# Grabbable Highlighter

## Hand Grabbable Highlighter

The `HandGrabbableHighlighter` class manages the highlighting of grabbable objects within reach of a hand in Unity. It periodically updates the highlighted object based on the hand's position and orientation.

### Public Variables

* `Palm Forward Right Direction` : When choosing between multiple targets to highlight, the hand will favor objects in the palm's local forward direction (0) or the palm's local right direction (1), or a blend between the two (recommended 0.5-0.75).

### Public Methods

#### GetHighlightHit

```csharp
csharpCopy codepublic RaycastHit GetHighlightHit()
```

Returns the closest raycast hit from the hand's highlighting system. If no highlight is present, returns a blank raycasthit.

**Returns:**

* `RaycastHit`: The closest raycast hit.

#### HandClosestHit

```csharp
csharpCopy codepublic virtual Vector3 HandClosestHit(out RaycastHit closestHit, out IGrabbableEvents grabbable, float dist, int layerMask, Grabbable target = null)
```

Finds the closest raycast hit from a cone of rays and returns the average direction of all hits.

**Parameters:**

* `closestHit`: Outputs the closest raycast hit.
* `grabbable`: Outputs the closest grabbable object.
* `dist`: The distance to check for hits.
* `layerMask`: The layer mask to use for raycasting.
* `target`: An optional target grabbable object to check for.

**Returns:**

* `Vector3`: The average direction of all hits.
