Äh... so in etwa meine ich das:


function PolygonClass (stageMC, pointsArray) {
  points = pointsArray;
  stage = stageMC;
}

p = PolygonClass.prototype;

p.draw = function (lineStyle, fill) { // draw as usual
  stage.lineStyle(lineStyle);
  stage.beginFill(fill);
  for (var i=0; i<points.length; i++) {
    stage.moveTo( points[i].x, points[i].y );
  }
  stage.moveTo( points[0].x, points[0].y );
  stage.endFill();
}

p.drawAnimated () { // draw one line per frame
  framePos = 0;
  stage.onEnterFrame = function () {
    listener.onE();
  };
  stage.listener = this;
}

p.onE = function () {
  stage.clear();

  if (framePos++ == points.length) {
    this.draw();
    stage.listener = undefined;
  } else {
    stage.lineStyle(lineStyle);
    for (var i=0; i<framePos; i++) {
      stage.moveTo( points[i].x, points[i].y );
    }
  }
};

delete p;


HTH,
