How to limit FPS in a loop with C++?

Question

I\'m trying to limit the frames per second in a loop that is performing intersection checking, using C++ with chrono and thread.

Here is my code:

std::ch         


        

Answer 1

I usualy do something like this:

#include 
#include 

int main()
{
    using clock = std::chrono::steady_clock;

    auto next_frame = clock::now();

    while(true)
    {
        next_frame += std::chrono::milliseconds(1000 / 5); // 5Hz

        // do stuff
        std::cout << std::time(0) << '\n'; // 5 for each second

        // wait for end of frame
        std::this_thread::sleep_until(next_frame);
    }
}

Output: (five for each second value)
