# Custom Events

### Description

OVER SDK Visual Scripting also provides the User a tool to define and use Custom events.

These events need to be defined inside a Graph and are only usable inside such.

#### Custom Event Node

Each Custom Event Node must be defined by a (unique) Name. In order to fire this event use a Custom Event Trigger

#### Custom Event Trigger

In order to fire a defined Custom Event, a Custom Event Trigger needs to be inserted in another execution flow of the Graph.&#x20;

By editing its Name parameter, it is possible to fire the execution of the Custom Event Node with the corresponding name.

## 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.overthereality.ai/over-sdk-manual/over-visual-scripting-legacy/nodes/flow/other-events/custom-events.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.
