A Container Game Object.
A Container, as the name implies, can 'contain' other types of Game Object. When a Game Object is added to a Container, the Container becomes responsible for the rendering of it. By default it will be removed from the Display List and instead added to the Containers own internal list.
The position of the Game Object automatically becomes relative to the position of the Container.
The transform point of a Container is 0x0 (in local space) and that cannot be changed. The children you add to the Container should be positioned with this value in mind. I.e. you should treat 0x0 as being the center of the Container, and position children positively and negative around it as required.
When the Container is rendered, all of its children are rendered as well, in the order in which they exist
within the Container. Container children can be repositioned using methods such as MoveUp, MoveDown and SendToBack.
If you modify a transform property of the Container, such as Container.x or Container.rotation then it will
automatically influence all children as well.
Containers can include other Containers for deeply nested transforms.
Containers can have masks set on them and can be used as a mask too. However, Container children cannot be masked. The masks do not 'stack up'. Only a Container on the root of the display list will use its mask.
Containers can be enabled for input. Because they do not have a texture you need to provide a shape for them to use as their hit area. Container children can also be enabled for input, independent of the Container.
If input enabling a child you should not set both the origin and a negative scale factor on the child,
or the input area will become misaligned.
Containers can be given a physics body for either Arcade Physics, Impact Physics or Matter Physics. However, if Container children are enabled for physics you may get unexpected results, such as offset bodies, if the Container itself, or any of its ancestors, is positioned anywhere other than at 0 x 0. Container children with physics do not factor in the Container due to the excessive extra calculations needed. Please structure your game to work around this.
It's important to understand the impact of using Containers. They add additional processing overhead into every one of their children. The deeper you nest them, the more the cost escalates. This is especially true for input events. You also loose the ability to set the display depth of Container children in the same flexible manner as those not within them. In short, don't use them for the sake of it. You pay a small cost every time you create one, try to structure your game around avoiding that where possible.

Description:
The active state of this Game Object.
A Game Object with an active state of true is processed by the Scenes UpdateList, if added to it.
An active object is one which is having its logic and internal systems updated.
Type:
Description:
The alpha value of the Game Object.
This is a global value, impacting the entire Game Object, not just a region of it.
Type:
Description:
The angle of this Game Object as expressed in degrees.
Phaser uses a right-hand clockwise rotation system, where 0 is right, 90 is down, 180/-180 is left and -90 is up.
If you prefer to work in radians, see the rotation property instead.
Type:
Description:
Sets the Blend Mode being used by this Game Object.
This can be a const, such as Phaser.BlendModes.SCREEN, or an integer, such as 4 (for Overlay)
Under WebGL only the following Blend Modes are available:
- NORMAL
- ADD
- MULTIPLY
- SCREEN
- ERASE
Canvas has more available depending on browser support.
You can also create your own custom Blend Modes in WebGL.
Blend modes have different effects under Canvas and WebGL, and from browser to browser, depending on support. Blend Modes also cause a WebGL batch flush should it encounter a new blend mode. For these reasons try to be careful about the construction of your Scene and the frequency of which blend modes are used.
Type:
Description:
If this Game Object is enabled for Arcade or Matter Physics then this property will contain a reference to a Physics Body.
Type:
Description:
A bitmask that controls if this Game Object is drawn by a Camera or not.
Not usually set directly, instead call Camera.ignore, however you can
set this property directly using the Camera.id property:
Type:
Description:
A Data Manager.
It allows you to store, query and get key/value paired information specific to this Game Object.
null by default. Automatically created if you use getData or setData or setDataEnabled.
Type:
Description:
The depth of this Game Object within the Scene. Ensure this value is only ever set to a number data-type.
The depth is also known as the 'z-index' in some environments, and allows you to change the rendering order of Game Objects, without actually moving their position in the display list.
The default depth is zero. A Game Object with a higher depth value will always render in front of one with a lower value.
Setting the depth will queue a depth sort event within the Scene.
Type:
Description:
The displayed height of this Game Object.
This value takes into account the scale factor.
Setting this value will adjust the Game Object's scale property.
Type:
Description:
Holds a reference to the Display List that contains this Game Object.
This is set automatically when this Game Object is added to a Scene or Layer.
You should treat this property as being read-only.
Description:
Internal value to allow Containers to be used for input and physics. Do not change this value. It has no effect other than to break things.

