在我的項目中，我將相機(jī)圖像保存到一個文件夾中，但是每秒可節(jié)省約60。如何將保存的圖像數(shù)量減少到每秒10張左右？void Update(){ if (TLB) { DirectoryInfo p = new DirectoryInfo(path); FileInfo[] files = p.GetFiles(); saveFrame(path, "TLB", fileCounter); fileCounter = files.Length + 1; }} void saveFrame(string path, string type, int counter){ RenderTexture rt = new RenderTexture(frameWidth, frameHeight, 24); GetComponentInChildren<Camera>().targetTexture = rt; Texture2D frame = new Texture2D(frameWidth, frameHeight, TextureFormat.RGB24, false); GetComponentInChildren<Camera>().Render(); RenderTexture.active = rt; frame.ReadPixels(new Rect(0, 0, frameWidth, frameHeight), 0, 0); GetComponentInChildren<Camera>().targetTexture = null; RenderTexture.active = null; Destroy(rt); byte[] bytes = frame.EncodeToPNG(); string filename = path + type + "/" + "/" + frameName(type, counter); File.WriteAllBytes(filename, bytes);}

在Unity中一定時間間隔后重復(fù)執(zhí)行代碼
使用Update（）方法：
// Invoke the method after interval seconds
public float interval = 0.1f;
// time counter
float elapsed = 0f;
void Update()
{
elapsed += Time.deltaTime;
// if time is elapsed, reset the time counter and call the method.
if (elapsed >= interval)
{
elapsed = 0;
TakeShot();
}
}
void TakeShot()
{
// do your thing here...
}
使用InvokeRepeating（）方法：
// Invoke the method after interval seconds
public float interval = 0.1f;
float delaySeconds = 0f; // delay the first call by seconds
void Start()
{
InvokeRepeating("TakeShot", delaySeconds, interval);
}
void TakeShot()
{
// do your thing here...
}
注意：這兩種方法都是framerate和time-scale依賴的。
