Constructor

PIXI. 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.

Source code: pixi/display/DisplayObjectContainer.js (Line 5)

Extends

Public Properties

alpha : number

The opacity of the object.

Inherited From
Source code: pixi/display/DisplayObject.js (Line 46)

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
Source code: pixi/display/DisplayObject.js (Line 355)

[readonly] children : Array.<DisplayObject>

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

Type
Source code: pixi/display/DisplayObjectContainer.js (Line 17)

filterArea :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
Source code: pixi/display/DisplayObject.js (Line 164)

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'.

You cannot have a filter and a multiply blend mode active at the same time. Setting a filter will reset this objects blend mode to NORMAL.

Type
  • Array.<Filter>
Inherited From
Source code: pixi/display/DisplayObject.js (Line 307)

height : number

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

Source code: pixi/display/DisplayObjectContainer.js (Line 61)

hitArea :Rectangle | Circle | Ellipse | 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
  • Rectangle | Circle | Ellipse | Polygon
Inherited From
Source code: pixi/display/DisplayObject.js (Line 62)

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.

visible : boolean

The visibility of the object.

[read-only] The multiplied alpha of the displayObject

Inherited From
Source code: pixi/display/DisplayObject.js (Line 97)
