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.

-
alpha :Number
-
The opacity of the object.
- Inherited From:
- Source - pixi/display/DisplayObject.js, line 65
-
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 - pixi/display/DisplayObject.js, line 376
-
<readonly> children :Array.<DisplayObject>
-
[read-only] The array of children of this container.
Type:
- Array.<DisplayObject>
-
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 - pixi/display/DisplayObject.js, line 183
-
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 - pixi/display/DisplayObject.js, line 328
-
height :Number
-
The height of the displayObjectContainer, setting this will actually modify the scale to achieve the value set
-
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 - pixi/display/DisplayObject.js, line 81
-
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.

- Source - pixi/display/DisplayObject.js, line 303

<readonly> parent :PIXI.DisplayObjectContainer

- Inherited From:
- Source - pixi/display/DisplayObject.js, line 107
-
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.

- Source - pixi/display/DisplayObject.js, line 30

transformCallbackContext :Object

The context under which the transformCallback is invoked.
