Class: Text

PIXI.Text

A Text Object will create a line or multiple lines of text.

The text is created using the Canvas API.

The primary advantage of this class over BitmapText is that you have great control over the style of the next, which you can change at runtime.

The primary disadvantages is that each piece of text has it's own texture, which can use more memory. When text changes, this texture has to be re-generated and re-uploaded to the GPU, taking up time.

To split a line you can use '\n' in your text string, or, on the style object, change its wordWrap property to true and and give the wordWrapWidth property a value.

A Text can be created directly from a string and a style object, which can be generated here.

let text = new PIXI.Text('This is a PixiJS text',{fontFamily : 'Arial', fontSize: 24, fill : 0xff1010, align : 'center'});

new PIXI.Text (text, style, canvas)

Name Type Description
text string

The string that you would like the text to display

Members

_accessibleActive boolean inherited

TODO
  • Needs docs.

_accessibleDiv boolean inherited

TODO
  • Needs docs.

_bounds PIXI.Bounds protected inherited

The bounds object, this is used to calculate and store the bounds of the displayObject.

_cachedTint number protected inherited

Cached tint value so we can tell when the tint is changed.

_destroyed boolean protected inherited

If the object has been destroyed via destroy(). If true, it should not be used.

_lastSortedIndex number protected inherited

Which index in the children array the display component was before the previous zIndex sort. Used by containers to help sort objects with the same zIndex, by using previous array index as the decider.

_mask PIXI.Graphics | PIXI.Sprite protected inherited

The original, cached mask of the object.

_resolution number

The resolution / device pixel ratio of the canvas. This is set to automatically match the renderer resolution by default, but can be overridden by setting manually.

Default Value:
  • 1

_tempDisplayObjectParent PIXI.DisplayObject protected inherited

_tintedCanvas HTMLCanvasElement protected inherited

Cached tinted texture.

_zIndex number protected inherited

The zIndex of the displayObject. A higher value will mean it will be rendered on top of other displayObjects within the same container.

accessible boolean inherited

Flag for if the object is accessible. If true AccessibilityManager will overlay a shadow div with attributes set

accessibleHint string inherited

Sets the aria-label attribute of the shadow div

accessibleTitle string nullable inherited

Sets the title attribute of the shadow div If accessibleTitle AND accessibleHint has not been this will default to 'displayObject [tabIndex]'

alpha number inherited

The opacity of the object.

The anchor sets the origin point of the text. The default value is taken from the Texture and passed to the constructor.

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.

If you pass only single parameter, it will set both x and y to the same value as shown in the example below.

Example
const sprite = new PIXI.Sprite(texture);
sprite.anchor.set(0.5); // This will set the origin to center. (0.5) is same as (0.5, 0.5).

angle number inherited

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.

blendMode number inherited

The blend mode to be applied to the sprite. Apply a value of PIXI.BLEND_MODES.NORMAL to reset the blend mode.

Default Value:
  • PIXI.BLEND_MODES.NORMAL
See:

buttonMode boolean inherited

If enabled, the mouse cursor use the pointer behavior when hovered over the displayObject if it is interactive Setting this changes the 'cursor' property to 'pointer'.

Example
const sprite = new PIXI.Sprite(texture);
sprite.interactive = true;
sprite.buttonMode = true;

cacheAsBitmap boolean inherited

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

IMPORTANT GOTCHA - Make sure that all your textures are preloaded BEFORE setting this property to true as it will take a snapshot of what is currently there. If the textures have not loaded then they will not appear.

canvas HTMLCanvasElement

The canvas element that everything is drawn to

children Array.<PIXI.DisplayObject> readonly inherited

The array of children of this container.

context CanvasRenderingContext2D

The canvas 2d context that everything is drawn with

cursor string inherited

This defines what cursor mode is used when the mouse cursor is hovered over the displayObject.

