# TargetKeys

`TargetKeys` play a pivotal role in the GOAP system by specifying positions or locations within the game environment. These keys help the `Planner` calculate the distance (and added cost) between `Actions` and the precise location an `Agent` needs to reach before executing a particular action.

Each `TargetKey` is associated with a `TargetSensor`. This sensor is responsible for determining and providing the exact position corresponding to the `TargetKey`. In essence, while the `TargetKey` acts as a label or identifier for a location, the `TargetSensor` ensures that this label is mapped to a valid and up-to-date position in the game world.

## Creating a TargetKey

### Using ScriptableObject:

1. In the Unity editor, right-click on a desired folder.
2. Navigate to `Create > Goap > TargetKey` to generate a new `TargetKey`.

### Using Code:

To programmatically create a new `TargetKey`, you'll need to define a new class that inherits from the `TargetKeyBase` class.

#### Example:

{% code title="WanderTarget.cs" lineNumbers="true" %}

```csharp
using CrashKonijn.Goap.Behaviours;

public class WanderTarget : TargetKeyBase
{
}
```

{% endcode %}

## 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://goap.crashkonijn.com/goap-v2/classes/targetkeys.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.
