Phaser. Button

new Button(game, x, y, key, callback, callbackContext, overFrame, outFrame, downFrame, upFrame)

Create a new Button object. A Button is a special type of Sprite that is set-up to handle Pointer events automatically.

The four states a Button responds to are:

  • 'Over' - when the Pointer moves over the Button. This is also commonly known as 'hover'.
  • 'Out' - when the Pointer that was previously over the Button moves out of it.
  • 'Down' - when the Pointer is pressed down on the Button. I.e. touched on a touch enabled device or clicked with the mouse.
  • 'Up' - when the Pointer that was pressed down on the Button is released again.

A different texture/frame and activation sound can be specified for any of the states.

Frames can be specified as either an integer (the frame ID) or a string (the frame name); the same values that can be used with a Sprite constructor.

Parameters:

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 opacity of the object.

Inherited From:
Source - pixi/display/DisplayObject.js, line 46

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 22

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:

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

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 87

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

Set if this display object is 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 'null'

Inherited From:
Source - pixi/display/DisplayObject.js, line 355

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).

<internal> components :object

The components this Game Object has installed.

Inherited From:
Internal:
  • 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

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> 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 107

filterArea :Rectangle

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

Inherited From:
Source - pixi/display/DisplayObject.js, line 164

filters :Array.<Filter>

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'.

You cannot have a filter and a multiply blend mode active at the same time. Setting a filter will reset this objects blend mode to NORMAL.

Type:
  • Array.<Filter>
Inherited From:
Source - pixi/display/DisplayObject.js, line 307

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

forceOut :boolean|Phaser.PointerMode

When the Button is touched / clicked and then released you can force it to enter a state of "out" instead of "up".

This can also accept a pointer mode bitmask for more refined control.

Type:
Source - gameobjects/Button.js, line 199

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 254

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 279

freezeFrames :boolean

When true the the texture frame will not be automatically switched on up/down/over/out events.

Source - gameobjects/Button.js, line 189

<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

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 148

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 62

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.

Inherited From:
Source - gameobjects/components/InputEnabled.js, line 38

justReleasedPreventsOver :Phaser.PointerMode

Suppresse the over event if a pointer was just released and it matches the given pointer mode bitmask.

This behavior was introduced in Phaser 2.3.1; this property is a soft-revert of the change.

Source - gameobjects/Button.js, line 182

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 :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:
Source - pixi/display/DisplayObject.js, line 282

name :string

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.

Inherited From:
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

Returns:
Object -

This Game Object.

Inherited From:
Source - gameobjects/components/Bounds.js, line 321

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

clearFrames()

Clears all of the frames set on this Button.

Source - gameobjects/Button.js, line 233

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 - pixi/display/DisplayObject.js, line 223

generateTexture(resolution, scaleMode, renderer) → {PIXI.RenderTexture}

Useful function that returns a texture of the displayObject object that can then be used to create sprites This can be quite useful if your displayObject is static / complicated and needs to be reused multiple times.

Parameters:
Name Type Description
resolution Number

The resolution of the texture being generated
scaleMode Number

See {{#crossLink "PIXI/scaleModes:property"}}PIXI.scaleModes{{/crossLink}} for possible values
renderer PIXI.CanvasRenderer | PIXI.WebGLRenderer

Returns:
PIXI.RenderTexture -

a texture of the graphics object

Inherited From:
Source - pixi/display/DisplayObject.js, line 541

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

Inherited From:
Source - pixi/display/Sprite.js, line 203

getChildAt(index) → {PIXI.DisplayObject}

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.

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.
