# HMI Slider (Deprecated)

{% hint style="danger" %}
**Deprecated — no realvirtual WEB equivalent.** This interactive Unity uGUI control is deprecated. It is **not exported to realvirtual WEB** and has no direct counterpart there — the browser-based 3D-HMI does not use authored slider / switch / button / dropdown widgets. Instead, [**realvirtual WEB**](/extensions/realvirtual-web.md) builds operator HMIs from its own components and plugin system (WebSensor, WebError, KPI and message panels, and the React overlay layer). Writing signals from the browser is handled by the connect/debug tools, not by authored control widgets.
{% endhint %}

The HMI Value slider can set PLCInputFloat or PLCInputInt values on the connected PLC..

The Value is always displayed. The slider appears as soon as the user is hovering over the object with the mouse. To use it with the render mode "Worldspace" you need the HMI-PanelWorldSpace as parent.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.realvirtual.io/components-and-scripts/scene-interaction/hmi-components-pro/hmi-slider.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
