Details:
I don't know any usecases for it but i tought it was a funny idea:
One could add a [make_tag] tag which creates custom wml tags:
-- A tag to create new wml tags
wesnoth.wml_actions.make_tag = function(cfg)
local tagname = cfg.tagname
local command = helper.get_child(cfg, "command")
wesnoth.wml_actions[tagname] = function(args)
local old_args = wesnoth.get_variable("args")
wesnoth.set_variable("args", args)
wesnoth.wml_actions.command(command)
wesnoth.set_variable("args", old_args)
end
-- TODO: Use wesnoth.game_events.on_load/save to make those tags
persistent.
end
This could then be used for example like this:
[make_tag]
## triggers an advancement for the given unit (which shows an advancement
dialog)
name = "advance_unit"
[command]
[store_unit]
[filter]
x = "$args.x"
y = "$args.y"
[/filter]
## args variable will be cleared automatically
variable = "args.unit"
[/store_unit]
[set_variable]
name = "args.unit.experience"
add = "args.unit.max_experience"
[/set_variable]
[unstore_unit]
variable = "args.unit"
fire_event = yes
[/unstore_unit]
[/command]
[/make_tag]
[advance_unit]
x,y = 7,4
[/advance_unit]
[advance_unit]
x,y = 8,4
[/advance_unit]
[advance_unit]
x,y = 9,4
[/advance_unit]
