Ok so i have some variables called "stat" that is inside a movie clip that i need to access from the main timeline. I have tried multiple ways but none of them have worked.
Edited.
I put the stage instance Movieclip names "mc". and this is have a this script.
var stat:String ="Test";
and next following script, Main timeline. If you access mc.stat you not get value. console show to null. when you called In Main timeline script access to instance MovieClip inner variable. because maybe Initialization code inside the script does not work yet. so you should delay called.
I suggested Using the Timer. try this:
import flash.events.Event;
import flash.utils.Timer;
import flash.events.TimerEvent;
trace("check1:" + mc.stat);
var timer:Timer = new Timer(1, 1);
timer.addEventListener(TimerEvent.TIMER, onAdded);
timer.start();
function onAdded(e:TimerEvent):void
{
timer.removeEventListener(TimerEvent.TIMER, onAdded);
trace("check2:" + mc.stat);
}
Code is always helpfull!
The movieclip musst exist at the time the code is executed.
trace("stat value in mc = " + mcName.stat);

New to AS3. Trying to do a simple mask exercise, but for some reason when I add event listener to 'myMask', the event doesn't trigger. I tried turning both 'myMask' and 'theMaskee' as sprites and movie clips, but no luck. It does trigger if I don't assign 'myMask' as a mask to 'theMaskee'. It also works if I add the listener directly to the stage, but eventually I want to put many things on the stage, and I'm afraid there will be conflict if it has to listen to the same event but perform several functions... especially if I need them one at a time. I looked through textbooks and the API and mask-related questions other people had, but I can't find anything relating to my specific situation.
(this code is written directly in the timeline)
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.sampler.NewObjectSample;
import flash.events.MouseEvent;
var temp = new backGround();
var myBG:Bitmap = new Bitmap(temp);
temp = new splashMaskee();
var theMaskee:Bitmap = new Bitmap(temp);
var myMask = new MovieClip();
myMask.graphics.beginFill(0x000000, 0);
myMask.graphics.drawRect(0, 0, 800, 600);
myMask.graphics.endFill();
myMask.cacheAsBitmap = true;
theMaskee.cacheAsBitmap = true;
theMaskee.mask = myMask;
addChild(myBG);
addChild(theMaskee);
addChild(myMask);
myMask.addEventListener(MouseEvent.CLICK, myMaskClick);
//stage.addEventListener(MouseEvent.CLICK, myMaskClick);
function myMaskClick(e:MouseEvent):void
{
trace("click");
myMask.graphics.beginFill(0x000000, 1);
myMask.graphics.drawCircle(mouseX, mouseY, 30);
}
Thank you for taking the time
You need to add the listener to theMaskee instead, not your mask.
The mask in AS3 does not implement IEventDispatcher therefore can not catch and dispatch events.
Do this:
theMaskee.addEventListener(MouseEvent.CLICK, myMaskClick);
And it should work. :)
Masks dont take any mouse/keyboard events as it is just a mask and not actually present in the display list.
i have got a problem and cannot figure out. Everything is fine when i test the scene, i have added stop(); to my movie clip timeline and everything is fine until no code is added to the main stage. As soon as i start adding code to the stage, it starts looping? Because of this i'm stuck with a problem and cannot even develop further, because even mouse click events wont work of that looping... The code i am trying to add is just a simple move layer off stage after click on play button:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
introScreen.play_btn.addEventListener(MouseEvent.CLICK, clickAway);
function clickAway(event:MouseEvent):void
{
moveScreenOff(introScreen);
}
function moveScreenOff(screen:MovieClip):void
{
//Move the screen off...
var introTween = new Tween(screen,"x",Strong.easeInOut,screen.x,(screen.width)*-1,1,true);
//When the motion has finished...
introTween.addEventListener(TweenEvent.MOTION_FINISH, tweenFinish);
function tweenFinish(e:TweenEvent):void
{
trace("tweenFinish");
//Establish the game state...
gameState = STATE_INIT_GAME;
trace(gameState);
//Fire off the gameLoop function at the frame rate of the movie...
addEventListener(Event.ENTER_FRAME, gameLoop);
}
}
The reason your animations are looping continuously is because you have errors in your code.
