Death zone scripts

The 3D platform game tutorial uses "fall out" zones which sounds like what you're after. You need to specify a spawn point and you need to remove the player model when it enters the death zone. Use a box collider set to trigger and enter something like this:

function OnTriggerEnter (other : Collider) {
  // destroy all game objects that enter this area
  Destroy(other.gameObject);
}

Alternatively you can hide the player character instead of removing it. Then you need to call a respawn function in your player controls script and have a new player created at your spawn point, if the player still exists you just use the translate function to move it back to the spawn point:

transform.position = respawnPosition

Hope that helps

I am not sure if you have made an object for the death zone but here is a solution. Make a plane (if you don't have one) where the death zone is. You could add this script to the character.

private var dead = false;

function LateUpdate() { if(dead) { transform.position = Vector3(0,0,0); gameObject.Find("Main Camera").transform.position = Vector3(0,0,0); dead = false; } }

Just tag your death zone whatever you want it to be called and then replace the tag I put in the script ("DEATHZONE") with the tag you made for the death zone. Change the vector 3 part of the script to the spawn point location.
