Using "WaitForSeconds" as a timer

Hi, is there a way of using waitforseconds in a correct way? I am trying to use the following but it doesn’t work. I know how to use alternative methods but i am curious how waitforseconds could be used in such case.

function Update ()
{
LetsWait ();
}

function LetsWait ()
{
var i : int;
++i;
yield WaitForSeconds(2.0);
}

The script above doesn’t increment i variable regularly, instead it waits 2 sec and increment i variable continuously. What i want to do is incrementing i once per 2 sec. How to use waitforseconds in this purpose?
Thank you very much

I would recommend scrapping the WaitForSeconds and using InvokeRepeating.

so create a function for the incrementing the variable

InvokeRepeating("Increment", 0, 2);

function Increment () {

var i : int;
++i;

}

This will call the Increment function once every 2 seconds. If you want to wait a certain amount of seconds, change the 0 to desired number of seconds.

You can read more about InvokeRepeating here:

Be aware that Update calls your function EVERY FRAME. After 2 seconds have passed the value will start to increment each frame. What you want to do is to call the function in Start, and increment i in a while or for.

for(i=0;i<=9999999;i++)
    yield WaitForSeconds(2.0);

or something like that
