我收到异常 DirectoryNotFoundException，当按一次 k 键时，它会不停地截取屏幕截图，我希望每次按 k 键时它都截取一张屏幕截图。
我收到异常 DirectoryNotFoundException
您可以使用Path.GetDirectoryName来获取完整的目录路径，但不包含filename.
然后你可以简单地使用 Directory.CreateDirectory
在指定路径中创建所有目录和子目录，除非它们已经存在。
So.you 甚至不必检查它是否存在。（当然，您仍然需要获得许可才能这样做）
按一次 k 键时，它会不停地截取屏幕截图，我希望每次按 k 键时它都截取一张屏幕截图。
这是一个后续错误。由于您遇到异常，您永远不会到达该行
takeHiResShot = false;
一般来说，不如在这里使用协程，例如
public void TakeHiResShot()
{
StartCoroutine (ScreenshotRoutine ());
}
void Update()
{
if(Input.GetKeyDown("k"))
{
StartCoroutine (ScreenshotRoutine ());
}
}
private IEnumerator ScreenshotRoutine ()
{
yield return new WaitForEndOfFrame();
var rt = new RenderTexture(resWidth, resHeight, 24);
camera.targetTexture = rt;
var screenShot = new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false);
camera.Render();
RenderTexture.active = rt;
screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
camera.targetTexture = null;
RenderTexture.active = null; // JC: added to avoid errors
Destroy(rt);
var bytes = screenShot.EncodeToPNG();
var filename = ScreenShotName(resWidth, resHeight);
var directory = Path.GetDirectoryName(filename);
Directory.CreateDirectory(directory);
System.IO.File.WriteAllBytes(filename, bytes);
Debug.Log($"Took screenshot to: /"{filename}/"", this);
}
这使得在出现错误的情况下不可能陷入无限循环
