Destroyed clones freezing but not disappearing?

Hi All,
I’m trying to destroy a projectile after a specific period of time, to increase perfomance (on mobile). The projectile is instantiated from a prefab and the script is on a dummy object usd as an emitter. I have a number of collisions working fine and the instantiation.

The problem I’m having is that the cloned object freezes, but does not disappear from display. What do I need to do to make the cloned object destroy and remove itself from the scene?

This is the script (JS) attached:

var projectile : Rigidbody;
var projectileSpeed :int = 100;

function Update(){ 
if (FireButton.fired==true){
	var projectileClone : Rigidbody;
	projectileClone = Instantiate(projectile, transform.position, transform.rotation);
	projectileClone.velocity = transform.TransformDirection (Vector3.forward * projectileSpeed);
	Destroy(projectileClone,1);//this is supposed to destroy the clone after 1 second	

Any advice would be appreciated.

Best Regards

You’re only destroying the rigidbody. You need to destroy the GameObject. Make your projectileClone of type GameObject instead, or Destroy(projectileClone.gameObject).
