The Scene to which this Game Object belongs.
The configuration object this Shader will use. It can also be a key that corresponds to a shader in the shader cache, which will be used as fragmentKey in a new config object.
Optionalx: numberThe horizontal position of this Game Object in the world. Default 0.
Optionaly: numberThe vertical position of this Game Object in the world. Default 0.
Optionalwidth: numberThe width of the Game Object. Default 128.
Optionalheight: numberThe height of the Game Object. Default 128.
Optionaltextures: string[] | Textures.Texture[]The textures that the shader uses, if any. If you intend to define the textures later, use '__DEFAULT' as a placeholder, to avoid initialization errors.
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.
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.
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:
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.
If this Game Object is enabled for Arcade or Matter Physics then this property will contain a reference to a Physics Body.
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:
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.
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.
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.
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.
The horizontal display origin of this Game Object. The origin is a normalized value between 0 and 1. The displayOrigin is a pixel value, based on the size of the Game Object combined with the origin.
The vertical display origin of this Game Object. The origin is a normalized value between 0 and 1. The displayOrigin is a pixel value, based on the size of the Game Object combined with the origin.
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.
The drawing context containing the framebuffer and texture that the shader is rendered to. This is only set if the shader is rendering to a texture.
The Camera used for filters. You can use this to alter the perspective of filters. It is not necessary to use this camera for ordinary rendering.
This is only available if you use the enableFilters method.
ReadonlyfiltersGet the filters lists.
This is an object with internal and external properties.
Each list is a {@see Phaser.GameObjects.Components.FilterList} object.
This is only available if you use the enableFilters method.
Whether filterCamera should update every frame
to focus on the Game Object.
Disable this if you want to manually control the camera.
Whether the filters should focus on the context, rather than attempt to focus on the Game Object. This is enabled automatically when enabling filters on objects which don't have well-defined bounds.
This effectively sets the internal filters to render the same way as the external filters.
This is only used if filtersAutoFocus is enabled.
The "context" is the framebuffer to which the Game Object is rendered. This is usually the main framebuffer, but might be another framebuffer. It can even be several different framebuffers if the Game Object is rendered multiple times.
Whether the Filters component should always draw to a framebuffer, even if there are no active filters.
A reference to the WebGLTextureWrapper this Shader is rendering to.
This property is only set if you have called Shader.setRenderToTexture.
ReadonlyhasA property indicating that a Game Object has this component.
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.
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.
If this Game Object is enabled for input then this property will contain an InteractiveObject instance.
Not usually set directly. Instead call GameObject.setInteractive().
The maximum size of the base filter texture. Filters may use a larger texture after the base texture is rendered. The maximum texture size is 4096 in WebGL. You may set this lower to save memory or prevent resizing.
The name of this Game Object. Empty by default and never populated by Phaser, this is left for developers to use.
ReadonlyoriginThe horizontal origin of this Game Object.
The origin maps the relationship between the size and position of the Game Object.
The default value is 0.5, meaning all Game Objects are positioned based on their center.
Setting the value to 0 means the position now relates to the left of the Game Object.
Set this value with setOrigin().
ReadonlyoriginThe vertical origin of this Game Object.
The origin maps the relationship between the size and position of the Game Object.
The default value is 0.5, meaning all Game Objects are positioned based on their center.
Setting the value to 0 means the position now relates to the top of the Game Object.
Set this value with setOrigin().
The parent Container of this Game Object, if it has one.
Whether any filters should be rendered on this Game Object.
This is true by default, even if there are no filters yet.
Disable this to skip filter rendering.
Use willRenderFilters() to see if there are any active filters.
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.
The underlying RenderNode object that the shader uses to render with.
ReadonlyrenderA flag that indicates if this Shader has been set to render to a texture instead of the display list.
This property is true if you have called Shader.setRenderToTexture, otherwise it's false.
A Shader that is rendering to a texture does not appear on the display list.
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.
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.
The horizontal scale of this Game Object.
The vertical scale of this Game Object.
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.
The horizontal scroll factor of this Game Object.
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.
The vertical scroll factor of this Game Object.
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.
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.
