Im using a very simple script to make an object get smaller over time

#pragma strict

function Update()
{
	transform.localScale -= Vector3(0.002,0.002,0.002); // Reduce object size by .002 per frame
}

Now think of it like iron ore being mined, eventually the object will reach scale 0 once its all been mined. It’s at this point I want the reduce scaling to stop. (at the moment it goes into negative figures and grows again)

How can I set the object(objects scale) a value or percentage? I don’t want it to reach less than zero, better still be able to stop it at about 2% of the original size.

Do I have to assine an INT/Float value to each of the vector3 x,y,z co-ordinates (and if so… how?)

Or is there a more efficient way to do this?

The script so far now is-

#pragma strict

var beingMined : boolean = false;

function Update()
{
	if(beingMined == true)
	{
		transform.localScale -= Vector3(0.002,0.002,0.002); // Reduce object size by .002 per frame
	}
}

As usual any help/suggestions is greatly appreciated.

One possible way is to do this:

#pragma strict
  
  var beingMined : boolean = false;
  
  function Update()
  {
      if(beingMined == true)
      {
         // Check if the local scale of the object is greater than zero on all axes. And if yes, then only decrement
         if(transform.localScale.x > 0 && transform.localScale.y > 0 && transform.localScale.z > 0 )
         {
             transform.localScale -= Vector3(0.002,0.002,0.002); // Reduce object size by .002 per frame
         }    
		 
		 // This check makes sure that the scale does not reach below zero
		 if(transform.localScale.x < 0 && transform.localScale.y < 0 && transform.localScale.z < 0 )
         {
             transform.localScale = Vector3.zero; 
         }  
		 
      }
  }
