Making fireballs shoot every few number of seconds

Unity Engine

I want to be able to shoot my fireballs every few seconds so that it will match my animation that shoots it. So the script will only work every few seconds or as long as it takes for the animation to finish. How would I go about doing this?

heres my script

var bullitPrefab:Transform;

function Update () 
{
	if(Input.GetButtonDown("Fire2"))
	{
		var bullit = Instantiate(bullitPrefab, GameObject.Find("fireball").transform.position, Quaternion.identity);
		bullit.rigidbody.AddForce(transform.forward * 1000);
	
	}
	
}

Hello there!

By adding a float which will act as a timer you can easily build in a cooldown.

var bullitPrefab:Transform;
var cooldown:float = 0.0;

function Update () 
{
        if(cooldown > 0)
                cooldown -= Time.deltaTime;
	else if(Input.GetButtonDown("Fire2"))
	{
		var bullit = Instantiate(bullitPrefab, GameObject.Find("fireball").transform.position, Quaternion.identity);
		bullit.rigidbody.AddForce(transform.forward * 1000);
	        cooldown = 0.5;
	}
	
}