Type:
Description:
The displayed width of this Game Object.
This value takes into account the scale factor.
Setting this value will adjust the Game Object's scale property.
Type:
Description:
Does this Container exclusively manage its children?
The default is true which means a child added to this Container cannot
belong in another Container, which includes the Scene display list.
If you disable this then this Container will no longer exclusively manage its children. This allows you to create all kinds of interesting graphical effects, such as replicating Game Objects without reparenting them all over the Scene. However, doing so will prevent children from receiving any kind of input event or have their physics bodies work by default, as they're no longer a single entity on the display list, but are being replicated where-ever this Container is.
Type:
Description:
Returns the first Game Object within the Container, or null if it is empty.
You can move the cursor by calling Container.next and Container.previous.
Description:
Does this Game Object have any Post Pipelines set?
Type:
Description:
A property indicating that a Game Object has this component.
Type:
Description:
The native (un-scaled) height of this Game Object.
Changing this value will not change the size that the Game Object is rendered in-game.
For that you need to either set the scale of the Game Object (setScale) or use
the displayHeight property.
Type:
Description:
This Game Object will ignore all calls made to its destroy method if this flag is set to true.
This includes calls that may come from a Group, Container or the Scene itself.
While it allows you to persist a Game Object across Scenes, please understand you are entirely
responsible for managing references to and from this Game Object.
Type:
Description:
If this Game Object is enabled for input then this property will contain an InteractiveObject instance.

This property is always null until the initPostPipeline method is called.
Description:
An object to store pipeline specific data in, to be read by the pipelines this Game Object uses.
Type:
Description:
The WebGL Post FX Pipelines this Game Object uses for post-render effects.
The pipelines are processed in the order in which they appear in this array.
If you modify this array directly, be sure to set the
hasPostPipeline property accordingly.
Type:
Description:
The Pre FX component of this Game Object.
This component allows you to apply a variety of built-in effects to this Game Object, such as glow, blur, bloom, displacements, vignettes and more. You access them via this property, for example:
const player = this.add.sprite();

