用来限制 fps
#pragma once #include <windows.h> struct fps_limit { int previous_time; int tpf_limit; int tpf; fps_limit(int fps = 60) : previous_time(GetTickCount()), tpf(0) { limit_fps(fps); } void reset() { previous_time = GetTickCount(), tpf = 0; tpf_limit = 60; } void limit_fps(int fps) { tpf_limit = (int)(1000.0f / (float)fps); } void delay() { tpf = GetTickCount() - previous_time; if(tpf < tpf_limit) Sleep(tpf_limit - tpf - 1); previous_time = GetTickCount(); } };
test:
#include <iostream> using namespace std; #include "fps_limit.h" int main() { fps_limit fps(60); int i = 0; while(1) { cout << i++ << " "; fps.do_limit(); } }
