Resolved Screenshot didn't appear in the folder

I am trying to make an album with Unity. First, I want to save screenshots. My script is as follows. However, when I press the key "S" to take screenshot for the first time, it didn't appear in the folder except that I switch the window to wait for compiling. If I continue to press key, the subsequent screenshots will show correctly. I can't figure out why. Is there anyone can help me? Thank you!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using System.IO;
5. using UnityEditor;
6. using System;
7.  
8. public class TakeScreenshot : MonoBehaviour
9. {
10.      private int screenshotCount = 0;
11.      private string screenshotFileName;
12.      private string folderPath;
13.      void Start()
14.      {
15.          folderPath = Application.dataPath + "/Resources/Textures/";
16.          if (!System.IO.Directory.Exists(folderPath))
17.             System.IO.Directory.CreateDirectory(folderPath);
18.      }
19.    
20.      void Update()
21.      {                    
22.         if (Input.GetKeyDown(KeyCode.S))
23.          {
24.              StartCoroutine(CaptureScreenshot());          
25.          }
26.      }
27.  
28.      private IEnumerator CaptureScreenshot()
29.      {
30.           screenshotCount ++;
31.           screenshotFileName = "Screenshot_" + screenshotCount + ".png";
32.           ScreenCapture.CaptureScreenshot(folderPath + screenshotFileName);
33.           AssetDatabase.Refresh();
34.           yield return new WaitForEndOfFrame();
35.      }
36.    
37. }

 

This script uses

UnityEditor

so keep in mind it will not build to your final game. You would need to guard out the UnityEditor code with #if UNITY_EDITOR checks.

Line 33 appears to be the correct refresh call. Have you tried inserting a

yield return null;

statement just before it?

 

It works! Thanks a lot!
