Class: Button

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:

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.

Type:
  • boolean

Default Value:
  • true
Source:
src/gameobjects/components/LifeSpan.js line 56

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.

Type:

anchor : Point

The anchor sets the origin point of the texture. The default (0, 0) is the top left. (0.5, 0.5) is the center. (1, 1) is the bottom right.

You can modify the default values in PIXI.Sprite.defaultAnchor.

Type:
  • Point
Inherited From:
Source:
src/pixi/display/Sprite.js line 28

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.

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.

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.

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.

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.

Transparent areas adjoining the edges may be removed (#283).

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. Cache this DisplayObject as a Bitmap. Set to null to remove an existing cached bitmap.

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.

fixedToCamera : boolean

A Game Object that is "fixed" to the camera is rendered at a given x/y offsets from the top left of the camera. The offsets are stored in the cameraOffset property, which is initialized with the current object coordinates.

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.

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.

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.

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.

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:
src/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.

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.

alignIn(container [, position] [, offsetX] [, offsetY])

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.

alignTo(parent [, position] [, offsetX] [, offsetY])

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.

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>

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:

Removes any cached sprites, sets renderable flag to false, and nulls filters, bounds and mask.

Also iteratively calls destroy on any children.

Inherited From:

generateTexture( [resolution] [, scaleMode], renderer)

Generates a RenderTexture based on this DisplayObject, which can they be used to texture other Sprites. This can be useful if your DisplayObject is static, or complicated, and needs to be reused multiple times.

Please note that no garbage collection takes place on old textures. It is up to you to destroy old textures, and references to them, so they don't linger in memory.

Parameters:
Name Type Argument Default Description
resolution number <optional>
1

The resolution of the texture being generated.

scaleMode number <optional>
PIXI.scaleModes.DEFAULT

See {{#crossLink "PIXI/scaleModes:property"}}PIXI.scaleModes{{/crossLink}} for possible values.

renderer PIXI.CanvasRenderer | PIXI.WebGLRenderer

Returns:
  • A RenderTexture containing an image of this DisplayObject at the time it was invoked.
Type

getBounds(matrix)

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:

kill()

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.

Type
PIXI.DisplayObject

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)

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

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.

update()

Override this method in your own custom objects to handle any update requirements. It is called immediately after preUpdate and before postUpdate. Remember if this Game Object has any children you should call update on those too.

Returns:
  • A reference to this DisplayObject.

updateCrop()

If you have set a crop rectangle on this Game Object via crop and since modified the cropRect property, or the rectangle it references, then you need to update the crop frame by calling this method.

Inherited From:
Source:
src/gameobjects/components/Crop.js line 86

updateTransform( [parent])

Updates the transform matrix this DisplayObject uses for rendering.

If the object has no parent, and no parent parameter is provided, it will default to Phaser.Game.World as the parent transform to use. If that is unavailable the transform fails to take place.

The parent parameter has priority over the actual parent. Use it as a parent override. Setting it does not change the actual parent of this DisplayObject.

Calling this method updates the worldTransform, worldAlpha, worldPosition, worldScale and worldRotation properties.

If a transformCallback has been specified, it is called at the end of this method, and is passed the new, updated, worldTransform property, along with the parent transform used.

Parameters:
Name Type Argument Description
parent PIXI.DisplayObjectContainer <optional>

Optional parent to calculate this DisplayObjects transform from.

Inherited From:
Source:
src/pixi/display/DisplayObject.js line 289
Returns:
  • A reference to this DisplayObject.
Type
PIXI.DisplayObject
