Peepz,

I Have a script to caclulate a full circle placeMent, but i can’t rewrite it to a half circle.
can somebody help me out?


function calcCirlceXY(myArray:Array):Array
{
 var radius:Number = 200;
 var amount:Number = 7;
 
 var x:Number = Stage.width/2;
 var y:Number = Stage.height/2;
 
 var circleRadius:Number = 180
 
 var myArray:Array = new Array()
 
 for (var i:Number = 0; i<amount; i++) 
 {
  var myX:Number =  x+(Math.sin(((circleRadius/amount)*i)*Math.PI/(circleRadius/2))*radius);
  var myY:Number =  y-((Math.cos(((circleRadius/amount)*i)*Math.PI/(circleRadius/2)))*radius);
  
  myArray* = new Array()
  myArray*[0] = myX
  myArray*[1] = myY
 }
  
 return myArray
}
