# Loot Object Receiver

This type of component is responsible for information when hovering over the selected object.

![](/files/-MdbEkU1rU1x6rlFq9LA)

Each selected item has its own Canvas, which requires additional configuration.

![](/files/-MdbFr2zn424aP9ICIv7)

And so let's take a look at all the components we need in order:

## UI Billboard Effect 

He is responsible for ensuring that the canvas always looks at the player.

### Automatically

We can set the target via the object tag.

![](/files/-MdbGELu7WmEGV0VLxbo)

{% hint style="success" %}
**Example:**

If we work in **Prefab**, then we can't manually specify the camera and then this method will help us, when initializing an object, the system will find an object with the necessary tag itself and the canvas will always look at it.
{% endhint %}

### Manual

We can pass the target that the Canvas will look at manually.

## Rect Transform Placer

![](/files/-MdbHnE299kMPOPadVD8)

Responsible for the position of the canvas relative to the object.

{% hint style="success" %}
**Example:**

When we throw an object, the canvas is still static relative to the object, and does not rotate with it.
{% endhint %}
