inputPacketCreator

The InputPacketCreator class handles the conversion of user input events (keyboard and mouse) into network packets that are sent to the server. It listens to events from the InputManager and communicates with the Network module.

InputPacketCreator public

Bounded to game as game.inputPacketCreator. Alias: game.inputPacketCreatorType

Properties

Property	Type	Description
sendMouseMoveChance	number	The probability (0.0 to 1.0) of sending a mouseMoved packet to the server. Defaults to 1.
lastMouseMoveYaw	number	The last yaw angle sent during a mouse move event. Used for deduplication.
lastMouseDragYaw	number	The last yaw angle sent during a mouse drag event. Used for deduplication.
lastAnyYaw	number	The most recent yaw angle recorded from any mouse interaction.
enabled	boolean	Whether the packet creator is currently processing and sending inputs.

Methods

start()

function start(): void

Initializes the packet creator by binding to key and mouse events from InputManager.

setSendMouseMoveChance()

function setSendMouseMoveChance(chance: number): void

Sets the probability of sending mouse move packets.

getLastAnyYaw()

function getLastAnyYaw(): number

Returns the most recent yaw angle recorded.

getEnabled()

function getEnabled(): boolean

Returns whether the input packet creator is currently enabled.

setEnabled()

function setEnabled(enabled: boolean): void

Sets the enabled state of the packet creator.

bindKeys()

function bindKeys(): void

Binds listeners to keyPress and keyRelease events. It maps WASD and arrow keys to directional input packets (up, down, left, right) and the spacebar to the space input. Input is ignored if an input or textarea element is active.

bindMouse()

function bindMouse(): void

Binds listeners to mouse events (mouseDown, mouseUp, mouseMovedWhileDown, mouseMoved). It calculates the yaw angle and sends corresponding input packets to the server.

screenToYaw()

function screenToYaw(x: number, y: number): number

Calculates the angle (in degrees, 0-359) from the center of the screen to the specified (x, y) coordinates.

screenToWorld()

function screenToWorld(event: MouseEvent): object

Converts screen coordinates to world coordinates { x, y }, rounding values down to the nearest integer.

distanceToCenter()

function distanceToCenter(x: number, y: number): number

Calculates the distance from the screen center to the specified (x, y) coordinates.

Input Data

The following fields are sent to InputPacketSchduler via scheduler.scheduleInput(). Each packet contains one or more of these properties representing the player's current input state.

Movement & Actions

Field	Type	Keys	Description
up	number	W, Up Arrow	1 to move up, 0 to stop.
down	number	S, Down Arrow	1 to move down, 0 to stop.
left	number	A, Left Arrow	1 to move left, 0 to stop.
right	number	D, Right Arrow	1 to move right, 0 to stop.
space	number	Space	1 when the spacebar is pressed, 0 when released.

Mouse Interaction

Field	Type	Description
mouseDown	number	Sent when the left mouse button is pressed. Contains the current yaw angle. Must also includes worldX, worldY, and distance in other fields.
mouseUp	number	Sent as 1 when the left mouse button is released. Must also includes worldX, worldY, and distance in other fields.
mouseMoved	number	Sent when the mouse moves (subject to sendMouseMoveChance). Contains the current yaw angle. Must also includes worldX, worldY, and distance in other fields.
mouseMovedWhileDown	number	Sent when the mouse moves while the left button is held. Contains the current yaw angle. Must also includes worldX, worldY, and distance in other fields.
worldX	number	The X-coordinate of the mouse in the world.
worldY	number	The Y-coordinate of the mouse in the world.
distance	number	The distance from the mouse to the center of the screen.

INFO

The yaw angle is rounded and normalized to a 0-359 range before being sent to the server.
