[Solved]Draw FPS each second

[Contadotempo]

Hi,
I'm trying to make a function that would draw how many FPS were displayed each second.
The original function is:

Code: [Select]

double app_properties::draw_fps()
{
stringstream ss;
getfps=1/(App.GetFrameTime()); //getfps is a float declared in the app_properties class
ss << getfps;
dfps.SetText("FPS: " + (ss.str()).substr(0,2)); //dfps is a font string declared in the app_properties class
App.Draw(dfps);
return getfps;
}

How could I change this and make it draw the FPS only each second?
This is probably very easy to do, but I'm being dumb...

Thanks in advance!

You have to add two parameters. A counter and clock.
When the clock equal 1s, else draw counter and reset clock and counter.

And you also could use static variable. like that

Code: [Select]

int app_properties::draw_fps()
{
static bool init = false;
static sf::Clock clock;

if(init == false)
{
init = true;
clock.reste();
}

getfps=1/(App.GetFrameTime()); //getfps is a float declared in the app_properties class

if(clock.GetEllapsedTime() >= 1.0)
{
clock.reste();
stringstream ss;
ss << getfps;
dfps.SetText("FPS: " + (ss.str()).substr(0,2)); //dfps is a font string declared in the app_properties class
App.Draw(dfps);
}

   return getfps;
}

Aah, that was quite simple after all.
Thank you both   :wink:
