PlayerID (Civ5 Type)

This page is a part of the Lua and UI Reference (Civ5).

The PlayerID pseudo-type is actually a regular integer. Pseudo-types do not exist in Lua, they only serve a documentation purpose on the wiki!

Usage

• You can get a player's ID through Player.GetID().
• There is a global Players table that stores all players. Keys are the players' ID and values are Player instances.
• The majors civs ID start at 0, up to 21. The minor civs ID start at 22, up to 62. The barbarians always have the ID 63.
• Those numbers may change in the future, so use the constants defined in GameDefines (see the constants section below) rather than hard-coded values.

How to retrieve a Player object from an ID:

local pPlayer = Players[playerID]

Enumerating players

Before you invoke a method on a player, ensure that IsEverAlive is true, otherwise Civilzation V will crash. Do not use IsAlive: while it may work sometimes, it does not always prevent a crash.

for id, player in pairs(Players) do
	if player:IsEverAlive() then
		print(id, player:GetName())
	end
end

On a map with two players and two city states this will produce the following output:

0   Wu Zetian
1   Genghis Khan
22  Monaco
23  Geneva
24  Warsaw
63  Barbarian

Built-in constants

You can also use the built-in constants: GameDefines.MAX_PLAYERS (64), GameDefines.MAX_CIV_PLAYERS (63), GameDefines.MAX_MAJOR_CIVS (22) and GameDefines.MAX_MINOR_CIVS (41). See also GameDefines
The following example enumerates major civs only:

for i = 0, GameDefines.MAX_MAJOR_CIVS - 1 do
	if Players[i]:IsEverAlive() then
		print(i, Players[i]:GetName())
	end
end

Code snippets

Here is a function to get a player by its CivilizationType. We then use it to print Wu Zeitan's name.

function GetPlayerByCivilization(civilizationType)
	for _, pPlayer in pairs(Players) do
		if pPlayer:GetCivilizationType() == civilizationType then 
			return pPlayer
		end
	end
end

local chineseCivilizationType = GameInfos.Civilizations.CIVILIZATION_CHINA.ID
local chinesePlayer = GetPlayerByCivilization(chineseCivilizationType)
print(chinesePlayer:GetName())	-- print "Wu Zeitan"
