LuaWML/Sides

This page describes the LuaWML functions and helpers for handling sides and villages.

wesnoth.get_side

Template:DevFeature1.11: This function is deprecated, use wesnoth.sides[i] instead of wesnoth.get_side(i).

wesnoth.sides

This is not a function but a table indexed by side numbers. Its elements are proxy tables with these fields:

• side: the side number
• gold, village_gold, base_income: integers (read/write)
• total_income: integer (read only)
• objectives, user_team_name: translatable strings (read/write)
• objectives_changed: boolean (read/write)
• team_name: string (read/write)
• controller: string (read/write)

note: In networked multiplayer, the controller attribute is ambiguous. Be very careful or you have OOS errors.

• fog: boolean (read)
• shroud: boolean (read)
• hidden: boolean (read)
• name: string (read)
• color: string (read) Template:DevFeature1.11: also write
• __cfg: WML table (dump)

The metatable of these proxy tables appears as "side".

local team = wesnoth.sides[1]
team.gold = team.gold + 50
wesnoth.message(string.format("%d sides", #wesnoth.sides))

wesnoth.get_sides

Returns a table array containing proxy tables for these sides matching the passed StandardSideFilter.

--set gold to 0 for all sides with a leader
local sides = wesnoth.get_sides({ {"has_unit", { canrecruit = true }} })
for i,v in ipairs(sides) do
    v.gold = 0
end

wesnoth.get_village_owner

Returns the side that owns the village at the given location.

local owned_by_side_1 = wesnoth.get_village_owner(12, 15) == 1

wesnoth.set_village_owner

Gives ownership of the village at the given location to the given side (or remove ownership if none). Ownership is also removed if nil or 0 is passed for the third parameter, but no capture events are fired in this case. An optional 4th parameter (boolean true|false, default: false) can be passed determining whether to fire any capture events.

wesnoth.set_village_owner(12, 15, 1)

wesnoth.is_enemy

Returns true if side A is enemy of side B, false otherwise.

local enemy_flag = wesnoth.is_enemy(1, 3)

wesnoth.match_side

Matches a side against a given StandardSideFilter.

wesnoth.message(tostring(wesnoth.match_side(1, {{"has_unit", { type = "Troll" }}})))

wesnoth.get_starting_location

local loc = wesnoth.get_starting_location(1)
wesnoth.message(string.format("side 1 starts at (%u, %u)", loc[1], loc[2]))

helper.all_teams

Returns an iterator over teams that can be used in a for-in loop.

for team in helper.all_teams() do team.gold = 200 end
