Resolved The type or namespace name 'Localization' does not exist in the namespace 'UnityEngine'

I successfully made the package work for changing texts in the Editor for GameObjects.

Now I wanted to change text that I have in scripts, and when putting

Using UnityEngine.Localization;

at the top, I'm getting the error

The type or namespace name 'Localization' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

Am I missing a step somewhere?

Thanks!

 

I don't even know what that is... so I'm assuming no? Where would I check that?

 

Ha!! Looks like I was! Thank you for that!

 

@karl_jones I'm running into this same issue but I don't have an asmdef file. I'm on Unity 2020.3.15f1, Localization package 1.0.0-pre.10.

I can create the localization components on the UI and add them to my TextMeshPro gameobjects
Created the strings table and referenced the string I want
Created a Global variables group with a global variable that's picked up by the component and updates appropriately

But I can't access the global variables group through code since it complains that Localization isn't a namespace within Unity Engine. Is there another place that I need to be referencing the package? This is the first time I've run into this kind of issue even with using the Analytics package and other non-standard ones.

 

@karl_jones Thanks for the fast response.

Full error message:
The type or namespace name 'Localization' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?) [Assembly-CSharp]csharp(CS0234)

Code is just trying to access LocalizationSettings object:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Analytics;
5. using UnityEngine.UI;
6. using UnityEngine.Localization;
7. public static class GameData {
8.     public class Settings {
9.         private bool soundEnabled = true;
10.         private bool musicEnabled = true;
11.         private bool notificationEnabled = true;
12.  
13.         public Settings() {
14.             var source = LocalizationSettings
15.                 .StringDatabase
16.                 .SmartFormatter
17.                 .GetSourceExtension<GlobalVariablesSource>();
18.         }
19.     }
20. }

 

To test, I tried loading a sample from the package manager into the project. The moment I did so the errors resolved themselves. Seems a bit strange the package was installed but somehow my own scripts couldn't reference the namespace but when a sample was loaded it could.

Is there some hidden build file or similar inside of Unity for how it resolves imports? The package manager showed it installed...

Either way, if anyone else runs into this try just importing a sample into the project to see if that resolves the reference issue.

 

Yes same solution for me. Adding a sample fixed it.

 

What sample is it? How do I add it?
I am stuck with the same problem.

 

Hello, I'm running into the same issue. I can't access the UnityEngine.Localization namespace after installing the Localization package and I don't know how to reference the localization asmdef. Currently I had not run into this issue with other namespaces form other installed packages. The Unity.Localization.dll is in the project Library > ScriptAssemlies. How should I fix this?

Thanks in advance

 

Hello Karl! And thanks for reaching out. On the day I installed the Localization package I was trying to use the UnityEngine.Localization namespace but it could not be found, even though everything was installed correctly. I even tried to close and reopen my Unity project but that did not work either. Today after restarting my computer the issue was gone and now I can normally use the Localization namespace. Maybe turning the computer off and then back on may fix the issue for other people.

Thanks again for reaching out.

 

I just observed an error similar to this in Daggerfall Unity. The included code was:

Code (CSharp):

1. using System;
2. using System.Collections.Generic;
3. //using UnityEditor;
4. //using UnityEditor.Localization;
5. using UnityEngine.Localization.Settings;
6. using UnityEngine.Localization.Tables;

With error message "cs0234 namespace localization does not exist in UnityEditor"

I added a sample and that did resolve the issue. At which point I started removing and manipulating until I reached this statement "namespace UnityEditor.Localization{}". Simply adding that allowed the build to continue.

Code (CSharp):

1. using System;
2. using System.Collections.Generic;
3. using UnityEditor;
4. using UnityEditor.Localization;
5. using UnityEngine.Localization.Settings;
6. using UnityEngine.Localization.Tables;
7. namespace UnityEditor.Localization{}

Following that principle, this statement would probably resolve the poster's issue "namespace UnityEngine.Localization{}"
"Resolve" is a pretty hard term, work around, or fake would be more appropriate.

 

I had a question for you Karl. The only analogue I can think of is that "using UnityEditor.Localization;" would be similar to "#include <string>" in that it's some kind of include. Unlike a C++, however, it seems that a code reference is required. I could use "#include <string>" without ever calling a function like "std::string" and that wouldn't generate an error.

In this case it seems as if using the include "using UnityEditor.Localization;" requires a function of the namespace to exist somewhere within code so that a corresponding "namespace UnityEditor.Localization{}" is required. In the examples, this wouldn't be the case. It seems like we just need the root when a function is built, something like "namespace UnityEditor.Localization.Work{}" where "Work" references "UnityEditory.Location" and thus becomes a sub-function.

