c# - How to make enemies turn and move towards player when near? Unity3D -


i trying make enemy object turn , start moving towards player object when player comes within vicinity.

for turning have been testing transform.lookat() function although isn't returning desired results when player close enemy object enemy starts tilt backwards , want enemy able rotate along y axis, in advance.

using unityengine; using system.collections;  public class enemycontroller : monobehaviour {     public transform visionpoint;     private playercontroller player;      public transform player;      public float visionangle = 30f;     public float visiondistance = 10f;     public float movespeed = 2f;     public float chasedistance = 3f;      private vector3? lastknownplayerposition;     // use initialization     void start () {         player = gameobject.findobjectoftype<playercontroller> ();     }      // update called once per frame     void update () {         // not giving desired results         transform.lookat(player);     }      void fixedupdate () {      }      void () {         vector3 deltatoplayer = player.transform.position - visionpoint.position;         vector3 directiontoplayer = deltatoplayer.normalized;          float dot = vector3.dot (transform.forward, directiontoplayer);          if (dot < 0) {             return;         }          float distancetoplayer = directiontoplayer.magnitude;          if (distancetoplayer > visiondistance)         {             return;         }          float angle = vector3.angle (transform.forward, directiontoplayer);          if(angle > visionangle)         {             return;         }          raycasthit hit;         if(physics.raycast(transform.position, directiontoplayer, out hit, visiondistance))         {             if (hit.collider.gameobject == player.gameobject)             {                 lastknownplayerposition = player.transform.position;             }         }     } }

change @ target:

void update () {     vector3 lookat = player.position;     lookat.y = transform.position.y;     transform.lookat(lookat); }

this way @ target on same height object.

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 .
