I'm using Flash Pro CS6 to make an easy game where some cubes drop. I added a text field (instance name is timerText) where I wat the time to display. Here is the code:
var time:int =0;
var timer:Timer = new Timer(1000,0);
timer.start();
timer.addEventListener(TimerEvent.TIMER, cubeFall);
function cubeFall(t:TimerEvent) {
time++;
timerText.text = time.toString();
if (time == 3) {
cube_1.play();
}
}
My problem is that the text field, when the game starts, after 1 second the number 1 appears, but it doesn't continue. Any Ideas why?
Your code works fine for me? (Flash CS5.5 output to Flash Plater 10.2).
Try setting the textfield font to _sans. If that works it might be due to you needing to embed the font.
var time:int =0;
var timer:Timer = new Timer(1000,0);
timer.addEventListener(TimerEvent.TIMER, cubeFall);
timer.start();
function cubeFall(t:TimerEvent) {
time++;
timerText.text = time.toString();
if (time == 3) {
cube_1.play();
}
}
//try this one you set the event and then start

I developed a code that is going to load a movie clip making a comparison with two dynamic text.
If dynamic text is greater than the other one, it will lunch a specific movie clip. I[m trying to develop a light sign system comparing numbers.
Action script is importing data from .txt files (exported using EXCEL and VBA). I created a code to reload all data using a timer. I create that so it's not necessary to reopen the .swf file.
Here is the automatically reload code:
// timer loading
var timer:Timer = new Timer(2500);
timer.addEventListener(TimerEvent.TIMER, onTimer);
timer.start();
Now, the code is being applied to all actions, include an action to redownload the .txt files, here it is:
function onTimer(evt:TimerEvent):void { //primeiro indicador parte
var loader:URLLoader = new URLLoader(new URLRequest("bdaily.txt"));
loader.addEventListener(Event.COMPLETE, completeHandler);
function completeHandler(event:Event):void {
var loadedText:URLLoader = URLLoader(event.target); bdaily.text = loadedText.data;
}
Now, this code is comparing the .txt (dynamic text) and loading or not loading a new movie clip.
var clp_index = parseInt(bdaily.text) >= parseInt(basketdtarget.text) ? 1 : 2
var new_clp = clp_index == 1 ? new clp_01() : new clp_02()
addChild(new_clp)
The PROBLEM IS:
-> Everything is working fine, all data is being loaded and are shown in the dynamic text.
The real thing is that all movie clips are being loaded in an infinite loop due the loop timer set, a lot of ram memory is being consumed. The code is working but its loading movie clips above movie clip.
I need to implement my code and insert a code to erase the movie clips after calling the loop again.
There are a few ways you can accomplish this. I'll show a couple of them.
Make your new_clp var global to the current class or timeline (move it's declaration to the same place as your timer)
var timer:Timer = new Timer(2500);
timer.addEventListener(TimerEvent.TIMER, onTimer);
timer.start();
var new_clp:DisplayObject;
Then, remove it before creating a new clip:
if(new_clp){ //if there is already something in this variable, then remove it
removeChild(new_clp);
}
var clp_index = parseInt(bdaily.text) >= parseInt(basketdtarget.text) ? 1 : 2
new_clp = clp_index == 1 ? new clp_01() : new clp_02()
addChild(new_clp)
Walk the current scopes display list and remove all clp_01 and clp_02 instances:
var i:int = numChildren;
while(i--){
if(getChildAt(i) is clp_01 || getChildAt(i) is clp_02){
removeChild(getChildAt(i));
//if you have any listeners attached to the object, remove them now
}
}
var clp_index = parseInt(bdaily.text) >= parseInt(basketdtarget.text) ? 1 : 2
var new_clp = clp_index == 1 ? new clp_01() : new clp_02()
addChild(new_clp)
Something else to consider for memory management, is if you only have the two clips, just keep them both loaded all the time, and change the visibility of them every timer tick:
var timer:Timer = new Timer(2500);
timer.addEventListener(TimerEvent.TIMER, onTimer);
timer.start();
var clp1:clp_01 = new clp_01;
var clp2:clp_02 = new clp_02;
addChild(clp1);
addChild(clp2);
Then in your other block of code:
var clp_index = parseInt(bdaily.text) >= parseInt(basketdtarget.text) ? 1 : 2
clp1.visible = clp_index == 1;
clp2.visible = clp_index == 2;
I’m resurrecting a simple banner where we used an FLV movie and the following code to have the movie pause using setInterval and then play again. It’s a simple butterfly movie that flaps it’s wings and then goes back to a static state.
