# Trigger Volume
There are several versions of this with different shapes of volume but they all work the same way: when the player enters the volume, the branch is triggered and plays out.
When authoring, a simple control panel will popup when you point at the trigger volume (same as for Click to Trigger).
When playing, the trigger volume will also act as a teleport target. Once triggered the volume will change colour to orange instead of cyan.

## 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.moviestorm.co.uk/firststage/interactive-scenes/triggers/trigger-volume.md?ask=&goal=
```
`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.
