Quick Start Guide

This guide will take you through setting up a simple Project with localized Assets and strings.

1. Create the Localization Settings

The Project's Localization Settings is an Asset. To create this Asset, go to Edit > Project Settings > Localization and click Create

2. Create Locales

Locales represent regions; they determine which language you are localizing your application to, and other localization decisions.

To open the Locale Generator window, navigate to the Localization Settings (menu: Edit > Project Settings > Localization) and click the Locale Generator button.

To select a Locale, tick the toggle box next to its name. Tick the checkbox next to the Locale you want to add, then click the Create Locales button and select where you want to save the Assets to.

3. Choose a default Locale

Use the Locale Selectors to determine which Locale your application uses by default if it is not English(en). To do this, add the Locale to the Specific Locale Selector field. Your application uses this Locale on start-up, and when no other Locale is selected.

4. Texture Localization: Create an Asset Table Collection

There are many reasons you might need to localize an Asset. For example, you might want to play a different piece of voiceover audio or music, or change a texture that contains written text (such as a signpost). The localization system uses Asset Tables to support this.

This demonstrates changing an Asset's Texture to the flag of that Locale's country.

First, you need to create an Asset Table. To do this, open the Localization Tables Window (menu: Window > Asset Management > Localization Tables).

In the Asset Tables window, select the New Table Collection tab. Select which Locales you want to generate tables for, give the collection a name and click the Create Asset Table Collection e button and choose a directory to generate the assets.

Click Edit Table Collection and select the My Assets table.

A table contains a Key field and a value field for each Locale. Unity uses the Key to identify the localized Asset. For this tutorial, name the Key Country Flag and use + button to add the key entry.

Select the Texture you want Unity to display for each Locale, and then drag and drop it into the corresponding section of the table, like so:

5. Texture Localization: Use the localized Asset

There are multiple ways for Unity to access a localized Asset. This tutorial uses components provided by the localization system, so you do not need to write any scripts.

Add a UI Raw Image component to the Scene, you will need the Unity UI package installed in the project to use a Raw Image. Add the Raw Image, go to GameObject > UI > Raw Image. To localize a Raw Image component, right-click the component and then click Localize.

This adds a new component called Localize Texture. This is a generic localization component. When you add it via the Localize option, Unity automatically configures it to localize that component.

Use the Localized Asset Reference field to select the Country Flag Key you added to the Texture Asset Table previously.

Run the Scene and use the Game View Locale selection dropdown to change the Locale. If everything is configured correctly, the country flag changes to the assigned Texture in the Asset Table. If the Game View menu does not appear it can be enabled from the Localization Project Settings.

6. Audio Localization: Use the localized Asset

To localize Audio Clips, we could follow the same process as localizing the Texture however it is also possible to create and edit the localized assets in the inspector as follows:

1. Add a Audio Source GameObject (menu: GameObject > Audio > Audio Source).
2. Right-click the Audio Source component and click Localize.
3. Expand the Localized Asset Reference field.
4. Select the My Assets table from the Table Collection dropdown.
5. Click Add Table Entry and change the name to National Anthem.
6. Drag and drop the audio clips into the correct Locale fields.

7. String Localization: Create a String Table Collection

To create a String Table, open the New Table Collection tab, provide a name and click Create String Table Collection. To add an entry to the table press the Add New Entry button and give it a name.

Enable the Smart option to mark the entry as a Smart String. In this example we will use the Smart String reflection and plural features to print out a variable from the following script:

using UnityEngine;

public class Apples : MonoBehaviour
{
    public int appleCount = 1;
}

8. String Localization: Use String Table Entries

To add a UI Text element to the Scene, go to GameObject > UI > Text.

Right-click the Text component and select the Localize option. Unity adds a Localize String component and automatically configures it for the GameObject it is attached to. If the Text component contains a string value that is also in a String Table, then Unity automatically assigns this during the setup. If it does not, you can assign a value using the String Reference field pop-up. Add a reference to tge GameObject that contains the Apples component.

9. Build Preview and configuration

The Addressables player content must be built in order to use the localized assets in the player. This can be done through the Addressables window Window/Asset Management/Addressable Assets by clicking Build/Build Player Content. The Addressables window can also be used to control how the assets will be packaged and hosted(such as local storage or via a remote web server).
