Question by IKilledKenny_2 · Oct 30, 2014 at 09:07 PM · playerraycasting

Auto Target Raycast

Hello Unity3D.I have a question about auto target?How can i make my characters auto target from each other by raycasting from when the round starts?For example i want my character and my opponent character to look at each other automatically as soon as the round starts with raycast(since i read that being the easiest way to auto lock on someone or something.)If anyone knows how to do this.Can you please tell me how i can code it or lend me tips because i have been stuck on this for weeks...

Code Here if anyone needs it

 #pragma strict
 var targetPos : Transform; 
 var lookAtObj : Transform;
 var followSpeed : float = 10;
 var hit : RaycastHit;
 // smooth damp stuff
 
  
 var targetSmoothDamp : float = 0.3;
 var targets: GameObject[];
 private var targetVX : float;
 private  var targetVY : float;
 private var targetVZ : float;
 function Start () {
  
 }
  
 function Update () {
 
 
  if(hit.collider.CompareTag("Player"))
 
  
 transform.position.x = Mathf.SmoothDamp(transform.position.x, targetPos.position.x, targetVX, targetSmoothDamp);
 transform.position.y = Mathf.SmoothDamp(transform.position.y, targetPos.position.y, targetVY, targetSmoothDamp);
 transform.position.z = Mathf.SmoothDamp(transform.position.z, targetPos.position.z, targetVZ, targetSmoothDamp);
 transform.position.y = Mathf.Lerp(transform.position.y, targetPos.position.y, Time.deltaTime * 10);
  
  
 transform.LookAt(lookAtObj);
 }

Hello,

I've read your code and my guess is that you need to "fire" raycast :

 var ray = new Ray(from /* where the raycast starts */, dir /* direction of your raycast */, dist /* distance of that raycast */);

 if(Physics.Raycast(ray, out hit))
 {
     if(hit.collider.CompareTag("Player")) //... your code here

If this answer wouldnt be enough, please ask a question in comment and i'll edit.

Regards, M.Rogalski
