<div class="description">
<p>This method iterates through all children in the Group (regardless if they are visible or exist)<br>and then changes their position so they are arranged in a Grid formation. Children must have<br>the <code>alignTo</code> method in order to be positioned by this call. All default Phaser Game Objects have<br>this.</p>
<p>The grid dimensions are determined by the first four arguments. The <code>width</code> and <code>height</code> arguments<br>relate to the width and height of the grid respectively.</p>
<p>For example if the Group had 100 children in it:</p>
<p><code>Group.align(10, 10, 32, 32)</code></p>
<p>This will align all of the children into a grid formation of 10x10, using 32 pixels per<br>grid cell. If you want a wider grid, you could do:</p>
<p><code>Group.align(25, 4, 32, 32)</code></p>
<p>This will align the children into a grid of 25x4, again using 32 pixels per grid cell.</p>
<p>You can choose to set <em>either</em> the <code>width</code> or <code>height</code> value to -1. Doing so tells the method<br>to keep on aligning children until there are no children left. For example if this Group had<br>48 children in it, the following:</p>
<p><code>Group.align(-1, 8, 32, 32)</code></p>
<p>... will align the children so that there are 8 children vertically (the second argument),<br>and each row will contain 6 sprites, except the last one, which will contain 5 (totaling 48)</p>
<p>You can also do:</p>
<p><code>Group.align(10, -1, 32, 32)</code></p>
<p>In this case it will create a grid 10 wide, and as tall as it needs to be in order to fit<br>all of the children in.</p>
<p>The <code>position</code> property allows you to control where in each grid cell the child is positioned.<br>This is a constant and can be one of <code>Phaser.TOP_LEFT</code> (default), <code>Phaser.TOP_CENTER</code>,<br><code>Phaser.TOP_RIGHT</code>, <code>Phaser.LEFT_CENTER</code>, <code>Phaser.CENTER</code>, <code>Phaser.RIGHT_CENTER</code>,<br><code>Phaser.BOTTOM_LEFT</code>, <code>Phaser.BOTTOM_CENTER</code> or <code>Phaser.BOTTOM_RIGHT</code>.</p>
<p>The final argument; <code>offset</code> lets you start the alignment from a specific child index.</p>

<p>Aligns this Group within another Game Object, or Rectangle, known as the<br>'container', to one of 9 possible positions.</p>
<p>The container must be a Game Object, or Phaser.Rectangle object. This can include properties<br>such as <code>World.bounds</code> or <code>Camera.view</code>, for aligning Groups within the world<br>and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText,<br>TileSprites or Buttons.</p>
<p>Please note that aligning a Group to another Game Object does <strong>not</strong> make it a child of<br>the container. It simply modifies its position coordinates so it aligns with it.</p>
<p>The position constants you can use are:</p>
<p><code>Phaser.TOP_LEFT</code>, <code>Phaser.TOP_CENTER</code>, <code>Phaser.TOP_RIGHT</code>, <code>Phaser.LEFT_CENTER</code>,<br><code>Phaser.CENTER</code>, <code>Phaser.RIGHT_CENTER</code>, <code>Phaser.BOTTOM_LEFT</code>,<br><code>Phaser.BOTTOM_CENTER</code> and <code>Phaser.BOTTOM_RIGHT</code>.</p>
<p>Groups are placed in such a way that their <em>bounds</em> align with the<br>container, taking into consideration rotation and scale of its children.<br>This allows you to neatly align Groups, irrespective of their position value.</p>
<p>The optional <code>offsetX</code> and <code>offsetY</code> arguments allow you to apply extra spacing to the final<br>aligned position of the Group. For example:</p>
<p><code>group.alignIn(background, Phaser.BOTTOM_RIGHT, -20, -20)</code></p>
<p>Would align the <code>group</code> to the bottom-right, but moved 20 pixels in from the corner.<br>Think of the offsets as applying an adjustment to the containers bounds before the alignment takes place.<br>So providing a negative offset will 'shrink' the container bounds by that amount, and providing a positive<br>one expands it.</p>

