Hi friends!

How do you control time on the iPhone?
Is there any like SDL_GetTicks() to get miliseconds since app was launched?

I need something like that to control my animations and movements.
Any suggestion?

BTW: Better if I can use it through CPP.

Thanks a lot, I appreciate a lot your help and time.

The iPhone can control time? Finally I can go back and stop myself from dating that one girl.

Sorry... couldn't help it

I already saw that post. Perhaps nanoseconds is too much accurate, I only need miliseconds.

Did you use that method on a game? Do you think it is suitable for games? I mean, does that method add overhead? (I have no idea about this).

Thanks a lot for your help.

Accuracy being in nanoseconds vs. milliseconds has little to do with performance or overhead. We modify it so it returns time in seconds as a double precision float. Yes it works great for games, which is why we use it.

Yeah, the extra precision certainly isn't going to break anything, and it's not going to be slower really.

As Jake said, it returns the time as a double in seconds, so it's easy to work with.

Thanks a lot for replies.

As I just need miliseconds, What do you think (AnotherJake) if I modify your code with this?

miliseconds = (double)nanos*1.0e-6;
return miliseconds;

Thanks.

Yes, seems like that should do the trick. Need to reduce nanos by three orders of magnitude less than you would for seconds to get milliseconds. Accordingly, microseconds would be nanos * 1.0e-3
