turning a flame on and off

Unity Engine
1

The fire is turning on and off properly when I press “E”, my only problem is the yield WaitForSeconds part. I want the fire to stay on until I turn it off and stay off until I turn it on. Right now it only stays on for 5 seconds, but if i remove the yield WaitForSeconds(5) part, the fire won’t turn on at all. Here is my javascript.

*edit: I can always change the WaitForSeconds to like 10,000 seconds, but I’m sure there is a more practical way

#pragma strict

var theFire : Transform;
var flame : GameObject;
private var drawGUI = false;
private var fireIsOff = true;

function Start () {

}

function Update () {
	if (drawGUI == true  Input.GetKeyDown(KeyCode.E))
	{
		changeFireState();
	}
}

function OnTriggerEnter (theCollider : Collider) {
	if (theCollider.tag == "Player")
	{
		drawGUI = true;
	}
}

function OnTriggerExit (theCollider : Collider) {
	if (theCollider.tag == "Player")
	{
		drawGUI = false;
	}
}

function OnGUI () {
	if (drawGUI == true)
	{
		GUI.Box(Rect(Screen.width*0.5-51, 200, 102, 22), "Press E to use");
	}
}

function changeFireState () {
	if (fireIsOff == true)
	{
		//theFire.animation.CrossFade("On");
		//flame.emit = true;
		//particleSystem.enabled = true;
		flame.active = true;
		fireIsOff = false;
		yield WaitForSeconds(5);
	}
	if (fireIsOff == false)
	{
		//theFire.animation.CrossFade("Off");
		//flame.emit = false;
		//particleSystem.enabled = false;
		fireIsOff = true;
		flame.active = false;
		yield WaitForSeconds(3);
	}
}

just take both yield waitforsecs away, and use if / else statement …not two ifs in change firestate:

if (fireIsOff)
doStuff…
else
doOtherStuff

Thanks for your help. Don’t know why I didn’t think of that.
