# Applying attributes on all network related methods.

Whenever someone add a script implementing NetworkBehaviour, they have access to the following attributes, indicating if a given method should be server only, client only, or both :

* \[Server] for server only code.
* \[Client] for client only code.
* \[ServerOrClient] for both.

Make sure no methods goes without an attribute in a script inheriting NetworkBehaviour. The goal is to increase readability and to generate warnings or exceptions when clients or server are attempting to call something they should not.

Methods with \[ServerOrClient] attributes should stay uncommon, they make debugging harder. If possible, try to refactor the code to avoid them.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://ss3d.gitbook.io/dev-guide/guidelines/the-c-style-guide/declarations/common-patterns-and-structure/applying-attributes-on-all-network-related-methods..md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
