I need to have a swf load at the beginning, but I don't want to play about the last 3 seconds of the video.
Can someone help me out with a code that would basically have my swf play for "x" seconds?
Heres what I Have so far.. Currently it is set up to play the swf, but subtract "x" seconds from it but for some reason it doesn't seem to work
var mySwf:MovieClip;
var reducedTotalFrames:int;
var clipLoader:Loader = new Loader();
clipLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
clipLoader.load(new URLRequest("schoolintro.swf"));
function loadComplete(e:Event):void
{
mySwf = LoaderInfo(e.currentTarget).content as MovieClip;
var totalFrameCount:int = mySwf.currentScene.numFrames;
var secondsToSubtract:int = 3;
var threeSecondFrameCount:int = (stage.frameRate * secondsToSubtract);
reducedTotalFrames = totalFrameCount - threeSecondFrameCount;
stage.addEventListener(Event.ENTER_FRAME, onRender);
stage.addChild(mySwf);
}
function onRender(e:Event):void
{
if(mySwf != null && mySwf.currentFrame >= reducedTotalFrames){
//This is the end of the SWF with 3 seconds trimmed off. Here we can stop play
stage.removeEventListener(Event.ENTER_FRAME, onRender);
mySwf.stop();
//doSomethingElse();
}
}
Try some basic debugging, like placing trace statements in the code inside onRender to ensure it's being called, to ensure the mySwf reference is working correctly (for example, tracing out mySwf.currentScene.numFrames, and if its 0, you know you're not referencing your swf properly or the swf is not frame-based). If it the SWF is not frame-based, then you're going to have real issues controlling or even doing anything about this since all the animation/action going on inside the loaded SWF is code-based.
I think you just need to change this line from
var threeSecondFrameCount:int = (stage.frameRate * secondsToSubtract);
to
var threeSecondFrameCount:int = (stage.frameRate / secondsToSubtract);
not sure is this what you want or not.

I have this annoying issue that I hope someone might be able to help me with.
I have a mute button that I created and I have another movieclip inside of that button. All I want it to do is when I toggle the mute the movieclip inside will go to the according frame.
However, every time I try to call the movieclip inside of the button, this error comes up:
Access of possibly undefined property mcMuteToggle through a reference with static type flash.display:SimpleButton.
The instance name for the movieclip within is "mcMuteToggle".
Why not make movieClips that act like buttons?? Since I dont think actual button (simpleButton) types can deal with sub-MovieClips (especially if they too have code). Even if possible don't do it, I can predict a mess whereby Button does things it shouldn't do depending on what code you have in those MClips.
Try an alternate button method, just for a test... You didnt show any test code to work with so I will make assumptions..
1) Make a shape (rectangle?) and convert to MovieClip (or if all coded, then addchild shape to new MovieClip). Let's assume you called it mc_testBtn.
2) Make that MC clickable by coding mc_testBtn.buttonMode = true;
3) Add your mcMuteToggle inside the mc_testBtn
(or by code: mc_testBtn.addChild(mcMuteToggle);
Now you can try something like..
mc_testBtn.addEventListener (MouseEvent.CLICK, toggle_Mute );
function toggle_Mute (evt:MouseEvent) : void
{
if ( whatever condition )
{
mc_testBtn.mcMuteToggle.gotoAndStop(2); //go frame 2
}
else
{
mc_testBtn.mcMuteToggle.gotoAndStop(1); //go frame 1
}
}
This is likely due to strict mode. You can either disable it in the ActionScript settings dialog, access it with a different syntax myButton['mcMuteToggle'], or make a class for the symbol that includes a property mcMuteToggle.
You can also check to make sure the symbol is actually on the stage and that clip is actually in the button:
if('myButton' in root) {
// ...
}
if('mcMuteToggle' in myButton) {
// ...
