Class: InputManager

Phaser.Input. InputManager

The Input Manager is responsible for handling the pointer related systems in a single Phaser Game instance.

Based on the Game Config it will create handlers for mouse and touch support.

Keyboard and Gamepad are plugins, handled directly by the InputPlugin class.

It then manages the events, pointer creation and general hit test related operations.

You rarely need to interact with the Input Manager directly, and as such, all of its properties and methods should be considered private. Instead, you should use the Input Plugin, which is a Scene level system, responsible for dealing with all input events for a Scene.

new InputManager(game, config)

Parameters:
Name Type Description
game Phaser.Game

The Game instance that owns the Input Manager.
config object

The Input Configuration object, as set in the Game Config.
Since: 3.0.0
Source: src/input/InputManager.js (Line 19)

Members

activePointer :Phaser.Input.Pointer

The most recently active Pointer object.

If you've only 1 Pointer in your game then this will accurately be either the first finger touched, or the mouse.

If your game doesn't need to support multi-touch then you can safely use this property in all of your game code and it will adapt to be either the mouse or the touch, based on device.

globalTopOnly :boolean

If the top-most Scene in the Scene List receives an input it will stop input from propagating any lower down the scene list, i.e. if you have a UI Scene at the top and click something on it, that click will not then be passed down to any other Scene below.

Methods

addPointer( [quantity])

Adds new Pointer objects to the Input Manager.

By default Phaser creates 2 pointer objects: mousePointer and pointer1.

You can create more either by calling this method, or by setting the input.activePointers property in the Game Config, up to a maximum of 10 pointers.

The first 10 pointers are available via the InputPlugin.pointerX properties, once they have been added via this method.

Parameters:
Name Type Argument Default Description
quantity number <optional>
 1

The number of new Pointers to create. A maximum of 10 is allowed in total.
Since: 3.10.0
Source: src/input/InputManager.js (Line 467)
Returns:

An array containing all of the new Pointer objects that were created.

Type
Array.<Phaser.Input.Pointer>

<protected> boot()

The Boot handler is called by Phaser.Game when it first starts up. The renderer is available by now.

Since: 3.0.0
Source: src/input/InputManager.js (Line 307)
Fires:

destroy()

Destroys the Input Manager and all of its systems.

There is no way to recover from doing this.

Since: 3.0.0
Source: src/input/InputManager.js (Line 1043)

hitTest(pointer, gameObjects, camera [, output])

Performs a hit test using the given Pointer and camera, against an array of interactive Game Objects.

The Game Objects are culled against the camera, and then the coordinates are translated into the local camera space and used to determine if they fall within the remaining Game Objects hit areas or not.

If nothing is matched an empty array is returned.

This method is called automatically by InputPlugin.hitTestPointer and doesn't usually need to be invoked directly.

Parameters:
Name Type Argument Description
pointer Phaser.Input.Pointer

The Pointer to test against.
gameObjects array

An array of interactive Game Objects to check.
camera Phaser.Cameras.Scene2D.Camera

The Camera which is being tested against.
output array <optional>

An array to store the results in. If not given, a new empty array is created.
Since: 3.0.0
Source: src/input/InputManager.js (Line 854)
Returns:

An array of the Game Objects that were hit during this hit test.

Type
array

pointWithinHitArea(gameObject, x, y)

Checks if the given x and y coordinate are within the hit area of the Game Object.

This method assumes that the coordinate values have already been translated into the space of the Game Object.

If the coordinates are within the hit area they are set into the Game Objects Input localX and localY properties.

Parameters:
Name Type Description
gameObject Phaser.GameObjects.GameObject

The interactive Game Object to check against.
x number

The translated x coordinate for the hit test.
y number

The translated y coordinate for the hit test.
Since: 3.0.0
Source: src/input/InputManager.js (Line 933)
Returns:

true if the coordinates were inside the Game Objects hit area, otherwise false.

Type
boolean

pointWithinInteractiveObject(object, x, y)

Checks if the given x and y coordinate are within the hit area of the Interactive Object.

This method assumes that the coordinate values have already been translated into the space of the Interactive Object.

If the coordinates are within the hit area they are set into the Interactive Objects Input localX and localY properties.

Parameters:
Name Type Description
object Phaser.Types.Input.InteractiveObject

The Interactive Object to check against.
x number

The translated x coordinate for the hit test.
y number

The translated y coordinate for the hit test.
Since: 3.0.0
Source: src/input/InputManager.js (Line 970)
Returns:

true if the coordinates were inside the Game Objects hit area, otherwise false.

Type
boolean

setDefaultCursor(cursor)

Tells the Input system to set a custom cursor.

This cursor will be the default cursor used when interacting with the game canvas.

If an Interactive Object also sets a custom cursor, this is the cursor that is reset after its use.

Any valid CSS cursor value is allowed, including paths to image files, i.e.:

this.input.setDefaultCursor('url(assets/cursors/sword.cur), pointer');

Please read about the differences between browsers when it comes to the file formats and sizes they support:

https://developer.mozilla.org/en-US/docs/Web/CSS/cursor https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_User_Interface/Using_URL_values_for_the_cursor_property

It's up to you to pick a suitable cursor format that works across the range of browsers you need to support.

Parameters:
Name Type Description
cursor string

The CSS to be used when setting the default cursor.
Since: 3.10.0
Source: src/input/InputManager.js (Line 392)

transformPointer(pointer, pageX, pageY, wasMove)

Transforms the pageX and pageY values of a Pointer into the scaled coordinate space of the Input Manager.

Parameters:
Name Type Description
pointer Phaser.Input.Pointer

The Pointer to transform the values for.

pointers Array.<Phaser.Input.Pointer>

An array of Pointers on which the event occurred.
Since: 3.16.0
