Actionscript:

// draw red circle

with (graphics) beginFill(0xFF0000), drawCircle(200,100,30);

 

// draw 100 gray circles

with (graphics) for (var i:int = 0; i<100; i++) beginFill(0x666666), drawCircle(Math.random()*200, Math.random()*200, Math.random()*10), endFill();

 

// draw a few lines

with (graphics) lineStyle(0, 0x000000), moveTo(10,210), lineTo(20,300), lineTo(30,210), lineTo(40,300), lineTo(50,210), lineTo(60,300);

Sometimes it's tedious to write lines and lines of Graphics class method calls. Using a with [...]

Click Listener

By Zevan | November 5, 2008

CLICK HERE TO COPY
Actionscript:

var e:String = "addEventListener";

 

stage[e]("click", function():void{

    trace("clicked", arguments[0]);

});

Strange code to do a click listener. arguments[0] is the event object. (Check out the "warning" page for more info about this).
CLICK HERE TO COPY
Actionscript:

stage.addEventListener(MouseEvent.CLICK, onStageClick);

function onStageClick(evt:MouseEvent):void {

    trace("clicked", evt);

}

Normal way.

for (var i:int = 0; i<map.length; i++){

    for (var j:int = 0; j<map[i].length; j++){

        graphics.beginFill(col[map[i][j]]);
