I've been trying to make something point in another things direction but it's saying unexpected packages then it's saying public funtion is only allowed in a package then access of undefined property then left paren before left brace and so on. here is the code. currently there it's not saying where or what the error is so just take a look:

 

import flash.display;
import flash.events;

class rHit extends MovieClip

{
rHit.addEventListener(Rat);
function Rat();
{
var angle:Number = Math.atan2 (r.Y, r.X);
var degrees:Number = angle * 180/Math.PI;
rHit.rotation = degrees;
trace();
}
}

    Got it.

     

    So don't use class or package keywords/structure because they are reserved for class files.

     

    I don't know exactly what you were trying to achieve, so I coded a generic "rotate to target" example.

     

    AS3 code:

    import flash.events.Event;
import flash.events.MouseEvent;

function enterFrameHandler(e:Event):void
{
	var angle: Number = Math.atan2(target.y - arrow.y, target.x - arrow.x);
	var degrees: Number = angle * 180 / Math.PI;
	
	arrow.rotation = degrees;
}

function mouseDownHandler(e:MouseEvent):void
{
	arrow.startDrag();
}

function mouseUpHandler(e:MouseEvent):void
{
	stopDrag();
}

stage.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
stage.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);

     

    Please notice that the arrow artwork must be facing to the right because that's the 0 degree in Flash/AS3.

     

    FLA / source / code / files:

      Hi.

       

      Are you coding in a frame or a class file?
