Best practices - DLC for Chapters and Language

In I2L, there are two types of language source: Global Sources and Local Sources

Global Sources are loaded automatically by the plugin and are can be accessed from any scene. The best example of this is the I2Languages.prefab.
To create other Global Sources, you have to duplicate the I2Languages.prefab (or a create a new gameobject, add a LanguageSource component and save that as a prefab), then you have to tell I2L that prefab should be loaded at startup. Which you do by adding the name of the prefab to the GlobalSources array in the LocalizationManager.cs line 207Global Sources, need to included in the Build



On the hand, Local Sources, are part of the Scenes (created by adding a LanguageSource component to any of your Scene Objects, but not creating a prefab out of it). An example of Local sources are the sources included in each Example Scene in I2L.
These sources, are only accessible while the scene is loaded, and its meant to be localization that will be used only in that scene. I'm using Local Sources in the Example Scenes, as that allows me to have separated translations for each scene and changing one doesn't affect the other.

Because of this, they are great for AssetBundles. Just add a LanguageSource component to any scene in your bundle and the translations will be available for that scene.
Alternatively, you can create an scene just for the LanguageSource, and load it additively whenever you use the content from the AssetBundle.

If you don't like handling the sources inside Scenes, another alternative is to have the source as a prefab in the bundle, and then, once you download the bundle, call LocalizationManager.AddSource( source )

Hope that helps,
