attack script, dont know where to start...

how would a script go that has the object attack once every 1 and a half seconds? I dont need damage applied, but I am wondering how I could accomplish that or if possible, if someone could write it for me.

try this:

var canAttack = false;

function Update () {
	if (canAttack) {
		canAttack = false;
		SendMessage("Attack");
	}
	
	if (!canAttack) {
		SendMessage("Reset");
	}
}

function Attack () {
	// attack script stuff here
}

function Reset () {
	yield WaitForSeconds(1.5);
	
	canAttack = true;
}
