Counting time

You could always create your own time manager that just adds one second to the time every 1000 milliseconds (you can get the milliseconds with GetTickCount()) and then adds one to minutes every 60 seconds, etc. This wouldnt be too hard to use if you put it all in a class.

Ok... So in the beginning of each player''s turn I have to get the current time and when there is +1000ms I add one second for the player?

Get the time at the beginning of their turn (with GetTickCount) and at the end of their turn get another GetTickCount. Then subtract the second one from the first and you will have how many milliseconds have passed during their turn.

Null and Void

But I''d like to update the time real-time not at end of turn.

That''s not a problem.
Some basic code:

int clock = 0; // the time elapsed DWORD time = GetTickCount(); // Loop starts here if (GetTickCount() - time >= 1000) // one sec passed clock++; // add one second to clock time = GetTickCount();

Now the hours will be: (int)(time / 3600)
The minutes will be: (int)(time / 60)
The seconds will be: time % 60

I have some (fairly ugly) code that I''m using for a high resolution timer in a game I''m writing. It''s a class with a lot of features you may not need, but I can send you a copy if you''d like.

What Tornado posted will work, but there is a small problem with it (which you may or may not care about). Inside that loop you are going to have to poll for input, draw graphics, etc, and those take time. Say your tickcount is at 999 (0.9 seconds) and after the next loop iteration it could be 1099 ticks (1.09 seconds). If you just lop off the remainder then you lose time. 0.09 seconds might not sound like much, but after a minute your clock would be off by over 5 seconds.

Anyways, it''s real easy to fix. When a second has passed subtract 1000ms (1 sec) from the time holder and add what is left to the next call to GetTickCount:

int clock = 0; // the time elapsed DWORD time = GetTickCount(); // Loop starts here if (GetTickCount() - time >= 1000) // one sec passed clock++; // add one second to clock // Don''t lose time time = (time - 1000) + GetTickCount();

Also, one more note. GetTickCount has a resolution of up to 55ms. In other words, the value returned by GetTickCount only changes every 55ms, so it is possible to "lose" 54ms every loop iteration, once again causing your clock to fall behind. If you want your timer to be accurate, then use QueryPerformanceCounter(), otherwise GetTickCount() works fine.

Well, I said the code was basic!
Houdini's right, If you want to get accurate as possible, use QueryPerformenceCounter().
Another thing, if I'm not mistaken, my code will overflow after ~ 9 hours and 6 minutes.
Just something to think about

Your best bet is to update your players'' timers by using WM_TIMER. Just start a timer, and increase the time of the players in the WM_TIMER event. It''s not the most accurate thing in the world but it works.
