new SpriteBatch(game, parent [, name] [, addToStage])
The SpriteBatch class is a really fast version of the DisplayObjectContainer built purely for speed, so use when you need a lot of sprites or particles. It's worth mentioning that by default sprite batches are used through-out the renderer, so you only really need to use a SpriteBatch if you have over 1000 sprites that all share the same texture (or texture atlas). It's also useful if running in Canvas mode and you have a lot of un-rotated or un-scaled Sprites as it skips all of the Canvas setTransform calls, which helps performance, especially on mobile devices.
Please note that any Sprite that is part of a SpriteBatch will not have its bounds updated, so will fail checks such as outOfBounds.

-
angle : number
-
The angle of rotation of the group container, in degrees.
This adjusts the group itself by modifying its local rotation transform.
This has no impact on the rotation/angle properties of the children, but it will update their worldTransform and on-screen orientation and position.
Type:
- number
- Inherited From:

-
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 tonull
to remove an existing cached bitmap.Type:

Methods
-
add(child [, silent] [, index])
-
Adds an existing object as the top child in this group.
The child is automatically added to the top of the group, and is displayed above every previous child.
Or if the optional index is specified, the child is added at the location specified by the index value, this allows you to control child ordering.
If the child was already in this Group, it is simply returned, and nothing else happens to it.
If
Group.enableBody
is set, then a physics body will be created on the object, so long as one does not already exist.If
Group.inputEnableChildren
is set, then an Input Handler will be created on the object, so long as one does not already exist.Use create to create and add a new child.
Parameters:
Name Type Argument Default Description child
DisplayObject The display object to add as a child.
silent
boolean <optional>
false If true the child will not dispatch the

align(width, height, cellWidth, cellHeight [, position] [, offset])
-
This method iterates through all children in the Group (regardless if they are visible or exist) and then changes their position so they are arranged in a Grid formation. Children must have the
alignTo
method in order to be positioned by this call. All default Phaser Game Objects have this.The grid dimensions are determined by the first four arguments. The
width
andheight
arguments relate to the width and height of the grid respectively.For example if the Group had 100 children in it:
Group.align(10, 10, 32, 32)
This will align all of the children into a grid formation of 10x10, using 32 pixels per grid cell. If you want a wider grid, you could do:
Group.align(25, 4, 32, 32)
This will align the children into a grid of 25x4, again using 32 pixels per grid cell.
You can choose to set either the
width
orheight
value to -1. Doing so tells the method to keep on aligning children until there are no children left. For example if this Group had 48 children in it, the following:Group.align(-1, 8, 32, 32)
... will align the children so that there are 8 children vertically (the second argument), and each row will contain 6 sprites, except the last one, which will contain 5 (totaling 48)
You can also do:
Group.align(10, -1, 32, 32)
In this case it will create a grid 10 wide, and as tall as it needs to be in order to fit all of the children in.
The
position
property allows you to control where in each grid cell the child is positioned. This is a constant and can be one ofPhaser.TOP_LEFT
(default),Phaser.TOP_CENTER
,Phaser.TOP_RIGHT
,Phaser.LEFT_CENTER
,Phaser.CENTER
,Phaser.RIGHT_CENTER
,Phaser.BOTTOM_LEFT
,Phaser.BOTTOM_CENTER
orPhaser.BOTTOM_RIGHT
.The final argument;
offset
lets you start the alignment from a specific child index.Parameters:
Name Type Argument Default Description width
integer The width of the grid in items (not pixels). Set to -1 for a dynamic width. If -1 then you must set an explicit height value.
height
integer The height of the grid in items (not pixels). Set to -1 for a dynamic height. If -1 then you must set an explicit width value.
cellWidth
integer The width of each grid cell, in pixels.
cellHeight
integer The height of each grid cell, in pixels.

