destroy gameObject when in range?

I made a script for my game, it basically allows you to “Harvest” whatever you put the script on and “drops” what you put into an ItemDrop transform. this is the script

#pragma strict
var itemdrop : Transform;

function Update () 
{
	if(Input.GetMouseButtonDown)
		
		Destroy (gameObject, 5);
	Instantiate(itemdrop, transform.position, Quaternion.identity);
		
}

My only problem is due to the Input.GetMouseButtonDown, the prefab destroys itself as soon as i click play. I need it to only destroy itself when i am in range of it. How would i go about doing this? I would try RayCast but i don’t know how. I prefer Javascript and any help is appreciated

You can do it by checking collisions in OnCollisionEnter(Collision collision) method. [code not tested]:

void OnCollisionEnter(Collision collision) 
{
	if(collision.gameObject.tag == "someTag")
	{
		Harvest(collision.transform);
	}
}

void Harvest(Transform obj)
{
	Destroy (obj.gameObject);
	Instantiate (objectToInstantiate, obj.transform.localPosition, Quaternion.identity);
}
