Phaser Class: DisplayObjectContainer

new DisplayObjectContainer()

A DisplayObjectContainer represents a collection of display objects. It is the base class of all display objects that act as a container for other objects.

Extends

PIXI.DisplayObject

Members

alpha :Number

The opacity of the object.

Inherited From:

PIXI.DisplayObject#alpha

Source - pixi/display/DisplayObject.js, line 65

buttonMode :Boolean

This is used to indicate if the displayObject should display a mouse hand cursor on rollover

Inherited From:

PIXI.DisplayObject#buttonMode

Source - pixi/display/DisplayObject.js, line 90

cacheAsBitmap :Boolean

Set if this display object is cached as a bitmap. This basically takes a snap shot of the display object as it is at that moment. It can provide a performance benefit for complex static displayObjects. To remove simply set this property to 'null'

Inherited From:

PIXI.DisplayObject#cacheAsBitmap

Source - pixi/display/DisplayObject.js, line 436

<readonly> children :Array.<DisplayObject>

[read-only] The array of children of this container.

Type:

Array.<DisplayObject>

Source - pixi/display/DisplayObjectContainer.js, line 17

defaultCursor :String

This is the cursor that will be used when the mouse is over this object. To enable this the element must have interaction = true and buttonMode = true

Inherited From:

PIXI.DisplayObject#defaultCursor

Source - pixi/display/DisplayObject.js, line 143

filterArea :PIXI.Rectangle

The area the filter is applied to like the hitArea this is used as more of an optimisation rather than figuring out the dimensions of the displayObject each frame you can set this rectangle

Inherited From:

PIXI.DisplayObject#filterArea

Source - pixi/display/DisplayObject.js, line 180

filters :Array.<Filter>

Sets the filters for the displayObject. IMPORTANT: This is a webGL only feature and will be ignored by the canvas renderer. To remove filters simply set this property to 'null'

Type:

Array.<Filter>

Inherited From:

PIXI.DisplayObject#filters

Source - pixi/display/DisplayObject.js, line 400

height :Number

The height of the displayObjectContainer, setting this will actually modify the scale to achieve the value set

Source - pixi/display/DisplayObjectContainer.js, line 63

hitArea :PIXI.Rectangle|PIXI.Circle|PIXI.Ellipse|PIXI.Polygon

This is the defined area that will pick up mouse / touch events. It is null by default. Setting it is a neat way of optimising the hitTest function that the interactionManager will use (as it will not need to hit test all the children)

Type:

PIXI.Rectangle | PIXI.Circle | PIXI.Ellipse | PIXI.Polygon

Inherited From:

PIXI.DisplayObject#hitArea

Source - pixi/display/DisplayObject.js, line 81

interactive :Boolean

Indicates if the sprite will have touch and mouse interactivity. It is false by default

Inherited From:

PIXI.DisplayObject#interactive

Default Value:

false

Source - pixi/display/DisplayObject.js, line 339

mask :PIXI.Graphics

Sets a mask for the displayObject. A mask is an object that limits the visibility of an object to the shape of the mask applied to it. In PIXI a regular mask must be a PIXI.Graphics object. This allows for much faster masking in canvas as it utilises shape clipping. To remove a mask, set this property to null.

Inherited From:

PIXI.DisplayObject#mask

Source - pixi/display/DisplayObject.js, line 380

<readonly> parent :PIXI.DisplayObjectContainer

[read-only] The display object container that contains this display object.

Inherited From:

PIXI.DisplayObject#pivot

Source - pixi/display/DisplayObject.js, line 49

position :PIXI.Point

Inherited From:

PIXI.DisplayObject#position

Source - pixi/display/DisplayObject.js, line 14

renderable :Boolean

Inherited From:

PIXI.DisplayObject#renderable

scale :PIXI.Point

The scale factor of the object.

Inherited From:

PIXI.DisplayObject#scale

Source - pixi/display/DisplayObject.js, line 22

<readonly> stage :PIXI.Stage

[read-only] The stage the display object is connected to, or undefined if it is not connected to the stage.

Inherited From:

PIXI.DisplayObject#stage

Source - pixi/display/DisplayObject.js, line 115

transformCallback :function

The transform callback is an optional callback that if set will be called at the end of the updateTransform method and sent two parameters: This Display Objects worldTransform matrix and its parents transform matrix. Both are PIXI.Matrix object types. The matrix are passed by reference and can be modified directly without needing to return them. This ability allows you to check any of the matrix values and perform actions such as clamping scale or limiting rotation, regardless of the parent transforms.

Inherited From:

PIXI.DisplayObject#transformCallback

Inherited From:

PIXI.DisplayObject#worldAlpha
