I'm trying to use chrono library for timers and durations.
I want to be able to have a Duration frameStart;
( from app start )
and a Duration frameDelta;
( time between frames )
I need to be able to get the frameDelta
duration as milliseconds and float seconds.
How do you do this with the new c++11 <chrono>
libraries? I've been working on it and googling ( information is sparse ). The code is heavily templated and requires special casts and things, I can't figure out how to use this library correctly.
Is this what you're looking for?
#include <chrono>
#include <iostream>
int main()
{
typedef std::chrono::high_resolution_clock Time;
typedef std::chrono::milliseconds ms;
typedef std::chrono::duration<float> fsec;
auto t0 = Time::now();
auto t1 = Time::now();
fsec fs = t1 - t0;
ms d = std::chrono::duration_cast<ms>(fs);
std::cout << fs.count() << "s\n";
std::cout << d.count() << "ms\n";
}
which for me prints out:
6.5e-08s
0ms