Description:
Returns the previous Game Object within the Container, or null if it is empty.
You can move the cursor by calling Container.next and Container.previous.
Description:
The flags that are compared against RENDER_MASK to determine if this Game Object will render or not.
The bits are 0001 | 0010 | 0100 | 1000 set by the components Visible, Alpha, Transform and Texture respectively.
If those components are not used by your custom class then you can use this bitmask as you wish.
Type:
Description:
The angle of this Game Object in radians.
Phaser uses a right-hand clockwise rotation system, where 0 is right, PI/2 is down, +-PI is left and -PI/2 is up.
If you prefer to work in degrees, see the angle property instead.
Type:
Description:
This is a special setter that allows you to set both the horizontal and vertical scale of this Game Object
to the same value, at the same time. When reading this value the result returned is (scaleX + scaleY) / 2.
Use of this property implies you wish the horizontal and vertical scales to be equal to each other. If this
isn't the case, use the scaleX or scaleY properties instead.
Type:
Description:
The horizontal scale of this Game Object.
Type:
Description:
The vertical scale of this Game Object.
Type:
Description:
A reference to the Scene to which this Game Object belongs.
Game Objects can only belong to one Scene.
You should consider this property as being read-only. You cannot move a Game Object to another Scene by simply changing it.
Type:
Description:
The horizontal scroll factor of this Container.
The scroll factor controls the influence of the movement of a Camera upon this Container.
When a camera scrolls it will change the location at which this Container is rendered on-screen. It does not change the Containers actual position values.
For a Container, setting this value will only update the Container itself, not its children.
If you wish to change the scrollFactor of the children as well, use the setScrollFactor method.
A value of 1 means it will move exactly in sync with a camera. A value of 0 means it will not move at all, even if the camera moves. Other values control the degree to which the camera movement is mapped to this Container.
Please be aware that scroll factor values other than 1 are not taken in to consideration when calculating physics collisions. Bodies always collide based on their world position, but changing the scroll factor is a visual adjustment to where the textures are rendered, which can offset them from physics bodies if not accounted for in your code.
Type:
Description:
The vertical scroll factor of this Container.
The scroll factor controls the influence of the movement of a Camera upon this Container.
When a camera scrolls it will change the location at which this Container is rendered on-screen. It does not change the Containers actual position values.
For a Container, setting this value will only update the Container itself, not its children.
If you wish to change the scrollFactor of the children as well, use the setScrollFactor method.
A value of 1 means it will move exactly in sync with a camera. A value of 0 means it will not move at all, even if the camera moves. Other values control the degree to which the camera movement is mapped to this Container.
Please be aware that scroll factor values other than 1 are not taken in to consideration when calculating physics collisions. Bodies always collide based on their world position, but changing the scroll factor is a visual adjustment to where the textures are rendered, which can offset them from physics bodies if not accounted for in your code.
Type:
Description:
The current state of this Game Object.
Phaser itself will never modify this value, although plugins may do so.
Use this property to track the state of a Game Object during its lifetime. For example, it could change from a state of 'moving', to 'attacking', to 'dead'. The state value should be an integer (ideally mapped to a constant in your game code), or a string. These are recommended to keep it light and simple, with fast comparisons. If you need to store complex data about your Game Object, look at using the Data Component instead.
Type:
Description:
The Tab Index of the Game Object. Reserved for future use by plugins and the Input Manager.
Type:
Description:
A textual representation of this Game Object, i.e. sprite.
Used internally by Phaser but is available for your own custom classes to populate.
Type:
Description:
The visible state of the Game Object.
An invisible Game Object will skip rendering, but will still process update logic.
Type:
Description:
The w position of this Game Object.
Type:
Description:
The native (un-scaled) width of this Game Object.
Changing this value will not change the size that the Game Object is rendered in-game.
For that you need to either set the scale of the Game Object (setScale) or use
the displayWidth property.
Type:
Description:
The x position of this Game Object.
Type:
Description:
The y position of this Game Object.
Type:
Description:
The z position of this Game Object.
Note: The z position does not control the rendering order of 2D Game Objects. Use Phaser.GameObjects.Components.Depth#depth instead.

When a Game Object is added to the Update List it will have its preUpdate method called
every game frame. This method is passed two parameters: delta and time.
If you wish to run your own logic within preUpdate then you should always call
super.preUpdate(delta, time) within it, or it may fail to process required operations,
such as Sprite animations.
Returns:
Description:

