Accessors

Protected _tempDisplayObjectParent

  • member

    {PIXI.Container}

    Returns TemporaryDisplayObject

angle

  • get angle(): number
  • set angle(value: number): void
  • The angle of the object in degrees. 'rotation' and 'angle' have the same effect on a display object; rotation is in radians, angle is in degrees.

    member

    {number}

    Returns number

  • The angle of the object in degrees. 'rotation' and 'angle' have the same effect on a display object; rotation is in radians, angle is in degrees.

    Parameters

    • value: number

    Returns void

localTransform

  • get localTransform(): Matrix
  • Current transform of the object based on local factors: position, scale, other stuff.

    member

    {PIXI.Matrix}

    readonly

    Returns Matrix

mask

  • 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 PixiJS a regular mask must be a PIXI.Graphics or a PIXI.Sprite object. This allows for much faster masking in canvas as it utilities shape clipping. To remove a mask, set this property to null.

    For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.

    example

    const graphics = new PIXI.Graphics(); graphics.beginFill(0xFF3300); graphics.drawRect(50, 250, 100, 100); graphics.endFill();

    const sprite = new PIXI.Sprite(texture); sprite.mask = graphics;

    todo

    At the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as mask.

    member

    {PIXI.Container|PIXI.MaskData|null}

    Returns null | Container | MaskData

  • 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 PixiJS a regular mask must be a PIXI.Graphics or a PIXI.Sprite object. This allows for much faster masking in canvas as it utilities shape clipping. To remove a mask, set this property to null.

    For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.

zIndex

  • get zIndex(): number
  • set zIndex(value: number): void
  • The zIndex of the displayObject.

    If a container has the sortableChildren property set to true, children will be automatically sorted by zIndex value; a higher value will mean it will be moved towards the end of the array, and thus rendered on top of other display objects within the same container.

    Returns DisplayObject

    current parent

  • Return an array listing the events for which the emitter has registered listeners.

    Returns (string | symbol)[]

getBounds

  • Calculates and returns the (world) bounds of the display object as a Rectangle.

    This method is expensive on containers with a large subtree (like the stage). This is because the bounds of a container depend on its children's bounds, which recursively causes all bounds in the subtree to be recalculated. The upside, however, is that calling getBounds once on a container will indeed update the bounds of all children (the whole subtree, in fact). This side effect should be exploited by using displayObject._bounds.getRectangle() when traversing through all the bounds in a scene graph. Otherwise, calling getBounds on each object in a subtree will cause the total cost to increase quadratically as its height increases.

    • The transforms of all objects in a container's subtree and of all ancestors are updated.
    • The world bounds of all display objects in a container's subtree will also be recalculated.

    The _bounds object stores the last calculation of the bounds. You can use to entirely skip bounds calculation if needed.

    const lastCalculatedBounds = displayObject._bounds.getRectangle(optionalRect);
    

    Do know that usage of getLocalBounds can corrupt the _bounds of children (the whole subtree, actually). This is a known issue that has not been solved. See [getLocalBounds]{@link PIXI.DisplayObject#getLocalBounds} for more details.

    getBounds should be called with skipUpdate equal to true in a render() call. This is because the transforms are guaranteed to be update-to-date. In fact, recalculating inside a render() call may cause corruption in certain cases.
