RegisterServerEvent('esx:giveInventoryItem')
AddEventHandler('esx:giveInventoryItem', function(target, type, itemName, itemCount)
	local _source = source

	local sourceXPlayer = ESX.GetPlayerFromId(_source)
	local targetXPlayer = ESX.GetPlayerFromId(target)

	if type == 'item_standard' then

		local sourceItem = sourceXPlayer.getInventoryItem(itemName)
		local targetItem = targetXPlayer.getInventoryItem(itemName)

		if itemCount > 0 and sourceItem.count >= itemCount then

			if targetItem.limit ~= -1 and (targetItem.count + itemCount) > targetItem.limit then
				TriggerClientEvent('esx:showNotification', _source, _U('ex_inv_lim', targetXPlayer.name))
			else
				sourceXPlayer.removeInventoryItem(itemName, itemCount)
				targetXPlayer.addInventoryItem   (itemName, itemCount)
				
				TriggerClientEvent('esx:showNotification', _source, _U('gave_item', itemCount, ESX.Items[itemName].label, targetXPlayer.name))
				TriggerClientEvent('esx:showNotification', target,  _U('received_item', itemCount, ESX.Items[itemName].label, sourceXPlayer.name))
			end

		else
			TriggerClientEvent('esx:showNotification', _source, _U('imp_invalid_quantity'))
