DisplayObject Class
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.

Methods
_renderCanvas
-
renderSession
Renders the object using the Canvas renderer
Parameters:
-
renderSessionRenderSession
_renderWebGL
-
renderSession
Renders the object using the WebGL renderer
Parameters:
-
renderSessionRenderSession
click
-
interactionData
A callback that is used when the users clicks on the displayObject with their mouse
Parameters:
-
interactionDataInteractionData
getBounds
()
Rectangle
Retrieves the bounds of the displayObject as a rectangle object
Returns:
the rectangular bounding area
getLocalBounds
()
Rectangle
Retrieves the local bounds of the displayObject as a rectangle object
Returns:
the rectangular bounding area
mousedown
-
interactionData
A callback that is used when the user clicks the mouse down over the sprite
Parameters:
-
interactionDataInteractionData
mouseout
-
interactionData
A callback that is used when the users mouse leaves the displayObject
Parameters:
-
interactionDataInteractionData
mouseover
-
interactionData
A callback that is used when the users mouse rolls over the displayObject
Parameters:
-
interactionDataInteractionData
mouseup
-
interactionData
A callback that is used when the user releases the mouse that was over the displayObject for this callback to be fired the mouse must have been pressed down over the displayObject
Parameters:
-
interactionDataInteractionData
mouseupoutside
-
interactionData
A callback that is used when the user releases the mouse that was over the displayObject but is no longer over the displayObject for this callback to be fired, The touch must have started over the displayObject
Parameters:
-
interactionDataInteractionData
setInteractive
-
interactive
[Deprecated] Indicates if the sprite will have touch and mouse interactivity. It is false by default Instead of using this function you can now simply set the interactive property to true or false
Parameters:
-
interactiveBoolean
setStageReference
-
stage
Sets the object's stage reference, the stage this object is connected to
Parameters:
-
stageStagethe stage that the object will have as its current stage reference
tap
-
interactionData
A callback that is used when the users taps on the sprite with their finger basically a touch version of click
Parameters:
-
interactionDataInteractionData
touchend
-
interactionData
A callback that is used when the user releases a touch over the displayObject
Parameters:
-
interactionDataInteractionData
touchendoutside
-
interactionData
A callback that is used when the user releases the touch that was over the displayObject for this callback to be fired, The touch must have started over the sprite
Parameters:
-
interactionDataInteractionData
touchstart
-
interactionData
A callback that is used when the user touches over the displayObject
Parameters:
-
interactionDataInteractionData
Properties
_interactive
Boolean
private
[read-only] Whether or not the object is interactive, do not toggle directly! use the interactive property
alpha
Number
The opacity of the object.
cacheAsBitmap
Boolean
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'
color
Array<>
private
[NYI] Unknown
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
dynamic
Boolean
private
[NYI] Holds whether or not this object is dynamic, for rendering optimization
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'
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
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
Boolean
Can this object be rendered
rotation
Number
The rotation of the object in radians.
stage
Stage
[read-only] The stage the display object is connected to, or undefined if it is not connected to the stage.
visible
Boolean
The visibility of the object.
worldAlpha
Number
[read-only] The multiplied alpha of the displayObject
worldTransform
Mat3
private
[read-only] Current transform of the object based on world (parent) factors
worldVisible
Boolean
[read-only] Indicates if the sprite is globaly 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.
