How to make an enemy teleport?

Questions & Answers
1

I would like to make enemies that has the ability to teleport across the map randomly (while they following you). How exactly would I do that? I already have the character set up to follow the player, so all I need is the teleporting part.

var target : Transform;
var vel_vec : Vector3;
var speed : float;
var distance_byte : float;
var player_life : Player_life_script;

function Update()
{
vel_vec = target.position - transform.position; // creates the vector from the enemy to you.
transform.LookAt(target); // enemy looks to you
transform.Translate(Vector3.forward * speed * Time.deltaTime); // enemy walks to you
if (vel_vec.magnitude <= distance_byte) //if is near
{
animation.Play("byte", PlayMode.StopAll);
player_life.hp -= 1;
vel_vec = Vector3.zero;
}
else if (vel_vec.magnitude > distance_byte + 5) // if is far
animation.Play("walk", PlayMode.StopAll);
}

If they are beyond a certain distance you can teleport or catch them up by setting the enemy/npc position to the player position. Maybe use a random amount away so they don’t spawn right on top of the player.

Get the distance to the other player from the enemy/npc maybe in Update:

float distance = Vector3.Distance (playerObject.transform.position, npcObject.transform.position);

If over a certain amount

if(distance > 20f) {

  Vector3 playerPosRandomized= playerObject.transform.position;
  // randomize x or z
  playerPosRandomized.x = playerPosRandomized.x + UnityEngine.Random.Range(-10f,10f);
  playerPosRandomized.z = playerPosRandomized.z + UnityEngine.Random.Range(-10f,10f);
  npcObject.transform.position = playerPosRandomized;

  // play some effect
}

If you need teleport effects make a particle effect appear or a sprite animation when updating the position.

var close :boolean;

var following:boolean;

function Start(){
   pos[0]=new Vector3(x,y,x);  //Here intead of x,y,z put the appropriate positions
   pos[1]=new Vector3(x,y,x);
   pos[2]=new Vector3(x,y,x);
   pos[3]=new Vector3(x,y,x);
   pos[4]=new Vector3(x,y,x);
   target = GameObject.Find("Player").transform;
}


function Update(){
   if(close){
      following = true;
      vel_vec = target.position - transform.position; // creates the vector from the enemy to you.
      transform.LookAt(target); // enemy looks to you

      }else if (vel_vec.magnitude > distance_byte + 5) // if is far
         animation.Play("walk", PlayMode.StopAll);
    }else

   if(following){   
      timer += Time.deltaTime;

      else if (fadeIn) FadingIn();
   }
}

function FadingOut(){  
   renderer.material.color.a-=Time.deltaTime;    // The NPC slowly disappear
   if(renderer.material.color.a < 0.1){        // If almost gone 
      transform.position = FindClosestTarget();//Here calling function
      fadeOut = false;

   }

    var distance = Mathf.Infinity;  
    for (var i:int = 0; i < 5; i ++ )  { //Iterating through all target and defining the closest to the target/player
        var diff = (target.position - pos*);*

var curDistance = diff.sqrMagnitude;
if (curDistance < distance) {
closest = pos*;*
distance = curDistance;
}
}
return closest;
}
function OnTriggerEnter(other:Collider){
if(other.gameObject.tag == “Player”) close = true;
}
function OnTriggerExit(other:Collider){

}
Ok I added your part of the script. You need to add a sphere collider set to Is Trigger to your alien. When your player steps inside the wone the alien will cahse him. While chasing the following script will trigger until you manage to either kill him or run away out of the sphere zone.You still need to add the part where your alien is wandering around when is not chasing you.

I couldn’t get it to work either, but good luck. And you aren’t trying to recreate Slender are you? :wink: haha
