怎么计算两个点之间的距离

cuixueying

var p1:Point = new Point(10,20); 
            var p2:Point = new Point(100,200); 
            var x:int = p1.x - p2.x; 
            var y:int = p1.y = p2.y; 
            var length:Number = Math.sqrt(Math.pow(x,2)+Math.pow(y,2)); 
            trace(length);

var point = new laya.maths.Point(100,100);
var distance = point.distance(200,200);
console.log('距离: '+distance);
