Translating Heroes III data

VCMI allows translating game data into languages other than English. In order to translate Heroes III in your language easiest approach is to:

• Copy existing translation, such as English translation from here: https://github.com/vcmi-mods/h3-for-vcmi-englisation (delete sound and video folders)
• Rename mod to indicate your language, preferred form is "(language)-translation"
• Update mod.json to match your mod
• Translate all texts strings from game.json, campaigns.json and maps.json
• Replace images in data and sprites with translated ones (or delete it if you don't want to translate them)
• If unicode characters needed for language: Create a submod with a free font like here: https://github.com/vcmi-mods/vietnamese-translation/tree/vcmi-1.4/vietnamese-translation/mods/VietnameseTrueTypeFonts

If you have already existing Heroes III translation you can:

• Install VCMI and select your localized Heroes III data files for VCMI data files
• Launch VCMI and start any map to get in game
• Press Tab to activate chat and enter '/translate'

This will export all strings from game into Documents/My Games/VCMI/extracted/translation/ directory which you can then use to update json files in your translation.

To export maps and campaigns, use '/translate maps' command instead.

Translating VCMI data

VCMI contains several new strings, to cover functionality not existing in Heroes III. It can be roughly split into following parts:

• In-game texts, most noticeably - in-game settings menu.
• Game Launcher
• Map Editor
• Linux specific
• Android Launcher

Before you start, make sure that you have copy of VCMI source code. If you are not familiar with git, you can use Github Desktop to clone VCMI repository.

Translation of in-game data

In order to translate in-game data you need:

• Add section with your language to <VCMI>/Mods/VCMI/mod.json, similar to other languages
• Copy English translation file in <VCMI>/Mods/VCMI/config/vcmi/english.json and rename it to name of your language. Note that while you can copy any language other than English, other files might not be up to date and may have missing strings.
• Translate copied file to your language.

After this, you can set language in Launcher to your language and start game. All translated strings should show up in your language.

Translation of Launcher and Editor

VCMI Launcher and Map Editor use translation system provided by Qt framework so it requires slightly different approach than in-game translations:

• Install Qt Linguist. You can find find standalone version here: https://download.qt.io/linguist_releases/
• Open <VCMI Sources>/launcher/translation/ directory, copy english.ts file and rename it to your language
• Launch Qt Linguist, select Open and navigate to your copied file
• Select any untranslated string, enter translation in field below, and click "Done and Next" (Ctrl+Return) to navigate to next untranslated string
• Once translation has been finished, save resulting file.

Translation of Map Editor is identical, except for location of translation files. Open <VCMI Sources>/editor/translation/ instead to translate Map Editor

Translation of Linux specific files

Translation of AppStream metainfo

The AppStream metainfo file is used for Linux software centers.

It can be translated using a text editor or using jdAppStreamEdit:

• Install jdAppStreamEdit
• Open <VCMI>/launcher/eu.vcmi.VCMI.metainfo.xml
• Translate and save the file

Desktop file

• Edit <VCMI>/launcher/vcmilauncher.desktop and <VCMI>/launcher/vcmieditor.desktop
• Add GenericName[xyz] and Comment[xyz] with your language code and translation

Translation of Android Launcher

• Copy <VCMI>/android/vcmi-app/src/main/res/values/strings.xml to <VCMI>/android/vcmi-app/src/main/res/values-xyz/strings.xml (xyz is your language code)
• Translate this file

Submitting changes

Once you have finished with translation you need to submit these changes to vcmi team using git or Github Desktop

• Commit all your changed files
• Push changes to your forked repository
• Create pull request in VCMI repository with your changes

If everything is OK, your changes will be accepted and will be part of next release.

Translating mods

Exporting translation

If you want to start new translation for a mod or to update existing one you may need to export it first. To do that:

• Enable mod(s) that you want to export and set game language in Launcher to one that you want to target
• Launch VCMI and start any map to get in game
• Press Tab to activate chat and enter '/translate'

After that, start Launcher, switch to Help tab and open "log files directory". You can find exported json's in 'extracted/translation' directory.

If your mod also contains maps or campaigns that you want to translate, then use '/translate maps' command instead.

Translating mod information

In order to display information in Launcher in language selected by user add following block into your mod.json:

	"<language>" : {
		"name" : "<translated name>",
		"description" : "<translated description>",
		"author" : "<translated author>",
		"translations" : [
			"config/<modName>/<language>.json"
		]
	},

However, normally you don't need to use block for English. Instead, English text should remain in root section of your mod.json file, to be used when game can not find translated version.

Tranlating in-game strings

After you have exported translation and added mod information for your language, copy exported file to <mod directory>/Content/config/<mod name>/<language>.json.

Use any text editor (Notepad++ is recommended for Windows) and translate all strings from this file to your language

Developers documentation

Adding new languages

In order to add new language it needs to be added in multiple locations in source code:

• Generate new .ts files for launcher and map editor, either by running lupdate with name of new .ts or by copying english.ts and editing language tag in the header.
• Add new language into lib/Languages.h entry. This will trigger static_assert's in places that needs an update in code
• Add new language into json schemas validation list - settings schema and mod schema
• Add new language into mod json format - in order to allow translation into new language

Also, make full search for a name of an existing language to ensure that there are not other places not referenced here

Updating translation of Launcher and Map Editor to include new strings

At the moment, build system will generate binary translation files (.qs) that can be opened by Qt. However, any new or changed lines will not be added into existing .ts files. In order to update .ts files manually, open command line shell in mapeditor or launcher source directories and execute command

lupdate -no-obsolete * -ts translation/*.ts

This will remove any no longer existing lines from translation and add any new lines for all translations. If you want to keep old lines, remove -no-obsolete key from the command There may be a way to do the same via QtCreator UI or via CMake, if you find one feel free to update this information.

Updating translation of Launcher and Map Editor using new .ts file from translators

Generally, this should be as simple as overwriting old files. Things that may be necessary if translation update is not visible in executable:

• Rebuild subproject (map editor/launcher).
• Regenerate translations via lupdate -no-obsolete * -ts translation/*.ts
