jloc

Localisation library for Gamemaker Studio 2, created by @Katipo007

Usage

1. Import extension to your project.
2. Add localisation .json files to your project as "Included Files" (eg: localisation/english.json)
3. (optional) If you wish to store your localisation files somewhere other than /localisation/ call jloc_set_directory() with the desired path, calling with -1 will reset to /localisation/.
4. Call jloc_load() with the desired language, eg: jloc_load("english")
5. You are now avaliable to call jloc_translate_* functions

Installation

Using Catalyst, the open-source package manager for GameMaker Studio 2:

catalyst require katipo007/jloc

Localisation File Format

Localisation files are defined in the JSON format, and the filenames use the .json extension.

{
    "lookup": "value",
    
    "sublevel": {
        ".": "SublevelValue",
        "lookup": "value2"
    }
}

After loading the above example file,

• jloc_translate("lookup") will return "value"
• jloc_translate("sublevel.lookup") will return "value2"
• jloc_translate("sublevel") will return "SublevelValue"
• jloc_translate("invalid.lookup") will return "invalid.lookup"

Replacements

jloc_translate_ext() and jloc_translate_ext_array() allow you to supply values to be inserted into the translated string via "%" tags.

Eg: A localisation value of "Hello, %1!", when called with jloc_translate_ext("<lookupId>", "world") will return "Hello, world!". jloc_translate("<lookupId>") would return "Hello, %1!".

FAQ

• What if a value is not found for a localisation lookup?
  • The lookup string will be returned. Eg: jloc_translate("invalid.lookup") will return "invalidLookup".
• Supported platforms
  • Because it is written completely in GML it will work on all export platforms. The only exception is HTML5, where the jloc_get_languages() function will not work due to Gamemaker limitations.
• My localisation file is not loading
  • jloc_load() returns an error code in the event something went wrong, you can compare the returned value against the extension macros jloc_error_no_error, jloc_error_cant_find_file and jloc_error_read_error. jloc_error_read_error signifies that the JSON file could not be parsed correctly and it should be checked for formating errors (gamemaker doesn't provide functionality to check why it failed.) It is often due to a missing ,.
