Class: DisplayObject

PIXI. DisplayObject

new PIXI.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.

Extends

  • EventEmitter

Members

alphanumber

The opacity of the object.

cacheAsBitmapboolean

Set this to true if you want this display object to be 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 'false'

filterAreaPIXI.Rectangle

The area the filter is applied to. This is used as more of an optimisation
rather than figuring out the dimensions of the displayObject each frame you can set this rectangle

filtersArray.<PIXI.AbstractFilter>

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'

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 or a PIXI.Sprite object. This allows for much faster masking in canvas as it utilises shape clipping.
To remove a mask, set this property to null.

TODO
  • For the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as mask.

readonlyparentPIXI.Container

The display object container that contains this display object.

pivotPIXI.Point

The pivot point of the displayObject that it rotates around

positionPIXI.Point

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

renderableboolean

Can this object be rendered, if false the object will not be drawn but the updateTransform
methods will still be called.

rotationnumber

The rotation of the object in radians.

scalePIXI.Point

The scale factor of the object.

The skew factor for the object in radians.

visibleboolean

The visibility of the object. If false the object will not be drawn, and
the updateTransform function will not be called.

readonlyworldAlphanumber

The multiplied alpha of the displayObject

readonlyworldTransformPIXI.Matrix

Current transform of the object based on world (parent) factors

readonlyworldVisibleboolean

Indicates if the sprite is globally visible.

xnumber

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

ynumber

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

Methods

Base destroy method for generic display objects

generateTexture(renderer, scaleMode, resolution){PIXI.Texture}

Useful function that returns a texture of the display 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.

Name Type Description
renderer PIXI.CanvasRenderer | PIXI.WebGLRenderer

The renderer used to generate the texture.

scaleMode number

See PIXI.SCALE_MODES for possible values

resolution number

The resolution of the texture being generated

Returns:
Type Description
PIXI.Texture a texture of the display object

Retrieves the bounds of the displayObject as a rectangle object

Name Type Description
matrix PIXI.Matrix
Returns:
Type Description
PIXI.Rectangle the rectangular bounding area

Retrieves the local bounds of the displayObject as a rectangle object

Returns:
Type Description
PIXI.Rectangle the rectangular bounding area

setParent(container){Container}

Set the parent Container of this DisplayObject

Name Type Description
container Container

The Container to add this DisplayObject to

Returns:
Type Description
Container The Container that this DisplayObject was added to

setTransform(x, y, scaleX, scaleY, rotation, skewX, skewY, pivotX, pivotY){PIXI.DisplayObject}

Convenience function to set the postion, scale, skew and pivot at once.

Name Type Default Description
x number 0 optional

The X position

y number 0 optional

The Y position

scaleX number 1 optional

The X scale value

scaleY number 1 optional

The Y scale value

rotation number 0 optional

The rotation

skewX number 0 optional

The X skew value

skewY number 0 optional

The Y skew value

pivotX number 0 optional

The X pivot value

pivotY number 0 optional

The Y pivot value

Returns:
Type Description
PIXI.DisplayObject

Calculates the global position of the display object

Name Type Description
position PIXI.Point

The world origin to calculate from

Returns:
Type Description
PIXI.Point A point object representing the position of this object

toLocal(position, from, point){PIXI.Point}

Calculates the local position of the display object relative to another point

Name Type Description
position PIXI.Point

The world origin to calculate from

from PIXI.DisplayObject optional

The DisplayObject to calculate the global position from

point PIXI.Point optional

A Point object in which to store the value, optional (otherwise will create a new Point)

Returns:
Type Description
PIXI.Point A point object representing the position of this object