The Tab Index of the Game Object. Reserved for future use by plugins and the Input Manager.
A reference to the Phaser.Textures.Texture that has been stored in the Texture Manager for this Shader.
This property is only set if you have called Shader.setRenderToTexture with a key, otherwise it is null.
The bottom-left texture coordinate of the shader. This is set to 0,0 by default. It uses WebGL texture coordinates.
The bottom-right texture coordinate of the shader. This is set to 1,0 by default. It uses WebGL texture coordinates.
The top-left texture coordinate of the shader. This is set to 0,1 by default. It uses WebGL texture coordinates.
The top-right texture coordinate of the shader. This is set to 1,1 by default. It uses WebGL texture coordinates.
The textures that the shader uses.
These will be assigned to texture units 0 to N when the shader is
rendered, where N is textures.length - 1.
A textual representation of this Game Object, i.e. sprite.
Used internally by Phaser but is available for your own custom classes to populate.
The current vertex rounding mode of this Game Object. This is used by the WebGL Renderer to determine how to round the vertex positions. It can have several values:
off - No rounding is applied.safe - Rounding is applied if the object is 'safe'.safeAuto - Rounding is applied if the object is 'safe' and the camera has roundPixels enabled.full - Rounding is always applied.fullAuto - Rounding is always applied if the camera has roundPixels enabled.A 'safe' object is one that is not rotated or scaled by any transform matrix while rendering. The effective transform is a simple translation. In such cases, rounding will affect all vertices the same way.
Using full rounding can cause vertices to wobble, because they might not be aligned to the pixel grid. Full rounding gives a janky look like PS1 games.
You can use other values if you want to create your own custom rounding modes.
The visible state of the Game Object.
An invisible Game Object will skip rendering, but will still process update logic.
The w position of this Game Object.
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.
The x position of this Game Object.
The y position of this Game Object.
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.
Static ReadonlyRENDER_The bitmask that GameObject.renderFlags is compared against to determine if the Game Object will render or not.
This callback is invoked when this Game Object is added to a Scene.
Can be overriden by custom Game Objects, but be aware of some Game Objects that will use this, such as Sprites, to add themselves into the Update List.
You can also listen for the ADDED_TO_SCENE event from this Game Object.
Add a listener for a given event.
The event name.
The listener function.
Optionalcontext: anyThe context to invoke the listener with. Default this.
Add a render step.
The first render step in _renderSteps is run first.
It should call the next render step in the list.
This allows render steps to control the rendering flow.
The render step function to add.
Optionalindex: numberThe index in the render list to add the step to. Omit to add to the end.
Adds this Game Object to the given Display List.
If no Display List is specified, it will default to the Display List owned by the Scene to which this Game Object belongs.
A Game Object can only exist on one Display List at any given time, but may move freely between them.
If this Game Object is already on another Display List when this method is called, it will first be removed from it, before being added to the new list.
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.
OptionaldisplayList: DisplayList | LayerThe Display List to add to. Defaults to the Scene Display List.
Adds this Game Object to the Update List belonging to the Scene.
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(time, delta) within it, or it may fail to process required operations,
such as Sprite animations.
Copies an object's coordinates to this Game Object's position.
An object with numeric 'x', 'y', 'z', or 'w' properties. Undefined values are not copied.
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.
OptionalfromScene: booleanTrue if this Game Object is being destroyed by the Scene, false if not. Default false.
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.
OptionalresetCursor: booleanShould the currently active Input cursor, if any, be reset to the default cursor? Default false.
Calls each of the listeners registered for a given event.
The event name.
Additional arguments that will be passed to the event handler.
Enable this Game Object to have filters.
You need to call this method if you want to use the filterCamera
and filters properties. It sets up the necessary data structures.
You may disable filter rendering with the renderFilters property.
This is a WebGL only feature. It will return early if not available.
Return an array listing the events for which the emitter has registered listeners.
Focus the filter camera.
This sets the size and position of the filter camera to match the GameObject.
This is called automatically on render if filtersAutoFocus is enabled.