Access of undefined property gameState.
Access of undefined property STATE_INIT_GAME.
Access of undefined property gameState.
Access of undefined property gameLoop.
You are trying to reference members that haven't been created yet or don't exist. Your main timeline starts at frame 1 with the code you referenced trying to access those variables and the gameLoop method. You need to setup the variables in the first frame to allow them to be referenced. i.e. under your import statements:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var gameState:String;
const STATE_INIT_GAME:String = "GAME_INIT";
then you need to add the gameLoop function:
function gameLoop(e:Event):void {
trace('game loop running');
}
If you don't want those variables and that function setup there then you need to go to the frame using gotoAndStop or gotoAndPlay where those functions and variables can be declared and/or initialized, and stored into memory. Then they will be accessible.
I am at the moment trying to create an interactive movie, structured so that each keyframe in the timeline contains a movieclip navigated to using buttons inside the movieclips, with the appropriate code inside the main timeline.
The problem right now is that when you access the movieclip inside frame 3, the sound from frame 2 also plays simultaneously. After doing some research i found that this appears to be a bug with flash itself, and most of the time is dealt with using SoundMixer.stopAll();. Sadly, i have no idea how to use it to kill the sound from frame 2 when only frame 3 is accessed.
I know that when accessing frame 2 instead, only frame 2 is played, which should mean that flash basically goes through all frames on the way to the frame you are supposed to go to.
This is the limited code i am using at the moment:
Frame 1:
import flash.events.MouseEvent;
import flash.display.SimpleButton;
import flash.media.SoundMixer;
stop();
var soundVar:int = 0;
var Choice1F:SimpleButton;
var Choice1R:SimpleButton;
this.Val1.Choice1F.addEventListener(MouseEvent.CLICK, function(me:MouseEvent):void{buttonHandler(me, 2)});
this.Val1.Choice1R.addEventListener(MouseEvent.CLICK, function(me:MouseEvent):void{buttonHandler(me, 3)});
function buttonHandler(e:MouseEvent, Value:int): void{
SoundMixer.stopAll();
soundVar = Value;
this.gotoAndPlay(Value);
}
Frame 2:
import flash.media.SoundMixer;
stop();
if(soundVar == 3){
SoundMixer.stopAll();
}
Frame 3 simply contains a stop(); statement. The code in frame 2 was a futile attempt from me to make it kill the sound on its way to frame 3. Hopefully, you guys can think of a better solution, if one even exists.
The correct structure of the project assumes that you control the playback of music and sounds with a special instance of custom class. And timeline you use only gave him command when and what to do.
One SoundChannel and couple of Sound's will do the trick.
You could use this one
package src.utils{
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;
public dynamic class BackgroundMusicPlayer extends Object{
public var playlist;
public var sndChannel;
private var ID;
public function BackgroundMusicPlayer(srcList:Array){
playlist=[];
for(var i=0;i<srcList.length;i++){
var src= new URLRequest(srcList[i]);
var newSound = new Sound(src);
playlist.push(newSound);
}
}
public function playMusic(id){
if (sndChannel!=undefined) {
sndChannel.stop();
}
sndChannel = playlist[id].play();
ID=id;
sndChannel.addEventListener("soundComplete",replayListener);
}
public function replayListener(e){
sndChannel = playlist[ID].play();
}
}
}
import class to you timeline, create instance passing him files list
var musicPlayer = new BackgroundMusicPlayer("music1.mp3","music2.mp3");
And then you want start some sound, call
musicPlayer.playMusic(0);
If you want use imported to project sounds, just share them to actionscript, give them class names and slightly modify given class constructor
public function BackgroundMusicPlayer(srcList:Array){
playlist=[];
for(var i=0;i<srcList.length;i++){
playlist.push(srcList[i]);
}
}
So your instance creation now should be
var musicPlayer = new BackgroundMusicPlayer(new MySound1(),new MySound2());
So I had the issue with ENTER FRAME so I moved it to a separate class and this is what the class looks like
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.accessibility.Accessibility;
import flash.display.DisplayObject;
import flash.display.Stage;
public class enemy extends MovieClip {
public function enemy() {
// constructor code
this.addEventListener(Event.ENTER_FRAME, moveEnemy);
}
public function moveEnemy(e:Event):void{
this.x += 5;
if(stage.player.scaleX == 1){
this.scaleX = 1;
}else {
this.scaleX = -1;
}
}
}
}
Now Im trying to adjust the enemies scalex according to the players but I get a error when referencing the player inside the class can anyone help me solve this?
