esx_inventoryhud

This one is kinda harder because it needs larger edit.

Create in esx_inventoryhud/client file called rcore_hotel.lua You will need to add this file to the fxmanifest.lua / __resource.lua

and use this copy and paste this following code

STORAGE_SECTION_ITEMS = 'items'
STORAGE_SECTION_WEAPONS = 'weapons'
STORAGE_SECTION_ACCOUNTS = 'accounts'
STORAGE_ACCOUNTS_BLACK = 'blackMoney'
STORAGE_ACCOUNTS_CASH = 'cash'

local lastData = {}

RegisterNetEvent("esx_inventoryhud:openRcoreHotelInventory")
AddEventHandler("esx_inventoryhud:openRcoreHotelInventory", function(data)
    setRcoreHotelInventoryData(data)
    openRcoreHotelInventory()
end)

function refreshHotelInventory()
    if lastData ~= nil then
        exports.rcore_hotel:callCallback("rcore_hotel:getStorage",
                function(inventory)
                    local exportFormat = {
                        ['blackMoney'] = inventory['accounts']['blackMoney'] or 0,
                        ['money'] = inventory['accounts']['cash'] or 0,
                        ['items'] = inventory['items'],
                        ['weapons'] = inventory['weapons'],
                        ['hotel'] = lastData.hotel,
                        ['room'] = lastData.room,
                    }

                    setRcoreHotelInventoryData(exportFormat)
                end, lastData.hotel, lastData.room)
    end

We need to edit esx_inventoryhud/html/inventory.js as well, and because it is a bit harder than ctrl c + v I will put the whole file there so you can just grab it.

After we're done with this, we will hop to the config.lua and change this value to true

Config.InventorySystem = "4"
