Phaser API

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:

x number <optional>
 0

X position of the Button.
y number <optional>
 0

Y position of the Button.
key string <optional>

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 65

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 168
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:
Default Value:
  • false
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.

Inherited From:
Default Value:
  • PIXI.blendModes.NORMAL;
Source - pixi/display/Sprite.js, line 68

<readonly> 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 110

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 336

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 58

<readonly> children :Array.<DisplayObject>

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

Type:
Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 17

<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 144

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:
Default Value:
  • null
Source - gameobjects/components/Crop.js, line 24

debug :boolean

A debug flag designed for use with Game.enableStep.

Inherited From:
Default Value:
  • false
Source - gameobjects/components/Core.js, line 193

<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 160
See:

exists :boolean

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

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

Inherited From:
Source - gameobjects/components/Core.js, line 248

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 153

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'

Type:
  • Array.<Filter>
Inherited From:
Source - pixi/display/DisplayObject.js, line 298

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 50

forceOut :boolean

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

Default Value:
  • false
Source - gameobjects/Button.js, line 194

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 196

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 221

freezeFrames :boolean

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

Default Value:
  • false
Source - gameobjects/Button.js, line 187

<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 223

game :Phaser.Game

A reference to the currently running Game.

Inherited From:
Source - gameobjects/components/Core.js, line 129

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 118

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 81

<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

key :string|Phaser.RenderTexture|Phaser.BitmapData|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.Cache. It can also be an instance of a RenderTexture, BitmapData 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 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 178

<readonly> left :number

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

Inherited From:
Source - gameobjects/components/Bounds.js, line 59

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:
Default Value:
  • 0
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 273

name :string

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

Inherited From:
Source - gameobjects/components/Core.js, line 137

<readonly> offsetX :number

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

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

<readonly> offsetY :number

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

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)

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.

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

Should every child of this object have its destroy method called as well?
Inherited From:
Source - gameobjects/components/Destroy.js, line 33

destroy()

Destroy this DisplayObject. Removes all references to transformCallbacks, its parent, the stage, filters, bounds, mask and cached Sprites.

Inherited From:
Source - pixi/display/DisplayObject.js, line 212

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

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.

Returns:
Rectangle -

The rectangular bounding area

Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 364

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.

Parameters:
Name Type Argument Default Description
key string | Phaser.RenderTexture | Phaser.BitmapData | 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 entry, or an instance of a RenderTexture, BitmapData 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

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.

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.

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.
loop boolean <optional>
 false

Should the animation be looped after playback. If not provided the previously set loop value of the Animation is used.
killOnComplete boolean <optional>
 false

If set to true when the animation completes (only happens if loop=false) the parent Sprite will be killed.
