c# - Unity 5 moving planets in a circular or elliptical path (orbits) -


i have:

void update () {     transform.rotatearound(transform.parent.position, new vector3(0, 1, 0), orbitspeed * time.deltatime); }

which gives me basic circular orbit.

what need varied elliptical orbits (planets generated randomly per star , give them random orbit paths)?

you can't use rotatearound. have make own function

try use:

http://answers.unity3d.com/questions/133373/moving-object-in-a-ellipse-motion.html

x, y: center of ellipse a, b: semimajor , semiminor axes

the code:

 var : int;  var b : int;  var x: int;   var y : int;  var alpha : int;  var x : int;  var y : int;   function update () {      alpha += 10;      x = x + (a * mathf.cos(alpha*.005));      y= y + (b * mathf.sin(alpha*.005));      this.gameobject.transform.position = vector3(x,0,y);  }

edit:

if want orbit object use:

     this.gameobject.transform.position = anotherobject.transform.position + vector3(x,0,y);

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
