If you are updating ESX, be sure to update the remaining scripts!

Instrukcja w języku Polskim znajduje się tutaj.

Required changes:

• es_extended: (es_extended/client/main.lua)

Replace this code:

Citizen.CreateThread(function()
	while true do
		Citizen.Wait(0)

		if NetworkIsPlayerActive(PlayerId()) then
			TriggerServerEvent('esx:onPlayerJoined')
			break
		end
	end
end)

with:

RegisterNetEvent('esx:kashloaded')
AddEventHandler('esx:kashloaded', function()
	TriggerServerEvent('esx:onPlayerJoined')
end)

• es_extended: (es_extended/server/main.lua)

Change this code in onPlayerJoined(playerId) function:

	for k,v in ipairs(GetPlayerIdentifiers(playerId)) do
		if string.match(v, 'license:') then
			identifier = string.sub(v, 9)
			break
		end
	end

to:

	for k,v in ipairs(GetPlayerIdentifiers(playerId)) do
		if string.match(v, 'license:') then
			identifier = v
			break
		end
	end

Read carefully...

You MUST incerase the character limit in the users table for row identifier to 48. Do not use essentialsmode, mapmanager and spawnmanager! Pay ATTENTION: You have to call the resource 'esx_kashacters' in order for the javascript to work!*

How it works

What this script does it manipulates ESX for loading characters So when you are choosing your character it changes your Rockstar license which is normally license: to Char: this prevents ESX from loading another character because it is looking for you exact license. So when you choose your character it will change it from Char: to your normal Rockstar license (license:). When creating a new character it will spawn you without an exact license which creates a new database entry for your license.
