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 ^.^ .
