updateCache
()
Generates and updates the cached sprite for this object.
Properties
alpha
Float
The opacity of the object.
anchor
Point
The anchor sets the origin point of the texture. The default is 0,0 this means the texture's origin is the top left Setting than anchor to 0.5,0.5 means the textures origin is centered Setting the anchor to 1,1 would mean the textures origin points will be the bottom right corner
blendMode
Int
The blend mode to be applied to the sprite. Set to PIXI.blendModes.NORMAL to remove any blend mode.
Default: PIXI.blendModes.NORMAL;
cacheAsBitmap
Bool
Set weather or not a the display objects 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 filters simply set this property to 'null'
canvas
CanvasElement
The canvas element that everything is drawn to
children
Array[read-only] The array of children of this container.
context
CanvasRenderingContext2D
The canvas 2d context that everything is drawn with
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
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'
height
Float
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
Bool
Indicates if the sprite will have touch and mouse interactivity. It is false by default
Default: false
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.
renderable
Bool
Can this object be rendered
rotation
Float
The rotation of the object in radians.
shader
PIXI.AbstractFilter
The shader that will be used to render the texture to the stage. Set to null to remove a current shader.
Default: null
stage
Stage
[read-only] The stage the display object is connected to, or undefined if it is not connected to the stage.
tint
Int
The tint applied to the sprite. This is a hex value. A value of 0xFFFFFF will remove any tint effect.
Default: 0xFFFFFF
visible
Bool
The visibility of the object.
width
Float
The width of the displayObjectContainer, setting this will actually modify the scale to achieve the value set
worldAlpha
Float
[read-only] The multiplied alpha of the displayObject
worldVisible
Bool
[read-only] Indicates if the sprite is globaly visible.
x
Float
The position of the displayObject on the x axis relative to the local coordinates of the parent.
y
Float
The position of the displayObject on the y axis relative to the local coordinates of the parent.