alignIn(container [, position] [, offsetX] [, offsetY])
-
Aligns this Group 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
orCamera.view
, for aligning Groups within the world and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText, TileSprites or Buttons.Please note that aligning a Group to another Game Object does not make it a child of the container. It simply modifies its position coordinates so it aligns with it.
The position constants you can use are:
Phaser.TOP_LEFT
,Phaser.TOP_CENTER
,Phaser.TOP_RIGHT
,Phaser.LEFT_CENTER
,Phaser.CENTER
,Phaser.RIGHT_CENTER
,Phaser.BOTTOM_LEFT
,Phaser.BOTTOM_CENTER
andPhaser.BOTTOM_RIGHT
.Groups are placed in such a way that their bounds align with the container, taking into consideration rotation and scale of its children. This allows you to neatly align Groups, irrespective of their position value.
The optional
offsetX
andoffsetY
arguments allow you to apply extra spacing to the final aligned position of the Group. For example:group.alignIn(background, Phaser.BOTTOM_RIGHT, -20, -20)
Would align the
group
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 Group to. Can also include properties such as
World.bounds
orCamera.view
.position
integer <optional>
The position constant. One of
Phaser.TOP_LEFT
(default),Phaser.TOP_CENTER
,Phaser.TOP_RIGHT
,Phaser.LEFT_CENTER
,Phaser.CENTER
,Phaser.RIGHT_CENTER
,Phaser.BOTTOM_LEFT
,Phaser.BOTTOM_CENTER
orPhaser.BOTTOM_RIGHT
.offsetX
integer <optional>
0 A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
offsetY
integer <optional>
0 A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.

-
alignTo(parent [, position] [, offsetX] [, offsetY])
-
Aligns this Group 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
orCamera.view
, for aligning Groups within the world and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText, TileSprites or Buttons.Please note that aligning a Group 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.LEFT_TOP
,Phaser.LEFT_CENTER
,Phaser.LEFT_BOTTOM
,Phaser.RIGHT_TOP
,Phaser.RIGHT_CENTER
,Phaser.RIGHT_BOTTOM
,Phaser.BOTTOM_LEFT
,Phaser.BOTTOM_CENTER
andPhaser.BOTTOM_RIGHT
.Groups are placed in such a way that their bounds align with the parent, taking into consideration rotation and scale of the children. This allows you to neatly align Groups, irrespective of their position value.
The optional
offsetX
andoffsetY
arguments allow you to apply extra spacing to the final aligned position of the Group. For example:group.alignTo(background, Phaser.BOTTOM_RIGHT, -20, -20)
Would align the
group
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

createMultiple(quantity, key [, frame] [, exists] [, callback] [, callbackContext])
-
Creates multiple Phaser.Sprite objects and adds them to the top of this Group.
This method is useful if you need to quickly generate a pool of sprites, such as bullets.
Use classType to change the type of object created.
You can provide an array as the
key
and / orframe
arguments. When you do this it will createquantity
Sprites for every key (and frame) in the arrays.For example:
createMultiple(25, ['ball', 'carrot'])
In the above code there are 2 keys (ball and carrot) which means that 50 sprites will be created in total, 25 of each. You can also have the
frame
as an array:createMultiple(5, 'bricks', [0, 1, 2, 3])
In the above there is one key (bricks), which is a sprite sheet. The frames array tells this method to use frames 0, 1, 2 and 3. So in total it will create 20 sprites, because the quantity was set to 5, so that is 5 brick sprites of frame 0, 5 brick sprites with frame 1, and so on.
If you set both the key and frame arguments to be arrays then understand it will create a total quantity of sprites equal to the size of both arrays times each other. I.e.:
createMultiple(20, ['diamonds', 'balls'], [0, 1, 2])
The above will create 20 'diamonds' of frame 0, 20 with frame 1 and 20 with frame 2. It will then create 20 'balls' of frame 0, 20 with frame 1 and 20 with frame 2. In total it will have created 120 sprites.
By default the Sprites will have their
exists
property set tofalse
, and they will be positioned at 0x0, relative to theGroup.x / y
values.If
Group.enableBody
is set, then a physics body will be created on the objects, so long as one does not already exist.If
Group.inputEnableChildren
is set, then an Input Handler will be created on the objects, so long as one does not already exist.Parameters:
Name Type Argument Default Description quantity
integer The number of Sprites to create.
key
string | array The Cache key of the image that the Sprites will use. Or an Array of keys. See the description for details on how the quantity applies when arrays are used.
frame
integer | string | array <optional>

exists
boolean <optional>
false The default exists state of the Sprite.

sort( [key] [, order])
-
Sort the children in the group according to a particular key and ordering.
Call this function to sort the group according to a particular key value and order.
For example to depth sort Sprites for Zelda-style game you might call
group.sort('y', Phaser.Group.SORT_ASCENDING)
at the bottom of yourState.update()
.Internally this uses a standard JavaScript Array sort, so everything that applies there also applies here, including alphabetical sorting, mixing strings and numbers, and Unicode sorting. See MDN for more details.
Parameters:
Name Type Argument Default Description key
string <optional>
'z' The name of the property to sort on. Defaults to the objects z-depth value.
order
integer <optional>
Phaser.Group.SORT_ASCENDING Order ascending (SORT_ASCENDING) or descending (SORT_DESCENDING).

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
andworldRotation
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.
