# Item Visibility

a.k.a the basics of the Hider component

To make an item that can only be collected once, let’s create another link.

Click on the collectible and add the ‘**Hider**’ component, and then go to Linking. 

Add another link by pressing + and select **‘Interacted**,’ then link back **onto the object itself** by clicking a little box that will appear just above the + on the top right corner. Select ‘**Hide**’ — now, when you interact to collect the item, it will disappear.

{% hint style="info" %}
Objects that have 'disappeared' will still have collision on them - meaning, you can still run into them and they will act as an invisible wall. To avoid this, you'll need to also assign the entity the **Collision Toggler** component, and create some more links.

Learn how to do that here.