This will focus on the GameObject's raw dimensions if available. If the GameObject has no dimensions, this will focus on the context: the camera belonging to the DrawingContext used to render the GameObject. Context focus occurs during rendering, as the context is not known until then.
Manually override the focus of the filter camera.
This allows you to set the size and position of the filter camera manually.
It deactivates filtersAutoFocus when called.
The camera will set scroll to place the game object at the
given position within a rectangle of the given width and height.
For example, calling focusFiltersOverride(400, 200, 800, 600)
will focus the camera to place the object's center
100 pixels above the center of the camera (which is at 400x300).
Optionalx: numberThe x-coordinate of the focus point, relative to the filter size. Default is the center.
Optionaly: numberThe y-coordinate of the focus point, relative to the filter size. Default is the center.
Optionalwidth: numberThe width of the focus area. Default is the filter width.
Optionalheight: numberThe height of the focus area. Default is the filter height.

OptionalincludeParent: booleanIf this Game Object has a parent Container, include it (and all other ancestors) in the resulting vector? Default false.
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.
The key of the value to retrieve, or an array of keys.
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 an array containing the display list index of either this Game Object, or if it has one, its parent Container. It then iterates up through all of the parent containers until it hits the root of the display list (which is index 0 in the returned array).
Used internally by the InputPlugin but also useful if you wish to find out the display depth of this Game Object and all of its ancestors.
Gets the left-center coordinate of this Game Object, regardless of origin.
The returned point is calculated in local space and does not factor in any parent Containers,
unless the includeParent argument is set to true.
Optionaloutput: OAn object to store the values in. If not provided a new Vector2 will be created.
OptionalincludeParent: booleanIf this Game Object has a parent Container, include it (and all other ancestors) in the resulting vector? Default false.

OptionalincludeParent: booleanIf this Game Object has a parent Container, include it (and all other ancestors) in the resulting vector? Default false.
Returns the current value of a uniform from the render node. This value is actually copied to all shaders that use it. Modifications to non-primitive values such as arrays and objects will modify the original.
It's generally better to use the setupUniforms function in the
shader configuration object to set uniform values on changing uniforms.
This method is provided in the spirit of reading back the values.
The name of the uniform to get.
Gets the world position of this Game Object, factoring in any parent Containers.
Optionalpoint: Math.Vector2A Vector2, or point-like object, to store the result in.

Increase a value for the given key within this Game Objects Data Manager. If the key doesn't already exist in the Data Manager then it is increased from 0.
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.
When the value is first set, a setdata event is emitted from this Game Object.

ProtectedpreInternal destroy handler, called as part of the destroy process.
Remove all listeners, or those of the specified event.
Optionalevent: string | symbolThe event name.
This callback is invoked when this Game Object is removed from a Scene.
Can be overriden by custom Game Objects, but be aware of some Game Objects that will use this, such as Sprites, to removed themselves from the Update List.
You can also listen for the REMOVED_FROM_SCENE event from this Game Object.
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.
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.
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.)
OptionalresetCursor: booleanShould the currently active Input cursor, if any, be reset to the default cursor? Default false.
Remove the listeners of a given event.
The event name.
Optionalfn: FunctionOnly remove the listeners that match this function.
Optionalcontext: anyOnly remove the listeners that have this context.
Optionalonce: booleanOnly remove one-time listeners.
Render this object using filters.
This function's scope is not guaranteed, so it doesn't refer to this.
The WebGL Renderer instance to render with.
The Game Object being rendered.
The current drawing context.
OptionalparentMatrix: TransformMatrixThe parent matrix of the Game Object, if it has one.
OptionalrenderStep: numberThe index of this function in the Game Object's list of render processes. Used to support multiple rendering functions. Default 0.
Run a step in the render process. This is called automatically by the Render module.
In most cases, it just runs the renderWebGL function.
When _renderSteps has more than one entry,
such as when Filters are enabled for this object,
it allows those processes to defer renderWebGL
and otherwise manage the flow of rendering.
The WebGL Renderer instance to render with.
The Game Object being rendered.
The current drawing context.
OptionalparentMatrix: TransformMatrixThe parent matrix of the Game Object, if it has one.
