This function returns the number of players currently connected to the server.

[[{{{image}}}|link=|]] Note: #getElementsByType("player") works the same as this function but also works client side unlike this function.

Syntax

int getPlayerCount ( )

OOP Syntax Help! I don't understand this!

Method: Player.getCount(...)


Returns

Returns the number of players connected to the server as an int.

Example

This example displays a chat message with the number of players connected to the server when a player joins or quits. 

function playerCount ( )
	outputChatBox ( "There are now " .. getPlayerCount() .. " players on this server!" )
end
addEventHandler ( "onPlayerJoin", root, playerCount )
addEventHandler ( "onPlayerQuit", root, playerCount )

Shared implementation of getPlayerCount

getElementsByType("player") returns a regular-indexed table with every player connected to the server, so by counting how many entries has the table (by using the # operator) we can archieve the same result as this function, but also clientside. However, it's more efficient to use the built-in function serverside. The next function replaces this function accordingly serverside and clientside to work on both.

Shared (client and server)
local originalGetPlayerCount = getPlayerCount -- Store the original getPlayerCount function to a variable

function getPlayerCount()
    -- If originalGetPlayerCount is defined, that means that this function is executed serverside.
    -- The next line returns the result of the original function if it's defined. If not, it counts the number of player elements (to also work clientside).
    return originalGetPlayerCount and originalGetPlayerCount() or #getElementsByType("player")
end
