Vector.<Point>.sortOn()? How to make a compare function?

okay in as2 had array of points. , sorted this: myarray.sorton(["x", "y"],[array.numeric, array.numeric]);

 

i changing code on as3 , thought change array vector of points. realized there isn't sorton method vectors.

 

the sort method takes compare function , think have working. wondering if there better or cleaner way of writing compare functions? new me.

 

 

function compare(p1:point,p2:point):number {

if (p1.x>p2.x || (p1.x==p2.x && p1.y>p2.y)) {

return 1;

} else if (p1.x<p2.x || (p1.x==p2.x && p1.y<p2.y)) {

return -1;

}

return 0;

}

i feel sure using faster vector arrays , doing own sort won't fast using array , doing sorton. also, limit flash player 10, although common now, isn't everywhere player 9 is.

 

your original as2 code works unchanged in as3:

 

var myarray:array = [new point(10,10),new point(10,5),new point(5,33)]

myarray.sorton(["x", "y"],[array.numeric, array.numeric]);

trace(myarray)

 

(x=5, y=33),(x=10, y=5),(x=10, y=10)
