Hey! Im working on my game and i want to make the pick deletes the block by decreasing the number so heres the script that ive been working on.

var PickAxe : GameObject; 
var range : float = Mathf.Infinity; 
var hit : RaycastHit; 
var BlockStrength = 9;

function Update () 
{ 
if(Input.GetButton("Fire1")){ 
} 

if (Input.GetMouseButtonDown(1)) Erase(); 
} 


function Erase() 
{ 

BlockStrength --;
if (BlockStrength == 0)
if(HitBlock()) 
Destroy(hit.transform.gameObject);
} 


function HitBlock() : boolean 
{ 
return Physics.Raycast(transform.position, transform.forward, hit, range); 
}

When i test it works! but it minus the number and minus until infinity.
Is there any ways to fix this from minus?

BlockStrength = Mathf.clamp(BlockStrength, 0, int.MaxValue); will limit the block strength between 0 and 2.147 billion
