Constructor

Phaser. BitmapText

new BitmapText(game, x, y, font, text, size, align)

BitmapText objects work by taking a texture file and an XML or JSON file that describes the font structure. It then generates a new Sprite object for each letter of the text, proportionally spaced out and aligned to match the font structure.

BitmapText objects are less flexible than Text objects, in that they have less features such as shadows, fills and the ability to use Web Fonts, however you trade this flexibility for rendering speed. You can also create visually compelling BitmapTexts by processing the font texture in an image editor, applying fills and any other effects required.

To create multi-line text insert \r, \n or \r\n escape codes into the text string.

If you are having performance issues due to the volume of sprites being rendered, and do not require the text to be constantly updating, you can use BitmapText.generateTexture to create a static texture from this BitmapText.

To create a BitmapText data files you can use:

BMFont (Windows, free): http://www.angelcode.com/products/bmfont/ Glyph Designer (OS X, commercial): http://www.71squared.com/en/glyphdesigner Littera (Web-based, free): http://kvazars.com/littera/

For most use cases it is recommended to use XML. If you wish to use JSON, the formatting should be equal to the result of converting a valid XML file through the popular X2JS library. An online tool for conversion can be found here: http://codebeautify.org/xmltojson

If you were using an older version of Phaser (< 2.4) and using the DOMish parser hack, please remove this. It isn't required any longer.

Parameters
Name Type Argument Default Description
game Phaser.Game

A reference to the currently running game.
x number

X coordinate to display the BitmapText object at.
y number

Y coordinate to display the BitmapText object at.
font string

The key of the BitmapText as stored in Phaser.Cache.
text string <optional>
 ''

The text that will be rendered. This can also be set later via BitmapText.text.
size number <optional>
 32

The size the font will be rendered at in pixels.
align string <optional>
 'left'

The alignment of multi-line text. Has no effect if there is only one line of text.
Source code: gameobjects/BitmapText.js (Line 54)

Public Properties

align : string

Alignment for multi-line text ('left', 'center' or 'right'), does not affect single lines of text.

Source code: gameobjects/BitmapText.js (Line 534)

alive : boolean

A useful flag to control if the Game Object is alive or dead.

This is set automatically by the Health components damage method should the object run out of health. Or you can toggle it via your game code.

This property is mostly just provided to be used by your game - it doesn't effect rendering or logic updates. However you can use Group.getFirstAlive in conjunction with this property for fast object pooling and recycling.

Inherited From
Default Value
  • true
Source code: gameobjects/components/LifeSpan.js (Line 50)

anchor : Phaser.Point

The anchor value of this BitmapText.

Source code: gameobjects/BitmapText.js (Line 92)

angle : number

The angle property is the rotation of the Game Object in degrees from its original orientation.

Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.

Values outside this range are added to or subtracted from 360 to obtain a value within the range. For example, the statement player.angle = 450 is the same as player.angle = 90.

If you wish to work in radians instead of degrees you can use the property rotation instead. Working in radians is slightly faster as it doesn't have to perform any calculations.

Inherited From
Source code: gameobjects/components/Angle.js (Line 29)

animations : Phaser.AnimationManager

If the Game Object is enabled for animation (such as a Phaser.Sprite) this is a reference to its AnimationManager instance. Through it you can create, play, pause and stop animations.

Inherited From
Source code: gameobjects/components/Core.js (Line 193)

autoCull : boolean

A Game Object with autoCull set to true will check its bounds against the World Camera every frame. If it is not intersecting the Camera bounds at any point then it has its renderable property set to false. This keeps the Game Object alive and still processing updates, but forces it to skip the render step entirely.

This is a relatively expensive operation, especially if enabled on hundreds of Game Objects. So enable it only if you know it's required, or you have tested performance and find it acceptable.

Inherited From
Source code: gameobjects/components/AutoCull.js (Line 28)

body : Phaser.Physics.Arcade.Body | Phaser.Physics.P2.Body | Phaser.Physics.Ninja.Body | null

body is the Game Objects physics body. Once a Game Object is enabled for physics you access all associated properties and methods via it.

By default Game Objects won't add themselves to any physics system and their body property will be null.

To enable this Game Object for physics you need to call game.physics.enable(object, system) where object is this object and system is the Physics system you are using. If none is given it defaults to Phaser.Physics.Arcade.

You can alternatively call game.physics.arcade.enable(object), or add this Game Object to a physics enabled Group.

Important: Enabling a Game Object for P2 or Ninja physics will automatically set its anchor property to 0.5, so the physics body is centered on the Game Object.

If you need a different result then adjust or re-create the Body shape offsets manually or reset the anchor after enabling physics.

