String Table

Text localisation

The LuaUtils component provides support for simple text localisation.

1. Define your language strings in a JSON file and save it in the project assets folder.
2. Add a LuaEnvironment component to your scene - e.g. Tools > Fungus > Create > LuaEnvironment
3. In the LuaUtils component, set the String Table property to reference your JSON file asset.
4. Use the {$VarName} syntax to subsitute a localised string anywhere that string substitution is supported. e.g. in a Lua script:

say("{$hello_world}")

You can use the {$VarName} syntax anywhere that variable subsitution is supported. This includes:

• Say command
• Menu command
• Set Text command
• Write command
• Conversation command
• Character object - character name
• Debug Log command
• Load Variable command - save key
• Save Variable command - save key
• Delete Save Key command

You can also extend the Fungus string substitution system with your own components. Implement the StringSubstituter.ISubstitutionHandler interface in a Monobehavior subclass and then return the modified string from SubstituteStrings().

JSON Format

This is an example of the JSON format for the string table. To use this localised string, you would use the {$hello_world} tag.

{
	"hello_world" : {
		"en" : "Hello world!",
		"fr" : "Bonjour le monde!",
		"de" : "Hallo Welt!"
	},
	"goodbye_world" : {
		"en" : "Goodbye world!",
		"fr" : "Au revoir monde!",
		"de" : "Auf Wiedersehen Welt!"
	}
}

Lua Functions

These Lua functions are available for working with the string table.

-- Set active language for string table
setlanguage(languagecode)

-- Get a named string from the string table
getstring(key)

-- Substitutes variables and localisation strings into a piece of text
-- e.g. v = 10, "Subbed value is [$v]" => "Subbed value is 10"
sub(text)
