New feature: generic on_changed event

English Lua Scripting
1

Hi,

Lua scipting just got more powerful!

Some objects have events like on_value_changed or on_aspect_changed, this is very useful for building scripts, but also limited as it is only possible to act on changes for events that existed.

Traintastic now supports the on_changed on every object! With a single line of Lua it is now possible to act on the changes of one, multiple of all properties of an object :slight_smile:

A few examples:

-- Single property:
signal.on_changed("aspect", function(aspect)
  log.debug("Signal aspect: ", aspect)
end)

-- Multiple properties:
turnout.on_changed({"position", "reserved_position"}, function(value, object, name)
  log.debug(object.name, name, value)
end)

-- All properties:
block.on_changed(function(value, object, name)
  log.debug(object.name, name, value)
end)

See the Lua events manual page for more detailed information.

Happy hacking!
