# Basic

The Basic Example illustrates how to manage UI objects from the Player object using locally instantiated `PlayerUI` prefabs with [SyncVars](/docs/manual/guides/synchronization/syncvars.md) and Events

<div align="left"><img src="/files/5bTfCgn7M2MkFhjHr2xr" alt=""></div>

The scene Canvas has a `CanvasUI` script with references to its children:

<div align="left"><img src="/files/JsxBfSOFJ987JGPi4Uza" alt="Scene Canvas"></div>

The `PlayerUI` prefab is a UI fragment that has a `PlayerUI` script with references to its own children:

<div align="left"><img src="/files/vZ0xSXPRCr8zyhwZYHbc" alt="PlayerUI Prefab"></div>

The Player script on the Player object has a reference to the `PlayerUI` prefab and three `SyncVars`:

<div align="left"><img src="/files/OCxsdg9APSbcMzoRsfON" alt="Player Object"></div>

The Player script also has three events that are invoked by the [SyncVar hooks](/docs/manual/guides/synchronization/syncvar-hooks.md):

```
public event System.Action<int> OnPlayerNumberChanged;
public event System.Action<Color32> OnPlayerColorChanged;
public event System.Action<int> OnPlayerDataChanged;
```

When the Player object is spawned on the client, a `PlayerUI` is instantiated as a child of the `PlayersPanel` in the Canvas via the references provided in the `CanvasUI` script, and the `SetPlayer` method is called with the corresponding Player script reference.  The `PlayerUI` script subscribes to the events above, and updates its UI elements as the `SyncVars` are updated from the server.
