ok so i have been trying to detect the mouse angle… kinda figuring it out on my own to learn new stuff and get a better understanding of actionscript, but ive kinda run into a problem i cant figure out.

here is the range of angles i get

```auto

    0
    |      
    |
90-----90
    |
    |
    0

```

here is the range i want

```auto

  90
   |
   |
180-0
   |
   |
  270

```

and finally here is my code

```auto

_root.onLoad = function(){
	var a, b;
	var convert;
	var ang;
}

_root.onEnterFrame = function(){
	xCoord = (_xmouse - 200);
	yCoord = (_ymouse - 200)*-1;
	calcAngle();
	
}

_root.calcAngle = function(){
	a = Math.abs(xCoord);
	b = Math.abs(yCoord);
	ang = Math.atan(a/b);
	convert = 180/Math.PI;
	mouseAngle = ang*convert;
}

```

any help would be greatly appreciated, thank you

ok… i think im getting what you want…  
try this.  
you should get angles like this o hope 😛 i never had time to test it but iv done some work on this sort of thing before

```
        270
          ^
           |
           |

```

180\<-------\>0  
|  
|  
/  
90

\_root.calcAngle = function(){  
a = Math.abs(xCoord);  
b = Math.abs(yCoord);  
convert = 180/Math.PI;  
mouseAng = Math.atan(b/a)\*convert;  
}

that should work but im not sure :S
