|
|
Description of formspec language to show your menu is in lua_api.txt
|
|
|
|
Callbacks
|
|
---------
|
|
engine.buttonhandler(fields): called when a button is pressed.
|
|
^ fields = {name1 = value1, name2 = value2, ...}

|
|
^ event: "MenuQuit", "KeyEnter", "ExitButton" or "EditBoxEnter"
|
|
|
|

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 engine.start,engine.close,
|
|
engine.file_open_dialog
|
|
|
