getPlayerCount

[JuniorMelo]

hello, I wanted to know if I can use this function this way ?

getPlayerCount, dimension 2

====count players in dimension 2====

addEvent("text", true) 
addEventHandler("text", getRootElement(), 
function() 
    for k,v in ipairs(getElementsByType("player")) do 
        if getElementDimension ( v ) == 2 then 
            local Count = getPlayerCount(v) 
            setElementData(source,"players",Count) 
        end 
    end 
end)

Add a variable for player count. Like that,

addEvent("text", true) 
addEventHandler("text", getRootElement(), 
function() 
   local playerCount = getPlayerCountInDimension( 2 ) 
   if playerCount then 
         setElementData(source,"players",Count) 
   end 
end) 
  
function getPlayerCountInDimension( dimID ) 
    local counter = 0 
    for k,v in ipairs(getElementsByType("player")) do 
        if getElementDimension ( v ) == dimID then 
            counter = counter + 1 
        end 
    end 
    return counter 
end

I think you wanted to do more like this:

addEvent("text", true) 
addEventHandler("text", getRootElement(), 
function() 
    local count = 0 
    for k, v in ipairs(getElementsByType("player")) do 
        if getElementDimension ( v ) == 2 then 
            count = count + 1 
        end 
    end 
    setElementData(source, "players", count) 
end) 

Or as a function extension:

local _getPlayerCount = getPlayerCount 
function getPlayerCount( dim ) 
    if dim == nil then return _getPlayerCount() end 
    local count = 0 
    for k, p in ipairs(getElementsByType("player")) do 
        if getElementDimension(p) == dim then 
            count = count + 1 
        end 
    end 
end 

That you will then call like this:

addEvent("text", true) 
addEventHandler("text", getRootElement(), 
function() 
    local count = getPlayerCount(2) 
    setElementData(source, "players", count) 
end) 

But your code doesn't make sense as it looks like you want to output a message to all players in a specific dimension ? In that case, getting the numbers of players in that dimension won't help you. You will need the list of the players in that dimension instead:

function getPlayersInDimension( dim ) 
    local players = {} 
    for k, p in ipairs(getElementsByType("player")) do 
        if getElementDimension(p) == dim then 
            table.insert(players, p) 
        end 
    end 
    return players 
end 

And then use it like this:

addEvent("text", true) 
addEventHandler("text", getRootElement(), 
function( msg ) 
    local players = getPlayersInDimension(2) 
    for k, p in ipairs(players) do 
        outputChatBox(p, msg) 
    end 
end) 

Don't forget to send the text message as argument of your triggerServerEvent.

More informations on what you try to achieve would be appreciated.