Type
Inherited From
Source code: gameobjects/components/PhysicsBody.js (Line 91)

bottom : number

The sum of the y and height properties. This is the same as y + height - offsetY.

Inherited From
Source code: gameobjects/components/Bounds.js (Line 168)

cameraOffset : Phaser.Point

The x/y coordinate offset applied to the top-left of the camera that this Game Object will be drawn at if fixedToCamera is true.

The values are relative to the top-left of the camera view and in addition to any parent of the Game Object on the display list.

Inherited From
Source code: gameobjects/components/FixedToCamera.js (Line 86)

centerX : number

The center x coordinate of the Game Object. This is the same as (x - offsetX) + (width / 2).

Inherited From
Source code: gameobjects/components/Bounds.js (Line 58)

centerY : number

The center y coordinate of the Game Object. This is the same as (y - offsetY) + (height / 2).

Inherited From
Source code: gameobjects/components/Bounds.js (Line 80)

checkWorldBounds : boolean

If this is set to true the Game Object checks if it is within the World bounds each frame.

When it is no longer intersecting the world bounds it dispatches the onOutOfBounds event.

If it was previously out of bounds but is now intersecting the world bounds again it dispatches the onEnterBounds event.

It also optionally kills the Game Object if outOfBoundsKill is true.

When checkWorldBounds is enabled it forces the Game Object to calculate its full bounds every frame.

This is a relatively expensive operation, especially if enabled on hundreds of Game Objects. So enable it only if you know it's required, or you have tested performance and find it acceptable.

[readonly] children : Array.<DisplayObject>

[read-only] The array of children of this container.

Source code: gameobjects/components/Core.js (Line 167)

data : Object

An empty Object that belongs to this Game Object. This value isn't ever used internally by Phaser, but may be used by your own code, or by Phaser Plugins, to store data that needs to be associated with the Game Object, without polluting the Game Object directly.

Source code: gameobjects/components/Destroy.js (Line 22)

dirty : boolean

The dirty state of this object.

Source code: gameobjects/BitmapText.js (Line 153)

All Phaser Game Objects have an Events class which contains all of the events that are dispatched when certain things happen to this Game Object, or any of its components.

Inherited From
Source code: gameobjects/components/Core.js (Line 185)
See

exists : boolean

Controls if this Game Object is processed by the core game loop. If this Game Object has a physics body it also controls if its physics body is updated or not. When exists is set to false it will remove its physics body from the physics world if it has one. It also toggles the visible property to false as well.

Setting exists to true will add its physics body back in to the physics world, if it has one. It will also set the visible property to true.

Inherited From
Source code: gameobjects/components/Core.js (Line 284)

fixedToCamera : boolean

A Game Object that is "fixed" to the camera uses its x/y coordinates as offsets from the top left of the camera during rendering.

The values are adjusted at the rendering stage, overriding the Game Objects actual world position.

The end result is that the Game Object will appear to be 'fixed' to the camera, regardless of where in the game world the camera is viewing. This is useful if for example this Game Object is a UI item that you wish to be visible at all times regardless where in the world the camera is.

The offsets are stored in the cameraOffset property.

Note that the cameraOffset values are in addition to any parent of this Game Object on the display list.

Be careful not to set fixedToCamera on Game Objects which are in Groups that already have fixedToCamera enabled on them.

Inherited From
Source code: gameobjects/components/FixedToCamera.js (Line 56)

font : string

The font the text will be rendered in, i.e. 'Arial'. Must be loaded in the browser before use.

Source code: gameobjects/BitmapText.js (Line 578)

fontSize : number

The size of the font in pixels.

Source code: gameobjects/BitmapText.js (Line 601)

[readonly] fresh : boolean

A Game Object is considered fresh if it has just been created or reset and is yet to receive a renderer transform update. This property is mostly used internally by the physics systems, but is exposed for the use of plugins.

Inherited From
Source code: gameobjects/components/Core.js (Line 248)

game : Phaser.Game

A reference to the currently running Game.

Inherited From
Source code: gameobjects/components/Core.js (Line 142)

height : number

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

Inherited From
Source code: pixi/display/DisplayObjectContainer.js (Line 72)

ignoreChildInput : boolean

If ignoreChildInput is false it will allow this objects children to be considered as valid for Input events.

If this property is true then the children will not be considered as valid for Input events.

Note that this property isn't recursive: only immediate children are influenced, it doesn't scan further down.

Inherited From
Source code: pixi/display/DisplayObjectContainer.js (Line 26)

[readonly] inCamera : boolean

Checks if the Game Objects bounds intersect with the Game Camera bounds. Returns true if they do, otherwise false if fully outside of the Cameras bounds.

Inherited From
Source code: gameobjects/components/AutoCull.js (Line 37)

input : Phaser.InputHandler | null

The Input Handler for this Game Object.

