Rainbow Folders - Custom folder icons in the project browser? Easy!

Hi @dock,

Unfortunately, Unity Collaborate and Unity Version Control overlays are not supported starting from Unity 2020.1+. There is simply no API to do that correctly. Also, Unity changed the way Editor handles those overlays significantly so using reflection calls isn't an option here as well.

We will keep monitoring this in case the situation will improve but there are no plans to add support for Plastic SCM or other VCS overlay in near future. Sorry for the inconvenience it may cause you...

 

@PhannGor No problem, I totally understand. Unity's editor UI is a mess and hopefully will settle down with 2021, when that becomes less unstable.

 

I'm getting this error on unity 2020.3.27f1:

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object

You're using an outdated version of the Rainbow Folders. Please get the latest version from Asset Store or through the package manager.

 

I came to ask a question, but I see you are in Ukraine. I hope you stay safe! You and your fellow people are in our thoughts and prayers on the other side of the world.

 

@PlasticGerm, thank you for warm words and overwhelming support from the whole civilized world! We really appreciate that!

Regarding your question related to our assets, please don't hesitate to ask. I'm not promising a fast answer due to obvious reasons but we're trying to provide support whenever we can.

Because this allows us to continue to spend our revenue on humanitarian aid for the Ukrainian people. Because we want to say "thank you" to all the people who sincerely support us during this difficult time. Because we want to make this world better, and that's what we could do best. We want to create, not destroy.

 

I saw there was an update, so I thought I would check in. My question was that I have had a number of times now where I import Rainbow Folders and I can no longer see anything other than the Favorites folder listed in the project window. When I go delete Rainbow Folders from the disk, the project window populates the folders just fine. Not sure what's going on?

 

@PlasticGerm, probably you're trying to import an outdated version of the Rainbow Folders. This asset heavily relies on UnityEditor API and that API is changing from version to version. To fix that issue with a broken project window, please remove your current installation of the Rainbow Folders from your project, update your Rainbow Folders asset in the Package Manager, and import the latest version into your project again.

Also, there could be an occasional issue with Unity itself. For some reason, Unity could try to import an outdated version of the asset in some circumstances. If previous steps didn't help then you could try to:

1. Find the Asset Store cache folder on your machine.
   For Windows it should be something like:
   User\AppData\Roaming\Unity\Asset Store-5.х\Borodar\Editor Extensions\System
   For Mac OS:
   User\Library\Unity\Asset Store-5.х\Borodar\Editor Extensions\System
2. Then delete all the packages in that folder
3. Open Unity Editor
4. Delete Plugins\RainbowAssets
5. Reimport the Rainbow Folders from the Asset Store again. At this point, Unity should download the correct version of the asset.

 

I'm using 2.3.1, which is showing as downloaded on 3/4/22. Using Unity 2020.3.24f1. When Rainbow Folders is installed, I have to go into explorer and delete the RainbowAssets folder since I can't do it in Unity - I literally can't see the folders. I redownloaded the package and deleted the assets folder and then reimported and that did work. However, this is not the first time I have seen this happen, and before I basically did the same thing - delete the RainbowAssets folder, and it started working on reimport. I'm almost wondering if perhaps it is in conflict with another asset. Just as an FYI when I saw it happen this time, these are the other assets I'm using on the latest project.

Hi is it possible to do partial, wildcard, or regex matches for folder names? For example, if I created a definition for "*Fonts", it would apply the style for folders that are named "Fonts", "My Fonts", "More Fonts", etc.

@GeorgeHuan
Seems like you're trying to import an older version of the Rainbow Folders. Please open the Package Manager, "re-download" the asset, and then re-import it into your project. Hope this helps!

 

Hi @jimmying,

Regarding regex rules, unfortunately, this is not supported yet. We have this feature planned for some of the next releases but it has performance limitations to be solved first.

 

Edit: PlasticSCM no longer conflicts with Rainbow Folders! Seems to work a lot better now as well!

 

Hello! Big fan, been using this asset for years. One thing I just noticed is that in Unity 2021.3.0 I'm not seeing the context menu option by right clicking a folder to change it's color and background.

Is it a known bug? I've imported a clean version of 2.3.1. If I add the folder path directly in the Ruleset object it does work, but it's not an ideal workflow.

Thanks in advance and keep up the good work!

 

Hi @Tayx,

To apply a custom icon and/or background for some folder in your project view, just hold the "modifier" key and click on any folder icon in the Unity project browser. By default, it’s the Alt key, but you can change it in Project Settings → Borodar → Rainbow Folders.

 

That's awesome thanks! Works great

 

Could you please describe which "same" situation you have?

 

Hi! First of all, great asset! This asset has became a required asset on all of my projects and working on something without this feels a bit weird for me.
So for my issue, I have tried to make a new project with the new LTS unity 2021 (2021.3.2f1). I tried to add this asset as always but it gave me some errors and prevent the project tab from loading.
I'll provide a screenshot of the errors below


Hopefully you can help me.

 

@Honoki_

Seems like you're trying to import an older version of the Rainbow Folders. Please open the Package Manager, "re-download" the asset, and then re-import it into your project. Hope this helps!

 

oooooh! It worked! Thank you!
Package manager didn't tell that there's any update so I thought I am using the latest version. But it worked again now. Thank you!

 

Is there a way to save the settings of Rainbow Packages on Git?

 

What does it mean that it's not supported? How does it look like when I have version control? Should I not buy it if I use Plastic?
Can somebody post a screenshot please?

 

The latest version of Plastic SCM has removed the icons that conflict with Rainbow Folders.

 

So does it mean it works? Should I buy?