OptionalrenderStep: numberWhich step of the rendering process should be run? Default 0.
OptionaldisplayList: GameObject[]The display list which is currently being rendered. If not provided, it will be created with the Game Object.
OptionaldisplayListIndex: numberThe index of the Game Object within the display list. Default 0.
Move this Game Object so that it appears above the given Game Object.
This means it will render immediately after the other object in the display list.
Both objects must belong to the same display list, or parent container.
This method does not change this Game Objects depth value, it simply alters its list position.
The Game Object that this Game Object will be moved to be above.
Sets the active property of this Game Object and returns this Game Object for further chaining.
A Game Object with its active property set to true will be updated by the Scenes UpdateList.
True if this Game Object should be set as active, false if not.
Sets the angle of this Game Object.
Optionaldegrees: numberThe rotation of this Game Object, in degrees. Default 0.
Move this Game Object so that it appears below the given Game Object.
This means it will render immediately under the other object in the display list.
Both objects must belong to the same display list, or parent container.
This method does not change this Game Objects depth value, it simply alters its list position.
The Game Object that this Game Object will be moved to be below.
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:
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.
The BlendMode value. Either a string, a CONST or a number.
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.
The key to set the value for. Or an object of key value pairs. If an object the data argument is ignored.
Optionaldata: anyThe value to set for the given key. If an object is provided as the key this argument is ignored.
Adds a Data Manager component to this Game Object.
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.
The depth of this Game Object. Ensure this value is only ever a number data-type.
Sets the display origin of this Game Object. The difference between this and setting the origin is that you can use pixel values for setting the display origin.
Optionalx: numberThe horizontal display origin value. Default 0.
Optionaly: numberThe vertical display origin value. If not defined it will be set to the value of x. Default x.
Sets the display size of this Game Object.
Calling this will adjust the scale.
The width of this Game Object.
The height of this Game Object.
Set whether filters should be updated every frame.
Sets the filtersAutoFocus property.
Whether filters should be updated every frame.
Set whether the filters should focus on the context.
Sets the filtersFocusContext property.
Whether the filters should focus on the context.
Set whether the filters should always draw to a framebuffer.
Sets the filtersForceComposite property.
Whether the object should always draw to a framebuffer, even if there are no active filters.
Set the base size of the filter camera. This is the size of the texture that internal filters will be drawn to. External filters are drawn to the size of the context (usually the game canvas).
This is typically the size of the GameObject.
It is set automatically when the Game Object is rendered
and filtersAutoFocus is enabled.
Turn off auto focus to set it manually.
Technically, larger framebuffers may be used to provide padding. This is the size of the final framebuffer used for "internal" rendering.
Base width of the filter texture.
Base height of the filter texture.
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.
OptionalhitArea: anyEither 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.
Optionalcallback: HitAreaCallbackThe 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.
OptionaldropZone: booleanShould this Game Object be treated as a drop zone target? Default false.
Sets the name property of this Game Object and returns this Game Object for further chaining.
The name property is not populated by Phaser and is presented for your own use.
The name to be given to this Game Object.
Sets the origin of this Game Object.
The values are given in the range 0 to 1.
Optionalx: numberThe horizontal origin value. Default 0.5.
Optionaly: numberThe vertical origin value. If not defined it will be set to the value of x. Default x.
Sets the origin of this Game Object based on the Pivot values in its Frame.
Sets the position of this Game Object.
Optionalx: numberThe x position of this Game Object. Default 0.
Optionaly: numberThe y position of this Game Object. If not set it will use the x value. Default x.
Optionalz: numberThe z position of this Game Object. Default 0.
Optionalw: numberThe w position of this Game Object. Default 0.
Sets the position of this Game Object to be a random position within the confines of the given area.
If no area is specified a random position between 0 x 0 and the game width x height is used instead.
The position does not factor in the size of this Game Object, meaning that only the origin is guaranteed to be within the area.
Optionalx: numberThe x position of the top-left of the random area. Default 0.
Optionaly: numberThe y position of the top-left of the random area. Default 0.
Optionalwidth: numberThe width of the random area.
Optionalheight: numberThe height of the random area.