Just keep in mind that I am not a coder and don't really know how any of it works. I'm pretty good at sleuthing out bugs that prevent a program from compiling, but that's just the application of other people's solutions.

Edit:
I was seeing "namespace UnityEditor.Localization.Samples" and thought that meant "Samples" was user defined but I can see in the documents that that is, in-fact, a global namespace. It looks like code should normally be grouped within one of these defined namespaces? That should prevent the error. ASMDEFs aren't used in Daggerfall Unity, so maybe having an ASMDEF would change the behaviour slightly?

My guess is that placing the code within a global namespace is what triggers the include to be "linked" or "loaded". Pure speculation, though.

 

Hey all,

I have the exact same issue. I'm using 2020.3.5.f1.
Please, what are the exact steps I have to do so that Unity recognize this namespace ?
(I have no asmef specifically defined, plain creation from the Unity Hub)

Thanks, regards.

 

Code (csharp):

1. using UnityEngine.Localization;

-> I have it at the top, that is the reason why Unity/Class loading is complaining about this dependency.

Do you have the localization package installed?
-> I don't know where to check... since in the package Manager there are no traces of a package containing the "Localization/Locale" string (checked in Unity Registry only). I'd imagine it's bundled naturally whenever I created a URP 2D project ? Perhaps should I install it from a specific URL ?

Where is your script that is causing the issue?
-> My script is under Assets/scripts/...

Thanks for the anwser

 

Thanks, I could install it... I had to downgrade my existing newtonsoft library to match the dependency of the package. (hope no regressions will be there...)

However, now I have the following in the console, I presume due to the adressable dependency.

Code (csharp):

1. Library\PackageCache\com.unity.addressables@1.20.5\Runtime\AssetReference.cs(924,27): error CS0117: 'AssetDatabase' does not contain a definition for 'SaveAssetIfDirty'

 

My Mistake I was on 2020.3.5.f1 NO 2021.3.5.f1.

 

Taking the latest (Unity 2020.3.43) worked our for me. Thanks Karl !
Now I've got things compiling, and the project run (no regression on the upgrade from 3.15 luckily observed).

So now If I want to take the language from steam, do I still need to use the SteamWork APIs (c#) or should I use somehow a wrapper from this newly installed lib ? (I understand this lib is mainly for organizing localized specific assets, but I've got rooted to install it from another thread suggesting to do so when willing to get steam default language)

 

yep was working on my way for that...

Code (csharp):

1.  
2. [DisplayName("Steam Selector")]
3.     [Serializable]
4.     public class SteamStartupSelector : IStartupLocaleSelector {
5.         public Locale GetStartupLocale(ILocalesProvider availableLocales) {
6.             var lSteamLoc = SteamManager.instance.steamLocale;
7.             Debug.Log(string.Format("steam locale:{0}", lSteamLoc));
8.             return availableLocales.GetLocale(lSteamLoc);
9.         }
10.     }
11.  

Thanks Karl, I guess the rest I'll have to test from the build itself since the steam API do not work in the Editor...
Bye.

 

By any chance do you know when the method "public Locale GetStartupLocale(ILocalesProvider pAvailableLocales)" is being called ? Do I have possibility to include it in the script order execution ?

 

Hey all,
Errors appear when building a project:

Code (CSharp):

1. Assets\Localizations\Local\DataTest.cs(1,19): error CS0234: The type or namespace name 'Localization' does not exist in the namespace 'UnityEditor' (are you missing an assembly reference?)

Code (CSharp):

1. Assets\Localizations\Local\DataTest.cs(8,30): error CS0246: The type or namespace name 'StringTableCollection' could not be found (are you missing a using directive or an assembly reference?)

How can this problem be solved?

The script is located in the Assets folder, I have no asmef specifically defined, tested on Unity 2021.3.11, 2021.3.19, 2022.2.2.
Here is an example of the code where the error occurs:

Code (CSharp):

1. using UnityEditor.Localization;
2. using UnityEngine;
3. using UnityEngine.Localization.Components;
4. using UnityEngine.Localization;
5.  
6. public class DataTest : MonoBehaviour
7. {
8.     [SerializeField] private StringTableCollection table;
9.     [SerializeField] private LocalizeStringEvent local;
10.  
11.     private string key = "first";
12.     void Start()
13.     {
14.         SetString(key);
15.     }
16.  
17.     public void SetString(string key)
18.     {
19.         local.SetTable(table.name);
20.  
21.         local.SetEntry(key);
22.     }
23. }

 

Yes indeed, you are right.
I would like to get a list with all the keys in a certain table.
The StringTableCollection has a GetrowsEnumerator() method for working with keys in a table, but is there something similar for a LocalizedStringTable?

 

Oh, thanks, it worked.
