new DisplayObject()
The base class for all objects that are rendered on the screen. This is an abstract class and should not be used on its own rather it should be extended.

Members
-
alpha :Number
-
The opacity of the object.
- Source - pixi/display/DisplayObject.js, line 46
-
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'
- Source - pixi/display/DisplayObject.js, line 355
-
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
- Source - pixi/display/DisplayObject.js, line 164
-
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'.
You cannot have a filter and a multiply blend mode active at the same time. Setting a filter will reset this objects blend mode to NORMAL.
Type:
- Array.<Filter>
- Source - pixi/display/DisplayObject.js, line 307
-
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 62
-
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.

-
<readonly> parent :PIXI.DisplayObjectContainer
-
[read-only] The display object container that contains this display object.
- Source - pixi/display/DisplayObject.js, line 79
-
pivot :Point
-
The pivot point of the displayObject that it rotates around
- Source - pixi/display/DisplayObject.js, line 30
-
position :Point
-
The coordinate of the object relative to the local coordinates of the parent.
- Source - pixi/display/DisplayObject.js, line 14
-
renderable :Boolean
-
Can this object be rendered
- Source - pixi/display/DisplayObject.js, line 71
-
rotation :Number
-
The rotation of the object in radians.
- Source - pixi/display/DisplayObject.js, line 38
-
scale :Point
-
The scale factor of the object.
- Source - pixi/display/DisplayObject.js, line 22
-
<readonly> stage :Stage
-
[read-only] The stage the display object is connected to, or undefined if it is not connected to the stage.
- Source - pixi/display/DisplayObject.js, line 88
-
visible :Boolean
-
The visibility of the object.
- Source - pixi/display/DisplayObject.js, line 54
-
<readonly> worldAlpha :Number
-
[read-only] The multiplied alpha of the displayObject
- Source - pixi/display/DisplayObject.js, line 97
-
<readonly> worldPosition :Point
-
The position of the Display Object based on the world transform. This value is updated at the end of updateTransform and takes all parent transforms into account.
- Source - pixi/display/DisplayObject.js, line 116
-
<readonly> worldRotation :Number
-
The rotation of the Display Object, in radians, based on the world transform. This value is updated at the end of updateTransform and takes all parent transforms into account.
- Source - pixi/display/DisplayObject.js, line 136
-
<readonly> worldScale :Point
-
The scale of the Display Object based on the world transform. This value is updated at the end of updateTransform and takes all parent transforms into account.
- Source - pixi/display/DisplayObject.js, line 126
-
worldVisible :Boolean
-
[read-only] Indicates if the sprite is globally visible.
- Source - pixi/display/DisplayObject.js, line 258
-
x :Number
-
The position of the displayObject on the x axis relative to the local coordinates of the parent.
- Source - pixi/display/DisplayObject.js, line 723
-
y :Number
-
The position of the displayObject on the y axis relative to the local coordinates of the parent.
- Source - pixi/display/DisplayObject.js, line 741
Methods
-
destroy()
-
Destroy this DisplayObject. Removes all references to transformCallbacks, its parent, the stage, filters, bounds, mask and cached Sprites.
- Source - pixi/display/DisplayObject.js, line 223
-
generateTexture(resolution, scaleMode, renderer) → {PIXI.Texture}
-
Useful function that returns a texture of the displayObject object that can then be used to create sprites This can be quite useful if your displayObject is static / complicated and needs to be reused multiple times.
Parameters:
Name Type Description resolution
Number The resolution of the texture being generated
scaleMode
Number See {{#crossLink "PIXI/scaleModes:property"}}PIXI.scaleModes{{/crossLink}} for possible values
renderer
PIXI.CanvasRenderer | PIXI.WebGLRenderer The renderer used to generate the texture.
Returns:
a texture of the graphics object
- Source - pixi/display/DisplayObject.js, line 542
-
getBounds(matrix) → {Rectangle}
-
Retrieves the bounds of the displayObject as a rectangle object
Parameters:
Name Type Description matrix
Matrix -
Returns:
Rectangle -the rectangular bounding area
- Source - pixi/display/DisplayObject.js, line 498
-
getLocalBounds() → {Rectangle}
-
Retrieves the local bounds of the displayObject as a rectangle object
Returns:
Rectangle -the rectangular bounding area
- Source - pixi/display/DisplayObject.js, line 511
-
preUpdate()
-
Empty, to be overridden by classes that require it.
- Source - pixi/display/DisplayObject.js, line 533
-
setStageReference(stage)
