Unity 截屏并保存成PNG

public class Test: MonoBehaviour
{
    void Update()
    {
        if (Input.GetMouseButtonDown(0)) {
                StartCoroutine(CaptureScreen(path));
        }
    }

    public IEnumerator CaptureScreen(string savePath)
    {
        yield return new WaitForEndOfFrame();

        var rect = new Rect(0, 0, Screen.width, Screen.height);
        Texture2D screenShot = new Texture2D((int)rect.width, (int)rect.height, TextureFormat.RGB24, false);

        screenShot.ReadPixels(rect, 0, 0);

        screenShot.Apply();

        byte[] bytes = screenShot.EncodeToPNG();

        var dirPath = "D:/Test/";
        if (false == System.IO.Directory.Exists(dirPath))
        {
            System.IO.Directory.CreateDirectory(dirPath);
        }

        string filename = dirPath + savePath + ".png";
        System.IO.File.WriteAllBytes(filename, bytes);
    }
}
