Some of these functions return proxy tables. Writes to fields marked &quot;read-only&quot; are ignored. The '''__cfg''' fields return plain tables; in particular, writes do not modify the original object, and reads return the values from the time the dump was performed.<br /> <br /> Some helper functions are provided by the '''lua/helper.lua''' library. They are stored inside a table that is returned when loading the library with [[LuaWML:Files#wesnoth.require|wesnoth.require]].<br /> <br /> &lt;syntaxhighlight lang='lua'&gt;<br /> helper =

===<br /> <br /> If you take a look at Wesnoth's own lua files, you might find some undocumented functions use in the implementations of WML tags. Where possible, you should avoid using them, as they might be changed or removed with no compatibility for further releases. Instead, use the corresponding wml tags (in lua you can use &lt;tt&gt;wesnoth.wml_actions.tag_name(cfg)&lt;/tt&gt;, though keep in mind that this won't substitute variables in the config).<br /> <br /> If uncertain whether an undocumented feature is safe to use, ask on the forums, Discord, or IRC. It may turn out that someone simply forgot to add it to the wiki.<br /> <br /> * wesnoth.redraw<br /> * wesnoth.set_menu_item<br /> * wesnoth.clear_menu_item<br /> * wesnoth.modify_ai<br /> * wesnoth.print<br /> * wesnoth.end_level<br /> <br /> [[Category:Lua Reference]]</div> Celtic Minstrel
