[HELP] attempt to call global 'TriggerClientEvent' (a nil value)

[CouldnoT]

Hello kind reader, i hope you have a great day!

I'm making my first steps to create a login panel, and I just started learning the Gui basics, but I'm failing to Export the Gui from client side.

Here is my script ( it's not complicated at all :

Client side : 

local login = {};

function login_show()
    login[1] = guiCreateWindow (0, 0, 0.5, 0.4, "Information", true);  
    login[2] = guiCreateTabPanel (0, 0.1, 1, 1, true, login[1]);      
    login[4] = guiCreateTab("Map Information", login[3]);                
    login[5] = guiCreateTab("Help", login[4]);                          

    -- adds a label (text) to each tab
    guiCreateLabel(0.02, 0.04, 0.94, 0.2, "This is information about the current map", true, login[4]);
    guiCreateLabel(0.02, 0.04, 0.94, 0.92, "This is help text.", true, login[5]);
end;
addEvent("loginshow", true); 
addEventHandler("loginshow", root, login_show); 



function login_delete()
    for i,k in ipairs(login) do
        if login[i] then
            guiSetVisible(login[i], false);
        end;
    end;      
end;
addEvent("logindelete", true); 
addEventHandler("logindelete", root, login_delete);  

 

Serverside : 

 

function LoginPanelShow()
	TriggerClientEvent(Player, "loginshow");
end

function LoginPanelDelete()
	TriggerClientEvent(Player, "logindelete");
end

addCommandHandler("test1", LoginPanelShow);
addCommandHandler("test2", LoginPanelDelete);

 

I greatly thank you for your attention!

Hi.

1) TriggerClientEvent is not a valid function, correct is triggerClientEvent.
2) Player variable is not defined (so it's nil) in LoginPanelShow and LoginPanelDelete.
3) Third argument is missing in triggerClientEvent, check syntax on wiki.

 

-- CLIENT

local login = {};

function login_show()
    login[1] = guiCreateWindow (0, 0, 0.5, 0.4, "Information", true);  
    login[2] = guiCreateTabPanel (0, 0.1, 1, 1, true, login[1]);      
    login[4] = guiCreateTab("Map Information", login[3]);                
    login[5] = guiCreateTab("Help", login[4]);                          

    -- adds a label (text) to each tab
    guiCreateLabel(0.02, 0.04, 0.94, 0.2, "This is information about the current map", true, login[4]);
    guiCreateLabel(0.02, 0.04, 0.94, 0.92, "This is help text.", true, login[5]);
end;
addEvent("loginshow", true); 
-- listen to those events, which source is 'resourceRoot'
addEventHandler("loginshow", resourceRoot, login_show); 



function login_delete()
    for i,k in ipairs(login) do
        if login[i] then
            guiSetVisible(login[i], false);
        end;
    end;      
end;
addEvent("logindelete", true); 
addEventHandler("logindelete", resourceRoot, login_delete);  

-- SERVER

-- addCommandHandler pass the player's element to function at first argument. (only on server side, check addCommandHandler's syntax on wiki)
function LoginPanelShow(Player)
  	-- send this trigger to 'Player', and use 'resourceRoot' as source of the event
	triggerClientEvent(Player, "loginshow", resourceRoot);
end

function LoginPanelDelete(Player)
	triggerClientEvent(Player, "logindelete", resourceRoot);
end

addCommandHandler("test1", LoginPanelShow);
addCommandHandler("test2", LoginPanelDelete);
