Google Spreadsheets and local CSV files can be linked as external sources for easy editing and sharing of translations. With a single click your game will be up to date with the latest changed.
Once your game is deployed, it will still download from the spreadsheets the latest changes and any new language. Allowing you to fix typos and make changes without releasing a new version of the game.
Right from inside the editor all Terms can be listed and modified. Changing the translations and adding new languages.
There are lot of visual tips for highlighting localization errors and tooltips to explain each feature.
Any term or language can be automatically translated by clicking a single button or by linking the language source with the Google Spreadsheet’s translation features.
Using automatic translations you can support any language from the very start and correct it later on.
Right to Left
Automatically fixes the translations to correctly display Right to Left languages.
This is an automatic process and will happen out-of-the-box for all RTL languages like Arabic, etc.
Provides configurable callbacks for correct concatenation and replacements.
That allows concatenation for adding names and values to the translation while following the language rules as the word order changes
based on the language.
Other modifications can include making the text all Capitals, lower case, etc.