Description:
Creates and returns a Bitmap Mask. This mask can be used by any Game Object, including this one, or a Dynamic Texture.
Note: Bitmap Masks only work on WebGL. Geometry Masks work on both WebGL and Canvas.
To create the mask you need to pass in a reference to a renderable Game Object. A renderable Game Object is one that uses a texture to render with, such as an Image, Sprite, Render Texture or BitmapText.
If you do not provide a renderable object, and this Game Object has a texture, it will use itself as the object. This means you can call this method to create a Bitmap Mask from any renderable texture-based Game Object.
Parameters:
| name | type | arguments | description |
|---|---|---|---|
| maskObject | Phaser.GameObjects.GameObject | Phaser.Textures.DynamicTexture | <optional> |
The Game Object or Dynamic Texture that will be used as the mask. If |
| x | number | <optional> |
If creating a Game Object, the horizontal position in the world. |
| y | number | <optional> |
If creating a Game Object, the vertical position in the world. |
| texture | string | Phaser.Textures.Texture | <optional> |
If creating a Game Object, the key, or instance of the Texture it will use to render with, as stored in the Texture Manager. |
| frame | string | number | Phaser.Textures.Frame | <optional> |
If creating a Game Object, an optional frame from the Texture this Game Object is rendering with. |
Returns:
Description:
This Bitmap Mask that was created.
Description:
Creates and returns a Geometry Mask. This mask can be used by any Game Object, including this one.
To create the mask you need to pass in a reference to a Graphics Game Object.
If you do not provide a graphics object, and this Game Object is an instance of a Graphics object, then it will use itself to create the mask.
This means you can call this method to create a Geometry Mask from any Graphics Game Object.
Parameters:
| name | type | arguments | description |
|---|---|---|---|
| graphics | Phaser.GameObjects.Graphics | Phaser.GameObjects.Shape | <optional> |
A Graphics Game Object, or any kind of Shape Game Object. The geometry within it will be used as the mask. |
Returns:
Description:
This Geometry Mask that was created.
Description:
Destroys this Game Object removing it from the Display List and Update List and severing all ties to parent resources.
Also removes itself from the Input Manager and Physics Manager if previously enabled.
Use this to remove a Game Object from your game if you don't ever plan to use it again. As long as no reference to it exists within your own code it should become free for garbage collection by the browser.
If you just want to temporarily disable an object then look at using the Game Object Pool instead of destroying it, as destroyed objects cannot be resurrected.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| fromScene | boolean | <optional> | false |
|
Description:
If this Game Object has previously been enabled for input, this will disable it.
An object that is disabled for input stops processing or being considered for
input events, but can be turned back on again at any time by simply calling
setInteractive() with no arguments provided.
If want to completely remove interaction from this Game Object then use removeInteractive instead.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| resetCursor | boolean | <optional> | false |
Should the currently active Input cursor, if any, be reset to the default cursor? |
Returns:
Description:
This GameObject.
Description:
Passes all Game Objects in this Container to the given callback.
A copy of the Container is made before passing each entry to your callback. This protects against the callback itself modifying the Container.
If you know for sure that the callback will not change the size of this Container
then you can use the more performant Container.iterate method instead.
Parameters:
| name | type | arguments | description |
|---|---|---|---|
| callback | function |
The function to call. |
|
| context | object | <optional> |
Value to use as |
| args | * | <optional> |

Description:
Returns all Game Objects in this Container.
You can optionally specify a matching criteria using the property and value arguments.
For example: getAll('body') would return only Game Objects that have a body property.
You can also specify a value to compare the property to:
getAll('visible', true) would return only Game Objects that have their visible property set to true.
Optionally you can specify a start and end index. For example if this Container had 100 Game Objects,
and you set startIndex to 0 and endIndex to 50, it would return matches from only
the first 50 Game Objects.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| property | string | <optional> |
The property to test on each Game Object in the Container. |

The position to get the Game Object from. |
Returns:
Description:
The Game Object at the specified index, or null if none found.
Description:
Gets the bounds of this Container. It works by iterating all children of the Container, getting their respective bounds, and then working out a min-max rectangle from that. It does not factor in if the children render or not, all are included.
Some children are unable to return their bounds, such as Graphics objects, in which case they are skipped.
Depending on the quantity of children in this Container it could be a really expensive call, so cache it and only poll it as needed.
The values are stored and returned in a Rectangle object.
Parameters:
| name | type | arguments | description |
|---|---|---|---|
| output | Phaser.Geom.Rectangle | <optional> |
A Geom.Rectangle object to store the values in. If not provided a new Rectangle will be created. |
Returns:

