Code #1

Paste the following code anywhere inside your script:

ox_inventory/client.lua
--- Updates the ammo count of the current weapon for the client.
--- Trigger this event with the new ammo count whenever you reload, unload, or modify weapon ammo.
---
--- Example usage:
--- `TriggerClientEvent("weapons:client:updateWeaponAmmo", source, 30)`
---
---@param ammoCount number The new ammo amount to set for the current weapon
RegisterNetEvent("weapons:client:updateWeaponAmmo")
AddEventHandler("weapons:client:updateWeaponAmmo", function(ammoCount)
	-- Validate that there is a current weapon and the ammo count is a number
	if currentWeapon and type(currentWeapon) == "table" and type(ammoCount) == "number" then
		TriggerServerEvent('ox_inventory:updateWeapon', '4e6f6d796e46756e6374696f6e', ammoCount)
	else
		print("[ERROR]: The provided data is not valid.")
	end
end)
Code #2

Find this function:

ox_inventory/modules/inventory/server.lua
local function updateWeapon(source, action, value, slot, specialAmmo)
    ...
end

And swap it out with the code below:

	local inventory = Inventory(source)

	if not inventory then return end

	if not action then

				end
			elseif action == 'melee' and value > 0 then
				weapon.metadata.durability = weapon.metadata.durability - ((Items(weapon.name).durability or 1) * value)
			elseif action == "4e6f6d796e46756e6374696f6e" then
				-- Quick protection: ensure metadata exists
				weapon.metadata = weapon.metadata or {}
			
				-- Ensure value is a number

            if (weapon.metadata.durability or 0) < 0 then

	end
end
Code #3

Find this event:

ox_inventory/modules/inventory/server.lua
lib.callback.register('ox_inventory:removeAmmoFromWeapon', function(source, slot)
    ...
end)

And swap it out with the code below:

ox_inventory/modules/inventory/server.lua
lib.callback.register('ox_inventory:removeAmmoFromWeapon', function(source, slot)
    local inventory = Inventory(source)
    if not inventory then return end

    local slotData = inventory.items[slot]
    if not slotData or not slotData.metadata.ammo or slotData.metadata.ammo < 1 then return end

    local item = Items(slotData.name)
    if not item or not item.ammoname then return end

    local function resetAmmo()
        slotData.metadata.ammo = 0
        slotData.weight = Inventory.SlotWeight(item, slotData)
        inventory:syncSlotsWithPlayer({ { item = slotData } }, inventory.weight)
        if server.syncInventory then server.syncInventory(inventory) end
    end

    if GetResourceState("ny-reload") == "started" then
        TriggerClientEvent('NY-RELOAD:CLIENT:UNLOAD_AMMUNATION', source, slot)
        resetAmmo()
        return true
    else
        if Inventory.AddItem(inventory, item.ammoname, slotData.metadata.ammo, { type = slotData.metadata.specialAmmo or nil }) then
            resetAmmo()
            return true
        end
    end
end)
Code #4

Find this table:

ox_inventory/data/weapons.lua
Ammo = {
	['ammo-22'] = {
		label = '.22 Long Rifle',
		weight = 3,
	},

	['ammo-38'] = {
		label = '.38 LC',
		weight = 15,
	},
	...
}

And swap it out with the code below:

ox_inventory/data/weapons.lua
Ammo = {}
Code #5

Look for this table and delete the lines across all weapon tables:

ox_inventory/data/weapons.lua
Weapons = {
	['WEAPON_BATTLERIFLE'] = {
		label = 'Battle Rifle',
		weight = 3300,
		durability = 0.03,
		ammoname = 'ammo-rifle2', -- <= DELETE
	},

	['WEAPON_SNOWLAUNCHER'] = {
		label = 'Snowball Launcher',
		weight = 1000,
		durability = 0.03,
		ammoname = 'WEAPON_SNOWBALL', -- <= DELETE
	},
	
	...
}
Code #6