Set whether the filters should be rendered.
Sets the renderFilters property.
Whether the filters should be rendered.
Changes this Shader so instead of rendering to the display list it renders to a WebGL Framebuffer and Texture instead. This allows you to use the output of this shader as a texture.
After calling this method the following properties are populated:
Shader.drawingContextShader.glTextureAdditionally, you can provide a key to this method.
Doing so will create a Phaser Texture from this Shader,
store it in Shader.texture,
and save it into the Texture Manager, allowing you to then use it for
any texture-based Game Object, such as a Sprite or Image:
var shader = this.add.shader('myShader', x, y, width, height);
shader.setRenderToTexture('doodle');
this.add.image(400, 300, 'doodle');
Note that it stores an active reference to this Shader. That means as this shader updates, so does the texture and any object using it to render with. Also, if you destroy this shader, be sure to clear any objects that may have been using it as a texture too.
By default it will create a single base texture. You can add frames to the texture
by using the Texture.add method. After doing this, you can then allow Game Objects
to use a specific frame from a Render Texture.
If you want to update a texture only sporadically, don't use this method. Instead, use a DynamicTexture:
var shader = this.add.shader('myShader', x, y, width, height);
var dynamic = this.textures.addDynamicTexture('myTexture', shader.width, shader.height);
// To update the texture:
dynamic.clear().draw(shader).render();
Optionalkey: stringThe unique key to store the texture as within the global Texture Manager.
Sets the rotation of this Game Object.
Optionalradians: numberThe rotation of this Game Object, in radians. Default 0.
Sets the scale of this Game Object.
Optionalx: numberThe horizontal scale of this Game Object. Default 1.
Optionaly: numberThe vertical scale of this Game Object. If not set it will use the x value. Default x.
Sets the scroll factor of this Game Object.
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.
The horizontal scroll factor of this Game Object.
Optionaly: numberThe vertical scroll factor of this Game Object. If not set it will use the x value. Default x.
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.
The width of this Game Object.
The height of this Game Object.
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.
The state of the Game Object.
Set the texture coordinates of the shader. These values are used to provide texture mapping to the shader, and are commonly used to drive generative output.
By default, the shader uses the whole texture, the range 0-1. The coordinates are in WebGL texture space, which is 0,0 in the bottom-left. This method allows you to specify a region of the texture to use, or even go outside the 0-1 bounds. This can be useful if you want to use a single frame from a texture, repeat the shader's texture, use a larger numeric range, or distort the shader.
Note that a quad is made of two triangles, divided by the diagonal from the top-left to the bottom-right. This means that some permutations of coordinates may affect just one or the other triangle. This can cause abrupt warping along the diagonal. Keep an eye on your output. Rectangles and parallelograms are safe bets. So are rotation and scaling transforms. Moving a single point is risky.
Call this method with no arguments to reset the shader to use the whole texture.
OptionaltopLeftX: numberThe top-left x coordinate of the texture. Default 0.
OptionaltopLeftY: numberThe top-left y coordinate of the texture. Default 1.
OptionaltopRightX: numberThe top-right x coordinate of the texture. Default 1.
OptionaltopRightY: numberThe top-right y coordinate of the texture. Default 1.
OptionalbottomLeftX: numberThe bottom-left x coordinate of the texture. Default 0.
OptionalbottomLeftY: numberThe bottom-left y coordinate of the texture. Default 0.
OptionalbottomRightX: numberThe bottom-right x coordinate of the texture. Default 1.
OptionalbottomRightY: numberThe bottom-right y coordinate of the texture. Default 0.
Set the texture coordinates of the shader from a frame. This is a convenience method that sets the texture coordinates to match a frame from a texture.
The frame to set the texture coordinates from. If a string is given, it will be used to look up the frame in the texture.
Optionaltexture: string | Textures.TextureThe texture that the frame is from. This is only used if frame is a string. If a string is given, it will be used to look up the texture in the Texture Manager. If not given, the first member of Shader.textures is used. If Shader.textures is empty, an error will occur.
Set the textures that the shader uses.
Some shaders don't use any textures. Some may use one or more.
