Here is senoculars TV Static converted to AS3

import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.BitmapDataChannel;

// create a new movie clip for the static
var static_mc:MovieClip = new MovieClip();

this.addChild(static_mc);

// position the static movie clip with the mask
static_mc.x = mask_mc.x;
static_mc.y = mask_mc.y;

// create a bitmap data instance the size of the mask
// that will be used to draw static in
var _bitmapData = new BitmapData(mask_mc.width, mask_mc.height);
var _bitmap = new Bitmap(_bitmapData)

// attach the bitmap to the static movie clip
static_mc.addChild(_bitmap);

// apply the mask
static_mc.mask = mask_mc;

static_mc.addEventListener(Event.ENTER_FRAME, _static);

// every frame draw static
function _static(e:Event):void

var seed:int = int(Math.random() * int.MAX_VALUE);
_bitmapData.noise(seed, 0, 0xFFFFFF, BitmapDataChannel.RED, true);
}

I tried using this static file but couldn't figure out how to put anything on top of it. Any ideas?

[rai_kane3]

could you give me a little more about what your wanting to do?

at a guess you could place the code inside a mc, and create a new layer above and add what you want on that layer but thats a guess.

Ya that worked thanks!

[rai_kane3]

no problem

Hey rai_kane3

Is there any way to make the boxes any bigger? Thanks!

I have the same problem.

The static size is based on the size of the mask, increase the mask and the static should fill the mask area


so e.g

mask_mc.width = 300;
mask_mc.height = 200;

as for adding something ontop of the static if you read the previous post you can place this code inside a movieclip on the stage and place your content on a new layer above.

alternativly if you wanted to code it instead try this.

create a new movieClip in the library and give is a class name of Content.

please any text images or anything else you want in here.

to increase the static size just set the maskers graphic.draw to a what ever with or size you want




import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.BitmapDataChannel;

// create a new movie clip for the static

var static_mc:MovieClip = new MovieClip();
var container:MovieClip = new MovieClip();
var _content:Content = new Content();
var masker:Sprite = new Sprite();
var padding:Number = 10;

masker.graphics.beginFill(0x0000FF);
// set the width of the mask
masker.graphics.drawRect(0,0,250,100);
masker.graphics.endFill();

addChild(container);
addChild(_content);

container.addChild(masker);
container.addChild(static_mc);

// Container is placed in the center
container.x = stage.stageWidth / 2 - container.width / 2;
container.y = stage.stageHeight / 2 - container.height / 2;

// content matches container position with padding
_content.x = container.x + padding;
_content.y = container.y + padding;

// position the static movie clip with the mask
static_mc.x = masker.x;
static_mc.y = masker.y;

// create a bitmap data instance the size of the mask
// that will be used to draw static in
var _bitmapData = new BitmapData(masker.width, masker.height);
var _bitmap = new Bitmap(_bitmapData)

// attach the bitmap to the static movie clip
static_mc.addChild(_bitmap);

// apply the mask
static_mc.mask = masker;

static_mc.addEventListener(Event.ENTER_FRAME, _static);

// every frame draw static
function _static(e:Event):void
{
var seed:int = int(Math.random() * int.MAX_VALUE);
_bitmapData.noise(seed, 0, 0xFFFFFF, BitmapDataChannel.RED, true);
}

I'm completely new to AS3.0 and partly new to Flash itself, so could someone please describe in detail how to add a shape (say a circle) on top of static? I don't particularly care about the TV. I tried all your methods in various combinations in CS4 Professional but they don't seem to work.

Any help would be greatly appreciated.

// draw red circle with 100 pixel radius
var circle:Shape = new Shape();
var g:Graphics = circle.graphics;
g.beginFill(0xFF0000, 1);
g.drawCircle(0,0,100);
g.endFill();

// place circle at center of stage
circle.x = stage.stageWidth/2;
circle.y = stage.stageHeight/2;

// add circle after adding the other content
addChild(container);
addChild(content);
addChild(circle);
