how can calculate displacement of point in jsxgraph. suppose there point @ (0, 0) location. if drag point (0, 0) (2, 0). displacement 2 units. query formula in jsxgraph calculate displacement. if want calculate distance between 2 jsxgraph points, p , q , dist method can used: p.dist(q) if want determine distance point p coordinate array [x, y] , done this: jxg.math.geometry.distance(p.coords.usrcoords, [1, x, y]); instead of [x, y] 1 has use [1, x, y] , because jsxgraph works homogeneous coordinates, allow handle infinite points. a dynamic example this: var p = board.create('point', [3, 0]), q = board.create('point', [0, 0]), t = board.create('text', [1, 1, function() { return p.dist(q); }]);

(so obviously, output should 10). the problem when this, function calls infinitely. list looks this: [[1]] function (x) { x } [[2]] function (x) { functions[[i - 1]](x) + x } [[3]] function (x) { functions[[i - 1]](x) + x } (...) so when call functions[[10]](x) , evaluates functions[[9]](x) + x , functions[[9]] keeps calling on , on again. is there can force r write value of i - 1 each element of list, such follows?

apple has changed swift reflection in xcode 7 beta 5. global reflect() function gone, , you'll have this: let mirror = mirror(reflecting: object) it gives more or less same information in nicer way (no more .1 og .2 propertyname , value). can't find way explore if mirrored item instance of class. older implementation check following: reflectedproperty.1.objectidentifier != nil || reflectedproperty.1.count > 0 but objectidentifier seems gone , count 2 regardless of type. help anyone? ok found workaround. iterating on mirror.children.enumerate() seemed make properties of type string. instead dug apple preliminary documentation, , read idea "upgrade" children e.g. anyrandomaccesscollection. made possible rely on count of objects children determine if it's object (after testing whether it's array) currently have functioning swift class json serializer working here on gist if interested in code: https://gist.github.com/peheje/cc3618253d4
