Members

alpha :Number

The alpha value of this DisplayObject. A value of 1 is fully opaque. A value of 0 is transparent.
Please note that an object with an alpha value of 0 is skipped during the render pass.

The value of this property does not reflect any alpha values set further up the display list.
To obtain that value please see the worldAlpha property.

Inherited From:

• PIXI.DisplayObject#alpha

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

cacheAsBitmap :Boolean

Sets if this DisplayObject should be cached as a bitmap.

When invoked it will take a snapshot of the DisplayObject, as it is at that moment, and store it
in a RenderTexture. This is then used whenever this DisplayObject is rendered. It can provide a
performance benefit for complex, but static, DisplayObjects. I.e. those with lots of children.

Cached Bitmaps do not track their parents. If you update a property of this DisplayObject, it will not
re-generate the cached bitmap automatically. To do that you need to call DisplayObject.updateCache.

To remove a cached bitmap, set this property to null.

• PIXI.DisplayObject#cacheAsBitmap

<readonly> children :Array.<DisplayObject>

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

Type:

• Array.<DisplayObject>

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

filterArea :Rectangle

The rectangular area used by filters when rendering a shader for this DisplayObject.

Inherited From:

• PIXI.DisplayObject#filterArea

Source - pixi/display/DisplayObject.js, line 195

filters :Array

Sets the filters for this DisplayObject. This is a WebGL only feature, and is ignored by the Canvas
Renderer. A filter is a shader applied to this DisplayObject. You can modify the placement of the filter
using DisplayObject.filterArea.

To remove filters, set this property to null.

Note: You cannot have a filter set, and a MULTIPLY Blend Mode active, at the same time. Setting a
filter will reset this DisplayObjects blend mode to NORMAL.

Inherited From:

• PIXI.DisplayObject#filters

Source - pixi/display/DisplayObject.js, line 710

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 600

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:

• PIXI.DisplayObject#hitArea

Source - pixi/display/DisplayObject.js, line 89

ignoreChildInput :Boolean

If ignoreChildInput is false it will allow this objects children to be considered as valid for Input events.

If this property is true then the children will not be considered as valid for Input events.

Note that this property isn't recursive: only immediate children are influenced, it doesn't scan further down.

Source - pixi/display/DisplayObjectContainer.js, line 26

mask :PIXIGraphics

Sets a mask for this DisplayObject. A mask is an instance of a Graphics object.
When applied it limits the visible area of this DisplayObject to the shape of the mask.
Under a Canvas renderer it uses shape clipping. Under a WebGL renderer it uses a Stencil Buffer.
To remove a mask, set this property to null.

Inherited From:

• PIXI.DisplayObject#mask

Source - pixi/display/DisplayObject.js, line 675

<readonly> parent :PIXIDisplayObjectContainer

The parent DisplayObjectContainer that this DisplayObject is a child of.
All DisplayObjects must belong to a parent in order to be rendered.
The root parent is the Stage object. This property is set automatically when the
DisplayObject is added to, or removed from, a DisplayObjectContainer.

Inherited From:

• PIXI.DisplayObject#parent

Source - pixi/display/DisplayObject.js, line 107

pivot :PIXIPoint

The pivot point of this DisplayObject that it rotates around. The values are expressed
in pixel values.

Inherited From:

• PIXI.DisplayObject#pivot

Source - pixi/display/DisplayObject.js, line 43

position :PIXIPoint

The coordinates, in pixels, of this DisplayObject, relative to its parent container.

The value of this property does not reflect any positioning happening further up the display list.
To obtain that value please see the worldPosition property.

Inherited From:

• PIXI.DisplayObject#position

Source - pixi/display/DisplayObject.js, line 20

renderable :Boolean

Should this DisplayObject be rendered by the renderer? An object with a renderable value of
false is skipped during the render pass.

Inherited From:

• PIXI.DisplayObject#renderable

Source - pixi/display/DisplayObject.js, line 98

rotation :Number

The rotation of this DisplayObject. The value is given, and expressed, in radians, and is based on
a right-handed orientation.

The value of this property does not reflect any rotation happening further up the display list.
To obtain that value please see the worldRotation property.

Inherited From:

• PIXI.DisplayObject#rotation

Source - pixi/display/DisplayObject.js, line 51

scale :PIXIPoint

The scale of this DisplayObject. A scale of 1:1 represents the DisplayObject
at its default size. A value of 0.5 would scale this DisplayObject by half, and so on.

The value of this property does not reflect any scaling happening further up the display list.
To obtain that value please see the worldScale property.

Inherited From:

• PIXI.DisplayObject#scale

Source - pixi/display/DisplayObject.js, line 31

visible :Boolean

The visibility of this DisplayObject. A value of false makes the object invisible.
A value of true makes it visible. Please note that an object with a visible value of
false is skipped during the render pass. Equally a DisplayObject with visible false will
not render any of its children.

The value of this property does not reflect any visible values set further up the display list.
To obtain that value please see the worldVisible property.

Inherited From:

• PIXI.DisplayObject#visible

Source - pixi/display/DisplayObject.js, line 75

width :Number

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

Source - pixi/display/DisplayObjectContainer.js, line 571

<readonly> worldAlpha :Number

The multiplied alpha value of this DisplayObject. A value of 1 is fully opaque. A value of 0 is transparent.
This value is the calculated total, based on the alpha values of all parents of this DisplayObjects
in the display list.

To obtain, and set, the local alpha value, see the alpha property.