The trick with using Event.ENTER_FRAME listener is that event.currentTarget will hold the link to the object that's processing the event, event.target will hold the link to the object that's received it first, so you can attach the listener not to the stage, but to the MovieClip of your choice, including having more than a single listener across your game. Say, you give your Enemy class a listener that's making it query stage's list of player's bullets and check collisiong against this, a player can do this too. Or, you use a single listener and do ALL the work inside it, using local arrays to store lists of enemies, bullets, player(s) and other objects.
In terms of passing parameter to enter frame listener - your event is automatically dispatched, so you shouldn't bother with this, and it does not accept more than one parameter.
Regarding your code, you should add enemy movement code in testPlayerCollisions() listener below querying for player collision. For this, you already have an enemy you're about to move, so you just have to call its move() function or whatever you have for it.
It looks like your enemy class doesn't have access to the stage; yet you're trying to reference stage.player. You can access the stage from your main class but not from other classes unless you pass it through the constructor.
Try passing the stage to the enemy class and create a class variable to store it. Ie:
private var stageInst:Stage;
public function enemy(s:Stage){
stageInst = s;
}
Then in moveEnemy use stageInst.player to access the player's clip.
When you create enemy's you'll have to pass in an instance of the stage from Main.
ie: var e:enemy = new enemy(stage);
I have a game that I've made that runs in two files, one the preloader and one the swf. When I use these two files together they work fine, however some flash portals require only one SWF, so I'm trying to find the shortest-path way to convert it to use only one.
The game swf uses a Document Class that includes the package, class constructor, and tons of functions, and runs fine. I have lots of movieclips on the stage that I refer to in my code. The code is something like this (abridged):
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
...
public class Game extends MovieClip {
var EnemyArray:Array;
var HeroArray:Array;
...
public function Game() { // class constructor
EnemyArray = new Array();
addEventListener(Event.ENTER_FRAME,onEnterFrame);
mainRestartButton.addEventListener(MouseEvent.CLICK, RestartLevel);
...
}
public function KeyPressed(event:KeyboardEvent):void
{
if (event.keyCode == Keyboard.SPACE)
{
attack();
...
}
} // End of class
} // End of package
I also have another swf, my preloader, which has the following code in frame 1:
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.ProgressEvent;
import flash.events.Event;
var myLoader:Loader = new Loader();
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoading);
var myURL:URLRequest = new URLRequest("Game.swf");
myLoader.load(myURL);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onLoading(event:ProgressEvent):void {
var loaded:Number = event.bytesLoaded / event.bytesTotal;
percent_txt.text = "Loading: " + (loaded*100).toFixed(0) + "%";
}
function onComplete(event:Event):void {
myLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onLoading);
myLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onComplete);
this.addChild(myLoader);
}
I've been through the gamut of solutions online and none of them seem to work with the way that my code is set up, such as: How to create Preloader in AS3
I tried his option 1 by taking all the code in my Document Class other than the package and constructor and pasted it into frame 2. However it returns "Error #1009: Cannot access a property or method of a null object reference." for any references to items on the stage, such as:
mainRestartButton.addEventListener(MouseEvent.CLICK, RestartLevel);
As he mentions, "This works well if you organized your project in a way that the most of the assets (images, etc) are in the Flash IDE Library and are not loaded on the first frame (you can check that in each library item's properties)." My project is NOT organized in such a way.
What is the easiest way for me to reorganize my FLA/code so they can have a preloader in a single swf?
Thanks so much for your time and help!
I use FlashDevelop (no FLAs) so I'm not sure if it'll work for you but I use the solution described here.
