Examples

This example shows how a Localized String Event can be dynamically updated with a different localized string or new formatting data.

using UnityEngine.Localization;
using UnityEngine.Localization.Components;

public class LocalizeStringEventExample : MonoBehaviour
{
[Serializable]
public class CharacterData
{
   public string name;
   public string surname;
   public int age;
}

public CharacterData characterInfo = new CharacterData { name = "Guy", surname = "Threepwood", age = 17 };

public LocalizeStringEvent localizedStringEvent;
LocalizedString originalLocalizedString;

// Various ways to address a string table entry
public LocalizedString localizedString = new LocalizedString { TableReference = "My String Table Collection", TableEntryReference = "My Text 1" };
public string tableName = "My String Table Collection";
public string keyName = "My Text 2";
public long keyId = 123;

void Start()
{
   // Keep track of the original so we dont change localizedString by mistake
   originalLocalizedString = localizedStringEvent.StringReference;

   // Assuming the Localizing String is using Smart Format:
   // The string
   // "{name} {surname} is {age} years old"
   // would produce:
   // "Guy Threepwood is 17 years old"
   localizedStringEvent.StringReference.Arguments = new[] { characterInfo };

   // We can add a listener if we are interested in the Localized String.
   localizedStringEvent.OnUpdateString.AddListener(OnStringChanged);
}

void OnStringChanged(string s)
{
   Debug.Log($"String changed to `{s}`");
}

void OnGUI()
{
   if (GUILayout.Button("Change using LocalizedString"))
   {
       // We are assigning a new LocalizedString so will need to copy the arguments across
       localizedString.Arguments = localizedStringEvent.StringReference.Arguments;

       // Assign the new LocalizedString, this will trigger an update
       localizedStringEvent.StringReference = localizedString;
   }

   if (GUILayout.Button("Change using key name"))
   {
       // Restore the original LocalizedString in case we changed it previously.
       localizedStringEvent.StringReference = originalLocalizedString;

       // Assign a new Table and Entry. This will trigger an update.
       localizedStringEvent.StringReference.SetReference(tableName, keyName);

       // We could do this if we only wanted to change the entry but use the same table
       // localizedStringEvent.StringReference.TableEntryReference = keyName;
   }

   if (GUILayout.Button("Change using key id"))
   {
       // Restore the original LocalizedString in case we changed it previously.
       localizedStringEvent.StringReference = originalLocalizedString;

       // Assign a new Table and Entry. This will trigger an update.
       localizedStringEvent.StringReference.SetReference(tableName, keyId);

       // We could do this if we only wanted to change the entry but use the same table
       // localizedStringEvent.StringReference.TableEntryReference = keyId;
   }

   if (GUILayout.Button("Increase Age"))
   {
       characterInfo.age++;

       // Force the string to refresh
       localizedStringEvent.RefreshString();
   }

   if (GUILayout.Button("Decrease Age"))
   {
       characterInfo.age--;

       // Force the string to refresh
       localizedStringEvent.RefreshString();
   }
}
