this is my error MissingFieldException: Field ‘UnityEngine.Vector3.hit’ not found.

Here is the script
var range : float = Mathf.Infinity;
var hit : RaycastHit;
function Update () {
if(Input.GetMouseButtonDown(0)){
Erase();
}
}
function Erase()
{
if(HitBlock())
Destroy(hit.transform.gameObject);
}
function HitBlock() : boolean
{
return Physics.Raycast(transform.postion, transform.forward. hit.range);
}

I believe you are also confused as to how to use Raycast. Look over the documentation about it.

A RaycastHit is a byproduct of Physics.Raycast. It’s result is a boolean. thus returns true or false.
