# Custom Script

For very advanced mission logic, you can add a custom script to your mission. A custom script refers to an [MSFS Mission script](https://docs.flightsimulator.com/html/Content_Configuration/Flights_And_Missions/Mission_Definitions.htm), coded in .xml and compiled to .spb.

You can place the mission script on a certain location in the world. It will be available in the whole world, but objects placed at 0,0 in the mission script will be moved to the specified location.

To add a script file to the simulator, you can use a [Mission Package](/miltech-mission-hub/developer-sdk/mission-package.md).

### Actions

**Custom Script** doesn't have any actions or events, but you can use [Custom Code](/miltech-mission-hub/developer-sdk/advanced-map-objects/custom-code.md) to communicate using Lvars.

# 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://docs.miltechsimulations.com/miltech-mission-hub/developer-sdk/advanced-map-objects/custom-script.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.
