How to copy the result of Sprite Editor from one atlas to another???

How to copy the result of Sprite Editor from one atlas to another similar atlas with the same names and Pivot coordinates? (see Figure)

 

You can't directly from Unity, but can trough a custom Editor script. Just made one as I need this kind of feature too:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4. using System.Collections.Generic;
5.  
6. //Copy and paste atlas settings to another atlas editor
7. public class AtlasCopyPasteEditor : EditorWindow
8. {
9.  
10.    public Texture2D copyFrom;           //Sprite Atlas to copy from settings
11.    public Texture2D pasteTo;           //Sprite atlas where to paste settings
12.  
13.    private Sprite[] _sprites;           //Collection of sprites from source texture for faster referencing
14.  
15.    [MenuItem ("Window/Atlas CopyPaste Editor")]
16.    static void Init()
17.    {  
18.      // Window Set-Up
19.      AtlasCopyPasteEditor window = EditorWindow.GetWindow(typeof(AtlasCopyPasteEditor), false, "Atlas Editor", true) as AtlasCopyPasteEditor;
20.      window.minSize = new Vector2(260, 170); window.maxSize = new Vector2(260, 170);
21.      window.Show();
22.    }
23.  
24.    //Show UI
25.    void OnGUI ()
26.    {
27.  
28.      copyFrom = (Texture2D)EditorGUILayout.ObjectField ("Copy From", copyFrom, typeof(Texture2D), true);
29.      pasteTo = (Texture2D)EditorGUILayout.ObjectField ("Paste To", pasteTo, typeof(Texture2D), true);
30.  
31.      EditorGUILayout.Space ();
32.  
33.      if(GUILayout.Button ("Copy Paste"))
34.      {
35.        if(copyFrom != null && pasteTo != null)
36.          CopyPaste ();
37.        else
38.          Debug.LogWarning("Forgot to set the textures?");
39.      }
40.  
41.      Repaint ();
42.    }
43.  
44.    //Do the copy paste
45.    private void CopyPaste ()
46.    {
47.      if(copyFrom.width != pasteTo.width || copyFrom.height != pasteTo.height)
48.      {
49.        //Better a warning if textures doesn't match than a crash or error
50.        Debug.LogWarning("Unable to proceed, textures size doesn't match.");
51.        return;
52.      }
53.  
54.      if(!IsAtlas (copyFrom))
55.      {
56.        Debug.LogWarning ("Unable to proceed, the source texture is not a sprite atlas.");
57.        return;
58.      }
59.  
60.      //Proceed to read all sprites from CopyFrom texture and reassign to a TextureImporter for the end result
61.      UnityEngine.Object[] _objects = AssetDatabase.LoadAllAssetRepresentationsAtPath (AssetDatabase.GetAssetPath (copyFrom));
62.      
63.      if(_objects != null && _objects.Length > 0)
64.        _sprites = new Sprite[_objects.Length];
65.  
66.      for (int i = 0; i < _objects.Length; i++)
67.        _sprites [i] = _objects [i] as Sprite;
68.  
69.      //Get Texture Importer of pasteTo texture for assigning sprite variables (pixxelsToUnit is not counted)
70.      string _path = AssetDatabase.GetAssetPath(pasteTo);
71.      TextureImporter _importer = AssetImporter.GetAtPath(_path) as TextureImporter;
72.    //   _importer.isReadable = true;
73.  
74.      //Force settings to Sprite and Multiple just to be sure
75.      _importer.textureType = TextureImporterType.Sprite;
76.      _importer.spriteImportMode = SpriteImportMode.Multiple;
77.  
78.      //Reassigning to new atlas
79.      List<SpriteMetaData> _data = new List<SpriteMetaData>();
80.  
81.      for(int i = 0; i < _objects.Length;  i++)
82.      {
83.        SpriteMetaData _meta = new SpriteMetaData();
84.        _meta.pivot = _sprites[i].pivot;
85.        _meta.name = _sprites[i].name;
86.        _meta.rect = _sprites[i].rect;
87.        _meta.border = _sprites[i].border;
88.        
89.        _data.Add(_meta);
90.      }
91.  
92.      //Add MetaData back to spriteshet from List to Array
93.      _importer.spritesheet = _data.ToArray();
94.  
95.      //Rebuild asset
96.      AssetDatabase.ImportAsset(_path, ImportAssetOptions.ForceUpdate);
97.    }
98.  
99.    //Check that the texture is an actual atlas and not a normal texture
100.    private bool IsAtlas (Texture2D tex)
101.    {
102.      string _path = AssetDatabase.GetAssetPath(tex);
103.      TextureImporter _importer = AssetImporter.GetAtPath(_path) as TextureImporter;
104.  
105.      return _importer.textureType == TextureImporterType.Sprite && _importer.spriteImportMode == SpriteImportMode.Multiple;
106.    }
107. }
108.  

Just put the script in the Editor folder and you should see the tool under Window/Atlas CopyPaste Editor on the top menu of Unity.

You will get some warning if something goes wrong, like unmatching texture sizes or the source texture not beign a Multiple sprites atlas. For the rest feel free to modify as you see fit.

 

Thank you very much Neurological!!! Necessarily use, and share experiences!!!
Cheers!!! =)

 

Neurological!!! You are best!!! Thanks dude!!! =)

 

You are welcome, glad it helped.

 

Really cool tool!!! Neurological bravo!!! =)
By the way I have earned after I put it also in the my unity Project > Assets > Scripts folder.

 

Still useful and working in 19/02/2017, thanks @Neurological !

 

TY @Neurological
One tip - destination texture have to be a Default Texture.

Hmm. Somehow pivots are not copy and stay centered.
Even if I turn pivots from pixels to relative 0..1

 

Here the fix for the pivot and all the other data.

 

Amazing stuff, this thread saves me so much time. Thank you, Thank you!

 

Really cool tool!!! Neurological bravo!!! =) vidmate app instasave.onl

 

There's another option for duplicating sprite editor settings for sprites which will have the exact same settings. It doesn't require any additional scripting, but it takes a little time for renaming maintenance.
1) Outside of unity (or in Unity), add only one of the sprites to your project.
2) In Unity, configure the sprite and its editor settings as you desire them all to be.
3) In Unity, duplicate that sprite and rename the duplicates as the names of all additional sprites desired (so its still just a duplicate but its name matches that of another sprite to be added).
4) Outside of unity, replace each of those duplicate sprites with the actual image for the name (so each duplicate in step 3 will be replaced the actual image).
5) Give Unity focus. Now, all your sprites have the exact same sprite editor settings!

This is the technique I use when adding a bunch and its handy.

 

Thanks!!!

 

attention!
never use #10 version
this will cause a very huge bug that the new sprite will have same internalID(in meta file) with old sprite and none spriteID(meta file too).
this will cause missing sprite.

#3 version editor is great without any problem.

 

I was using this and now I've got ruined references after migrating from 2020 to 2021 =((((
