Class: InteractionManager

PIXI.interaction.InteractionManager

The interaction manager deals with mouse, touch and pointer events. Any DisplayObject can be interactive if its interactive parameter is set to true This manager also supports multitouch.

An instance of this class is automatically created by default, and can be found at renderer.plugins.interaction

new PIXI.interaction.InteractionManager (renderer, options)

Name Type Description
renderer PIXI.CanvasRenderer | PIXI.WebGLRenderer

A reference to the current renderer

options object optional

The options for the manager.

Name Type Default Description
autoPreventDefault boolean true optional

Should the manager automatically prevent default browser actions.

interactionFrequency number 10 optional

Frequency increases the interaction events will be checked.

Extends

  • EventEmitter

Members

autoPreventDefault boolean

Should default browser actions automatically be prevented. Does not apply to pointer events for backwards compatibility preventDefault on pointer events stops mouse events from firing Thus, for every pointer event, there will always be either a mouse of touch event alongside it.

Default Value:
  • true

currentCursorMode string

The mode of the cursor that is being used. The value of this is a key from the cursorStyles dictionary.

currentCursorStyle string Deprecated : since 4.3.0

See:

cursorStyles Object.<string, (string|function()|Object.<string, string>)>

Dictionary of how different cursor modes are handled. Strings are handled as CSS cursor values, objects are handled as dictionaries of CSS values for interactionDOMElement, and functions are called instead of changing the CSS. Default CSS cursor values are provided for 'default' and 'pointer' modes.

defaultCursorStyle string Deprecated : since 4.3.0

See:

eventData object

An event data object to handle all the event tracking/dispatching

interactionFrequency number

Frequency in milliseconds that the mousemove, moveover & mouseout interaction events will be checked.

Default Value:
  • 10

The mouse data

moveWhenInside boolean

This property determines if mousemove and touchmove events are fired only when the cursor is over the object. Setting to true will make things work more in line with how the DOM verison works. Setting to false can make things easier for things like dragging It is currently set to false as this is how PixiJS used to work. This will be set to true in future versions of pixi.

Default Value:
  • false

The renderer this interaction manager works for.

resolution number

The current resolution / device pixel ratio.

Default Value:
  • 1

supportsPointerEvents boolean readonly

Does the device support pointer events https://www.w3.org/Submission/pointer-events/

supportsTouchEvents boolean readonly

Does the device support touch events https://www.w3.org/TR/touch-events/

Methods

Destroys the interaction manager

hitTest (globalPoint, root)PIXI.DisplayObject

Hit tests a point against the display tree, returning the first interactive object that is hit.

Name Type Description
globalPoint PIXI.Point

A point to hit test with, in global space.

root PIXI.Container optional

The root display object to start from. If omitted, defaults to the last rendered root of the associated renderer.

Returns:
Type Description
PIXI.DisplayObject The hit display object, if any.

mapPositionToPoint (point, x, y)

Maps x and y coords from a DOM object and maps them correctly to the PixiJS view. The resulting value is stored in the point. This takes into account the fact that the DOM element could be scaled and positioned anywhere on the screen.

Name Type Description
point PIXI.Point

the point that the result will be stored in

x number

the x coord of the position to map

y number

the y coord of the position to map

setCursorMode (mode)

Sets the current cursor mode, handling any callbacks or CSS style changes.

Name Type Description
mode string

cursor mode, a key from the cursorStyles dictionary

setTargetElement (element, resolution)

Sets the DOM element which will receive mouse/touch events. This is useful for when you have other DOM elements on top of the renderers Canvas element. With this you'll be bale to deletegate another DOM element to receive those events.

Name Type Default Description
element HTMLCanvasElement

the DOM element which will receive mouse and touch events.

resolution number 1 optional

The resolution / device pixel ratio of the new element (relative to the canvas).

update (deltaTime)

Updates the state of interactive objects. Invoked by a throttled ticker update from PIXI.ticker.shared.

Name Type Description
deltaTime number

time delta since last tick
