How do I create dynamically text in a movie clip [AS3]? - actionscript-3

I want click on button not text
btn_start.t1.text = "hello world" // not working

Rough code... You will have to work on it but it seems easy.
You just have to set your text for each states of the SimpleButton for each states when you create it.
That's all.
Now you may embed fonts, change the style of your TextField...
var btn_start:SimpleButton = new SimpleButton();
addChild(btn_start);
btn_start.upState = drawUpstate(0xcc5500,"upstate");
btn_start.downState = drawDownstate(0x444444,"downstate");
btn_start.hitTestState = drawDownHitTeststate();
btn_start.overState = drawOverState(0x888888,"overtstate");
addChild(btn_start);
placeButton(btn_start,50,50);
function drawUpstate(color:int, btnLabel:String):Sprite {
var btn_color:uint = color;
var mc:Sprite = new Sprite();
var textLabel:Sprite = new Sprite();
var tf : TextField = new TextField();
tf.textColor = 0xffffff;
tf.text = btnLabel;
mc.addChild(tf);
var g:Graphics = mc.graphics;
drawButton(g,btn_color);
return mc;
}
function drawDownstate(color:int, btnLabel:String):Sprite {
var btn_color:uint = color;
var mc:Sprite = new Sprite();
var textLabel:Sprite = new Sprite();
var tf : TextField = new TextField();
tf.textColor = 0xffffff;
tf.text = btnLabel;
mc.addChild(tf);
var g:Graphics = mc.graphics;
drawButton(g,btn_color);
return mc;
};
function drawDownHitTeststate():Sprite {
var btn_color:uint = 0x0000000;
var mc:Sprite = new Sprite();
var g:Graphics = mc.graphics;
drawButton(g,btn_color);
return mc;
};
function drawOverState(color:int, btnLabel:String):Sprite {
var btn_color:uint = color;
var mc:Sprite = new Sprite();
var textLabel:Sprite = new Sprite();
var tf : TextField = new TextField();
tf.textColor = 0xffffff;
tf.text = btnLabel;
mc.addChild(tf);
var g:Graphics = mc.graphics;
drawButton(g,btn_color);
return mc;
};
function drawButton(g:Graphics,color:uint) {
g.beginFill(color,1);
g.drawRect(0,0,100,20);
g.endFill();
};
function placeButton(btn:SimpleButton,x:uint,y:uint):void {
btn.x = x;
btn.y = y;
};
Best regards.

distortion in textField

I have a bitmap data which draw a text field. after scaling, text are distortion.
I using following code:
// tf is text Field and bm is bitmap.
var tf:TextField = new TextField();
tf.text = "Hello world";
var bd:BitmapData = new BitmapData(200, 200, true, 0x00ff00);
bd.draw(tf);
var bm:Bitmap = new Bitmap(bd);
addChild(bm);
bm.scaleX = 2;
bm.scaleY = 2;
Please guide me.
You should use transform matrix to draw an upscaled text field (or any other vector graphics object) onto a BitmapData.
var mat:Matrix=new Matrix();
mat.scale(2.0,2.0);
bd.draw(tf,mat);
First, increase the font size and then convert and scale as bitmap like so,
//---- Text format ----
var textFormat:TextFormat = new TextFormat();
textFormat.font = "Arial";
//textFormat.bold = true;
textFormat.size = 40;
//---------------------------------------------
//
var tf:TextField = new TextField();
tf.text = "Hello world";
/*tf.antiAliasType = AntiAliasType.ADVANCED;
tf.gridFitType = GridFitType.PIXEL;
tf.thickness = 0;
tf.sharpness = 0;*/
tf.setTextFormat(textFormat);
//
//
var bd:BitmapData = new BitmapData(200,200,true,0x00ff00);
bd.draw(tf);
var bm:Bitmap = new Bitmap(bd);
bm.smoothing = true;
addChild(bm);
bm.scaleX = 2;
bm.scaleY = 2;
Best luck.

Actionscript 3: Soundspectrum animation playing but sound muted. Is this possible?

