This script replaces the weapon loadout system in FiveM and ESX. Instead of handling the loadout as its own thing, all weapons are stored as items in the player's inventory. Ammo is also stored as items.

Before using this, you should modify ESX to allow "silent" removal of inventory items, or the players will be spammed when they are shooting. In my version of ESX, I modified the following in es_extended/client/main.lua:

RegisterNetEvent('esx:removeInventoryItem')
AddEventHandler('esx:removeInventoryItem', function(item, count, silent)

  for i=1, #ESX.PlayerData.inventory, 1 do
    if ESX.PlayerData.inventory[i].name == item.name then
      ESX.PlayerData.inventory[i] = item
    end
  end

  if not silent then
    ESX.UI.ShowInventoryItemNotification(false, item, count)
  end

  if ESX.UI.Menu.IsOpen('default', 'es_extended', 'inventory') then
    ESX.ShowInventory()
  end

end)

Secondly, you must add all weapons you would like to use in your item database. See the attached items.sql for an example.

Lastly, you must modify ESX and all other resources that handles the weapon loadout to use items instead. Otherwise things will f up.
