How do I set a default target?

You can most certainly do this via code, but to give a more specific answer you should post some of your code.

var Distance; var Target : Transform; var lookAtDistance = 25.0; var chaseRange = 15.0; var attackRange = 1.5; var moveSpeed = 5.0; var Damping = 6.0;

var theDammage = 5;

var attackRepeatTime = 1; private var attackTime : float;

var Controller : CharacterController; var Gravity : float = 20; private var $$anonymous$$oveDurection : Vector3 = Vector3.zero;

function Start() { target = GameObject.Find("player"); attackTime = Time.time; Debug.Log("Start function has been run!"); }

function Update () {

 if (Respawn$$anonymous$$enu.playerIsDead == false)
     {
         Distance = Vector3.Distance(Target.position, transform.position);

         if (Distance < lookAtDistance)
         {
         lookAt();
         } 
         
         if (Distance > lookAtDistance)
         {
             renderer.material.color = Color.green;
         }
         
         if (Distance < attackRange)
         {
         attack();
         }
         else if(Distance < chaseRange)
         {
             chase();
         }
         

// if (Target != "player") // { // target = GameObject.Find("player"); // } } }

function lookAt() { renderer.material.color = Color.yellow; var rotation = Quaternion.LookRotation(Target.position - transform.position); transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * Damping); }

function chase() { renderer.material.color = Color.red;

 moveDirection = transform.forward;
 moveDirection *= moveSpeed;
 
 moveDirection.y -= Gravity * Time.deltaTime;
 Controller.$$anonymous$$ove(moveDirection * Time.deltaTime);

}

function attack() { if (Time.time > attackTime) { Target.Send$$anonymous$$essage("ApplyDammage", theDammage, Send$$anonymous$$essageOptions.DontRequireReceiver); Debug.Log("The enemy has attacked"); attackTime = Time.time + attackRepeatTime; } }

function ApplyDammage() { chaseRange += 30; moveSpeed +=2; lookAtDistance += 40; }
