How can you increase performance?

Hello
I'm building a site, but it's the framerate is very slow.

I read a few articles that the Sprites are much faster then movieclips.

For example, I have 5 long movieclips (4300 pixels in width). These clips scroll horizontally to achieve a parallax effect.

One of these movieclips contains other movieclips. (all movieclips not animate and are just graphic).

So I thought to increase performance to convert all the clips of Sprites that I read that the Sprites are better for performance.
I came up with this method:

function castMovieClipToSprite(source:MovieClip,_recursive:Boolean_=_true):void {}

for (var i: int = 0; i < source.numChildren; i ++) {}

var child: DisplayObject = source.getChildAt (i) as DisplayObject;

If (child is MovieClip & & recursive) {}

castMovieClipToSprite (MovieClip (child), recursive);

     }

child = Sprite (child);

     }

}

The performance has improved slightly, but if I run the debugger I see that child objects are always of type MovieClip.

Does anyone know another way to improve performance?

Thank you

Chris.

At the point of several objects, the following code does the same job (looks like) in your demonstration with a single shape:

var angleConvert:Number = Math.PI / 180;
var numSegments:int = 100;
var angleIncrement:Number = angleConvert * (360 / numSegments);
var radius:Number = Math.max(stage.stageWidth, stage.stageHeight);
var currentAngle:Number = 0;
rays = new Shape();
var g:Graphics = rays.graphics;
g.beginFill(0x000000);
g.drawRect( -radius, -radius, radius * 2, radius * 2);
var len:int = numSegments / 2;
for (var i:int = 0; i < len; i++) {
     g.beginFill(0xC0C0C0);
     g.moveTo(0, 0);
     g.lineTo(radius * Math.cos(currentAngle), radius * Math.sin(currentAngle));
     currentAngle += angleIncrement;
     g.lineTo(radius * Math.cos(currentAngle), radius * Math.sin(currentAngle));
     g.endFill();
     currentAngle += angleIncrement;
}
addChild(rays);
rays.x = radius * .5;
rays.y = 100;

addEventListener(Event.ENTER_FRAME, rotate);

function rotate(e:Event):void
{
     rays.rotation += 1;
}

    Hi John,.

    You can add styles that are only used when printing (or print preview). In the frame header HTML on your page (or in the header section of the page template if you want on all pages), add something like:

    <style type="text/css" media="print">
* {font-size:24px!important;}
</style>

    This will set all the text to 24 px. Obviously, adjust according to your needs.

  • How can you increase or zoom to the size of the points of control/tabs menu bar? They are tiny in HD resolution.

    I have a big screen and I put high resolution. This makes it very small. I bring it to the top with no squint, but it does not work on the superior/tool menu bar/control/tabs or their menus, leaving me squinting again scrolling. There must be no feature squint for this area of the browser

    NoSquint changes only the display of web page, not the user interface of Firefox.

    How big is "big"? The size of attachments to e-mails usually is limited by your email provider (normally your Internet service provider) and not necessarily the e-mail client (Windows Mail). Most providers have a limit on the size of attachments to email like 1.5 MB or more. Very large files should be transferred using FTP or a service like the whale Mail or similar.

  • How can we increase the free memory space for application requiring more memory on OS 64 - bit Windows 7 Professional?

    How can you increase storage space free for a request that need more than 2 GB of memory on a 64 - bit Windows 7 professional OS?

    I guess it's a 32-bit application; a 64-bit application would have a 8 TB virtual address space.

    A 32-bit application can be given to a 4 GB virtual address space if it is marked with the IMAGE_FILE_LARGE_ADDRESS_AWARE flag. This is usually accomplished in conjunction with the indicator of this option .

  • Graphic performance rating: How can I increase this score?

    original title: graphical performance evaluation?

    When I try to improve my score on performance monitor, all scores are above 3.0 accept graphics. How can I increase this score?

    Hello Curtis19,

    Witht Windows Experience Index the 'weak link' is still the material with the lowest number. The only option you really increase the WEI of the link must replace this piece of hardware with a better version. In a Word, it means buy a better video card. That's fine with a PC that contains a dedicated or has a spare graphics port graphics card, but if you happen to have a PC with an integrated card (one that is permanently attached to the motherboard (as in a laptop for example and some desktop pc), then it is not so easy, or, in some cases even possible.)

    If you have a laptop, then, because of compact space, the graphics card will be integrated and you will be not Basel upgrade - well not without having to buy a new laptop. If you have a desktop computer and has integrated graphics, you'll find dedicated usually there also a spare graphics port that allows you to insert a graphics card in the slot. In this case, you can improve the IFE by simply buying a better graphics card. However, do not expect miracles, a new graphics card can increae still than the IFE by 1 point or two.

    Personally, I think that the WEI is only a tool of "sale". After all, if the seller tells you that this system has a 3 WEI, but for an extra £50 you can have the system B with a WRI to 4.3 then you, psychologically, will say "well I much prefer system B" is however, System B will be able to do more than to A system? The answer is usually no. If a machine does everything you want it to then do a low WEI would be the least of my worries. As long as the machine runs on my apps, play any video, that I want to watch without slowing down or pixellating then it is good for me.

    I have an iPhone 6 and use Verizon as my server. How can I increase the number of rings until it go to voicemail?

    You can not. There is no adjustment to make on a phone. In fact, it is not based on the number of rings, it is a problem of synchronization based on the parameters of the call. You can contact Verizon to see if they can increase at that time here, but even if they can, it won't be much, only a few seconds if they do at all.
