Members
-
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 useGroup.getFirstAlive
in conjunction with this property for fast object pooling and recycling.- Inherited From:
- Default Value:
- true
- Source - gameobjects/components/LifeSpan.js, line 50
-
<internal> alphaData :array
-
A reference to the alphaData array owned by the Emitter that emitted this Particle.
- Internal:
- This member is internal (protected) and may be modified or removed in the future.
- Source - gameobjects/Particle.js, line 51
-
anchor :Point
-
The anchor sets the origin point of the texture.
The default is 0,0 this means the texture's origin is the top left
Setting than anchor to 0.5,0.5 means the textures origin is centered
Setting the anchor to 1,1 would mean the textures origin points will be the bottom right corner- Inherited From:
- Source - pixi/display/Sprite.js, line 17
-
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 193

- Internal:
- This member is internal (protected) and may be modified or removed in the future.
- Source - gameobjects/Particle.js, line 45
-
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
-
<internal> autoScale :boolean
-
If this Particle automatically scales this is set to true by Particle.setScaleData.

-
blendMode :Number
-
The blend mode to be applied to the sprite. Set to PIXI.blendModes.NORMAL to remove any blend mode.
Warning: You cannot have a blend mode and a filter active on the same Sprite. Doing so will render the sprite invisible.
- Inherited From:
- Default Value:
- PIXI.blendModes.NORMAL;
- Source - pixi/display/Sprite.js, line 82
-
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.

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.- Inherited From:

- Source - pixi/display/Sprite.js, line 103
-
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:
- Source - gameobjects/components/FixedToCamera.js, line 56
-
frame :integer
-
Gets or sets the current frame index of the texture being used to render this Game Object.
To change the frame set
frame
to the index of the new frame in the sprite sheet you wish this Game Object to use,
for example:player.frame = 4
.If the frame index given doesn't exist it will revert to the first frame found in the texture.
If you are using a texture atlas then you should use the
frameName
property instead.If you wish to fully replace the texture being used see
loadTexture
.- Inherited From:
- Source - gameobjects/components/LoadTexture.js, line 259
-
frameName :string
-
Gets or sets the current frame name of the texture being used to render this Game Object.
To change the frame set
frameName
to the name of the new frame in the texture atlas you wish this Game Object to use,
for example:player.frameName = "idle"
.If the frame name given doesn't exist it will revert to the first frame found in the texture and throw a console warning.
If you are using a sprite sheet then you should use the
frame
property instead.If you wish to fully replace the texture being used see
loadTexture
.- Inherited From:
- Source - gameobjects/components/LoadTexture.js, line 284

height :Number
-
The height of the sprite, setting this will actually modify the scale to achieve the value set
- Inherited From:
- Source - pixi/display/Sprite.js, line 144
-
ignoreChildInput :Boolean
-
If
ignoreChildInput
isfalse
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 - pixi/display/DisplayObjectContainer.js, line 26
-
<readonly> inCamera :boolean
-
Checks if the Game Objects bounds intersect with the Game Camera bounds.

Type:
- Phaser.InputHandler | null
- Inherited From:
- Source - gameobjects/components/InputEnabled.js, line 24
-
inputEnabled :boolean
-

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:

addChild(child) → {DisplayObject}
-
Adds a child to the container.
Parameters:
Name Type Description child
DisplayObject The DisplayObject to add to the container
Returns:
The child that was added.
- Inherited From:
- Source - pixi/display/DisplayObjectContainer.js, line 42
-
addChildAt(child, index) → {DisplayObject}
-
Adds a child to the container at a specified index. If the index is out of bounds an error will be thrown
Parameters:
Name Type Description child
DisplayObject The child to add
index
Number The index to place the child in
Returns:
The child that was added.

-
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 asWorld.bounds
orCamera.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
andPhaser.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
andoffsetY
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
orCamera.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
orPhaser.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 asWorld.bounds
orCamera.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
andPhaser.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

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
orCamera.view
.position
integer <optional>
The position constant. One of
Phaser.TOP_LEFT
,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
orPhaser.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.

bringToTop() → {PIXI.DisplayObject}
-
Brings this Game Object to the top of its parents display list.
Visually this means it will render over the top of any old child in the same Group.If this Game Object hasn't been added to a custom Group then this method will bring it to the top of the Game World,
because the World is the root Group from which all Game Objects descend.Returns:
PIXI.DisplayObject -This instance.
- Inherited From:
- Source - gameobjects/components/BringToTop.js, line 24
-
contains(child) → {Boolean}
-
Determines whether the specified display object is a child of the DisplayObjectContainer instance or the instance itself.
Parameters:
Name Type Description child
DisplayObject -
Returns:
Boolean -- Inherited From:
- Source - pixi/display/DisplayObjectContainer.js, line 449
-
crop(rect, copy)
-
Crop allows you to crop the texture being used to display this Game Object.
Setting a crop rectangle modifies the core texture frame. The Game Object width and height properties will be adjusted accordingly.Cropping takes place from the top-left and can be modified in real-time either by providing an updated rectangle object to this method,
or by modifyingcropRect
property directly and then callingupdateCrop
.The rectangle object given to this method can be either a
Phaser.Rectangle
or any other object
so long as it has publicx
,y
,width
,height
,right
andbottom
properties.A reference to the rectangle is stored in
cropRect
unless thecopy
parameter istrue
,
in which case the values are duplicated to a local object.Parameters:
Name Type Argument Default Description rect
Phaser.Rectangle The Rectangle used during cropping. Pass null or no parameters to clear a previously set crop rectangle.
copy
boolean <optional>
false If false
cropRect
will be stored as a reference to the given rect. If true it will copy the rect values into a local Phaser Rectangle object stored in cropRect.- Inherited From:
- Source - gameobjects/components/Crop.js, line 49
-
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 togame
, 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.
- Inherited From:
- Source - gameobjects/components/Destroy.js, line 37
-
getBounds(matrix) → {Rectangle}
-
Returns the bounds of the Sprite as a rectangle.
The bounds calculation takes the worldTransform into account.It is important to note that the transform is not updated when you call this method.
So if this Sprite is the child of a Display Object which has had its transform
updated since the last render pass, those changes will not yet have been applied
to this Sprites worldTransform. If you need to ensure that all parent transforms
are factored into this getBounds operation then you should callupdateTransform
on the root most object in this Sprites display list first.Parameters:
Name Type Description matrix
Matrix the transformation matrix of the sprite
Returns:
Rectangle -the framing rectangle
- Inherited From:
- Source - pixi/display/Sprite.js, line 199
-
getChildAt(index) → {DisplayObject}
-
Returns the child at the specified index
Parameters:

- Inherited From:
- Source - pixi/display/DisplayObjectContainer.js, line 153
-
getChildIndex(child) → {Number}
-
Returns the index position of a child DisplayObject instance
Parameters:
Name Type Description child
DisplayObject The DisplayObject instance to identify
Returns:
Number -The index position of the child display object to identify

-
kill() → {PIXI.DisplayObject}
-
Kills a Game Object. A killed Game Object has its
alive
,exists
andvisible
properties all set to false.It will dispatch the
onKilled
event. You can listen toevents.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.
- Inherited From:
- Source - gameobjects/components/LifeSpan.js, line 113
-
loadTexture(key, frame, stopAnimation)
-
Changes the base texture the Game Object is using. The old texture is removed and the new one is referenced or fetched from the Cache.
If your Game Object is using a frame from a texture atlas and you just wish to change to another frame, then see the
frame
orframeName
properties instead.You should only use
loadTexture
if you want to replace the base texture entirely.Calling this method causes a WebGL texture update, so use sparingly or in low-intensity portions of your game, or if you know the new texture is already on the GPU.
You can use the new const
Phaser.PENDING_ATLAS
as the texture key for any sprite.
Doing this then sets the key to be theframe
argument (the frame is set to zero).This allows you to create sprites using
load.image
during development, and then change them
to use a Texture Atlas later in development by simply searching your code for 'PENDING_ATLAS'
and swapping it to be the key of the atlas data.Note: You cannot use a RenderTexture as a texture for a TileSprite.
Parameters:
Name Type Argument Default Description key
string | Phaser.RenderTexture | Phaser.BitmapData | Phaser.Video | PIXI.Texture This is the image or texture used by the Sprite during rendering. It can be a string which is a reference to the Cache Image entry, or an instance of a RenderTexture, BitmapData, Video or PIXI.Texture.
frame
string | number <optional>
If this Sprite is using part of a sprite sheet or texture atlas you can specify the exact frame to use by giving a string or numeric index.
stopAnimation
boolean <optional>
true If an animation is already playing on this Sprite you can choose to stop it or let it carry on playing.

moveDown() → {PIXI.DisplayObject}
-
Moves this Game Object down one place in its parents display list.
This call has no effect if the Game Object is already at the bottom of the display list.If this Game Object hasn't been added to a custom Group then this method will move it one object down within the Game World,
because the World is the root Group from which all Game Objects descend.Returns:

-
overlap(displayObject) → {boolean}
-
Checks to see if the bounds of this Game Object overlaps with the bounds of the given Display Object,
which can be a Sprite, Image, TileSprite or anything that extends those such as Button or provides agetBounds
method and result.This check ignores the
hitArea
property if set and runs agetBounds
comparison on both objects to determine the result.Therefore it's relatively expensive to use in large quantities, i.e. with lots of Sprites at a high frequency.
It should be fine for low-volume testing where physics isn't required.Parameters:
Name Type Description displayObject
Phaser.Sprite | Phaser.Image | Phaser.TileSprite | Phaser.Button | PIXI.DisplayObject The display object to check against.
Returns:
boolean -True if the bounds of this Game Object intersects at any point with the bounds of the given display object.

play(name, frameRate, loop, killOnComplete) → {Phaser.Animation}
-
Plays an Animation.
The animation should have previously been created via
animations.add
.If the animation is already playing calling this again won't do anything.
If you need to reset an already running animation do so directly on the Animation object itself or viaAnimationManager.stop
.Parameters:
Name Type Argument Default Description name
string The name of the animation to be played, e.g. "fire", "walk", "jump". Must have been previously created via 'AnimationManager.add'.
frameRate
number <optional>
null The framerate to play the animation at. The speed is given in frames per second. If not provided the previously set frameRate of the Animation is used.

-
setScaleMinMax(minX, minY, maxX, maxY)
-
Sets the scaleMin and scaleMax values. These values are used to limit how far this Game Object will scale based on its parent.
For example if this Game Object has a
minScale
value of 1 and its parent has ascale
value of 0.5, the 0.5 will be ignored
and the scale value of 1 will be used, as the parents scale is lower than the minimum scale this Game Object should adhere to.By setting these values you can carefully control how Game Objects deal with responsive scaling.
If only one parameter is given then that value will be used for both scaleMin and scaleMax:
setScaleMinMax(1)
= scaleMin.x, scaleMin.y, scaleMax.x and scaleMax.y all = 1If only two parameters are given the first is set as scaleMin.x and y and the second as scaleMax.x and y:
setScaleMinMax(0.5, 2)
= scaleMin.x and y = 0.5 and scaleMax.x and y = 2If you wish to set
scaleMin
with different values for x and y then either modify Game Object.scaleMin directly,
or passnull
for themaxX
andmaxY
parameters.Call
setScaleMinMax(null)
to clear all previously set values.Parameters:
Name Type Description minX
number | null The minimum horizontal scale value this Game Object can scale down to.
minY
number | null The minimum vertical scale value this Game Object can scale down to.
maxX
