    Function hooking without the overhead and complexities of ALS.

  • y_inline

    Inline functions.

  • y_malloc

    Dynamic memory allocation from the heap.

  • y_remote

  • y_jaggedarray

    Multi-dimensional arrays with different sizes for each row of the second dimension.

  • y_playerarray

    "/language" command for allowing a user to change their language.

  • y_extra_other

    "/commands" to list all commands, and "/help" to display help on a single command.

  • y_extra_users

    "/login" and "/register" for the user system.


Features relating directly to information that varies per-player.

    Stores collections of players, for example admin teams, factions, or gangs. Can control permissions for many other libraries.

  • y_languages

    What language a player is, and what languages are available.
