# Server

#### `useLudusBoard` (ox\_inventory)

Primary entry for **ox\_inventory** usable items.

**Item setup:**

```lua
['ludus_board'] = {
    label = 'Ludus Board',
    weight = 500,
    stack = true,
    close = true,
    consume = 0,
    description = 'Use to place a Ludus table.',
    server = {
        export = 'cdev_ludus.useLudusBoard'
    }
},
```

```lua
exports('useLudusBoard', function(event, item, inventory, slot, data)
    -- ox_inventory usable-item callback
    -- Triggers client placement when event == 'usingItem'
end)
```

{% hint style="danger" %}
Always keep **`consume = 0`**. The resource removes the item when placement starts and returns it on cancel.
{% endhint %}
