A Timer Function.

DWORD m_FPSTimer;
DWORD m_FPS;
FILE* Stream;
stream = fopen("fps.txt", "a");
Draw()
{
m_FPS = ( 1000/( timeGetTime() - m_FPSTimer() ) );
m_FPSTimer = timeGetTime();
fprintf(stream,"%d",m_FPS);
}

I hereby give you my fps-class:

class Fps {
int framecount;
DWORD framestarttime;
int fps;
char buffer[50];
public:
Fps(void) : framecount(0) {}
void Start(void) { framestarttime=GetTickCount(); }
void Stop(void) {
fps=(int)(GetTickCount()-framestarttime);
fps=1000/(fps+1); //+1=security flag to make answer >=1, to avoid probable division by zero!
}
void Draw(void) {
sprintf(buffer,"Frames Per Second=%d",fps);
Draw_Text_GDI(buffer,0,SCREEN_HEIGHT-20,RGB(120,220,20),lpddsback);
}
};


Use it like this in your main-loop or whatever:
Fps framespersecond;
while(1)
{
framespersecond.Start();

Game_Main();

framespersecond.Stop();
}

In Game_Main() you can plot the fps like this:
framespersecond.Draw();


Note: I don''t assure you that this class is correct at all, it might be totally wrong.
If someone knows that this is wrong, please tell me.

Why bother with a class for FPS? It''s not like you''re going to create an large amount of Fps objects now is it?

m_grinder: Where in Värmland are you at? Karlstad by any chance?

If you use winapi you can call GetTickCount. It is either in the kernel or user32. Try the following when using it.

StartTime = TickCount
Do_What_Ever
EndTime = TickCount
Time_It_Took = EndTime - StartTime

Check the DX samples. They have framerate code.

Sorry I can''t help you with finding the call. My computer just got a virus and I lost everything.
