Custom inventories and frameworks

In our scripts that are made for certain frameworks like ESX or QB we have included bridge.lua file in server/main.lua.
Here you can easily integrate your custom inventory or custom framework into our scripts.

The file looks like this:

--server/bridge.lua
function Setup()
    local bridgeDetected = false

    if(GetResourceState("ox_inventory") ~= "missing") then

            return exports['ox_inventory']:AddItem(source, itemName, count)
        end
        Bridge.RemoveItem = function(source, itemName, count)
            return exports['ox_inventory']:RemoveItem(source, itemName, count)
        end
        Bridge.GetItemCount = function(source, itemName)
