Question : Help converting a small AS2 script to AS3

Hi all,

I found some AS2 script i need on the net, problem is I haven't been able to successfully convert it to AS3 (my skills in AS2 are a bit limited)

Any help would be appreciated.

Thanks,

Xavier.

Answer : Help converting a small AS2 script to AS3

solved it myself :)

put this in your frame script

var myLine1:LineSprite = new LineSprite();
var myLine2:LineSprite = new LineSprite();
var myLine3:LineSprite = new LineSprite();
var myLine4:LineSprite = new LineSprite();
var myLine5:LineSprite = new LineSprite();
var myLine6:LineSprite = new LineSprite();

myLine1.initializeLineSprite(1);
myLine2.initializeLineSprite(2);
myLine3.initializeLineSprite(3);
myLine4.initializeLineSprite(4);
myLine5.initializeLineSprite(5);
myLine6.initializeLineSprite(6);

myLine1.addEventListener(Event.ENTER_FRAME,doEvent);
myLine2.addEventListener(Event.ENTER_FRAME,doEvent);
myLine3.addEventListener(Event.ENTER_FRAME,doEvent);
myLine4.addEventListener(Event.ENTER_FRAME,doEvent);
myLine5.addEventListener(Event.ENTER_FRAME,doEvent);
myLine6.addEventListener(Event.ENTER_FRAME,doEvent);

addChild(myLine1);
addChild(myLine2);
addChild(myLine3);
addChild(myLine4);
addChild(myLine5);
addChild(myLine6);

function doEvent(e:Event) {
      //begin with a clean canvas
      e.target.graphics.clear();
      e.target.graphics.lineStyle(e.target.lwidth,0xFFFFFF);
      for (var xx:int = 0; xx < e.target.p; xx++) {
            var r:Number = xx / (e.target.p - 1);
            var px:Number = e.target.sx + r * (e.target.ex - e.target.sx);
            var py:Number = e.target.sy + e.target.wh * Math.sin(r * r * e.target.PI2 + getTimer() * e.target.ws);
            if (xx == 0) {
                  e.target.graphics.moveTo(px, py);
            }
            e.target.graphics.lineTo(px, py);
            //trace("px:"+px+" py:"+py);
            //trace(e.target.ws);
      }
}
