Objectives

• To get an overview of the different types of gameassets that need to be localized

• To understand the different approaches of publishing localized games

• To learn how to handle issues with the localization process

Globalization & Localization

• When you limit your product's availability to only one language, you limit your potential customer base to a fraction of our world’s 6.5 billion population.

• If you want your applications to reach a global audience, cost-effective localization of your product is one of the best and most economical ways to reach more customers.

Globalization & Localization

• Globalization is the design and development of applications that perform in multiple locations. For example, globalization supports localized user interfaces and regional data for users in different cultures.

• Localization is the translation of application resources into localized versions for the specific cultures that the application supports.

Localization Process

1. Export localization file with1. Localization keys

2. Source language

2. Convert from game format to CSV and XLS.

3. Localize file by adding target language.

4. Convert from XLS to CSV and game format.

5. Import localization file with1. Localization keys

2. Target language

Gotcha!

Ensure you are using the proper encoding (e.g. UTF-8) for all text

files (e.g. XML, CSV)!

CSV Export

13 / 28

All CSV files should use the same format, e.g. character set, field delimiters and text delimiters.

Numbers in Texts

• Use ordered references in localized strings that are replaced in code:

“Deals {0} damage and stuns the target for {1} seconds.”

• Localize your string by replacing the key by the localized text, and replace all placeholders after.

• Unordered placeholders, such as %d might not be enough, as some languages change the word order!

Handling The Mess

• Missing localization keys• Debug builds should show the raw localization key if it

fails to lookup a localized string. This helps your QA to tell you the exact missing key.

• Release builds should fallback to a default language.

• Duplicate localization keys• Your tools should detect and report duplicate

localization keys immediately on import.

• Otherwise, you’ll be spending a lot of time tracking down that localization bug that is caused by an overridden key – trust me.

15 / 28

Subsequent Changes

• Keys that are added or modified after the spreadsheets have been sent out to the localization studio must be highlighted

16 / 28

Subsequent Changes

• Try and collect all last-minute changes so you don’t have to bother your localization studio more than twice

17 / 28

Hint

All tools should order your localization keys by name.

This will help tremendously with source control.

UI Design Best Practice

• Avoid using absolute positions and fixed sizes to lay out content; instead, use relative or automatic sizing.

• Provide extra space in margins because localized text often requires more space.

19 / 28

Localization Briefing

• Have your localization people actually play the game before localizing it

• Provide additional information, such as character sheets, where necessary

20 / 28

Localization Tools

• Allow your team to change the language in-game, if possible.

• Provide a local localization override file, if possible.• This way, your team can check changed texts

immediately without having to rebuild the game.

21 / 28

Localization Testing

• Check each localized version thoroughly for• Shrinked texts

• Cut texts

• Overlapping texts

• Strange line breaks

• Typos

22 / 28

Packaging

Option 1: All languages available

• Required for some platforms, such as mobile

• User can switch language any time

• Package size increases linearly with number of languages

23 / 28

Packaging

Option 2: Language packs

• Required for some platforms, such as Steam

• User needs to download additional files for switching the language

• Package size is always the same

24 / 28

Live Games

• All of this assumes you’re running a stand-alone game, such as Windows or iPad

• Live games (e.g. browser, client-server) will require you to update both backend and frontend at the same time – for all available languages – unless you have a sophisticated versioning system in place.

25 / 28

Localized Images

• Usually boils down to signs and posters shown in the game world

• Avoid wherever possible!• Requires artists to fire up Photoshop and localize by

hand

26 / 28Poster in Bioshock Infinite

Localized Videos

• If you’re lucky, this boils down to speech of the video

• In this case, you can use Matroska Media Containers which split up your video into• Video (MKV)

• Audio (MKA)

• Subtitles (MKS)

• Otherwise, you’ll be forced to provide videos for each language• Only huge companies like Blizzard make that effort
