This is a multilingual translation automation tool based on the Unity Localization plugin and the OpenAI API. This tool can automatically translate missing string entries in Unity Localization using OpenAI GPT, making multilingual support both simple and efficient.

1. Integration with Unity Localization: Automatically find untranslated items in the String Table Collection and sync the results back to the String Table.
2. Customize translation requirements: Use the Comment in the String Table Metadata to provide additional translation requirements for GPT, controlling translation result preferences.
3. Iterate on translation results: You can delete and retranslate unsatisfactory translation results at any time. You can also specify translation for a single item.

• In the Unity menu, go to Window > Package Manager.
• Click + and select Add package from git URL.
• Enter the following URL:

  https://github.com/redclock/UnityGPTLocalization.git#release
  

• Click Add to install.
• If your project does not use the Unity Localization plugin, the Unity Localization plugin will also be automatically installed.

• Go to https://platform.openai.com/api-keys to get your API Key.

Open the Tools > GPT Localization menu in Unity to open the GPT Localization window.

• If no String Table Collection exists, the window will prompt you to create one.
• If there is one, select a String Table Collection from the dropdown menu.
• For testing, you can create some incomplete entries in the String Table.
  • Incomplete means that at least one language has a translation and at least one language does not have a translation for an entry.

• The window will automatically list all entries with incomplete translations.
• Click Translate Selected to translate all selected entries.
• You can also click the Translate button for each entry to translate individually.
• After translation, check the String Table Editor to see that the results have been automatically filled in.
• If you are not satisfied with a result, you can delete it in the String Table Editor and then retranslate.

• Click Open Table Editor to open the String Table Editor.

• In the String Table Editor, adding a Comment can control translation result preferences.

• Click Edit Metadata for an entry.

  

• Adding a Comment in the Shared Entry Metadata can control the translation results for all target languages of this entry.

• Adding a Comment in the language-specific Metadata can control the translation result for this entry in a specific language.

• You can control translation results with natural language, such as:

  • The translation result should be more formal.
  • Use short words, no more than 3 words.
  • Japanese should avoid using Katakana as much as possible.
  • The word "Native" should be kept in English in the target language.
  • And so on.

• If you don't know how to write a Comment, you can use this GPT bot I made to help you write Comments.

• OpenAI API calls require payment.
• Translation results are not guaranteed to be accurate and require manual review.

This project is based on srcnalt/OpenAI-Unity: A Unity plugin that supports OpenAI API calls.
