   can you not just make a cocos schduler that adds 1 to an int every second, then display the int in the label?

   Hi, you can do the following:

   In your layer i suppose,

   [self schedule:@selector(countUp) interval:1];

   and then:

   -(void)countUp
   {
   count++;
   }

   And then in your countUp method add the following:

   [countLabel setString:[NSString stringWithFormat:@"%i", count]];

   This assumes you've declared countLabel and set it's parameters, location, etc.

   Hi, I'm not on my mac so I'm not 100% sure this is correct code but it would be better to do this

   ...
   [self schedule:@selector(countUp:) interval:1];
   ...
   
   -(void)countUp:(ccTime)dt {
   count+=dt;
   }

   This will make the counting up accurate, the value dt you get is the time between the actual intervals. Even though you put interval:1 there its not actually 1 second between each interval, its more like 0.99123, although this seems insignificant it does add up, slightly I admit but it still does. So why not do it like this, its not like its any harder ^.^ .

   it gives an error, because count is not declared.

   count has to be declared like this

   int count

   Sorry but this topic reminds me a lot of, -this- topic http://www.cocos2d-iphone.org/forum/topic/3657#post-22149 with the same results.

   did you set 'self->count = 0'; in the initializer?
