Application.CaptureScreenshot() Fails on PC/Mac

Do you get any errors in the log file? Are we talking about web or standalone build?

Standalone builds for either Mac OS or Windows.

I hadn't thought about the player logs, but I checked now and don't see any messages about it.

Could you try to build your app with "Development build" option enabled?

I tried this script and works fine (I'm using Mac):

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class Answer_1011955 : MonoBehaviour {
 
     static int numScreenshot = 1;
     public Text pathText = null;
 
     public void TakeScreenshot(){
         Application.CaptureScreenshot(Application.dataPath+"screenshot"+numScreenshot.ToString()+".png" , 4);
         pathText.text = "Screenshot saved into " + Application.dataPath+"screenshot"+numScreenshot.ToString()+".png";
         numScreenshot++;
     }
 }

Hi Jordi & Paulius,

After lots of testing I've realised that I was mistaken about what was happening in Windows (just got mixed up) and the problem is centred around Mac OSX.

For each platform I tried saving 3 ways: by appending Application.dataPath (i.e. Application.dataPath + "/" + "filename.png"), by appending Application.persistentDataPath, and with just the filename with no folder appended up front.

Here were my results...

Windows:

• dataPath: goes to the data folder under the .exe — not an ideal place for a screenshot, but okay

• persistentDataPath: goes into the persistent data folder as expected! (good)

• no folder: goes to the data folder under the .exe

Mac:

• dataPath: puts the screen inside the .app package, which is indeed where the data is, although this is not a location users should ever have to look for screenshots

• persistentDataPath: goes into a persistent data path, BUT this is a different persistent data path than the one used when running in Editor!

• no folder: file cannot be found anywhere! (no messages in log)

So, in short, there are two issues here, both of them Mac-specific:

1. The value of Application.persistentDataPath changes between Editor mode and a stand alone build.

This seems unintentional. In my case (company: Crafted Reveries Limited, app name: Shu's Garden) Editor mode resolves the path as "Library/Application Support/Crafted Reveries Limited/Shu_s Garden/". However, the stand alone build resolves it as "Library/Application Support/unity.Crafted Reveries Limited.Shu's Garden/".

That last bit seems like a bug in Unity.

1. When the full path isn't specified, the file doesn't go to a default location.

It seems to go nowhere.

Try using this;

Application.CaptureScreenshot(Path.Combine(Application.persistentDataPath, fileName));