}
i think u just overwrite that codes. You u can use something like this:
var soundOpen:Boolean = true;
var mySound:Sound = new Sound(new URLRequest("Whatever your sound is"));
var mySc:SoundChannel = new SoundChannel();
var mySt:SoundTransform = new SoundTransform();
mySc = mySound.play();
mcMuteToggle.addEventListener(MouseEvent.CLICK, muteOpenSound);
function muteOpenSound(e:MouseEvent):void
{
if(soundOpen == true)
{
mcMuteToggle.gotoAndStop(2);
/*on frame 2 u need to hold ur soundClose buton so ppl can see :)*/
soundOpen = false;
mySt.volume = 0;
mySc.soundTransfrom = st;
}
else
{
mcMuteToggle.gotoAndStop(1);
soundOpen = true;
mySt.volume = 1;
mySc.soundTransfrom = st;
}
}
This is working for me everytime. Hope u can use it well ;)
I'am trying to make a scoring system by using a timer so that it work on the basis that as the player keeps on going the timer/score keeps on going up and I got that to work with this code.
var nCount:Number = 0;
var myScore:Timer = new Timer(10, nCount);
score_txt.text = nCount.toString();
myScore.start();
myScore.addEventListener(TimerEvent.TIMER, countdown);
function countdown(e:TimerEvent):void{
nCount++;
score_txt.text = nCount.toString();
}
However say for example the player crashes I want the game to remember the score and then display it on another frame where I have a game over screen so that it shows the final score to the player and this is the part that I have no idea how to do. Any help would be appreciated.
Many Thanks
You can't modify objects on "another frame". You can only modify objects on the current frame. The frames simply represent state that is baked into the SWF to be actualized when the timeline reaches those frames; you cannot change SWF frame data at runtime. You can only change the resulting objects once those frames are constructed by the player.
What you can do is store your score in a variable (available across all frames) and simply set the correct text objects when you are on those frames.
For your code, you simply need to only set the nCount to 0 when the SWF loads (or you want to reset it), and set the score_txt immediately on the frame it exists. For example, you could do it like this:
// Don't initialize a value, that would overwrite
// it every time this frame is visited
var nCount:Number;
// Only the first time, when the value is NaN, set the score to 0
if(isNaN(nCount)){
nCount = 0;
}
// Immediately show the current score text
score_txt.text = nCount.toString();
// The rest stays the same
var myScore:Timer = new Timer(10, nCount);
score_txt.text = nCount.toString();
myScore.start();
myScore.addEventListener(TimerEvent.TIMER, countdown);
function countdown(e:TimerEvent):void{
nCount++;
score_txt.text = nCount.toString();
}
Currently I have an intro screen to my flash file which has two objects.
A button which will load an external flash file using:
var myLoader:Loader = new Loader();
var url:URLRequest = new URLRequest("flashgame.swf");
The second thing is a Numeric Stepper, which will be from 1 to 10. If the user selects a number e.g. 3 then the game speed I have set in the flashgame.swf should be changed
Such as:
var gameSpeed:uint = 10 * numericStepper.value;
But I think my problem is coming into place because the stepper and gamespeed are from different files.
Anyone got any idea please?
I have also tried creating a stepper in the game file and used this code:
var gameLevel:NumericStepper = new NumericStepper();
gameLevel.maximum = 10;
gameLevel.minimum = 1;
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
For some reason the stepper just flashes on the stage, no errors come up and the game doesn't work
When you execute you code, the stepper has no chance to wait for user input.
There is no time between theese two instructions.
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
You should wait for user input in your NumericStepper, and then, on user event, set the game speed.
Edit: Yeah I know it's kinda sad to type out all this code (especially since some people wouldn't even be grateful enough to say thanks) but I think this question is important enough to justify the code as it may be helpful to others in future also.
Hi,
You were close. In your game file you could have put a var _setgameSpeed and then from Intro you could adjust it by flashgame._setgameSpeed = gameSpeed; It's a bit more complicated though since you also have to setup a reference to flashgame in the first place. Let me explain...
Ideally you want to put all your code in one place (an .as file would be best but...) if you would rather use timeline then you should create a new empty layer called "actions" and put all your code in the first frame of that.
