FlashDevelop: Unable to start java.exe: The system cannot find the file specified

1. Find the jvm.config file in /flex_sdk/bin/
2. Set java.home= to point to the Java Virtual Machine directory. For example: C:\Program Files\Java\jre1.6.0_06\bin
3. Restart all applications.

to do

accessibility
key listener
full screen
flash vars
swc files
dissapearing text (set text format, make text field bigger, make sure font embeded)

?: conditional Operator

expression1 ? expression2 : expression3

Evaluates expression1, and if the value of expression1 is true, the result is the value of expression2; otherwise the result is the value of expression3.

getters and setters

public class Database {

    private var _test:Number = 666

    public function get test():Number {
        return _test
    }

    public function set test(n:Number):void{
        _test = n
    }
}

    public Main() {
        var databse:Database = new Database()
        trace(databse.test)

        trace(databse.test)
    }
}

setting up flashdevelop

change colour of a movieclip

var colorTransform:ColorTransform = myMC.transform.colorTransform;
colorTransform.color = 0xFF0000;
myMC.transform.colorTransform = colorTransform;

dynamic fonts

1. Add a new font to the Library.
2. Give it a Name and export for ActionScript.
3. If you want a Bold or Italic font set it as so in the Style drop down.
4. Add the following code:

var myFont = new FontClassName();

var myTextFormat = new TextFormat()
myTextFormat.font = myFont.fontName

var myTextField = new TextField()
myTextField.embedFonts = true
myTextField.text = ""
myTextField.defaultTextFormat = myTextFormat
addChild(myTextField)

5. You can also set the text format like this:

myTextField.setTextFormat(myTextFormat)

bitmap copy with blur

var offsetMatrix:Matrix = new Matrix();
offsetMatrix.translate(toCopy.x, toCopy.y);

var bmd:BitmapData = new BitmapData(toCopy.width, toCopy.height);
bmd.draw(toCopy, offsetMatrix);

bitmap = new Bitmap(bmd);
addChild(bitmap);

var filter:BitmapFilter = new BlurFilter(8, 8, BitmapFilterQuality.HIGH)
bitmap.filters = [filter]

greyscale a movieclip

myMovie.filters = [ new ColorMatrixFilter(getSaturationMatrix(0) ]

private function getSaturationMatrix(value:Number):Array {
   
    var nRed:Number = 0.3086; 
    var nGreen:Number = 0.6094;
    var nBlue:Number = 0.0820;
    var nA:Number = (1 - value) * nRed + value;
    var nB:Number = (1 - value) * nGreen; 
    var nC:Number = (1 - value) * nBlue;
    var nD:Number = (1 - value) * nRed;
    var nE:Number = (1 - value) * nGreen + value;
    var nF:Number = (1 - value) * nBlue;
    var nG:Number = (1 - value) * nRed;
    var nH:Number = (1 - value) * nGreen;
    var nI:Number = (1 - value) * nBlue + value;
   
    return [nA, nB, nC, 0, 0, nD, nE, nF, 0, 0, nG, nH, nI, 0, 0, 0, 0, 0, 1, 0];
}

To turn off the greyscale:

myMovie.filters = [ ]

simplest loader

var loader:Loader = new Loader()
addChild(loader)
loader.load( new URLRequest("myFolder/myFile.jpg") )

shuffle an array

var total_questions:int = 10
var temp:Array = new Array()
var random_order:Array = new Array() 

for (var i:int; i < total_questions; i++) {
    temp.push(i)
}

while (temp.length > 0) {
    var r:int = Math.floor(Math.random() * temp.length)
    random_order.push(temp[r])
    temp.splice(r, 1)
}
