Yesterday night I wanted to have some “no-purpose coding session” and thought it was a nice idea to record the session and do a speedcoding video. The original video has been collapsed from 45 minutes to 3 minutes circa.
The main concept is once again based on perlinNoise which (I am sure you already guessed) is something I do like very much. So please start call me “The PerlinNoise Guy” or “Perlinator”. 
So this is my first speedcoding video (be sure to look at it in high quality):
Here’s the interactive demo:
Click to launch. Move mouse (x position) to change smoothness (my favourite values are around 100)
The code consist on a Branch.as class file (click to download) and some timeline code to assemble the demo:
import com.oaxoa.fx.Branch; const w:uint=stage.stageWidth; const h:uint=stage.stageHeight; var ct:ColorTransform=new ColorTransform(1,1,1,1,1,1,1); var renderView:BitmapData=new BitmapData(w, h, true); var bmp:Bitmap=new Bitmap(renderView); addChild(bmp); var tf:TextFormat=new TextFormat("_sans", 16, 0, true); var label:TextField=new TextField(); label.width=400; label.defaultTextFormat=tf; addChild(label); var timer:Timer=new Timer(10); timer.addEventListener(TimerEvent.TIMER, ontimer); timer.start(); function ontimer(event:TimerEvent):void { addNew(); } function addNew():void { label.text="Smoothness: "+String(mouseX-w/2); var tt:Branch=new Branch(mouseX-w/2); tt.x=stage.stageWidth/2; tt.y=stage.stageHeight/2; tt.addEventListener(Event.COMPLETE, oncomplete); addChild(tt); renderView.colorTransform(renderView.rect, ct); } function oncomplete(event:Event):void { var t:Branch=event.currentTarget as Branch; var matrix:Matrix=new Matrix(); matrix.translate(t.x, t.y); renderView.draw(t, matrix); removeChild(t); t.removeEventListener(Event.COMPLETE, oncomplete); t=null; }
I didn’t forget about the lightning class part 3 that I will publish soon 
As usual if you liked this drop a line in the comments.
