ESX Imports

Similar to importing the ESX locale functions or MySQL-Async, there is now an import for ESX

• Define shared_script '@es_extended/imports.lua' above all other scripts in your fxmanifest
• This will define the ESX object for both the client and server

The following event handler will also be created on the client

	AddEventHandler('esx:setPlayerData', function(key, val)
		if GetInvokingResource() == 'es_extended' then
			ESX.PlayerData[key] = val
			if OnPlayerData ~= nil then OnPlayerData(key, val) end
		end
	end)

• You will now receive updated ESX.PlayerData values whenever they change
  • This does not include inventory or loadout data and it should still be retrieved with ESX.GetPlayerData()
  • You can add your own functions to the import if you believe they will be useful in your resources
  • You can trigger certain events or functions based on the key and value received (example in client.lua)
  • The idea of this function is ensuring up-to-date values for job, accounts, ped, and dead
  • You can set any data this way if you want to share it between resources
    • Using ESX.SetPlayerData('cuffed', true) will create and set a new value that you can now reference anywhere
    • If you are using OneSync you could set certain values to set a state bag (useful for other players to reference)

Replacement for ESX.GetPlayers()

Old resources would utilise the ESX.GetPlayers() function in a loop with ESX.GetPlayerFromId() to retrieve xPlayer data

• This can be referred to as an xPlayer loop, and has been the cause for server hitches in resources such as esx_society and esx_status
• It is commonly used in robbery scripts to get the active number of cops, or for determining the number of EMS in other places

This method is outdated and should be replaced if you are using ESX Legacy

	local xPlayers = ESX.GetPlayers()
	for i=1, #xPlayers, 1 do
		local xPlayer = ESX.GetPlayerFromId(xPlayers[i])
		if xPlayer.job.name == 'police' then
			TriggerClientEvent('esx:showNotification', xPlayers[i], 'You are a cop!')
		end
	end

This new method retrieves all xPlayer data at once, reducing the number of function references being called

	local xPlayers = ESX.GetExtendedPlayers() -- Returns all xPlayers
 	for _, xPlayer in pairs(xPlayers) do
		if xPlayer.job.name == 'police' then
			TriggerClientEvent('esx:showNotification', xPlayer.source, 'You are a cop!')
		end
	end

	local xPlayers = ESX.GetExtendedPlayers('job', 'police') -- Returns xPlayers with the police job
 	for _, xPlayer in pairs(xPlayers) do
		TriggerClientEvent('esx:showNotification', xPlayer.source, 'You are a cop!')
	end
