# PartArrows

class `cee.mrk.``PartArrows`()

  A part that can show arrows in a `MarkupModel`.

  Use `MarkupModel.addArrowsPart` to create a new instance of this class.

Accessors

- `color`
- `customData`

Methods

- `addArrow`
- `rayIntersect`
- `removeAllArrows`
- `setArrows`
- `setArrowsFloat32Array`

## Accessors

`PartArrows.``color`()

  The single color of all arrows

  Return type: | Color3Like

`PartArrows.``color`(color)

  Arguments: | color (`Color3Like`) – None
  Return type: | void

`PartArrows.``customData`()

  Custom data for the part. This field is not used by EnvisionWeb.

  Return type: | any

`PartArrows.``customData`(data)

  Arguments: | data (`any`) – None
  Return type: | void

## Methods

### addArrow

`PartArrows.``addArrow`(position, direction)

  Arguments: | position (`Vec3Like`) – None direction (`Vec3Like`) – None

  Add an arrow with position and direction to the part

  Return type: | void

### rayIntersect

`PartArrows.``rayIntersect`(_ray, _hitItem)

  Arguments: | _ray (`Ray`) – None _hitItem (`PartHitItem`) – None

  Not implemented, always returns false

  Return type: | boolean

### removeAllArrows

`PartArrows.``removeAllArrows`()

  Remove all arrows from the part

  Return type: | void

### setArrows

`PartArrows.``setArrows`(vertexArray, vectorArray)

  Arguments: | vertexArray (`ArrayLike`) – None vectorArray (`ArrayLike`) – None

  Sets the arrows by providing the vertices (start points) and the vectors (direction and length)

  The coordinates and vectors need to be interleaved (x0, y0, z0, x1, y1, z1, …)

  Return type: | void

### setArrowsFloat32Array

`PartArrows.``setArrowsFloat32Array`(vertexArray, vectorArray)

  Arguments: | vertexArray (`Float32Array`) – None vectorArray (`Float32Array`) – None

  Sets the arrows by providing the vertices (start points) and the vectors (direction and length)

  The coordinates and vectors need to be interleaved (x0, y0, z0, x1, y1, z1, …)

  This is the most optimal setting as the PartArrows will just hold a reference to the passed array and not copy any data.

  Return type: | void
