游戏开发：如何限制FPS？ [英] Game Development: How to limit FPS?

问题描述

我在写一个游戏，我看到FPS算法不能正常工作（当他必须计算更多，他睡得更长...）所以，问题很简单：如何计算睡眠时间具有正确的FPS？

I'm writing a game, and I saw the FPS algorithm doesn't work correctly (when he have to calculate more, he sleeps longer...) So, the question is very simple: how to calculate the sleeptime for having correct FPS?

我知道更新游戏需要多长时间，以微秒为单位，当然是我想达到的FPS。

I know how long it took to update the game one frame in microseconds and of course the FPS I want to reach.

我搜索疯狂的一个简单的例子，但我找不到一个....

I'm searching crazy for a simple example, but I can't find one....

代码可能是Java ，C ++或伪....

The code may be in Java, C++ or pseudo....

推荐答案

每帧的微秒数为 1000000 / frames_per_second 。如果您知道您已经花费 elapsed_microseconds 计算，那么您需要睡眠的时间为：

The number of microseconds per frame is 1000000 / frames_per_second. If you know that you've spent elapsed_microseconds calculating, then the time that you need to sleep is:

(1000000 / frames_per_second) - elapsed_microseconds