Kinda of an oxy-moron question but I thought I would go ahead and ask anyhow.... I am looking for my soundspectrum animation to play but my sound will be muted...This will be inserted in a banner ad, so their are specific rsestrictrictions with vendors where the sound has to be user initiated...
Any ideas would be appreciated...
var SpectrumLineWidth:Number;
var SpectrumLineColor:Number;
var SpectrumGlowDirection:String;
var SGD:String;
var ss:ByteArray = new ByteArray();
var bmpData:BitmapData;
var bmp:Bitmap;
var lsp:Sprite = new Sprite();
var blur:BlurFilter;
// Main sounds object
var _sound:Sound = new Sound();
var _soundChannel:SoundChannel;
var _soundTransform:SoundTransform=new SoundTransform(1);
var _soundLoaderContext:SoundLoaderContext = new SoundLoaderContext();
bmpData = new BitmapData(10,10,true,0xcccccc);
bmp = new Bitmap(bmpData);
spectrumArea.specArea.addChild(lsp);
spectrumArea.specArea.addChild(bmp);
// filter;
blur = new BlurFilter(8,8,4);
// save configuration
SpectrumLineWidth = 1;
SpectrumLineColor = 0x0066FF;
var s:Sound = new Sound();
//s.setVolume(0);
var sc:SoundChannel;
var ba:ByteArray = new ByteArray();
var array:Array;
s.load(new URLRequest("test.mp3"));
sc = s.play(0,1000);
sc.soundTransform = _soundTransform;
this.addEventListener(Event.ENTER_FRAME, spectrum);
function spectrum(event:Event){
lsp.graphics.clear();
lsp.graphics.lineStyle(SpectrumLineWidth, SpectrumLineColor);
lsp.graphics.moveTo(-1, 50);
SoundMixer.computeSpectrum(ss);
for (var i:uint = 0; i<350; i++)
{
var num:Number = - ss.readFloat() * 50 + 50;
lsp.graphics.lineTo(i, num);
}
bmpData.draw(lsp);
bmpData.applyFilter(bmpData, bmpData.rect,new Point(), blur);
//SGD = SpectrumGlowDirection;
//lsp.graphics.clear();
//lsp.alpha=.5
bmpData.draw(lsp);
}
//var sd:SoundTransform = new SoundTransform();
//sd.volume=0;
//SoundMixer.soundTransform = new SoundTransform(1);
You cant do it with SoundMixer.computeSpectrum(ss);
Look into Sound.extract

Actionscript 3 - DataGridColumn and having a specific column automatically sorted

I am using the DataGrid component in Flash, that is loaded with data via a external XML file. I have a column, A (Serial), which once loaded, I'd like for the information to be sorted Ascendingly, automatically. Does anyone have any idea on how to do this?
Here is my code:
import fl.controls.DataGrid;
import fl.data.DataProvider;
import fl.controls.dataGridClasses.DataGridColumn;
import fl.controls.ScrollPolicy;
import fl.events.DataGridEvent;
var dp:DataProvider;
var A:DataGridColumn = new DataGridColumn("Serial");
A.headerText = "Serial No.";
A.width = 100;
A.resizable = false;
var B:DataGridColumn = new DataGridColumn("Mold");
B.headerText = "Mold No.";
B.width = 150;
B.resizable = false;
var C:DataGridColumn = new DataGridColumn("Type");
C.headerText = "Grid Type: ";
C.width = 350;
C.resizable = false;
var myDataGrid:DataGrid = new DataGrid();
myDataGrid.addColumn(A);
myDataGrid.addColumn(B);
myDataGrid.addColumn(C);
myDataGrid.verticalScrollPolicy = ScrollPolicy.ON;
myDataGrid.setSize(600, 800);
myDataGrid.move(0, 0);
myDataGrid.addEventListener(DataGridEvent.HEADER_RELEASE, headerReleaseHandler);
addChild(myDataGrid);
var url:String = "xml/TEST.xml";
var req:URLRequest = new URLRequest(url);
var uLdr:URLLoader = new URLLoader();
uLdr.addEventListener(Event.COMPLETE, completeHandler);
uLdr.load(req);
function completeHandler(event:Event):void {
var ldr:URLLoader = event.currentTarget as URLLoader;
var xmlDP:XML = new XML(ldr.data);
dp = new DataProvider(xmlDP);
myDataGrid.dataProvider = dp;
}
function headerReleaseHandler(event:DataGridEvent):void {
var dg:DataGrid = event.currentTarget as DataGrid;
trace("column: " + String(event.dataField));
trace("descending: " + String(dg.sortDescending));
}
Thanx
Try the sortItemsOn() method on the DataGrid.
See http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/fl/controls/SelectableList.html#sortItemsOn() for an example how to use it.

