# Logic in Prefabs

**Prefabs** contain their own **Logic** and it applies to all instances of the **Prefab**. The **Prefab** **Logic** can be incorporated into the **Scene Logic** via a **Prefab Node**, which can be found in the **Logic Editor** by choosing the **Prefab** tab on the left Menu.

To open the **Prefab Logic** graph in the **Logic Editor** either double-click the **Prefab Node** in the **Logic Editor** or the **Prefab Asset** in the **Asset Manager**.

The **Prefab Logic** has two **Nodes** by default: **Prefab Input** and **Prefab Output**. These represent the **Input** and **Output** of the **Prefab Node**, respectively.

These two **Nodes** can have their **Attributes** customized: **Input Sockets** can be added to the **Prefab Input** **Node** and **Output Sockets** to the **Prefab Output** **Node**. These changes will then be reflected in the **Prefab Node**.

## 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://docs.incari.com/incari-studio/2022.2/objects-and-types/prefabs/logic-prefabs.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.
