cubing the values.
You have to remember the original start position and calculate the shake effect from that point. This is my shake effect for MovieClips. It dynamically adds 3 variables (startPosition, shakeTime, maxShakeAmount) to it. If you use classes, you would add them to your clips.
import flash.display.MovieClip;
import flash.geom.Point;
function shake(mc:MovieClip, frames:int = 10, maxShakeAmount:int = 30) : void
{
if (!mc._shakeTime || mc._shakeTime <= 0)
{
mc.startPosition = new Point(mc.x, mc.y);
mc._shakeTime = frames;
mc._maxShakeAmount = maxShakeAmount;
mc.addEventListener(Event.ENTER_FRAME, handleShakeEnterFrame);
}
else
{
mc.startPosition = new Point(mc.x, mc.y);
mc._shakeTime += frames;
mc._maxShakeAmount = maxShakeAmount;
}
}
function handleShakeEnterFrame(event:Event):void
{
var mc:MovieClip = MovieClip(event.currentTarget);
var shakeAmount:Number = Math.min(mc._maxShakeAmount, mc._shakeTime);
mc.x = mc.startPosition.x + (-shakeAmount / 2 + Math.random() * shakeAmount);
mc.y = mc.startPosition.y + (-shakeAmount / 2 + Math.random() * shakeAmount);
mc._shakeTime--;
if (mc._shakeTime <= 0)
{
mc._shakeTime = 0;
mc.removeEventListener(Event.ENTER_FRAME, handleShakeEnterFrame);
}

You can use it like this:
// shake for 100 frames, with max distance of 15px
this.shake(myMc, 100, 15);
BTW: In Flash, you should enable 'permit debugging' in your 'publish settings' to have more detailed errors. This also gives back the line numbers where your code is breaking.
update:
Code now with time / maximum distance separated.
Here is a forked version of the chosen answer, but is a bit more flexible in that it allows you to set the frequency as well. It's also based on time as opposed to frames so you can think in terms of time(ms) as opposed to frames when setting the duration and interval.
The usage is similar to the chosen answer :
shake (clipToShake, durationInMilliseconds, frequencyInMilliseconds, maxShakeRange);
This is just an example of what I meant by using a TimerEvent as opposed to a ENTER_FRAME. It also doesn't require adding dynamic variables to the MovieClips you are shaking to track time, shakeAmount, and starting position.
public function shake(shakeClip:MovieClip, duration:Number = 3000, frequency:Number = 30, distance:Number = 30):void
{
var shakes:int = duration / frequency;
var shakeTimer:Timer = new Timer(frequency, shakes);
var startX:Number = shakeClip.x;
var startY:Number = shakeClip.y;
var shakeUpdate:Function = function(e:TimerEvent):void
{
shakeClip.x = startX + ( -distance / 2 + Math.random() * distance);
shakeClip.y = startY + ( -distance / 2 + Math.random() * distance);
}
var shakeComplete:Function = function(e:TimerEvent):void
{
shakeClip.x = startX;
shakeClip.y = startY;
e.target.removeEventListener(TimerEvent.TIMER, shakeUpdate);
e.target.removeEventListener(TimerEvent.TIMER_COMPLETE, shakeComplete);
}
shakeTimer.addEventListener(TimerEvent.TIMER, shakeUpdate);
shakeTimer.addEventListener(TimerEvent.TIMER_COMPLETE, shakeComplete);
shakeTimer.start();
}
-4 <= Math.random() * 6 - 4 < 2
You add this offset to Machine.x 20 times, so chances for moving to the left is greater, than to the right.
It seems that you looking for something like this:
for each (var currentMachine:MovieClip in Machine_mc)
{
currentMachine.x += Math.random() * 6 - 3;
currentMachine.y += Math.random() * 6 - 3;
}
