Internationalizing games
|
|
========================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
Sería excelente que el mundo hablara solo un idioma. Unfortunately for
|
|
us developers, that is not the case. While not generally a big
|
|
requirement when developing indie or niche games, it is also common
|
|
that games going into a more massive market require localization.
|
|
|
|
Godot offers many tools to make this process more straightforward, so
|
|
this tutorial is more like a collection of tips and tricks.
|
|
|
|
Localization is usually done by specific studios hired for the job and,
|
|
despite the huge amount of software and file formats available for this,
|
|
the most common way to do localization to this day is still with
|
|
spreadsheets. The process of creating the spreadsheets and importing
|
|
them is already covered in the :ref:`doc_importing_translations` tutorial, so this
|
|
one could be seen more like a follow up to that one.
|
|
|
|
|
|
.. note:: We would be using the offical demo as an example, you can download it in the AssetLib: https://godotengine.org/asset-library/asset/134 or find it in the demo_projects/gui/translation
|
|
|
|
Configuring the imported translation
|
|
------------------------------------
|
|
|
|
The translations can get updated and re-imported when they change, but
|
|
they still have to be added to the project. This is done in Project
|
|
> Project Settings > Localization:
|
|
|
|
.. image:: img/localization_dialog.png
|
|
|
|
This dialog allows to add or remove translations project-wide.
|
|
|
|
Localizing resources
|
|
--------------------
|
|
|
|
It is also possible to instruct Godot to open alternative versions of
|
|
assets (resources) depending on the current language. For this the
|
|
"Remaps" tab exists:
|
|
|
|
.. image:: img/localization_remaps.png
|
|
|
|
Select the resource to be remapped, and the alternatives for each
|
|
locale.
|
|
|
|
Converting keys to text
|
|
-----------------------
|
|
|
|
Some controls such as :ref:`Button <class_Button>`, :ref:`Label <class_Label>`,
|
|
etc. will automatically fetch a translation each time they are set a key
|
|
instead of a text. For example, if a label is assigned
|
|
"MAIN_SCREEN_GREETING1" and a key to different languages exists in the
|
|
translations, this will be automatically converted.
|
|
|
|
For code, the :ref:`Object.tr() <class_Object_tr>`
|
|
function can be used. This will just look-up the text into the
|
|
translations and convert it if found:
|
|
|
|
::
|
|
|
|
level.set_text(tr("LEVEL_5_NAME"))
|
|
status.set_text(tr("GAME_STATUS_" + str(status_index)))
|
|
|
|
Making controls resizable
|
|
--------------------------
|
|
|
|
The same text in different languages can vary greatly in length. For
|
|
this, make sure to read the tutorial on :ref:`doc_size_and_anchors`, as having
|
|
dynamically adjusted control sizes may help.
|
|
:ref:`Container <class_Container>` can be useful, as well as the multiple options in
|
|
:ref:`Label <class_Label>` for text wrapping.
|
|
|
|
TranslationServer
|
|
-----------------
|
|
|
|
Godot has a server for handling the low level translation management
|
|
called the :ref:`TranslationServer <class_TranslationServer>`.
|
|
Translations can be added or removed during run-time, and the current
|
|
language be changed too.
|
|
|
|
Command line
|
|
------------
|
|
|
|
Language can be tested when running Godot from command line. For
|
|
example, to test a game in french, the following arguments can be
|
|
supplied:
|
|
|
|
::
|
|
|
|
c:\MyGame> godot -l fr
|
|
|
|
Translating the project name
|
|
----------------------------
|
|
|
|
The project name becomes the app name when exporting to different
|
|
operating systems and platforms. To specify the project name in more
|
|
than one language, create a new setting application/name in the project
|
|
settings dialog and append the locale identifier to it. For example:
|
|
|
|
.. image:: img/localized_name.png
|
|
|
|
As always, If you don't know the code of a language or zone, :ref:`check the
|
|
list <doc_locales>`.