Description:
Searches for the first instance of a child with its name property matching the given argument.
Should more than one child have the same name only the first is returned.
Parameters:
| name | type | description |
|---|---|---|
| name | string |
The name to search for. |
Returns:
Description:
The first child with a matching name, or null if none were found.
Description:
Retrieves the value for the given key in this Game Objects Data Manager, or undefined if it doesn't exist.
You can also access values via the values object. For example, if you had a key called gold you can do either:
sprite.getData('gold');
Or access the value directly:
sprite.data.values.gold;
You can also pass in an array of keys, in which case an array of values will be returned:
sprite.getData([ 'gold', 'armor', 'health' ]);
This approach is useful for destructuring arrays in ES6.
Parameters:
| name | type | description |
|---|---|---|
| key | string | Array.<string> |
The key of the value to retrieve, or an array of keys. |
Returns:
Description:
The value belonging to the given key, or an array of values, the order of which will match the input array.
Type:
- *
Description:
Returns a reference to the underlying display list array that contains this Game Object, which will be either the Scene's Display List or the internal list belonging to its parent Container, if it has one.
If this Game Object is not on a display list or in a container, it will return null.
You should be very careful with this method, and understand that it returns a direct reference to the internal array used by the Display List. Mutating this array directly can cause all kinds of subtle and difficult to debug issues in your game.
Returns:
Description:
The internal Display List array of Game Objects, or null.
Type:
- Array.<Phaser.GameObjects.GameObject>
Description:
Gets the first Game Object in this Container.
You can also specify a property and value to search for, in which case it will return the first Game Object in this Container with a matching property and / or value.

Description:
Removes this Game Object from the Display List it is currently on.
A Game Object can only exist on one Display List at any given time, but may move freely removed and added back at a later stage.
You can query which list it is on by looking at the Phaser.GameObjects.GameObject#displayList property.
If a Game Object isn't on any Display List, it will not be rendered. If you just wish to temporarly
disable it from rendering, consider using the setVisible method, instead.
Returns:
Description:
This Game Object.
Description:
Removes this Game Object from the Scene's Update List.
When a Game Object is on the Update List, it will have its preUpdate method called
every game frame. Calling this method will remove it from the list, preventing this.
Removing a Game Object from the Update List will stop most internal functions working. For example, removing a Sprite from the Update List will prevent it from being able to run animations.
Returns:
Description:
This Game Object.
Description:
If this Game Object has previously been enabled for input, this will queue it for removal, causing it to no longer be interactive. The removal happens on the next game step, it is not immediate.
The Interactive Object that was assigned to this Game Object will be destroyed, removed from the Input Manager and cleared from this Game Object.
If you wish to re-enable this Game Object at a later date you will need to
re-create its InteractiveObject by calling setInteractive again.
If you wish to only temporarily stop an object from receiving input then use
disableInteractive instead, as that toggles the interactive state, where-as
this erases it completely.
If you wish to resize a hit area, don't remove and then set it as being
interactive. Instead, access the hitarea object directly and resize the shape
being used. I.e.: sprite.input.hitArea.setSize(width, height) (assuming the
shape is a Rectangle, which it is by default.)
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| resetCursor | boolean | <optional> | false |
Should the currently active Input cursor, if any, be reset to the default cursor? |
Returns:
Description:

Description:
Sets the Blend Mode being used by this Game Object.
This can be a const, such as Phaser.BlendModes.SCREEN, or an integer, such as 4 (for Overlay)
Under WebGL only the following Blend Modes are available:
- NORMAL
- ADD
- MULTIPLY
- SCREEN
- ERASE (only works when rendering to a framebuffer, like a Render Texture)
Canvas has more available depending on browser support.
You can also create your own custom Blend Modes in WebGL.
Blend modes have different effects under Canvas and WebGL, and from browser to browser, depending on support. Blend Modes also cause a WebGL batch flush should it encounter a new blend mode. For these reasons try to be careful about the construction of your Scene and the frequency in which blend modes are used.
Parameters:
| name | type | description |
|---|---|---|
| value | string | number | Phaser.BlendModes |
The BlendMode value. Either a string, a CONST or a number. |
Returns:
Description:
This Game Object instance.
Description:
Allows you to store a key value pair within this Game Objects Data Manager.
If the Game Object has not been enabled for data (via setDataEnabled) then it will be enabled
before setting the value.
If the key doesn't already exist in the Data Manager then it is created.
sprite.setData('name', 'Red Gem Stone');
You can also pass in an object of key value pairs as the first argument:
sprite.setData({ name: 'Red Gem Stone', level: 2, owner: 'Link', gold: 50 });
To get a value back again you can call getData:
sprite.getData('gold');
Or you can access the value directly via the values property, where it works like any other variable:
sprite.data.values.gold += 50;
When the value is first set, a setdata event is emitted from this Game Object.
If the key already exists, a changedata event is emitted instead, along an event named after the key.
For example, if you updated an existing key called PlayerLives then it would emit the event changedata-PlayerLives.
These events will be emitted regardless if you use this method to set the value, or the direct values setter.
Please note that the data keys are case-sensitive and must be valid JavaScript Object property strings.
This means the keys gold and Gold are treated as two unique values within the Data Manager.
Parameters:
| name | type | arguments | description |
|---|---|---|---|
| key | string | object |
The key to set the value for. Or an object of key value pairs. If an object the |
|
| data | * | <optional> |
The value to set for the given key. If an object is provided as the key this argument is ignored. |
Returns:
Description:
This GameObject.
Description:
Adds a Data Manager component to this Game Object.
Returns:
Description:
This GameObject.
Description:
The depth of this Game Object within the Scene.
The depth is also known as the 'z-index' in some environments, and allows you to change the rendering order of Game Objects, without actually moving their position in the display list.
The default depth is zero. A Game Object with a higher depth value will always render in front of one with a lower value.
Setting the depth will queue a depth sort event within the Scene.
Parameters:
| name | type | description |
|---|---|---|
| value | number |
The depth of this Game Object. Ensure this value is only ever a number data-type. |
Returns:
Description:
This Game Object instance.
Description:
Sets the display size of this Game Object.
Calling this will adjust the scale.
Parameters:
| name | type | description |
|---|---|---|
| width | number |
The width of this Game Object. |
| height | number |
The height of this Game Object. |
Returns:
Description:
This Game Object instance.
Description:
Does this Container exclusively manage its children?
The default is true which means a child added to this Container cannot
belong in another Container, which includes the Scene display list.
If you disable this then this Container will no longer exclusively manage its children. This allows you to create all kinds of interesting graphical effects, such as replicating Game Objects without reparenting them all over the Scene. However, doing so will prevent children from receiving any kind of input event or have their physics bodies work by default, as they're no longer a single entity on the display list, but are being replicated where-ever this Container is.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| value | boolean | <optional> | true |
The exclusive state of this Container. |
Returns:
Description:
This Container.
Description:
Pass this Game Object to the Input Manager to enable it for Input.
Input works by using hit areas, these are nearly always geometric shapes, such as rectangles or circles, that act as the hit area for the Game Object. However, you can provide your own hit area shape and callback, should you wish to handle some more advanced input detection.
If no arguments are provided it will try and create a rectangle hit area based on the texture frame the Game Object is using. If this isn't a texture-bound object, such as a Graphics or BitmapText object, this will fail, and you'll need to provide a specific shape for it to use.
You can also provide an Input Configuration Object as the only argument to this method.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| hitArea | any | Phaser.Types.Input.InputConfiguration | <optional> |
Either an input configuration object, or a geometric shape that defines the hit area for the Game Object. If not given it will try to create a Rectangle based on the texture frame. |
|
| callback | Phaser.Types.Input.HitAreaCallback | <optional> |
The callback that determines if the pointer is within the Hit Area shape or not. If you provide a shape you must also provide a callback. |
|
| dropZone | boolean | <optional> | false |
Should this Game Object be treated as a drop zone target? |
Returns:
Description:
This GameObject.
sprite.setInteractive();
sprite.setInteractive(new Phaser.Geom.Circle(45, 46, 45), Phaser.Geom.Circle.Contains);
graphics.setInteractive(new Phaser.Geom.Rectangle(0, 0, 128, 128), Phaser.Geom.Rectangle.Contains);
Description:
Sets the mask that this Game Object will use to render with.
The mask must have been previously created and can be either a GeometryMask or a BitmapMask. Note: Bitmap Masks only work on WebGL. Geometry Masks work on both WebGL and Canvas.
If a mask is already set on this Game Object it will be immediately replaced.
Masks are positioned in global space and are not relative to the Game Object to which they are applied. The reason for this is that multiple Game Objects can all share the same mask.
Masks have no impact on physics or input detection. They are purely a rendering component that allows you to limit what is visible during the render pass.
Parameters:
| name | type | description |
|---|---|---|
| mask | Phaser.Display.Masks.BitmapMask | Phaser.Display.Masks.GeometryMask |
The mask this Game Object will use when rendering. |
Returns:
Description:
This Game Object instance.

