Calculating FPS
Author
I was wondering how i could calculate frames per second in a game i am making. I have a way to do it in VB, but i need one for C++. I was going to use the CTimer.GetSecond(), but to use that i have to include afx.h, and when i do that i get linking errors, so is there a different function i could use like VB''s Timer? Here is the one from a different game done in VB
''Calculate the frame rate
dim i as integer, fps as integer, tLast as integer
If i = 30 Then
If tLast <> 0 Then fps = 30 / (Timer - tLast)
tLast = Timer
i = 0
End If
i = i + 1
''(then write out variable fps)

If you are still interested in how to calculate it in C++, please mail me at mitolah@hotmail.com and I''ll tell you how to do it...
I will not say it here... it takes too much code!!

How about this (taken from D3Dframe of the DX7 SDK):
static DWORD dwLastTime = 0;
static float fFPS = 0;
static DWORD dwFrames = 0;
// Keep track of the time lapse and frame count
DWORD dwTime = timeGetTime();
dwFrames++;
// Update the frame rate once per second
DWORD dwTimeDiff = dwTime - dwLastTime;
if (dwTimeDiff > 1000) {
fFPS = (float)dwFrames / dwTimeDiff * 1000;
dwLastTime = dwTime;
dwFrames = 0;
}
// Print fFPS to show FPS
