why does this make unity stop working?

i want to make unity count for 2 seconds.
but couldnt make it done.

Code (JavaScript):

1. var timer : double;
2. var i : int;
3. function xxx()
4. {
5.    
6.     timer = Time.time +2.0;
7.     while(Timer.time<timer)
8.     {
9.       i=i+1;  
10.     }
11. }
12.  

 

That will loop infinitely, Time.time is always going to be less than Time.time + 2. You'll want to put a check in - probably an if, or use a Do() While() instead of just a while - to check when your timer is >= 2

 

Time.time returns the game time that has passed at the beginning of the frame. Within any kind of for, while or do loop it will remain constant. You need frames to pass before it changes.

Either do your looping in a coroutine with a yield return delay, or make use of the fact that Update is called once per frame.

Code (csharp):

1. float nextTime = 2f;
2. void Update()
3. {
4.   if (Time.time >= nextTime)
5.   {
6.     // do something
7.     nextTime = Time.time + 2f;
8.   }
9. }

 

my intention is to make a pause during the game for 2 seconds.
