# Assembly Definitions

Unity gives the possibility to organize organize Scripts into different assemblies by using Assembly Definitions. See also the Unity Documentation:

{% embed url="<https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html>" %}

If you use external libraries within realvirtual.io which are not installed with realvirtual.io you must include these external libraries into the top assembly definition of realvirtual.io.

If you are programming your own scripts, it might be necessary to include Realvirtual.io into your own assembly definition to get access to the realvirtual.io (before 2022 game4automation) assemblies.\
Game4Automation is using the following assemblies:

| Assembly defintion name                      | Description                                       |
| -------------------------------------------- | ------------------------------------------------- |
| realvirtual.base                             | Base assembly for all realvirtual.io functions    |
| realvirtual.editor                           | realvirtual.io functions which run in editor mode |
| realvirtual.interfaces.opocua                | OPCUA interface                                   |
| realvirtual.interfaces.opocua.editor         | OPCUA editor mode                                 |
| realvirtual.interfaces.plcsimadvanded        | PLCSIM Advanced interface                         |
| realvirtual.interfaces.plcsimadvanded.editor | PLCSIM Advanced editor mode                       |
| realvirtual.interfaces.s7tcpip               | S7 TCPIP interface                                |
| realvirtual.interfaces.s7tcpip.editor        | S7 TCPIP editor                                   |
| realvirtual.interfaces.sharedmemory          | Shared Memory interface                           |
| realvirtual.interfaces.sharedmemory.editor   | Shared Memory editor                              |
| realvirtual.cadlink                          | CADlink                                           |
|                                              |                                                   |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/advanced-topics/for-developers/assembly-definitions.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.
