Class: RigidControls

Inspired by THREE.JS's PointerLockControls, a rigid body based first person controls.

Example

// Create the controls.
const controls = new RigidControls(
  camera,
  renderer.domElement,
  world
);

// Printing the voxel that the client is in.
console.log(controls.voxel);

// Call the controls update function in the render loop.
controls.update();

Constructors

constructor

• new RigidControls(camera, domElement, world, options?): RigidControls

Construct a Voxelize rigid body based first person controls. This adds a rigid body to the world's physics engine, and applies movement to the camera.

Parameters

Name	Type	Description
camera	PerspectiveCamera	The camera to apply the controls to.
domElement	HTMLElement	The DOM element to apply the controls to.
world	World<any>	The world to apply the controls to.
options	Partial<RigidControlsOptions>	The options to initialize the controls with.

Returns

RigidControls

Overrides

EventEmitter.constructor

Properties

INPUT_IDENTIFIER

▪ Static Readonly INPUT_IDENTIFIER: "voxelize-rigid-controls"

This is the identifier that is used to bind the rigid controls' keyboard inputs when RigidControls.connect is called.

---

arm

• Optional arm: Arm

A potential link to a Arm instance. This can be added by calling RigidControls.attachArm to add a mesh for the first person view.

---

body

• body: RigidBody

The physical rigid body of the client, dimensions described by:

• options.bodyWidth
• options.bodyHeight
• options.bodyDepth

---

camera

• camera: PerspectiveCamera

Reference linking to the Voxelize camera instance.

---

character

• Optional character: Character

A potential link to a Character instance. This can be added by calling RigidControls.attachCharacter to add a mesh for 2nd and 3rd person view.

---

domElement

• domElement: HTMLElement

The DOM element that pointerlock controls are applied to.

---

inputs

• Optional inputs: Inputs<any>

Reference linking to the Voxelize Inputs instance. You can link an inputs manager by calling RigidControls.connect, which registers the keyboard inputs for the controls.

---

isLocked

• isLocked: boolean = false

Flag indicating whether pointerlock controls have control over the cursor.

---

movements

• movements: Object

Whether or not the client has certain movement potentials. For example, if the forward key is pressed, then "front" would be true. Vice versa for "back".

Type declaration

Name	Type
back	boolean
down	boolean
front	boolean
left	boolean
right	boolean
sprint	boolean
up	boolean

---

object

• object: Group<Object3DEventMap>

A THREE.JS object, parent to the camera for pointerlock controls.

---

options

• options: RigidControlsOptions

Parameters to initialize the Voxelize controls.

---

ownID

• ownID: string = ""

The client's own peer ID. This is set when the client first connects to the server.

---

state

• state: RigidControlState

The state of the control, indicating things like whether or not the client is running.

---

world

• world: World<any>

Reference linking to the Voxelize world instance.

Accessors

chunk

• get chunk(): Coords2

The chunk that the client is situated in.

Returns

Coords2

---

flyMode

• get flyMode(): boolean

Whether if the client is in fly mode. Fly mode means client can fly but not through blocks.

Returns

boolean

---

ghostMode

• get ghostMode(): boolean

Whether if the client is in ghost mode. Ghost mode means client can fly through blocks.

Returns

boolean

---

position

• get position(): Vector3

The 3D world coordinates that the client is at. This is where the bottom of the client's body is located.

Returns

Vector3

---

voxel

• get voxel(): Coords3

The voxel coordinates that the client is at. This is where the bottom of the client's body is located, floored to the voxel coordinate.

Returns

Coords3

Methods

attachArm

▸ attachArm(arm): void

Attach a Arm to this controls instance. This can be seen in 1st person mode.

Parameters

Name	Type	Description
arm	Arm	The Arm to attach to this controls instance.

Returns

void

---

attachCharacter

▸ attachCharacter(character, newLerpFactor?): void

Attach a Character to this controls instance. This can be seen in 2nd/3rd person mode.

Parameters

Name	Type	Default value	Description
character	Character	undefined	The Character to attach to this controls instance.
newLerpFactor	number	1	The new lerp factor to use for the character.

Returns

void

---

connect

▸ connect(inputs, namespace?): () => void

Sets up all event listeners for controls, including:

• Mouse move event
• Pointer-lock events
• Canvas click event
• Key up/down events
• Control lock/unlock events

This function returns a function that can be called to disconnect the controls. Keep in mind that if Inputs.remap is used to remap any controls, they will not be unbound when the returned function is called.

Parameters

Name	Type	Default value
inputs	Inputs<any>	undefined
namespace	string	"*"

Returns

fn

▸ (): void

Returns

void

Options

inputs Inputs instance to bind the controls to.

Options

namespace The namespace to bind the controls to.

---

getDirection

▸ getDirection(): Vector3

Get the direction that the client is looking at.

Returns

Vector3

---

lock

▸ lock(callback?): void

Lock the cursor to the game, calling requestPointerLock on the dom element. Needs to be called within a DOM event listener callback!

Parameters

Name	Type	Description
callback?	() => void	Callback to be run once done.

Returns
