Wieso funktioniert der Spider Script nicht unter Flash 7?

[Nophytex]

Der da geht so:

onClipEvent (load) {
	var go = true; // if this var is false, the spider will not move on it's own
	myBounds = _root.boundbox.getBounds(_root);
	var maxspeed = 15; // maximum walking speed
	var friction = 0.96;
	var d = 2;
	var a = 4;
	var n = 1;
	var legn = 1;
	var lega = 2;
	var legd = 2.7;
	// these next 2 lines put the body on top of the lines (just a cosmetic change)
	duplicateMovieClip ("oldbody", "body", 100);
	oldbody._visible = false;
}
onClipEvent (enterFrame) {
	// life code start
	if (go) {
	var change = random(30)+1; // this determines whether he will change direction/speed
	if (change == 5) { //if change is 5, then change the speed/direction of the spider
		var xspeed = (random(maxspeed)+1)-((maxspeed-1)/2);
		var yspeed = (random(maxspeed)+1)-((maxspeed-1)/2);
	}	
	xspeed *= friction;
	yspeed *= friction;
	var newypos = body.char0._y+yspeed;
	var newxpos = body.char0._x+xspeed;
	// check the boundaries
	if (newypos>(myBounds.yMax-_y)) {
		yspeed = -8;
	}
	if (newypos<(myBounds.yMin-_y)) {
		yspeed = 8;
	}
	if (newxpos>(myBounds.xMax-_x)) {
		xspeed = -8;
	}
	if (newxpos<(myBounds.xMin-_x)) {
		xspeed = 8;
	}
	// end bounds check
	body.char0._y = newypos;
	body.char0._x = newxpos;
	} // end life code
	for (i=1; i<=8; i++) {
		// draw the legs
		attachMovie("line", "line"+i, i);
		var myToe = this["toe"+i];
		var myLeg = this["line"+i];
		myLeg._x = body.char1._x;
		myLeg._y = body.char1._y;
		myLeg._xscale = (myToe.char1._x+myToe._x)-body.char1._x;
		myLeg._yscale = (myToe.char1._y+myToe._y)-body.char1._y;
		// end legs
		// move the toes
		var walkdist = random(60)+45;
		xlegdist = Math.abs(myToe.char1._x-body.char1._x);
		ylegdist = Math.abs(myToe.char1._y-body.char1._y);
		if (xlegdist>walkdist || ylegdist>walkdist) {
			walktoX = random(walkdist)-(walkdist/2);
			walktoY = random(walkdist)-(walkdist/2);
			myToe.char0._x = body.char1._x+(walktoX*1.5);
			myToe.char0._y = body.char1._y+(walktoY*1.5);
		}
	}
}

Hallo kann mal einer das Flash checken, dürfte noch aus Flash 5 Zeiten stammen, soll aber jetzt unter Flash 7 laufen.

Handelt sich um dieses Spinnen Script, wo sone Spinne rumläuft.
Kann euch auch gerne die Fla schicken,wenns auch weiterhilft, aber das sollte das ganze wichtige AS gewesen sein!!