AS3 - Remove Child Problem

I'm using the following code to display an advertisement in a mobile game that I'm working on. It works fine but I don't know what to put in the clickStart function to remove the advertisement from the stage before the game plays. I've been playing around with removeChild but can't seem to get it to work.
stop();
startButton.addEventListener(MouseEvent.CLICK,clickStart);
function clickStart(event:MouseEvent) {
gotoAndStop("play");
}
var request:URLRequest = new URLRequest("http://soma.smaato.com/oapi/reqAd.jsp");
var variables:URLVariables = new URLVariables();
variables.adspace = "0";
variables.pub = "0";
variables.devip = "127.0.0.1";
variables.format = "IMG";
variables.adcount = "1";
variables.response = "XML";
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(request);
function onComplete(e:Event):void
{
var data:XML = new XML(loader.data as String);
var status:String = data.*::status.toString();
if(status == "success")
{
var ad:XMLList = data.*::ads.*::ad;
var link:String = ad.*::link.toString();
var l:Loader = new Loader();
l.load(new URLRequest(link));
addChild(l);
l.x = 135;
l.y = 265;
var clickurl:String = ad.*::action.#target.toString();
l.addEventListener(MouseEvent.CLICK, onAdClick);
function onAdClick(e:MouseEvent):void
{
var request:URLRequest = new URLRequest(clickurl);
navigateToURL(request);
}
}
}
You need to move the declaration of the Loader outside of the onComplete function, since the variable runs out of scope.
var l:Loader = new Loader();
You could try placing it on the same scope as these:
var request:URLRequest = new URLRequest("http://soma.smaato.com/oapi/reqAd.jsp");
var variables:URLVariables = new URLVariables();
then you should be able to update your clickStart function to something like this:
function clickStart(event:MouseEvent) {
removeChild(l);
gotoAndStop("play");
}

AS3 - positon advertisment that is dynamically loaded

I'm using the code below to place an ad inside a mobile game that I'm building. My problem is that the ad appears in the top left corner of the stage and I need to be able to move it centered near the bottom. I got this code from a book and I understand about 70% of what it's doing. Thanks for any direction you can offer.

// Smaato Advertising Code for Start Screen

The problem is that you are never actually positioning the image, so the default is [0,0], the top-left corner of the screen.
var request:URLRequest = new URLRequest("http://soma.smaato.com/oapi/reqAd.jsp");
var variables:URLVariables = new URLVariables();
variables.adspace = "0";
variables.pub = "0";
variables.devip = "127.0.0.1";
variables.format = "IMG";
variables.adcount = "1";
variables.response = "XML";
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(request);
function onComplete(e:Event):void
{
var data:XML = new XML(loader.data as String);
var status:String = data.*::status.toString();
if(status == "success")
{
var ad:XMLList = data.*::ads.*::ad;
var link:String = ad.*::link.toString();
var l:Loader = new Loader();
l.load(new URLRequest(link));
l.contentLoaderInfo.addEventListener(Event.COMPLETE, onAdLoaded);
function onAdLoaded(e:Event):void
{
var ad:DisplayObject = e.target.content;
addChild(ad);
ad.x = (ad.stage.stageWidth - ad.width) / 2;
ad.y = (ad.stage.stageHeight - ad.height) / 2 + 50;
}
var clickurl:String = ad.*::action.#target.toString();
l.addEventListener(MouseEvent.CLICK, onAdClick);
function onAdClick(e:MouseEvent):void
{
var request:URLRequest = new URLRequest(clickurl);
navigateToURL(request);
}
}
}
That will center the loaded file. The 50 number is because if you don't want it to be in the exact center, you can use the number to adjust the y-value accordingly.
By the way, I recommend you to grab another book, becase the code you are using seems a bit old and have poor performance.
If you have any other issue regarding this, comment it and I can expand my answer.