 

Yep, Rainbow Folders now works with PlasticSCM, for me at least. That's up to you, of course, but I'll say that this is one of my favorite Editor assets!

 

Can I override the default folder icon somehow? I've been trying to use just a blank name in the ruleset but that doesn't work

 

No, there is no possibility to override the default folder. As a workaround, you can select all the root folders and apply the recursive rule to all of them.

 

Thank you!

 

[RF] There is no ruleset at path: Assets/Plugins/RainbowAssets/RainbowFolders/Editor/Data/RainbowFoldersRuleset.asset

This warning is strange, as Rainbow Folders doesn't use this folder. Any tips to avoid it?

 

Can't work with Unity 2021.3.8f1c1 ?

 

Yes, reading docs usually helps

Just go to Edit → Project Settings → Borodar → Rainbow Folders and update the folder location to your one:


Also, in the latest versions, this should be done automatically.

 

Should work fine. Please make sure you're using the latest version of the Rainbow Folders from the Asset Store.

 

Unity 2022.1.15f1:

 

Hi,
Could we using API from rainbow folder to get asset icon?
I would like to use custom icon setting to draw editor toolkit(pushpin) in my project.

 

I encountered the same error after upgrading my Unity from 2020.3.37 to 2020.3.38

 

@AdamLiu, @Figarist,

Just checked Unity 2022.1.15f1 and all works fine for me.

Usually, you need to update your assets after upgrading the Unity version. The same story for the Rainbow Folders as well. Please open the Package Manager, "update" or "re-download" the asset, and then re-import it into your project. This should help.

 

@makaolachsiungca,

Sure, you can. I do not fully understand your request but seems that you could use the Borodar.RainbowFolders.ProjectRuleset class for your needs. Something like:

Code (CSharp):

1.  
2. /// <summary>
3. /// Searches for a rule that has the same type and key values.
4. /// Returns the first occurrence within the settings if found; null otherwise.
5. /// </summary>
6. ProjectRuleset.Instance.GetRule(ProjectRule match)
7.  
8. /// <summary>
9. /// Searches for a folder config that should be applied for the specified path (regardless of
10. /// the key type). Returns the last occurrence within the settings, if found; null otherwise.
11. /// </summary>
12. ProjectRuleset.Instance.GetRuleByPath(string folderPath, bool allowRecursive = false)
13.  

Please don't hesitate to take a look at the source code. It's shipped together with package

@makaolachsiungca Hard to say... your code seems legit.

 

Hi, insanely useful asset, thanks!

I was wondering if you could add a check for source control. For example, we're using perforce, and when I change some folder's colors, it doesn't "check out" the ruleset file, so the colors won't be updated in our source control unless I manually check out the ruleset file.

This can usually be done doing this:
UnityEditor.VersionControl.Provider.Checkout("AssetPath/Asset.asset", CheckoutMode.Both);

Thanks in advance

 

Hi @marcrem,

There is the

Code (CSharp):

1. ProjectRuleset.OnRulesetChange

action you could use for your needs. Just subscribe to it from your editor script and call

Code (CSharp):

1. UnityEditor.VersionControl.Provider.Checkout("AssetPath/Asset.asset", CheckoutMode.Both);

or implement any other logic you want to execute after the ruleset is changed.

 

Hi there, I created some custom folder icons compatible with Rainbow Folders

https://github.com/gigacreation/UnityFolderIconExtras

 

I think Rainbow Folder might be broken in the Unity 2022.3.1f1. It looks like if there is an error the project window will fail to render folder and files properly. Will update if I can pinpoint the issue a little more thoroughly.

 

Hi @Meatloaf4,

Just double-checked it and seems to be working fine with the Unity 2022.3.2f:



Please make sure you're using the latest version of the Rainbow Folders 2 asset from the asset store (which is v2.4.0 at the moment).

 

Here we go,
The colorful icon must been evaluate manually via ProjectIconsStorage.GetIcons().
Now I have a custom pretty asset window!

Code (CSharp):

1. public static Texture2D TryGetIcon(DefaultAsset folder)
2.         {
3.             var rule = Borodar.RainbowFolders.ProjectRuleset.Instance.GetRuleByPath(folder.GetAssetPath(),true);
4.  
5.             Texture2D icon = null;
6.  
7.             if (rule != null)
8.             {
9.                 if (rule.HasIcon())
10.                 {
11.                     if (rule.HasLargeIcon())
12.                         icon = rule.LargeIcon;
13.                     else if (rule.HasSmallIcon())
14.                         icon = rule.SmallIcon;
15.                     else if (rule.HasCustomIcon())
16.                         icon = rule.LargeIcon;
17.                 }
18.                 else
19.                 {
20.                     Debug.LogError("None exist icon.");
21.                     icon = Borodar.RainbowFolders.ProjectIconsStorage.GetIcons(rule.IconType).Item2;
22.                 }
23.  
24.                 // load icon from color
25.                 if (icon == null)
26.                     return Borodar.RainbowFolders.ProjectIconsStorage.GetIcons(rule.IconType).Item1;
27.             }
28.  
29.             return EditorIcons.UnityFolderIcon;
30.         }

 

It is broken in Unity 2023.1.

 

Yes, just confirmed that. It seems like they changed the "Texture" API slightly. Working on a compatibility fix now.

 

Hello!
I get an error when I install Rainbow Folder, what should I do?

 

Hello @neumond,

Seems like you've installed a newer version of the RF2. It is just a warning that it didn't recognize the old ruleset using the old path from preferences. The next message means that it found a new one without any issues so you could continue to use the RF2 plugin.
