Convert Timeline Code to Document Class

By Zevan | August 6, 2009

For a few different reasons I decided to write some php code to convert timeline code to a document class. The script is done and it seems to work pretty nicely. I’m sure there are a few bugs, but I’ve tested around 30 snippets from this site and they all worked.

To test it out:

1) just take the below code (or any other timeline code), copy it to your clipboard
(The code doesn’t have to be small, I did a test with 300 lines of timeline code and it worked just fine)

x = stage.stageWidth / 2;
y = stage.stageHeight / 2;
var xp:Number = 0, yp:Number = 0;
var r:Number = 0, t:Number = 0;
var speed:Number = .07;
var scale:Number = 20;
var plot0:Shape = Shape(addChild(new Shape()));
var plot1:Shape = Shape(addChild(new Shape()));
plot0.graphics.lineStyle(0,0x000000);
plot1.graphics.lineStyle(0,0x000000);
addEventListener(Event.ENTER_FRAME, onLoop);
function onLoop(evt:Event):void {
	 r =  scale * Math.sqrt(t);
	 xp =  r * Math.cos(t);
	 yp =  r * Math.sin(t);
	 t += speed;
	plot0.graphics.lineTo(xp, yp);
	plot1.graphics.lineTo(-xp, -yp);
}

2) go to this page and follow the instructions:
http://actionsnippet.com/timeline_to_doc.php

I used this script to convert a few snippets from this site to work on wonderfl.net…

Have a look at them here.

In the next few days I may add a button to all code snippets that allows you to convert the code to a doc class…

The script adds import statements automatically, I may however have missed a few packages, so if the generated code is missing an import statement, let me know and I’ll fix it…

  57.                 coords += word + " ";
  58.             }
  59.         }
  60.     }
  61. }

This snippet does a twitter search and sorts the results alphabetically. It then reads through the results 3 characters at a time - each set of 3 characters is converted to base32 and then used a y coordinate on a plot.

In order for the swf to be worth looking at, I think I'd need to add an input field. I may do that later... but for now here are a few stills:

ActionSnippet Twitter

By Zevan | August 4, 2009

I guess it's just weird for me to do twitter search api experiments and not have an account that I use... so...

This snippet draws a texture using a twitter search for the word "alphabet". The results are arranged alphabetically and used to draw a texture.


Have a look at the swf:
