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.

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 - gameobjects/components/LifeSpan.js, line 50
-
alpha :Number
-
The opacity of the object.

-
anchor :Phaser.Point
-
The anchor value of this BitmapText.
- Source - 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 - 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 - gameobjects/components/Core.js, line 186
- See:
-
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 itsrenderable
property set tofalse
. 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 - 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 benull
.To enable this Game Object for physics you need to call
game.physics.enable(object, system)
whereobject
is this object andsystem
is the Physics system you are using. If none is given it defaults toPhaser.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.

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 - gameobjects/components/FixedToCamera.js, line 86
-
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
istrue
.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.

-
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 havefixedToCamera
enabled on them.- Inherited From:

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.

-
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

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

method.Very handy for particles, bullets, collectibles, or any other short-lived entity.
- Inherited From:
- Source - gameobjects/components/LifeSpan.js, line 65
-
mask :PIXI.Graphics
-
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 object. This allows for much faster masking in canvas as it utilises shape clipping. To remove a mask, set this property to null.
- Inherited From:

-
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.

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.
