### Overview <a href="#overview" id="overview"></a>

The package extends the standard `Perception` workflow with additional tools for:

* target loss and reacquisition
* time-based visibility logic
* suspicion and awareness thresholds
* investigation start, completion, and failure
* last known position workflows
* target sharing between nearby agents
* temporary ignore states
* runtime tuning of vision and detection behavior

### Terminology <a href="#terminology" id="terminology"></a>

#### Tracked Target <a href="#tracked-target" id="tracked-target"></a>

Many nodes in this package operate on tracked targets. If a target-based node does not respond, first confirm that the NPC is tracking that object.

#### Awareness <a href="#awareness" id="awareness"></a>

Awareness is the value stored by `Perception` for a tracked target. In gameplay terms it is commonly used for:

* `Suspicious`
* `Alert`
* `Aware`

#### Last Known Position <a href="#last-known-position" id="last-known-position"></a>

The last known position is the most recent world position stored by `SensorSee` for a target. It is commonly used for:

* chase-to-search transitions
* search behaviors
* investigation behaviors
* movement to the last visible location

#### Investigation <a href="#investigation" id="investigation"></a>

Investigation refers to an active point of interest being checked by an NPC. In this package, that point can come from:

* an `Evidence` object
* a temporary runtime point created from a world position

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://9476764.gitbook.io/assets/gc2-perception-extensions.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.