See:
Example
const sprite = new PIXI.Sprite(texture);
sprite.interactive = true;
sprite.cursor = 'wait';

filterArea PIXI.Rectangle nullable inherited

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

Also works as an interaction mask.

filters Array.<PIXI.Filter> nullable inherited

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'.

height number overrides

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

Interaction shape. Children will be hit first, then this shape will be checked. Setting this will cause this shape to be checked in hit tests rather than the displayObject's bounds.

Example
const sprite = new PIXI.Sprite(texture);
sprite.interactive = true;
sprite.hitArea = new PIXI.Rectangle(0, 0, 100, 100);

interactive boolean inherited

Enable interaction events for the DisplayObject. Touch, pointer and mouse events will not be emitted unless interactive is set to true.

Example
const sprite = new PIXI.Sprite(texture);
sprite.interactive = true;
sprite.on('tap', (event) => {
   //handle event
});

interactiveChildren boolean inherited

Determines if the children to the displayObject can be clicked/touched Setting this to false allows PixiJS to bypass a recursive hitTest function

isSprite boolean inherited

used to fast check if a sprite is.. a sprite!

localTransform PIXI.Matrix readonly inherited

Current transform of the object based on local factors: position, scale, other stuff.

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.

TODO
  • At the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as 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;

name string inherited

The instance name of the object.

parent PIXI.Container readonly inherited

The display object container that contains this display object.

The pivot point of the displayObject that it rotates around. Assignment by value since pixi-v4.

pluginName string inherited

Plugin that is responsible for rendering this element. Allows to customize the rendering process without overriding '_render' & '_renderCanvas' methods.

Default Value:
  • 'sprite'

The coordinate of the object relative to the local coordinates of the parent. Assignment by value since pixi-v4.

renderable boolean inherited

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

Only affects recursive calls from parent. You can ask for bounds manually.

resolution number

The resolution / device pixel ratio of the canvas. This is set to automatically match the renderer resolution by default, but can be overridden by setting manually.

Default Value:
  • 1

rotation number inherited

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

roundPixels boolean inherited

If true PixiJS will Math.floor() x/y values when rendering, stopping pixel interpolation. Advantages can include sharper image quality (like text) and faster rendering on canvas. The main disadvantage is movement of objects may appear less smooth. To set the global default, change PIXI.settings.ROUND_PIXELS

Default Value:
  • false

The scale factor of the object. Assignment by value since pixi-v4.

The shader that will be used to render the sprite. Set to null to remove a current shader.

The skew factor for the object in radians. Assignment by value since pixi-v4.

sortableChildren boolean inherited

If set to true, the container will sort its children by zIndex value when updateTransform() is called, or manually if sortChildren() is called.

This actually changes the order of elements in the array, so should be treated as a basic solution that is not performant compared to other solutions, such as @link https://github.com/pixijs/pixi-display

Also be aware of that this may not work nicely with the addChildAt() function, as the zIndex sorting may cause the child to automatically sorted to another position.

See:

sortDirty boolean inherited

Should children be sorted by zIndex at the next updateTransform call. Will get automatically set to true if a new child is added, or if a child's zIndex changes.

style object | PIXI.TextStyle

Set the style of the text. Set up an event listener to listen for changes on the style object and mark the text as dirty.

text string

Set the copy for the text object. To split a line you can use '\n'.

The texture that the sprite is using

tint number inherited

The tint applied to the sprite. This is a hex value. A value of 0xFFFFFF will remove any tint effect.

Default Value:
  • 0xFFFFFF

World transform and local transform of this object. This will become read-only later, please do not assign anything there unless you know what are you doing.

visible boolean inherited

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

Only affects recursive calls from parent. You can ask for bounds or call updateTransform manually.

width number overrides

The width of the Text, setting this will actually modify the scale to achieve the value set

worldAlpha number readonly inherited

The multiplied alpha of the displayObject.

worldTransform PIXI.Matrix readonly inherited

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

worldVisible boolean readonly inherited

Indicates if the object is globally visible.

x number inherited

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

y number inherited

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

zIndex number inherited

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 displayObjects within the same container.
