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 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 alpha value of this DisplayObject. A value of 1 is fully opaque. A value of 0 is transparent.
Please note that an object with an alpha value of 0 is skipped during the render pass.

The value of this property does not reflect any alpha values set further up the display list.
To obtain that value please see the worldAlpha property.

Inherited From:
Source - pixi/display/DisplayObject.js, line 63

<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
See:

<internal> autoAlpha :boolean

If this Particle automatically changes alpha this is set to true by Particle.setAlphaData.

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 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 - gameobjects/components/AutoCull.js, line 28

<internal> autoScale :boolean

If this Particle automatically scales this is set to true by Particle.setScaleData.

Internal:
  • This member is internal (protected) and may be modified or removed in the future.
Source - gameobjects/Particle.js, line 27

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 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 - 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 - gameobjects/components/Bounds.js, line 168

cacheAsBitmap :Boolean

Sets if this DisplayObject should be cached as a bitmap.

When invoked it will take a snapshot of the DisplayObject, as it is at that moment, and store it
in a RenderTexture. This is then used whenever this DisplayObject is rendered. It can provide a
performance benefit for complex, but static, DisplayObjects. I.e. those with lots of children.

Cached Bitmaps do not track their parents. If you update a property of this DisplayObject, it will not
re-generate the cached bitmap automatically. To do that you need to call DisplayObject.updateCache.

To remove a cached bitmap, set this property to null.

Inherited From:
Source - pixi/display/DisplayObject.js, line 763

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

centerX :number

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

Inherited From:
Source - 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 - 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.

Inherited From:
Source - gameobjects/components/InWorld.js, line 98

<readonly> children :Array.<DisplayObject>

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

  • This member is internal (protected) and may be modified or removed in the future.
Source - gameobjects/components/Core.js, line 167

cropRect :Phaser.Rectangle

The Rectangle used to crop the texture this Game Object uses.
Set this property via crop.
If you modify this property directly you must call updateCrop in order to have the change take effect.

Inherited From:
Source - gameobjects/components/Crop.js, line 24

damage

Damages the Game Object. This removes the given amount of health from the health property.

If health is taken below or is equal to zero then the kill method is called.

Inherited From:
Source - gameobjects/components/Health.js, line 46

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.

Inherited From:
Default Value:
  • {}
Source - gameobjects/components/Core.js, line 160

debug :boolean

A debug flag designed for use with Game.enableStep.

Inherited From:
Source - gameobjects/components/Core.js, line 218

<readonly> deltaX :number

Returns the delta x value. The difference between world.x now and in the previous frame.

The value will be positive if the Game Object has moved to the right or negative if to the left.

Inherited From:
Source - gameobjects/components/Delta.js, line 24

<readonly> deltaY :number

Returns the delta y value. The difference between world.y now and in the previous frame.

The value will be positive if the Game Object has moved down or negative if up.

Inherited From:

<readonly> deltaZ :number

Returns the delta z value. The difference between rotation now and in the previous frame. The delta value.

Inherited From:
Source - gameobjects/components/Delta.js, line 58

<readonly> destroyPhase :boolean

As a Game Object runs through its destroy method this flag is set to true,
and can be checked in any sub-systems or plugins it is being destroyed from.

Inherited From:
Source - gameobjects/components/Destroy.js, line 22

events :Phaser.Events

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 - gameobjects/components/Core.js, line 185
See:

exists :Boolean

Controls if this Sprite is processed by the core Phaser game loops and Group loops.

Inherited From:
Default Value:
  • true
Source - pixi/display/Sprite.js, line 103

filterArea :Rectangle

The rectangular area used by filters when rendering a shader for this DisplayObject.

Inherited From:
Source - pixi/display/DisplayObject.js, line 195

filters :Array

Sets the filters for this DisplayObject. This is a WebGL only feature, and is ignored by the Canvas
Renderer. A filter is a shader applied to this DisplayObject. You can modify the placement of the filter
using DisplayObject.filterArea.

To remove filters, set this property to null.

Note: You cannot have a filter set, and a MULTIPLY Blend Mode active, at the same time. Setting a
filter will reset this DisplayObjects blend mode to NORMAL.

Inherited From:
Source - pixi/display/DisplayObject.js, line 710

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 - 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

<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 - gameobjects/components/Core.js, line 248

game :Phaser.Game

A reference to the currently running Game.

Inherited From:
Source - gameobjects/components/Core.js, line 142

heal

Heal the Game Object. This adds the given amount of health to the health property.

Inherited From:
Source - gameobjects/components/Health.js, line 90

health :number

The Game Objects health value. This is a handy property for setting and manipulating health on a Game Object.

It can be used in combination with the damage method or modified directly.

Inherited From:
Default Value:
  • 1
Source - gameobjects/components/Health.js, line 26

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

hitArea :Rectangle|Circle|Ellipse|Polygon

This is the defined area that will pick up mouse / touch events. It is null by default.
Setting it is a neat way of optimising the hitTest function that the interactionManager will use (as it will not need to hit test all the children)

Type:
  • Rectangle | Circle | Ellipse | Polygon
Inherited From:
Source - pixi/display/DisplayObject.js, line 89

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 - 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 - 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 - 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 - 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 - 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.

Type:
Inherited From:
Source - gameobjects/components/Core.js, line 203

left :number

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

Inherited From:
Source - 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 - gameobjects/components/LifeSpan.js, line 65

mask :PIXIGraphics

Sets a mask for this DisplayObject. A mask is an instance of a Graphics object.
When applied it limits the visible area of this DisplayObject to the shape of the mask.
Under a Canvas renderer it uses shape clipping. Under a WebGL renderer it uses a Stencil Buffer.
To remove a mask, set this property to null.

Inherited From:
Source - pixi/display/DisplayObject.js, line 675

maxHealth :number

The Game Objects maximum health value. This works in combination with the heal method to ensure
the health value never exceeds the maximum.

Inherited From:
Default Value:
  • 100
Source - gameobjects/components/Health.js, line 35

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.

Source - gameobjects/components/Bounds.js, line 223

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.
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 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.

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 PIXI.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 modifying cropRect property directly and then calling updateCrop.

The rectangle object given to this method can be either a Phaser.Rectangle or any other object
so long as it has public x, y, width, height, right and bottom properties.

A reference to the rectangle is stored in cropRect unless the copy parameter is true,
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 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.
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 call updateTransform
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

Source - pixi/display/Sprite.js, line 199

getChildAt(index) → {PIXI.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 PIXI.DisplayObject

Returns:
Number -

The index position of the child display object to identify

Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 112

getLocalBounds() → {Rectangle}

Retrieves the non-global local bounds of the Sprite as a rectangle. The calculation takes all visible children into consideration.

Returns:
Rectangle -

The rectangular bounding area

Inherited From:
Source - pixi/display/Sprite.js, line 315

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.

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 or frameName 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 the frame 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.

Source - gameobjects/components/LoadTexture.js, line 51

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:
PIXI.DisplayObject -

This instance.

Inherited From:
Source - gameobjects/components/BringToTop.js, line 87

moveUp() → {PIXI.DisplayObject}

Moves this Game Object up one place in its parents display list.
This call has no effect if the Game Object is already at the top of the display list.

If this Game Object hasn't been added to a custom Group then this method will move it one object up within the Game World,
because the World is the root Group from which all Game Objects descend.

Returns:
PIXI.DisplayObject -

onEmit()

Called by the Emitter when this particle is emitted. Left empty for you to over-ride as required.

Source - gameobjects/Particle.js, line 102

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 a getBounds method and result.

This check ignores the hitArea property if set and runs a getBounds 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.

Inherited From:
Source - gameobjects/components/Overlap.js, line 29

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 via AnimationManager.stop.

setFrame(frame)

Sets the texture frame the Game Object uses for rendering.

This is primarily an internal method used by loadTexture, but is exposed for the use of plugins and custom classes.

Parameters:

setScaleData()

Called by the Emitter if autoScale has been enabled. Passes over the scale ease data and resets the scale counter.

Source - gameobjects/Particle.js, line 126

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 a scale 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 = 1

If 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 = 2

If you wish to set scaleMin with different values for x and y then either modify Game Object.scaleMin directly,
or pass null for the maxX and maxY 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 number | null

The maximum horizontal scale value this Game Object can scale up to.
maxY number | null

The maximum vertical scale value this Game Object can scale up to.