<p>The optional <code>offsetX</code> and <code>offsetY</code> arguments allow you to apply extra spacing to the final<br>aligned position of the Group. For example:</p>
<p><code>group.alignTo(background, Phaser.BOTTOM_RIGHT, -20, -20)</code></p>
<p>Would align the <code>group</code> to the bottom-right, but moved 20 pixels in from the corner.<br>Think of the offsets as applying an adjustment to the parents bounds before the alignment takes place.<br>So providing a negative offset will 'shrink' the parent bounds by that amount, and providing a positive<br>one expands it.</p>

<div class="description">
<p>Creates multiple Phaser.Sprite objects and adds them to the top of this Group.</p>
<p>This method is useful if you need to quickly generate a pool of sprites, such as bullets.</p>
<p>Use <a href="Phaser.Group.html#classType">classType</a> to change the type of object created.</p>
<p>You can provide an array as the <code>key</code> and / or <code>frame</code> arguments. When you do this<br>it will create <code>quantity</code> Sprites for every key (and frame) in the arrays.</p>
<p>For example:</p>
<p><code>createMultiple(25, ['ball', 'carrot'])</code></p>
<p>In the above code there are 2 keys (ball and carrot) which means that 50 sprites will be<br>created in total, 25 of each. You can also have the <code>frame</code> as an array:</p>
<p><code>createMultiple(5, 'bricks', [0, 1, 2, 3])</code></p>
<p>In the above there is one key (bricks), which is a sprite sheet. The frames array tells<br>this method to use frames 0, 1, 2 and 3. So in total it will create 20 sprites, because<br>the quantity was set to 5, so that is 5 brick sprites of frame 0, 5 brick sprites with<br>frame 1, and so on.</p>
<p>If you set both the key and frame arguments to be arrays then understand it will create<br>a total quantity of sprites equal to the size of both arrays times each other. I.e.:</p>
<p><code>createMultiple(20, ['diamonds', 'balls'], [0, 1, 2])</code></p>
<p>The above will create 20 'diamonds' of frame 0, 20 with frame 1 and 20 with frame 2.<br>It will then create 20 'balls' of frame 0, 20 with frame 1 and 20 with frame 2.<br>In total it will have created 120 sprites.</p>
<p>By default the Sprites will have their <code>exists</code> property set to <code>false</code>, and they will be<br>positioned at 0x0, relative to the <code>Group.x / y</code> values.</p>
<p>If <code>Group.enableBody</code> is set, then a physics body will be created on the objects, so long as one does not already exist.</p>
<p>If <code>Group.inputEnableChildren</code> is set, then an Input Handler will be created on the objects, so long as one does not already exist.</p>

<p>Additional arguments for the callback can be specified after the <code>checkExists</code> parameter. For example,</p>
<pre class="prettyprint source"><code>Group.forEach(awardBonusGold, this, true, 100, 500)</code></pre><p>would invoke <code>awardBonusGold</code> function with the parameters <code>(child, 100, 500)</code>.</p>

<p>This is handy for choosing a squad leader, etc.</p>
<p>You can use the optional argument <code>createIfNull</code> to create a new Game Object if no alive ones were found in this Group.</p>
<p>It works by calling <code>Group.create</code> passing it the parameters given to this method, and returning the new child.</p>
<p>If a child <em>was</em> found , <code>createIfNull</code> is <code>false</code> and you provided the additional arguments then the child<br>will be reset and/or have a new texture loaded on it. This is handled by <code>Group.resetChild</code>.</p>

<p>Quickly set the same property across all children of this group, and any child Groups, to a new value.</p>
<p>If this group contains other Groups then the same property is set across their children as well, iterating down until it reaches the bottom.<br>Unlike with <code>setAll</code> the property is NOT set on child Groups itself.</p>
<p>The operation parameter controls how the new value is assigned to the property, from simple replacement to addition and multiplication.</p>
