Problem Min and Max Time

I wrote a little guide on timers for someone else, so here it is for you to read, absorb and learn from :

in response to another question : Ive looked at a few different ways of making a timer but there not making any sense to me, could you help me out?

I personally have seen 2 types of timer/counter. The first is with a 'timer' and a maximum value.

 var timer : float = 0.0;
 var timerMax : float = 5.0;
 
 function Update()
 {
     if ( timer > timerMax )
     {
        // do stuff
        // reset timer 
        timer = 0.0;
     }
     // increment timer over time
     timer += Time.deltaTime;
     
     // increment timer with an integer value (like counting frames)
     // timer ++; // like this, timer can be an integer (counter)
 }

the other method is using Time.time itself, but it still need an increment value to work.

 var timer : float = 0.0;
 var timerDelay : float = 5.0;
 
 function Update()
 {
     if ( Time.time > timer )
     {
        // do stuff
        // reset timer
        timer = Time.time + timerDelay;
     }
 }