Looks like FLVs are now discouraged in the more recent Flash versions so I would like to know how to make a movie play, then pause using setInterval, then replay.
Here is the working AS3 when using an FLV on the Timeline in a frame based animation but does not work with an imported .mp4:
stop();
function timesUp()
{
gotoAndPlay(1,"Scene 1");
clearInterval(itv);
}
var itv=setInterval(timesUp, 15000);
Do the new suggested methods use a single frame movie where you load and play the mp4, then use setInterval as a timer to replay?
I can’t find any tutorials that have this method as an example.
I did read a tutorial on the Adobe site but the following did not load and play the movie (morpho.mp4)
var nc:NetConnection = new NetConnection();
nc.connect(null);
var vid:Video = new Video();
addChild(vid);
var ns:NetStream = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
function netStatusHandler(event:NetStatusEvent):void
{
// handle netStatus events, described later
}
function asyncErrorHandler(event:AsyncErrorEvent):void
{
// ignore error
}
vid.attachNetStream(ns);
ns.play("morpho.mp4");
Try this :
import flash.utils.Timer
import flash.events.TimerEvent
var video_playing:Boolean = false,
timer:Timer,
nc:NetConnection,
ns:NetStream,
video:Video,
video_name:String = 'video.mp4'
nc = new NetConnection()
nc.connect(null)
ns = new NetStream(nc)
ns.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
function netStatusHandler(event:NetStatusEvent):void {
switch (event.info.code){
case 'NetStream.Play.Start' :
if(timer.currentCount == 0){
timer.start()
}
break
}
}
function asyncErrorHandler(event:AsyncErrorEvent):void {
}
video = new Video(135, 135) // set the size of video to 135x135px
video.x = 165 // set the left of video to 300 - 135 = 165px
video.y = 0 // set the top of video to 0
video.attachNetStream(ns)
addChild(video)
timer = new Timer(1000, 3) // 3 seconds, just for example
timer.addEventListener(TimerEvent.TIMER_COMPLETE, timer_on_Complete)
function timer_on_Complete(e:TimerEvent){
if(video_playing){
video_playing = false
ns.close()
} else {
start_video()
}
timer.reset()
timer.start()
}
start_video()
function start_video(){
ns.play(video_name)
video_playing = true
}
I would like to make my Flash AS3 based app more accessible with a keyboard navigation.
What's the best way to add to every MovieClip with a MouseEvent.CLICK the ability to get selected through the TAB and clicked/fired through ENTER?
Some basic example of my code:
nav.btna.addEventListener(MouseEvent.CLICK, openSection);
dialog.btnx.addEventListener(MouseEvent.CLICK, closeDialog);
function openSection(event:Event=null):void
{
trace("nav.btna")
}
function closeDialog(event:Event=null):void
{
trace("dialog.btnx")
}
I remember that there was a AS3 function that enabled that every MovieClip with a MouseEvent could be fire through ENTER if the MovieClip was selected with TAB. I can't remeber the function though.
I think the problem may be that you are attempting this with a MovieClip instead of a button (Button or SimpleButton).
I made a simple test by creating buttons instead of MovieClips in my library and this worked as expected:
// I have 4 buttons (button1, button2, etc) on the stage
for(var i:int = 1; i <= 4; i++)
{
var mc = getChildByName("button" + (i+1));
mc.tabIndex = i;
mc.addEventListener(MouseEvent.CLICK, onClicked);
}
function onClicked(e:MouseEvent):void
{
trace(e.currentTarget + " clicked");
}
stage.focus = stage;
I initially ran this test with MovieClip instances, and while they would show that the tab was working (a yellow border shows up), the MouseEvent.CLICK was never firing. Once I switched to actual buttons (SimpleButton in this case), it worked with both the Enter and Space keys.
