Devlog #8 - Screenshot Tool for Unity

Implementation

Here’s a simple script you can add to your Unity projects to take screenshots.

1. Create a C# file Assets/Editor/CaptureScreenshotWindow.cs and paste the following code:

   c#

   public class CaptureScreenshotWindow : EditorWindow
       {
           private static string lastScreenshot = "No screenshot taken yet...";
   
           private void OnGUI()
           {
               GUILayout.Label("Screenshot Tool", EditorStyles.boldLabel);
   
               if (GUILayout.Button("Capture Screenshot"))
               {
                   CaptureScreenshot();
               }
   
               GUILayout.Space(10);
               GUILayout.Label("Last Screenshot:", EditorStyles.label);
               GUILayout.TextField(lastScreenshot);
           }
   
           [MenuItem("Tools/Screenshot/Open Screenshot Window")]
           public static void ShowWindow()
           {
               CaptureScreenshotWindow window = GetWindow<CaptureScreenshotWindow>("Screenshot Tool");
               window.minSize = new Vector2(300, 100);
           }
   
           [MenuItem("Tools/Screenshot/Capture Screenshot Now")]
           public static void CaptureScreenshot()
           {
               // Generate Filename
               int randomIdx = RandomUtils.GenerateRandomNumber();
               string timestamp = DateTimeUtils.GetCurrentTimestamp();
   
               // Create folder path
               string folderPath = Path.Combine(Application.dataPath, "../Screenshots");
               Directory.CreateDirectory(folderPath); // Ensure the folder exists
   
               string filenameOnly = $"screenshot_{timestamp}_{randomIdx}.png";
               string fullPath = Path.Combine(folderPath, filenameOnly);
   
               // Capture Screenshot (relative to project root)
               ScreenCapture.CaptureScreenshot(Path.Combine("Screenshots", filenameOnly));
   
               // Show a popup in the Unity Editor
               EditorUtility.DisplayDialog("Screenshot Captured", $"Screenshot saved as:\n{fullPath}", "OK");
               lastScreenshot = fullPath;
           }
       }

2. In the top menu, go to Tools → Screenshot → Open Screenshot Window.

3. Take a screenshot! You’ll find it in the Screenshots folder at your project root.

That’s all! Hope it is helpful!

Tip: Adjust your game view resolution before capturing the screenshot.
