|
|
Introduction
|

-------------
|
|
|
|
The main menu is defined as a formspec by Lua in builtin/mainmenu/
|
|
Description of formspec language to show your menu is in lua_api.txt
|
|
|
|
|
|
Callbacks
|
|
---------
|
|
|
|
core.button_handler(fields): called when a button is pressed.

Async
|

|
|
^ the result of async_job is passed to this function
|
|
|
|
Limitations of Async operations
|
|
-No access to global lua variables, don't even try
|
|
-Limited set of available functions
|
|
e.g. No access to functions modifying menu like core.start,core.close,
|
|
core.show_path_select_dialog
|
|
|
|
|
|
Background music
|
|
----------------
|
|
|
|
The main menu supports background music.
|
|
It looks for a `main_menu` sound in `$USER_PATH/sounds`. The same naming
|
|
conventions as for normal sounds apply.
|
|
This means the player can add a custom sound.
|
|
It will be played in the main menu (gain = 1.0), looped.
|