EDIT:
To answer the question posed in the comments, this is a quick-and-dirty way to "convert" MovieClips to SimpleButtons at runtime:
// I have 4 MovieClips (button1, button2, etc) on the stage
for(var i:int = 1; i <= 4; i++)
{
var mc:MovieClip = getChildByName("button" + i) as MovieClip;
var button:SimpleButton = convertMovieClipToButton(mc);
button.tabIndex = i;
button.addEventListener(MouseEvent.CLICK, onClicked);
}
function convertMovieClipToButton(mc:MovieClip):SimpleButton
{
var className:Class = getDefinitionByName(getQualifiedClassName(mc)) as Class;
var button:SimpleButton = new SimpleButton(new className(), new className(), new className(), new className());
button.name = mc.name;
button.x = mc.x;
button.y = mc.y;
mc.parent.addChildAt(button, getChildIndex(mc));
mc.parent.removeChild(mc);
return button;
}
I am currently in a Flash game programming class with action script 3 and can't seem to find a clock anywhere that counts down and then does an action. I've been using Lynda tutorials and that hasn't been helpful and I have also Google searched quite a bit, but no luck. I have a Countdown clock and have been try "if" statements, but no luck.
Can someone guide me in the right direction on what I am doing wrong?
//game timer
var count:Number = 60; // amount of time
var myTimer:Timer = new Timer(1000,count); // time in ms, count is calling from line above
myTimer.addEventListener(TimerEvent.TIMER, countdown);
myTimer.start();
function countdown(event:TimerEvent):void
{
myText_txt.text = String((count)-myTimer.currentCount); //dynamic txt box shows current count
}
//if and else if statements
if (((count)-myTimer.currentCount) == 58)
{
gotoAndStop(2);
}
This should help ;) Without any magic numbers.
var myTimer:Timer = new Timer(1000,60); // every second for 60 seconds
myTimer.addEventListener(TimerEvent.TIMER, onTimer);
myTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onComplete);
myTimer.start();
function onTimer(e: TimerEvent):void {
myText_txt.text = String(myTimer.repeatCount - myTimer.currentCount);
}
function onComplete(e: TimerEvent):void{
gotoAndStop(2);
}
Add your if statement inside countdown like so:
function countdown(event:TimerEvent):void
{
myText_txt.text = String((count)-myTimer.currentCount); //dynamic txt box shows current count
//if and else if statements
if (((count)-myTimer.currentCount) == 58)
{
gotoAndStop(2);
}
}
I'm trying to make a custom animated/shooter, from this tutorial: http://flashadvanced.com/creating-small-shooting-game-as3/
By custom, I mean customized, ie, my own version of it.
In it's actionscript, there's a timer event listener with function: timerHandler()
This function adds and removes child "star" objects on the stage (which the user has to shoot at):
if(starAdded){
removeChild(star);
}
and :
addChild(star);
Code works great, but error occurs on scene 2.
The code works great, and I even added some code while learning via google and stackflow to this flash file. I added Scene 2 to it too, and had it called after 9 seconds of movie time. But when it goes to Scene 2, it still displays the star objects and I've been unable to remove these "star" object(s) from Scene 2.
Here's the code I added:
SCENE 1:
var my_timer = new Timer(5000,0); //in milliseconds
my_timer.addEventListener(TimerEvent.TIMER, catchTimer);
my_timer.start();
var myInt:int = getTimer() * 0.001;
var startTime:int = getTimer();
var currentTime:int = getTimer();
var timeRunning:int = (currentTime - startTime) * 0.001; // this is how many seconds the game has been running.
demo_txt.text = timeRunning.toString();
function catchTimer(e:TimerEvent)
{
gotoAndPlay(1, "Scene 2");
}
SCENE 2:
addEventListener(Event.ENTER_FRAME,myFunction);
function myFunction(event:Event) {
timer.stop();
timer.removeEventListener(TimerEvent.TIMER, timerHandler);
stage.removeChild(star);
stage.removeEventListener(MouseEvent.MOUSE_MOVE, cursorMoveHandler);
my_timer.stop(); // you might need to cast this into Timer object
my_timer.removeEventListener(TimerEvent.TIMER, catchTimer);
Mouse.show();
}
stop();
=====================================================
I'm quite new as3, and have just created an account on StackOverflow... even though I've known and read many codes on it since quite some time.
