Need help scripting "fallout"

I am very new to scripting games and I need help getting my character to die when he falls of the edge I have tried just importing the scripts from Unity's tutorial but it wont work I really need help.

Hi Tracey P,

For the fallout block, make sure that it is a trigger. After that, make sure that it is tagged "fallout" (minus the "") or whatever you want the tag to be.

Then in your character script put:

    function OnTriggerEnter(hit : Collider)
{
    if(hit.gameObject.tag == "fallout")
    {
        dead = true;      // put your death script here
        HealthControl.LIVES -= 1  // subtract health here unless your death script takes care of that.

    }
}

if you are following the TornadoTwins youtube videos, then put that in the MoveAround.js file.