Also change your button to a movieClip type and remove any code within it since everything will be controlled by the code in "actions" layer. In the example I have that movieclip on the stage with instance name of "btn_load_SWF"
Intro.swf (Parent SWF file)
var my_Game_Swf:MovieClip; //reference name when accessing "flashgame.swf"
var _SWF_is_loaded:Boolean = false; //initial value
var set_gameSpeed:int; //temp value holder for speed
var swf_loader:Loader = new Loader();
btn_load_SWF.buttonMode = true; //instance name of movieclip used as "load" button
btn_load_SWF.addEventListener(MouseEvent.CLICK, load_Game_SWF);
function load_Game_SWF (event:MouseEvent) : void
{
//set_gameSpeed = 10 * numericStepper.value;
set_gameSpeed = 100; //manual set cos I dont have the above numericStepper
if ( _SWF_is_loaded == true)
{
stage.removeChild(swf_loader);
swf_loader.load ( new URLRequest ("flashgame.swf") );
}
else
{ swf_loader.load ( new URLRequest ("flashgame.swf") ); }
swf_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, Game_SWF_ready);
}
function Game_SWF_ready (evt:Event) : void
{
swf_loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, Game_SWF_ready);
//Treat the Loader contents (flashgame.swf) as a MovieClip named "my_Game_Swf"
my_Game_Swf = swf_loader.content as MovieClip;
my_Game_Swf.gameSpeed = set_gameSpeed; //update gameSpeed variable in flashgame.swf
//also adjust SWF placement (.x and .y positions etc) here if necessary
stage.addChild(my_Game_Swf);
_SWF_is_loaded = true;
}
Now in you flashgame file make sure the there's also an actions layers and put in code like this below then compile it first before debugging the Intro/Parent file. When your Intro loads the flashgame.swf it should load an swf that already has the code below compiled.
flashgame.swf
var gameSpeed:int;
gameSpeed = 0; //initial value & will be changed by parent
addEventListener(Event.ADDED_TO_STAGE, onAdded_toStage);
function onAdded_toStage (e:Event):void
{
trace("trace gameSpeed is.." + String(gameSpeed)); //confirm speed in Debugger
//*** Example usage ***
var my_shape:Shape = new Shape();
my_shape.graphics.lineStyle(5, 0xFF0000, 5);
my_shape.graphics.moveTo(10, 50);
my_shape.graphics.lineTo(gameSpeed * 10, 50); //this line length is affected by gameSpeed as set in parent SWF
addChild(my_shape);
}
The key line in intro.swf is this: my_Game_Swf.gameSpeed = set_gameSpeed; as it updates a variable in flashgame.swf (referred as my_Game_Swf) with an amount that is taken from a variable in the Parent SWF.
This is just one way you can access information between two separate SWF files. Hope it helps out.
I have to do a very simple swf application able to show a series of pdf files.
Actually I was able to create on a single layer the menu interface (some buttons on frame 0 which redirect the user to other frames where the pdf should be showed).
Here my question:
I need a way to read the pdf inside the flash frame.
I've found a possible solution converting the pdf into an swf with FlashPaper 2
Now I wish to know how import the swf into the frame.
Reading some actionscript 3 guides I was able to create a container movieclip (a simple rectangle) into which I have loaded the swf with this code:
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("test.swf"); //test.swf is my converted pdf
loader.load(defaultSWF);
screen_01.addChild(loader); //screen_01 is the container rectangle converted to movieclip
I've used a container movieclip to mantain the other objects (menu buttons) on the frame, and ecause it helps with the swf positioning.
I seen it is possible also using loader.x and loader.y and it works.
Unfortunately I wasn't able to control width and height of the swf/pdf file (loader.width and loader.height exists but if used cause the swf will not loaded at all)
Solution:
I've found a possible solution at this page. The idea is to change swf scale only after the load process is complete (positioning can be done even before).
Anyway I had to use Actionscript 2 for this project because FlashPaper converted pdf doesn't work properly with AS3, I don't know why...
here the code:
//insert an emplty movieclip to load the swf, I've called it screen_01
var movLoad:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
myListener.onLoadInit = function(thisMc:MovieClip) {
thisMc._height = 600;
thisMc._width = 900;
thisMc._x = 50;
thisMc._y = 30;
};
movLoad.addListener(myListener);
movLoad.loadClip("folder/flashpaper_converted_pdf.swf.swf",screen_01);
You can modify the size of the loader using scaleX and scaleY properties.
