A BitmapText object will create a line or multiple lines of text using bitmap font.

The primary advantage of this class over Text is that all of your textures are pre-generated and loading, meaning that rendering is fast, and changing text has no performance implications.

Supporting character sets other than latin, such as CJK languages, may be impractical due to the number of characters.

To split a line you can use '\n', '\r' or '\r\n' in your string.

PixiJS can auto-generate fonts on-the-fly using BitmapFont or use fnt files provided by: http://www.angelcode.com/products/bmfont/ for Windows or http://www.bmglyph.com/ for Mac.

A BitmapText can only be created when the font is loaded.

// in this case the font is in a file called 'desyrel.fnt'
let bitmapText = new PIXI.BitmapText("text using a fancy font!", {
  fontName: "Desyrel",
  fontSize: 35,
  align: "right"
});

Accessors

Protected _tempDisplayObjectParent

  • member

    {PIXI.Container}

    Returns TemporaryDisplayObject

align

  • The alignment of the BitmapText object.

    member

    {string}

    default

    'left'

    Returns TextStyleAlign

  • The alignment of the BitmapText object.

    Parameters

    Returns void

anchor

  • The anchor sets the origin point of the text.

    The default is (0,0), this means the text's origin is the top left.

    Setting the anchor to (0.5,0.5) means the text's origin is centered.

    Setting the anchor to (1,1) would mean the text's origin point will be the bottom right corner.

    member

    {PIXI.Point | number}

    Returns ObservablePoint<any>

  • The anchor sets the origin point of the text.

    The default is (0,0), this means the text's origin is the top left.

    Setting the anchor to (0.5,0.5) means the text's origin is centered.

    Setting the anchor to (1,1) would mean the text's origin point will be the bottom right corner.

    Parameters

    Returns void

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

fontName

  • get fontName(): string
  • set fontName(value: string): void
  • The name of the BitmapFont.

    member

    {string}

    Returns string

  • The name of the BitmapFont.

    Parameters

    • value: string

    Returns void

fontSize

  • get fontSize(): number
  • set fontSize(value: number): void
  • The size of the font to display.

    member

    {number}

    Returns number

  • The size of the font to display.

    Parameters

    • value: number

    Returns void

height

  • get height(): number
  • set height(value: number): void
  • The height of the Container, setting this will actually modify the scale to achieve the value set

    member

    {number}

    Returns number

  • The height of the Container, setting this will actually modify the scale to achieve the value set

    Parameters

    • value: number

    Returns void

letterSpacing

  • get letterSpacing(): number
  • set letterSpacing(value: number): void
  • Additional space between characters.

    member

    {number}

    Returns number

    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.

addListener

calculateBounds

  • calculateBounds(): void
  • Recalculates the bounds of the container.

    This implementation will automatically fit the children's bounds into the calculation. Each child's bounds is limited to its mask's bounds or filterArea, if any is applied.

    Returns void

destroy

  • Removes all internal references and listeners as well as removes children from the display list. Do not use a Container after calling destroy.

    Parameters

    Returns void

    Returns boolean

    current parent

eventNames

  • eventNames(): (string | symbol)[]
  • 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.

render

  • Renders the object using the WebGL renderer.

    The [_render]{@link PIXI.Container#_render} method is be overriden for rendering the contents of the container itself. This render method will invoke it, and also invoke the render methods of all children afterward.

    If renderable or visible is false or if worldAlpha is not positive, this implementation will entirely skip rendering. See PIXI.DisplayObject for choosing between renderable or visible. Generally, setting alpha to zero is not recommended for purely skipping rendering.

    When your scene becomes large (especially when it is larger than can be viewed in a single screen), it is advised to employ culling to automatically skip rendering objects outside of the current screen. The @pixi-essentials/cull and pixi-cull packages do this out of the box.

    The [renderAdvanced]{@link PIXI.Container#renderAdvanced} method is internally used when when masking or filtering is applied on a container. This does, however, break batching and can affect performance when masking and filtering is applied extensively throughout the scene graph.
