ActionScript 3.0 :: Updating A Vector.<Number> In A TimerEvent?

Apr 5, 2011

I create a timer and set it to fire events every 500ms:

Code:
t = new Timer(500);
t.addEventListener(TimerEvent.TIMER, onTick);
t.start();

On every tick I would like to add the last 2 elements of a vector to an other vector:

Code:

private function onTick(event : TimerEvent) : void{
tempCoords.push(coords[coords.length - 2],coords[coords.length - 1]);
}

But after the 2nd tick, it doesn't add only those 2 elements but the whole other vector I really don't get what this is happening. I don't use tempCoords anywhere else in my code. The coords vector is updated in a MOUSE_MOVE event with the coordination point of the mouse.

Actionscript 3 :: Vector Number Does Not Extend Vector

Nov 16, 2011

I am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.

Every Vector I've ever tested all extend Vector.<*>.

Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>

[code]...

But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.

<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>

[code]....

Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.

ActionScript 3.0 :: Extending Vector By Number Of Pixels

Mar 16, 2011

I'm trying to extend a line from any given point to the mouse by a certain number of pixels (say, 100). This is the closest I've got: link to SWF. As you can see, the red line is behaving as it should (connecting the "any" point, located at the center of the screen, with the mouse) but the blue line is extending a line from the origin to the mouse by 100 rather than from the "any" point.

The AS3 code on the first frame (shown above, complete below):
Actionscript Code:
import flash.events.Event;
import flash.geom.Point;
function findTermination(
x0:Number,
y0:Number,
[Code] .....

I've expanded the findTermination function as much as I can to make it easier to read (I have a real bad habit of doing everything on as few lines as possible).

Actionscript 3 :: Instantiate A Vector.<Number> With Two Values Of 1.0?

Flash :: Is Vector.<Number> Impossible To Initialize With A Numeric Array

May 29, 2011

How would you go about initializing a Vector. with say the values 1, 2, 3, 4, and 5.

Logic would say you could do newVector = new Vector. ( [1, 2, 3, 4, 5] );

You could also try something like this...

var tmp = [1, 2, 3, 4, 5];
newVector = new Vector.();
newVector = newVector.concat(tmp);

But then you get a type error converting Array to Vector.

I'm stumped, am I missing something stupid or does the vector class really not play well with numeric types? You can try making them decimal numbers just to be sure they get cast as number and not int.

ActionScript 3.0 :: TimerEvent Only Works Once?

Dec 3, 2010

I can only run a timer.start(); command once, the second time it will only run once instead of the value of 10 repeat.

Code:
var addTenPointsTimer:Timer=new Timer(500, 10);
var currentScore = 0;
score.text = "0";

[code]........

I want to be able to have the score add the ten points one at a time rather than all at once. It works fine the first time ten points are added, but the second, third, fourth, etc time it only adds one point then stops. How can I get the timer to work more than once?

ActionScript 3.0 :: Using TimerEvent In While Loop

Oct 14, 2009

I am attempting to use a TimerEvent in a while loop. In the example I have created below, the init function should loop through the values myArray, tracing each value at three second intervals. It seems, however, that because I am incrementing the currentNum value outside of the while loop (in the timerHandler function), that the loop just keeps running until Flash stops responding.[code]

ActionScript 3.0 :: TimerEvent Preventing A GotoAndPlay?

Sep 7, 2009

I have a movie clip, asterixHolder, with multiple frames that is instructed, at times, to gotoAndPlay at a particular frame (where'currentSection' is a number):

Code:
asterixHolder.gotoAndPlay("tween"+currentSection); Nested inside asterixHolder is a clip called theAsterix that I want to continually rotate. I've been achieving this with a Timer Event:

[Code]...

However, when the TimerEvent code is included - or to be more precise, when the function timerHandler references asterixHolder - the previous code to send the clip to the appropriate frame does not work. Could anyone tell me why this is the case? It doesn't seem logical that calling a nested clip should prevent the parent clip from doing anything.

ActionScript 3.0 :: Starting A Preloader From A TimerEvent

Oct 5, 2009

Before I start my preloader animation, I want to play a quick animation. I was hoping to use a TimerEvent to delay the preloader from starting until the animation was over, but nothing's happening.I cobbled this together from other preloader tutorials, and since I'm not sure I understand how it all works, I shouldn't be too surprised that my hybrid failed.[code]I don't register either trace statement, but if I move this. loaderInfo.add EventListener (ProgressEvent.PRO GRESS, check_progress); out of the timer event function, then I get the trace statement just fine.

ActionScript 3.0 :: Using TimerEvent To Control Banner Animation?

Nov 18, 2009

Very new to AS3 and wasn't a strong coder to begin with - I've been asked to build a large banner revealing multiple ads (4 to be precise). My thought is to use a TimerEvent (if, then type statement) to control how long each "billboard" will be on the stage, then have the next one slide onto the stage...etc, etc... I'm finding conflicting codes out there, and don't know which to pull from. This seems easy in my head, but the AS3 code appears very complex to pull this off.

ActionScript 3.0 :: Custom Dragger With TimerEvent. Drag From Original Position?

Apr 8, 2009

I prefer to build custom drag functions using the TimeEvent etc. Below I have some code where as when I click on a MovieClip it fires the imageStartDrag function which then begins the imageDrag function consecutively.Currently when I click and drag it moves the image fine, however it is snapping to the far left of the image.What I would like is to be able to click and drag so that the image drags from it's original point. My brain is a bit confused, what do I edit in 'imageLoader.x = mouseX;' to have it starting from it's original position and moving. (Note, I'm only testing with the X Axis atm, later it will use the Y Axis too.)

Flash - Timer Object With TimerEvent.TIMER Event Globally Accessible To All Objects?

Feb 16, 2012

I am working on a very simple game in Flash. I want to make all the animations framerate agnostic, so that I can change the framerate without affecting the flow and speed of the game.I read somewhere that if you want to do that, you simply create a Timer object and attach an event listener to this timer.

What if I have many objects that have to listen to the same timer? See the code to understand what I am trying to do. At this stage nothing breaks, but the event does not fire.Here is the Main class, the one that runs on swf execution:

public class Main extends MovieClip {
private static var _stage:Stage;
private static var _timer:Timer;

ActionScript 3.0 :: Divinding Vector Graphics Into Vector Graphics

Jul 28, 2009

I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.

I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?

Inside my code i have some variables declared as Numbers, and i get some others from an external source; these variables can either be Numbers or String representation of Numbers. Now, i have to implement some equality controls on these variables, and since i don't know in that moment which type are them of, i'm converting all of them to Numbers (i don't need and neither want to compare strings) via the Number() function which accepts either Numbers or Strings as an input. These controls can compare 2 single variables or a variable and a sum (or subtraction) of other variables, for example:
