[Help] localPlayer passing failed

[steadyfi]

Hi.

I have a little problem with passing the localPlayer variable from Client-Side to Server-Side with a triggerServerEvent()

Client-Side Code:

local localPlayer = getLocalPlayer() 
function teamSetText() 
    team = getPlayerTeam(getLocalPlayer()) 
    if team then 
        guiSetText(teamNameLabel, "Team: "..getTeamName(getPlayerTeam(getLocalPlayer()))) 
        guiSetText(playerCountLabel, "Players: "..countPlayersInTeam(getPlayerTeam(getLocalPlayer()))) 
        triggerServerEvent("openteams.getTeamLeader", localPlayer) 
    end 
end 

Server-Side Code:

function giveClientLeaderName(localPlayer) 
    local team = getPlayerTeam(localPlayer) 
    if team then 
        --XML 
            local xmlFile = xmlLoadFile("teams.xml", "root") 
            local children = xmlNodeGetChildren(xmlFile) 
            for i,node in pairs(children) do 
                local attribute = xmlNodeGetAttribute(node, "name") 
                if attribute == getTeamName(team) then 
                    local leaderName = xmlNodeGetAttribute(team, "leader") 
                end 
            end 
            xmlUnloadFile(xmlFile) 
        --END XML 
        triggerClientEvent("openteams.getTeamLeader.serverGave", leaderName) 
    end 
end 
addEvent("openteams.getTeamLeader", true) 
addEventHandler("openteams.getTeamLeader", getRootElement(), giveClientLeaderName) 

Error:

It says it expected the player element but it got nil (it wasn't passed)

The second parameter of triggerServerEvent is a baseElement. If you pass the localPlayer in triggerServerEvent as the second argument, it will be sent as the predefined variable source, so in giveClientLeaderName, 'source' is the localPlayer.

This is discouraged though as it is vulnerable to event-faking. Read the wiki page for more info.

Thank you.

By the way, could you give me the link to the wiki page ?

In any Lua code on the forums you can click the functions which will direct you to its respective wiki pages.

Also,

1. Security isn't important, all I do is passing localPlayer Server-Side, getting a string, and passing it back Client-Side

2. It now says an event is not triggerable.

Client Side:

local localPlayer = getLocalPlayer() 
function teamSetText() 
    team = getPlayerTeam(getLocalPlayer()) 
    if team then 
        guiSetText(teamNameLabel, "Team: "..getTeamName(getPlayerTeam(getLocalPlayer()))) 
        guiSetText(playerCountLabel, "Players: "..countPlayersInTeam(getPlayerTeam(getLocalPlayer()))) 
        triggerServerEvent("openteams.getTeamLeader", localPlayer) 
    end 
end 
  
function serverGaveLeaderName(leaderName) 
    team = getPlayerTeam(getLocalPlayer()) 
    if team then 
        guiSetText(teamNameLabel, "Leader: "..tostring(leaderName)) 
    end 
end 
addEvent("openteams.getTeamLeader.serverGave") 
addEventHandler("openteams.getTeamLeader.serverGave", getRootElement(), serverGaveLeaderName) 

Server-Side:

function giveClientLeaderName() 
    local team = getPlayerTeam(source) 
    if team then 
        --XML 
            local xmlFile = xmlLoadFile("teams.xml", "root") 
            local children = xmlNodeGetChildren(xmlFile) 
            for i,node in pairs(children) do 
                local attribute = xmlNodeGetAttribute(node, "name") 
                if attribute == getTeamName(team) then 
                    local leaderName = xmlNodeGetAttribute(node, "leader") 
                end 
            end 
            xmlUnloadFile(xmlFile) 
        --END XML 
        triggerClientEvent("openteams.getTeamLeader.serverGave", root, leaderName) 
    end 
end 
addEvent("openteams.getTeamLeader", true) 
addEventHandler("openteams.getTeamLeader", getRootElement(), giveClientLeaderName) 

Error:

Server triggered clientside event openteams.getLeaderName.serverGave, but event is not marked as remotly triggerable

[Bonsai]

addEvent("openteams.getTeamLeader.serverGave") 

needs to be

addEvent("openteams.getTeamLeader.serverGave", true) 

[steadyfi]

addEvent("openteams.getTeamLeader.serverGave") 

needs to be

addEvent("openteams.getTeamLeader.serverGave", true) 

Thank you.
