Constructor

PIXI. Spine

new Spine(url)

A class that enables the you to import and run your spine animations in pixi. Spine animation data needs to be loaded using the PIXI.AssetLoader or PIXI.SpineLoader before it can be used by this class See example 12 (http://www.goodboydigital.com/pixijs/examples/12/) to see a working example and check out the source

Parameters
Name Type Description
url String

The url of the spine anim file to be used

Source code: pixi/extras/PIXISpine.js, line 62

Extends

Public Properties

alpha : number

The opacity of the object.

Inherited From
Source code: pixi/display/DisplayObject.js, line 65

autoUpdate : boolean

If this flag is set to true, the spine animation will be autoupdated every time the object id drawn. The down side of this approach is that the delta time is automatically calculated and you could miss out on cool effects like slow motion, pause, skip ahead and the sorts. Most of these effects can be achieved even with autoupdate enabled but are harder to achieve.

Default Value
  • true
Source code: pixi/extras/PIXISpine.js, line 124

buttonMode : boolean

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

Inherited From
Source code: pixi/display/DisplayObject.js, line 90

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 436

[readonly] children : Array.<DisplayObject>

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

Type
Inherited From
Source code: pixi/display/DisplayObjectContainer.js, line 17

filterArea : PIXI.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 180

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'

Type
  • Array.<Filter>
Inherited From
Source code: pixi/display/DisplayObject.js, line 400

height : number

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

Inherited From
Source code: pixi/display/DisplayObjectContainer.js, line 63

hitArea : PIXI.Rectangle | PIXI.Circle | PIXI.Ellipse | PIXI.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
Inherited From
Source code: 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.

Inherited From
Source code: pixi/display/DisplayObject.js, line 380

[readonly] parent : PIXI.DisplayObjectContainer

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

Inherited From

scale : PIXI.Point

The scale factor of the object.

Inherited From
Source code: pixi/display/DisplayObject.js, line 22

[readonly] stage : PIXI.Stage

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

Inherited From
Source code: pixi/display/DisplayObject.js, line 115

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.
