## PIXI.PIXI. DisplayObject

#### new DisplayObject()

  The base class for all objects that are rendered. Contains properties for position, scaling,
  rotation, masks and cache handling.

  This is an abstract class and should not be used on its own, rather it should be extended.

  It is used internally by the likes of PIXI.Sprite.

### 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.

  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`.

#### filterArea :Rectangle

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

  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.

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

#### 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`.

#### <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.

  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.

  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.

  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.

  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.

  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.

  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.

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

#### <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.

  Note: This property is only updated at the end of the `updateTransform` call, once per render. Until
  that happens this property will contain values based on the previous frame. Be mindful of this if
  accessing this property outside of the normal game flow, i.e. from an asynchronous event callback.

  Source - pixi/display/DisplayObject.js, line 119

#### <readonly> worldPosition :PIXIPoint

  The coordinates, in pixels, of this DisplayObject within the world.

  This property contains the calculated total, based on the positions of all parents of this
  DisplayObject in the display list.

  Note: This property is only updated at the end of the `updateTransform` call, once per render. Until
  that happens this property will contain values based on the previous frame. Be mindful of this if
  accessing this property outside of the normal game flow, i.e. from an asynchronous event callback.

  Source - pixi/display/DisplayObject.js, line 150

#### <readonly> worldRotation :Number

  The rotation, in radians, of this DisplayObject.

  This property contains the calculated total, based on the rotations of all parents of this
  DisplayObject in the display list.

  Note: This property is only updated at the end of the `updateTransform` call, once per render. Until
  that happens this property will contain values based on the previous frame. Be mindful of this if
  accessing this property outside of the normal game flow, i.e. from an asynchronous event callback.

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

#### <readonly> worldScale :PIXIPoint

  The global scale of this DisplayObject.

  This property contains the calculated total, based on the scales of all parents of this
  DisplayObject in the display list.

  Note: This property is only updated at the end of the `updateTransform` call, once per render. Until
  that happens this property will contain values based on the previous frame. Be mindful of this if
  accessing this property outside of the normal game flow, i.e. from an asynchronous event callback.

  Source - pixi/display/DisplayObject.js, line 165

#### <readonly> worldTransform :PIXIMatrix

  The current transform of this DisplayObject.

  This property contains the calculated total, based on the transforms of all parents of this
  DisplayObject in the display list.

  Note: This property is only updated at the end of the `updateTransform` call, once per render. Until
  that happens this property will contain values based on the previous frame. Be mindful of this if
  accessing this property outside of the normal game flow, i.e. from an asynchronous event callback.

  Source - pixi/display/DisplayObject.js, line 135

#### worldVisible :Boolean

  Indicates if this DisplayObject is visible, based on it, and all of its parents, `visible` property values.

  Source - pixi/display/DisplayObject.js, line 630

#### x :Number

  The horizontal position of the DisplayObject, in pixels, relative to its parent.
  If you need the world position of the DisplayObject, use `DisplayObject.worldPosition` instead.

  Source - pixi/display/DisplayObject.js, line 586

#### y :Number

  The vertical position of the DisplayObject, in pixels, relative to its parent.
  If you need the world position of the DisplayObject, use `DisplayObject.worldPosition` instead.
