Immovables are entities not connected to a road that a tribe can own, for example a corn field or a ship under construction.

Tribe Immovables are defined in data/tribes/immovables/<immovable_name>/init.lua.


This function adds the definition of a tribe immovable to the engine.


table – This table contains all the data that the game engine will add to this immovable. It contains the following entries:

name: A string containing the internal name of this immovable.

descname: The translatable display name. Use pgettext to fetch the string.

helptext_script: The full path to the helptexts.lua script for this immovable. NOTE: Deprecated. Immovable helptexts have been shifted to tribes initialization in the current development version.

programs: A table with the programs that this immovable will perform, e.g. { "animate=idle duration:2m30s500ms",  "remove=" } (see Immovable Programs)

animations: A table containing all animations for this immovable.

For making the UI texts translateable, we also need to push/pop the correct textdomain.



dirname = path.dirname(__file__)

descriptions:new_immovable_type {
   name = "ashes",
   descname = pgettext("immovable", "Ashes"),
   anmation_directory = dirname,
   icon = dirname .. "menu.png",
   size = "small",
   programs = {
      main = {
         "animate=idle duration:45s",

   animations = {
      idle = {
         hotspot = { 40, 39 },


Help Texts

Each tribe immovable has a helptexts.lua script, which is located in the same directory as its init.lua script. The function in this file returns texts that are used for the immovable by the Tribal Encyclopedia.


Returns a localized string with a helptext for this immovable type.


tribe (string) – the name of the tribe to fetch this helptext for.

This function works exactly the same as ware_helptext.