By default it is disabled. If you wish this Game Object to process input events you should enable it with: inputEnabled = true.

After you have done this, this property will be a reference to the Phaser InputHandler.

Type
Inherited From
Source code: gameobjects/components/InputEnabled.js (Line 24)

inputEnabled : boolean

By default a Game Object won't process any input events. By setting inputEnabled to true a Phaser.InputHandler is created for this Game Object and it will then start to process click / touch events and more.

You can then access the Input Handler via this.input.

Note that Input related events are dispatched from this.events, i.e.: events.onInputDown.

If you set this property to false it will stop the Input Handler from processing any more input events.

If you want to temporarily disable input for a Game Object, then it's better to set input.enabled = false, as it won't reset any of the Input Handlers internal properties. You can then toggle this back on as needed.

Inherited From
Source code: gameobjects/components/InputEnabled.js (Line 42)

[readonly] inWorld : boolean

Checks if the Game Objects bounds are within, or intersect at any point with the Game World bounds.

Inherited From
Source code: gameobjects/components/InWorld.js (Line 129)

key : string | Phaser.RenderTexture | Phaser.BitmapData | Phaser.Video | PIXI.Texture

The key of the image or texture used by this Game Object during rendering. If it is a string it's the string used to retrieve the texture from the Phaser Image Cache. It can also be an instance of a RenderTexture, BitmapData, Video or PIXI.Texture. If a Game Object is created without a key it is automatically assigned the key __default which is a 32x32 transparent PNG stored within the Cache. If a Game Object is given a key which doesn't exist in the Image Cache it is re-assigned the key __missing which is a 32x32 PNG of a green box with a line through it.

left : number

The left coordinate of the Game Object. This is the same as x - offsetX.

Inherited From
Source code: gameobjects/components/Bounds.js (Line 102)

lifespan : number

The lifespan allows you to give a Game Object a lifespan in milliseconds.

Once the Game Object is 'born' you can set this to a positive value.

It is automatically decremented by the millisecond equivalent of game.time.physicsElapsed each frame. When it reaches zero it will call the kill method.

Very handy for particles, bullets, collectibles, or any other short-lived entity.

Inherited From
Source code: gameobjects/components/LifeSpan.js (Line 65)

maxWidth : number

The maximum display width of this BitmapText in pixels.

If BitmapText.text is longer than maxWidth then the lines will be automatically wrapped based on the last whitespace character found in the line.

If no whitespace was found then no wrapping will take place and consequently the maxWidth value will not be honored.

Disable maxWidth by setting the value to 0. The maximum width of this BitmapText in pixels.

Source code: gameobjects/BitmapText.js (Line 647)

name : string

A user defined name given to this Game Object. This value isn't ever used internally by Phaser, it is meant as a game level property.

Inherited From
Source code: gameobjects/components/Core.js (Line 150)

[readonly] offsetX : number

The amount the Game Object is visually offset from its x coordinate. This is the same as width * anchor.x. It will only be > 0 if anchor.x is not equal to zero.

Inherited From

alignIn(container, position, offsetX, offsetY) → {Object}

Aligns this Game Object within another Game Object, or Rectangle, known as the 'container', to one of 9 possible positions.

The container must be a Game Object, or Phaser.Rectangle object. This can include properties such as World.bounds or Camera.view, for aligning Game Objects within the world and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText, TileSprites or Buttons.

Please note that aligning a Sprite to another Game Object does not make it a child of the container. It simply modifies its position coordinates so it aligns with it.

The position constants you can use are:

Phaser.TOP_LEFT, Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_CENTER, Phaser.CENTER, Phaser.RIGHT_CENTER, Phaser.BOTTOM_LEFT, Phaser.BOTTOM_CENTER and Phaser.BOTTOM_RIGHT.

The Game Objects are placed in such a way that their bounds align with the container, taking into consideration rotation, scale and the anchor property. This allows you to neatly align Game Objects, irrespective of their position value.

The optional offsetX and offsetY arguments allow you to apply extra spacing to the final aligned position of the Game Object. For example:

sprite.alignIn(background, Phaser.BOTTOM_RIGHT, -20, -20)

Would align the sprite to the bottom-right, but moved 20 pixels in from the corner. Think of the offsets as applying an adjustment to the containers bounds before the alignment takes place. So providing a negative offset will 'shrink' the container bounds by that amount, and providing a positive one expands it.