Keep them equals so the swf isn't stretched.
You may also want to listen to the COMPLETE event to do such a thing :
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event)
{
var loader:Loader = e.currentTarget.loader;
loader.scaleX = loader.scaleY = 2; //Double the size of the loaded swf
}
I am a Flash and ActionScript newbie. I am trying to follow a video tutorial to make a preloader and I'm having a problem that the video didn't seem to address. I believe I have entered in all of the code correctly from the video. This is it:
stop();
addEventListener(Event.ENTER_FRAME, loaderF);
function loaderF(e:Event):void{
var toLoad:Number = loaderInfo.bytesTotal;
var loaded:Number = loaderInfo.bytesLoaded;
var total:Number = loaded/toLoad;
if( loaded == toLoad ){
removeEventListener(Event.ENTER_FRAME, loaderF);
gotoAndStop(2);
} else {
preloader_mc.preloaderFill_mc.scaleX = total;
preloader_mc.percent_txt.text = Math.floor( total * 100 ) + "%";
preloader_mc.ofBytes_txt.text = loaded + "bytes";
preloader_mc.totalBytes_txt.text = toLoad + "bytes";
}
}
What I typed in doesn't generate a compiler error, but the output tells me:
TypeError: Error #1010: A term is undefined and has no properties.
at preloader_fla::MainTimeline/loaderF()
And since I really don't have any experience outside of what I'm learning from this tutorial series, I don't know what to do to fix this.
I don't use Flash CS5, but you should be able to get the line # for where the error is occurring, I believe, by executing the SWF by pressing CTRL+SHIFT+ENTER.
Once you get the line number, you should see that something on that line is null or not defined. The error says it occurs in the function loaderF(), and looking at that code the only place such an error could occur is in the else block:
} else {
preloader_mc.preloaderFill_mc.scaleX = total;
preloader_mc.percent_txt.text = Math.floor( total * 100 ) + "%";
preloader_mc.ofBytes_txt.text = loaded + "bytes";
preloader_mc.totalBytes_txt.text = toLoad + "bytes";
}
In the above code block, one of these things is not defined:
preloader_mc.preloaderFill_mc,
preloader_mc.percent_txt,
preloader_mc.ofBytes_txt,
preloader_mc.totalBytes_txt
Maybe your preloader movie clip is missing one of these objects...
First, you'll want to turn on debugging found under (File > Publish Settings > Flash (.swf) > Permit Debugging). This will provide line numbers and allow additional debugging to help track down errors.
Secondly, in the code sample you've provided, you haven't declared a loader, so when you call on loaderInfo, it makes sense that flash complains about "a term is undefined". Although, technically, the loaderInfo object is a child of the event object. Thus, loaderInfo.bytesTotal would become e.loaderInfo.bytesTotal, assuming you added the event listener to the loader object; currently yours is added to the timeline.
Bookmark Adobe's Actionscript 3.0 Reference. Use it. As you begin your journey in Flash, this will be your indispensable handbook to speaking AS3. Specifically, you'll want to refer to the Loader class.
Here's what you're likely missing in your code:
var myLoader:Loader = new Loader();
myLoader.load(new URLRequest("path/to/my/file"));
Your function loaderF is being called during every frame update to the screen (likely every .034 seconds). You'd probably be happier with ProgressEvent.PROGRESS instead of Event.ENTER_FRAME. If so, you'll also want to catch the complete event, and that'd look like this:
myLoader.addEventListener(Event.COMPLETE, loadComplete);
myLoader.addEventListener(ProgressEvent.PROGRESS, loadProgress);
function loadComplete(e:Event):void {
// Stuff to do when the file finishes loading.
}
function loadProgress(e:Event):void {
var current:int = e.bytesLoaded;
var total:int = e.bytesTotal;
var percent:Number = current/total;
// Update the readout of your loading progress.
}
Hopefully that points you in the right direction. :)
