How can I add in my Game Over prefab?

I have created a game over menu in my project, and saved it to a prefab, but I can not for the life of me figure out how to implement it into my CharacterDamage script. Below is a chunk of the script that controls death, and I have no idea how I should apply my prefab GameOverMenu to this. This is my first attempt at putting a game together, and I have been moving along smoothly until I got to this point. I’m sure its extremely simple, but I have searched the internet for a solution, and have failed to find one.

var hitPoints = 100.0;
var deadReplacement : Transform;
var dieSound : AudioClip;

function ApplyDamage (damage : float) {
	// We already have less than 0 hitpoints, maybe we got killed already?
	if (hitPoints <= 0.0)
		return;

	hitPoints -= damage;
	if (hitPoints <= 0.0)
	{
		Detonate();
	}
}

function Detonate () {
	// Destroy ourselves
	Destroy(gameObject);
	
	// Play a dying audio clip
	if (dieSound)
		AudioSource.PlayClipAtPoint(dieSound, transform.position);

	// Replace ourselves with the dead body
	if (deadReplacement) {
		var dead : Transform = Instantiate(deadReplacement, transform.position, transform.rotation);
		
		// Copy position & rotation from the old hierarchy into the dead replacement
		CopyTransformsRecurse(transform, dead);
	}
}

You can assign your GameOverMenu script to a gameobject prefab (which you already did, i think)

Then, assign that prefab to your player script from the inspector.
In JS, you can declare public variables (which will be assignable from the inspector) like:

var gameOverPrefab : GameObject;

After you assign the prefab to such a variable, you can simply Instantiate it when your player dies. (In your case, Detonate() function)

After the game object containing your menu script is instantiated, the script will work and (hopefully) show your menu.

Please let me know if you can’t get it to work, I’ll be glad to help if I can.