Parameters
Name Type Argument Default Description
container Phaser.Rectangle | Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Button | Phaser.Graphics | Phaser.TileSprite

The Game Object or Rectangle with which to align this Game Object to. Can also include properties such as World.bounds or Camera.view.
position integer <optional>

The position constant. One of Phaser.TOP_LEFT (default), Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_CENTER, Phaser.CENTER, Phaser.RIGHT_CENTER, Phaser.BOTTOM_LEFT, Phaser.BOTTOM_CENTER or Phaser.BOTTOM_RIGHT.
offsetX integer <optional>
 0

A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
offsetY integer <optional>
 0

A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
Returns
Object -

This Game Object.

alignTo(parent, position, offsetX, offsetY) → {Object}

Aligns this Game Object to the side of another Game Object, or Rectangle, known as the 'parent', in one of 11 possible positions.

The parent must be a Game Object, or Phaser.Rectangle object. This can include properties such as World.bounds or Camera.view, for aligning Game Objects within the world and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText, TileSprites or Buttons.

Please note that aligning a Sprite to another Game Object does not make it a child of the parent. It simply modifies its position coordinates so it aligns with it.

The position constants you can use are:

Phaser.TOP_LEFT (default), Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_TOP, Phaser.LEFT_CENTER, Phaser.LEFT_BOTTOM, Phaser.RIGHT_TOP, Phaser.RIGHT_CENTER, Phaser.RIGHT_BOTTOM, Phaser.BOTTOM_LEFT, Phaser.BOTTOM_CENTER and Phaser.BOTTOM_RIGHT.

The Game Objects are placed in such a way that their bounds align with the parent, taking into consideration rotation, scale and the anchor property. This allows you to neatly align Game Objects, irrespective of their position value.

The optional offsetX and offsetY arguments allow you to apply extra spacing to the final aligned position of the Game Object. For example:

sprite.alignTo(background, Phaser.BOTTOM_RIGHT, -20, -20)

Would align the sprite to the bottom-right, but moved 20 pixels in from the corner. Think of the offsets as applying an adjustment to the parents bounds before the alignment takes place. So providing a negative offset will 'shrink' the parent bounds by that amount, and providing a positive one expands it.

Parameters
Name Type Argument Default Description
parent Phaser.Rectangle | Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Button | Phaser.Graphics | Phaser.TileSprite

The Game Object or Rectangle with which to align this Game Object to. Can also include properties such as World.bounds or Camera.view.

offsetX integer <optional>
 0

A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
offsetY integer <optional>
 0

A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
Returns

cleanText(text, replace) → {string}

Given a text string this will scan each character in the string to ensure it exists in the BitmapText font data. If it doesn't the character is removed, or replaced with the replace argument.

If no font data has been loaded at all this returns an empty string, as nothing can be rendered.

Parameters
Name Type Argument Default Description
text string

The text to parse.
replace string <optional>
 ''

The replacement string for any missing characters.
Returns
string -

The cleaned text string.

Source code: gameobjects/BitmapText.js (Line 311)

destroy(destroyChildren, destroyTexture)

Destroys the Game Object. This removes it from its parent group, destroys the input, event and animation handlers if present and nulls its reference to game, freeing it up for garbage collection.

If this Game Object has the Events component it will also dispatch the onDestroy event.

You can optionally also destroy the BaseTexture this Game Object is using. Be careful if you've more than one Game Object sharing the same BaseTexture.

Parameters
Name Type Argument Default Description
destroyChildren boolean <optional>
 true

Should every child of this object have its destroy method called as well?
destroyTexture boolean <optional>
 false

Destroy the BaseTexture this Game Object is using? Note that if another Game Object is sharing the same BaseTexture it will invalidate it.

kill() → {PIXI.DisplayObject}

Kills a Game Object. A killed Game Object has its alive, exists and visible properties all set to false.

It will dispatch the onKilled event. You can listen to events.onKilled for the signal.

Note that killing a Game Object is a way for you to quickly recycle it in an object pool, it doesn't destroy the object or free it up from memory.

If you don't need this Game Object any more you should call destroy instead.

Returns
PIXI.DisplayObject -

This instance.

Source code: gameobjects/components/LifeSpan.js (Line 113)

postUpdate()

Automatically called by World.preUpdate.

Source code: gameobjects/BitmapText.js (Line 198)

preUpdate() → {boolean}

Automatically called by World.preUpdate.

Returns
boolean -

True if the BitmapText was rendered, otherwise false.

Source code: gameobjects/BitmapText.js (Line 187)

purgeGlyphs() → {integer}

If a BitmapText changes from having a large number of characters to having very few characters it will cause lots of Sprites to be retained in the BitmapText._glyphs array. Although they are not attached to the display list they still take up memory while sat in the glyphs pool waiting to be re-used in the future.

If you know that the BitmapText will not grow any larger then you can purge out the excess glyphs from the pool by calling this method.

Calling this doesn't prevent you from increasing the length of the text again in the future.

Returns
integer -

The amount of glyphs removed from the pool.
