Unity：如何暂停执行，直到函数终止，以便跳过任何帧 [英] Unity: How to pause execution until function terminates, so as to skip no frames

问题描述

我正在写一个游戏/程序，每隔几秒钟必须向硬盘写入大量数据 - 这需要几秒钟的时间才能完成，并且自然会导致游戏在此期间挂起。

然而，当游戏在写完后恢复游戏时，游戏会跳过几帧。

我需要Unity 跳过绝对无框是如此。如何强制Unity引擎在写入完成前停止执行，以便在恢复时不会跳过任何帧？

---

为了提供一些上下文，我将捕获每帧的截图，并将它们作为Texture2D存储在队列中。当队列中有超过100帧的Texture2D时，我将它作为PNG写入磁盘，然后清除队列。

我想暂停渲染/执行，同时写入发生，以便输出（单独）无缝。

解决方案

您可以将timeScale设置为0，以便不调用Animation和FixedUpdate。

添加一些检查：

  void Update（）
 {
 if（Manager.cleaningTexture == true ）{return; } 
 //其余的代码
} 
  

I am writing a game/program which every few seconds has to write a lot of data to the hard disk - this takes a few seconds to complete, and naturally causes the game to hang for that duration.

However, when the game resumes after the writes have completed, the game skips a few frames.

I need it that Unity will skip absolutely no frames what so ever. How can I force the Unity Engine to stop executing until the writing has fully completed, so that when it resumes, no frames have been skipped?

---

To provide some context, I am capturing a screenshot every frame, storing them as Texture2Ds in a queue. When the queue has more than 100 frames worth of Texture2Ds in it, I am writing the to the disk as PNGs, and clearing the queue.

I want to pause rendering/execution whilst the writing takes place so that the output (alone) is seamless.

解决方案

You could set the timeScale to 0 so that Animation and FixedUpdate are not called.

As for the Update you would have to add some checks:

void Update()
{
    if(Manager.cleaningTexture == true){ return; }
    // Rest of the code
}
