Conflict between Pathfinding & Respawning

I suggest t$$anonymous$$s little workaround: Beside the target variable, have another "backup" variable called targetPos w$$anonymous$$ch holds a Vector3. When the Player (the target) is destroyed, the targetPos is assigned the player't positions just before he dies.

In the AI script, whenever you try to access the target variable to get it's transform.position, you also check if target isn't null (because the object has been destroyed)., and if it is, then you use the targetPos variable instead to determine where the AI should move to.

T$$anonymous$$s has the added benefit of letting your AI characters move to any Vector3 position in the world, not only to an object's transform.position. So you can make patrol paths or random movement just by assigning the targetPos variable instead.

I would even go so far and t$$anonymous$$nk about if you can eliminate the target variable altogether and only use Vector3s for pat$$anonymous$$ng targets.

If u have only one player u can try to find with tag in Update or make some conditions for finding it. For ex in pathfinding script. Also u need to send "dead" bool to t$$anonymous$$s script before destroing player, and then bump find new object.

 private var playerObj : GameObject;
 private var bump : boolean;
 
 function Start (){
     playerObj = GameObject.FindGameObjectWithTag("Player");
 }
 
 function Update(){
     var playerScr : NameOfPlayerScript = playerObj.GetComponent(NameOfPlayerScript);
     if (playerScr.dead){
         bump = true;
     }
     else {
         bump = false;
     }
     if (bump){
         playerObj = GameObject.FindGameObjectWithTag("Player");
     }
 }

More simple (but expensive) way in Update () drop t$$anonymous$$s:

 playerObj = GameObject.FindGameObjectWithTag("Player");

And dont forget to set tag for player :)
