Collision Tutorial & Destroying Tutorial

Attach to your Character.

function OnCollisionEnter(Col : Collision){
  if(Col.gameObject.name == "enemy"){
    Destroy(gameObject.find("enemy"));
    }
}

You can drag your model to the scene and add a box or sphere collider to it (menu Component/Physics/…). Adjust its dimensions, set Is Trigger in the Inspector and attach an OnTriggerEnter code to it:

function OnTriggerEnter(other: Collider){
  if (other.tag == "Player"){ // check if it's the player, if you want
    Destroy(other.gameObject);
  }
}

Enemy attack the player and death my player send me script sir
