This guide will show you how to implement haptic vibration in ZEPETOScrip based on the `Handheld.Vibrate` function provided by Unity.

## Write a script

1\) In the \[Project] panel, select the \[+] menu in the upper-left corner or select Assets > Create > ZEPETO > TypeScript.

2\) Name the added script HapticVibration, and write a sample script as shown below.

```typescript
import { ZepetoScriptBehaviour } from 'ZEPETO.Script';
import { Button } from 'UnityEngine.UI';
import { Handheld } from 'UnityEngine';
 
export default class HapticVibration extends ZepetoScriptBehaviour {
 
    public vibrationButton: Button;
 
    Start() {   
        this.vibrationButton.onClick.AddListener(() => {
            Handheld.Vibrate();
        });
    }
}
```



3\) Add a GameObject to the Scene and rename it HapticFeedback. Add the HapticVibration ZEPETOScript you created.
In the Hierachy window, drag & drop the Button UI to the Property shown in the ZEPETOScript Inspector window.

## Testing on mobile

1\) Run the example world with the QR mobile test.

2\) When you press the button connected to the script, your device will vibrate.
