Re: [Flashcoders] urgent angle problem

2008-02-05 Thread Glen Pike 

Hi,

You make both values absolute and calculate your angle, then 
subtract 90 from the degrees.


   You have to detect whether adj  is negative and if so, add 180 to 
your angle or something similar if I remember...


var adjside:Number = watchX - originX;
   var oppside:Number = -1*(watchY - originY);
   var angle:Number = Math.atan2(Math.abs(oppside), Math.abs(adjside)); 
// in radians
   var angle:Number = Math.round(angle/Math.PI*180) - 90; // convert to 
degrees
  
   if(0 > adside) {

  angle += 180;
   }

   var angle:Number = -1*(angle); // invert
