Update the bounds of the object

updateCache

Generates and updates the cached sprite for this object.

updateCachedSpriteTexture

() private

Updates texture size based on canvas size

Properties

_bounds

Rectangle private

The original, cached bounds of the object

_cacheAsBitmap

Boolean private

Cached internal flag.

_cacheIsDirty

Boolean private

Cached internal flag.

_cr

Number private

cached sin rotation and cos rotation

_currentBounds

Rectangle private

Inherited from DisplayObject but overwritten in src/pixi/display/DisplayObject.js:179

The most up-to-date bounds of the object

_interactive

Boolean private

[read-only] Whether or not the object is interactive, do not toggle directly! use the interactive property

_sr

Number private

cached sin rotation and cos rotation

_webGL

Array private

Array containing some WebGL-related properties used by the WebGL renderer.

alpha

Number

The opacity of the object.

blendMode

Number

The blend mode to be applied to the graphic shape. Apply a value of PIXI.blendModes.NORMAL to reset the blend mode.

Default: PIXI.blendModes.NORMAL;

boundsPadding

Number

The bounds' padding used for bounds calculation.

buttonMode

Boolean

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

cacheAsBitmap

Boolean private

Inherited from DisplayObject but overwritten in src/pixi/primitives/Graphics.js:137

When cacheAsBitmap is set to true the graphics object will be rendered as if it was a sprite. This is useful if your graphics element does not change often, as it will speed up the rendering of the object in exchange for taking up texture memory. It is also useful if you need the graphics object to be anti-aliased, because it will be rendered using canvas. This is not recommended if you are constantly redrawing the graphics element.

Default: false

cachedSpriteDirty

Boolean private

Used to detect if the cached sprite object needs to be updated.

children

Array

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

currentPath

Object private

Current path

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

dirty

Boolean private

Used to detect if the graphics object has changed. If this is set to true then the graphics object will be recalculated.

fillAlpha

Number

The alpha value used when filling the Graphics object.

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

filters

Array An array of filters

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'

graphicsData

Array private

Graphics data

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)

interactive

Boolean

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

Default: false

isMask

Boolean

Whether this shape is being used as a mask.

lineColor

String

The color of any lines drawn.

Default: 0

lineWidth

Number

The width (thickness) of any lines drawn.

mask

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.

parent

DisplayObjectContainer

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

pivot

Point

The pivot point of the displayObject that it rotates around

position

Point

The coordinate of the object relative to the local coordinates of the parent.

renderable

Boolean

Can this object be rendered

rotation

Number

The rotation of the object in radians.

scale

Point

The scale factor of the object.

stage

Stage

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

tint

Number

The tint applied to the graphic shape. This is a hex value. Apply a value of 0xFFFFFF to reset the tint.

Default: 0xFFFFFF

visible

Boolean

The visibility of the object.

webGLDirty

Boolean private

Used to detect if the webgl graphics object has changed. If this is set to true then the graphics object will be recalculated.

width

Number

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

worldAlpha

Number

[read-only] The multiplied alpha of the displayObject

worldTransform

Matrix private

[read-only] Current transform of the object based on world (parent) factors

worldVisible

Boolean

[read-only] Indicates if the sprite is globally visible.

x

Number

The position of the displayObject on the x axis relative to the local coordinates of the parent.

y

Number

The position of the displayObject on the y axis relative to the local coordinates of the parent.