Returns:
Description:
This Game Object instance.
Description:
Sets one, or more, Post Pipelines on this Game Object.
Post Pipelines are invoked after this Game Object has rendered to its target and are commonly used for post-fx.
The post pipelines are appended to the postPipelines array belonging to this
Game Object. When the renderer processes this Game Object, it iterates through the post
pipelines in the order in which they appear in the array. If you are stacking together
multiple effects, be aware that the order is important.
If you call this method multiple times, the new pipelines will be appended to any existing
post pipelines already set. Use the resetPostPipeline method to clear them first, if required.
You can optionally also set the postPipelineData property, if the parameter is given.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| pipelines | string | Array.<string> | function | Array.<function()> | Phaser.Renderer.WebGL.Pipelines.PostFXPipeline | Array.<Phaser.Renderer.WebGL.Pipelines.PostFXPipeline> |

Returns:
Description:
This Game Object instance.
Description:
Sets the scroll factor of this Container and optionally all of its children.
The scroll factor controls the influence of the movement of a Camera upon this Game Object.
When a camera scrolls it will change the location at which this Game Object is rendered on-screen. It does not change the Game Objects actual position values.
A value of 1 means it will move exactly in sync with a camera. A value of 0 means it will not move at all, even if the camera moves. Other values control the degree to which the camera movement is mapped to this Game Object.
Please be aware that scroll factor values other than 1 are not taken in to consideration when calculating physics collisions. Bodies always collide based on their world position, but changing the scroll factor is a visual adjustment to where the textures are rendered, which can offset them from physics bodies if not accounted for in your code.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| x | number |
The horizontal scroll factor of this Game Object. |
||
| y | number | <optional> | x |
The vertical scroll factor of this Game Object. If not set it will use the |
| updateChildren | boolean | <optional> | false |
Apply this scrollFactor to all Container children as well? |
Returns:
Description:
This Game Object instance.
Description:
Sets the internal size of this Game Object, as used for frame or physics body creation.
This will not change the size that the Game Object is rendered in-game.
For that you need to either set the scale of the Game Object (setScale) or call the
setDisplaySize method, which is the same thing as changing the scale but allows you
to do so by giving pixel values.
If you have enabled this Game Object for input, changing the size will not change the
size of the hit area. To do this you should adjust the input.hitArea object directly.
Parameters:
| name | type | description |
|---|---|---|
| width | number |
The width of this Game Object. |
| height | number |
The height of this Game Object. |
Returns:
Description:
This Game Object instance.
Description:
Sets the current state of this Game Object.
Phaser itself will never modify the State of a Game Object, although plugins may do so.
For example, a Game Object could change from a state of 'moving', to 'attacking', to 'dead'. The state value should typically be an integer (ideally mapped to a constant in your game code), but could also be a string. It is recommended to keep it light and simple. If you need to store complex data about your Game Object, look at using the Data Component instead.
Parameters:
| name | type | description |
|---|---|---|
| value | number | string |
The state of the Game Object. |
Returns:
Description:
This GameObject.
Description:
Sets this Game Object to the back of the display list, or the back of its parent container.
Being at the back means it will render below everything else.
This method does not change this Game Objects depth value, it simply alters its list position.
Returns:
Description:
This Game Object instance.
Description:
Sets this Game Object to be at the top of the display list, or the top of its parent container.
Being at the top means it will render on-top of everything else.
This method does not change this Game Objects depth value, it simply alters its list position.
Returns:
Description:
This Game Object instance.
Description:
Sets the visibility of this Game Object.
An invisible Game Object will skip rendering, but will still process update logic.
Parameters:
| name | type | description |
|---|---|---|
| value | boolean |
The visible state of the Game Object. |