Here's the Edited New Complete Code:
//importing tween classes
import fl.transitions.easing.*;
import fl.transitions.Tween;
//hiding the cursor
Mouse.hide();
//creating a new Star instance
var star:Star = new Star();
var game:Game = new Game();
//creating the timer
var timer:Timer = new Timer(1000);
//we create variables for random X and Y positions
var randomX:Number;
var randomY:Number;
var t:int = 0;
//variable for the alpha tween effect
var tween:Tween;
//we check if a star instance is already added to the stage
var starAdded:Boolean = false;
//we count the points
var points:int = 0;
//adding event handler on mouse move
stage.addEventListener(MouseEvent.MOUSE_MOVE, cursorMoveHandler);
//adding event handler to the timer
timer.addEventListener(TimerEvent.TIMER, timerHandler);
//starting the timer
timer.start();
addChild(game);
function cursorMoveHandler(e:Event):void{
//sight position matches the mouse position
game.Sight.x = mouseX;
game.Sight.y = mouseY;
}
function timerHandler(e:TimerEvent):void{
//first we need to remove the star from the stage if already added
if(starAdded){
removeChild(star);
}
//positioning the star on a random position
randomX = Math.random()*500;
randomY = Math.random()*300;
star.x = randomX;
star.y = randomY;
//adding the star to the stage
addChild(star);
//changing our boolean value to true
starAdded = true;
//adding a mouse click handler to the star
star.addEventListener(MouseEvent.CLICK, clickHandler);
//animating the star's appearance
tween = new Tween(star, "alpha", Strong.easeOut, 0, 1, 3, true);
t++;
if(t>=5) {
gotoAndPlay(5);
}
}
function clickHandler(e:Event):void{
//when we click/shoot a star we increment the points
points ++;
//showing the result in the text field
points_txt.text = points.toString();
}
And on Frame 5 :
//timer.stop();
//timer.removeEventListener(TimerEvent.TIMER, timerHandler);
// uncomment lines above if "timer" is something you've made
stage.removeChild(star);
stage.removeEventListener(MouseEvent.MOUSE_MOVE, cursorMoveHandler);
timer.stop(); // you might need to cast this into Timer object
timer.removeEventListener(TimerEvent.TIMER, timerHandler);
Mouse.show();
stop();
There's no Scene 2 now, in this new .fla file...
Here's a screenshot of the library property of my flash file...: http://i.imgur.com/d2cPyOx.jpg
You'd better drop scenes altogether, they are pretty much deprecated in AS3. Instead, use Game object that contains all the cursor, stars and other stuff that's inside the game, and instead of going with gotoAndPlay() do removeChild(game); addChild(scoreboard); where "scoreboard" is another container class that will display your score.
Regarding your code, you stop having a valid handle to stage that actually contains that star of yours, because your have changed the scene. So do all of this before calling gotoAndPlay() in your catchTimer function.
function catchTimer(e:TimerEvent)
{
//timer.stop();
//timer.removeEventListener(TimerEvent.TIMER, timerHandler);
// uncomment lines above if "timer" is something you've made
stage.removeChild(star);
stage.removeEventListener(MouseEvent.MOUSE_MOVE, cursorMoveHandler);
my_timer.stop(); // you might need to cast this into Timer object
my_timer.removeEventListener(TimerEvent.TIMER, catchTimer);
Mouse.show();
gotoAndPlay(1, "Scene 2");
}
And the code for Scene 2 will consist of a single stop() - until you'll add something there. Also, there should be no event listeners, especially enter-frame, without a code to remove that listener! You add an enter-frame listener on Scene 2 and never remove it, while you need that code to only run once.
Use getChildAt.
function catchTimer(e:TimerEvent)
{
var childCount:int = this.numChildren - 1;
var i:int;
var tempObj:DisplayObject;
for (i = 0; i < childCount; i++)
{
tempObj = this.getChildAt(i);
this.removeChild(tempObj);
}
gotoAndPlay(1, "Scene 2");
}
This will remove all the children you added on scene 1 before going to scene 2.
