Re: [Dev-C++] FPS counter?

Hi Stein!
Easy way to do this would be using GLUT.

#include <GL/glut.h>

and then use the glut timer function to determine when a second is over. =
  =20
int main(blabla) {
    blablabla
    glutTimerFunc(1000,time,1);
    blablabla
    glutMainLoop();
    return 0;
}
Well.  So far where we get the complete seconds from ...
Now the display callback function has to increment the framecounter =
every time its called.  And our fps-calculator looks like this:
static int frames,oldframes,fps;
void time(int egal) {
    glutTimerFunc(1000,time,1);
    fps =3D frames - oldframes;
    oldframes =3D frames;
}
By now you have a variable that gets updated every second displaying how =
many fps your're displaying at.

If you wanted to do something really bound to time, like e.g. want to =
determine, if you'll have to leave out some frames or use them twice =
(for constant framerate), you should use something else than glut.  I =
haven't tried, yet.  If you figured out a better method it would be =
greatly aprecciated if you shared it with us.