The textures are assigned to texture units 0 to N when the shader is rendered,
where N is textures.length - 1.
You must set the uniforms in your shader to match these texture units.
Calling this method will replace the existing textures array with the new one.
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.
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.
Set the value of a uniform in the shader. This value is actually copied to all shaders that use it.
It's generally better to use the setupUniforms function in the
shader configuration object to set uniform values on changing uniforms.
Use this method to set uniforms just once.
The name of the uniform to set.
The value to set the uniform to.
The function which sets uniforms for the shader.
This is called automatically during rendering.
It is set from the config object passed in the constructor.
You should use this function to set any uniform values you need for your shader to run.
You can set this function directly after object creation,
but it's recommended to use the config object
to keep your logic encapsulated.
The function is invoked with two arguments: setUniform and drawingContext.
setUniform is a function that takes two arguments: a string (the name of the uniform) and a value.
Ensure that the value matches the expected type in the shader.
You don't need to be too precise, as the system will convert
e.g. Array and Float32Array types as needed.
To set an array in a shader, append [0] to the uniform name.
drawingContext is a reference to the current drawing context,
which may be useful if you need to query the camera or similar.
Note that uProjectionMatrixis set for you automatically.
The function which sets uniforms. (name: string, value: any) => void.
A reference to the current drawing context.
Sets the vertex round mode of this Game Object. This is used by the WebGL Renderer to determine how to round the vertex positions.
The vertex round mode to set. Can be 'off', 'safe', 'safeAuto', 'full' or 'fullAuto'.
Sets the visibility of this Game Object.
An invisible Game Object will skip rendering, but will still process update logic.
The visible state of the Game Object.
Sets the w position of this Game Object.
Optionalvalue: numberThe w position of this Game Object. Default 0.
Sets the x position of this Game Object.
Optionalvalue: numberThe x position of this Game Object. Default 0.
Sets the y position of this Game Object.
Optionalvalue: numberThe y position of this Game Object. Default 0.
Sets 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#setDepth instead.
Optionalvalue: numberThe z position of this Game Object. Default 0.
Removes all listeners.
Toggle a boolean value for the given key within this Game Objects Data Manager. If the key doesn't already exist in the Data Manager then it is toggled from false.
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.
When the value is first set, a setdata event is emitted from this Game Object.
The key to toggle the value for.
Returns a JSON representation of the Game Object.
To be overridden by custom GameObjects. Allows base objects to be used in a Pool.
args
Updates the Display Origin cached values internally stored on this Game Object. You don't usually call this directly, but it is exposed for edge-cases where you may.
Whether this Game Object will render filters.
This is true if it has active filters,
and if the renderFilters property is also true.
Checks if this Game Object should round its vertices,
based on the given Camera and the vertexRoundMode of this Game Object.
This is used by the WebGL Renderer to determine how to round the vertex positions.
You can override this method in your own custom Game Object classes to provide custom logic for vertex rounding.
A Shader Game Object.
This Game Object allows you to easily add a quad with its own shader into the display list, and manipulate it as you would any other Game Object, including scaling, rotating, positioning and adding to Containers. The Shader can be made interactive and used for input events. It can also be used in filters to create visually stunning effects.
It works by creating a custom RenderNode which runs a custom shader program to draw a quad. The shader program can be loaded from the Shader Cache, or provided in-line as strings.
Please see the Phaser 3 Examples GitHub repo for several examples of loading and creating shaders dynamically.
Due to the way in which they work, you cannot directly change the alpha of a Shader. It should be handled via uniforms in the shader code itself.
By default, a Shader has a uniform called
uProjectionMatrixwhich is set automatically. You can control additional uniforms using thesetupUniformsmethod in the Shader configuration object, which runs every time the shader renders.Shaders are stand-alone renders: they finish any current render batch and run once by themselves. As this costs a draw call, you should use them sparingly. If you need to have a fully batched custom shader, then please look at using a custom RenderNode instead. However, for background or special masking effects, they are extremely effective.
Note: be careful when using texture coordinates in shader code. The built-in variable
gl_FragCoordand the default uniformoutTexCoordboth use WebGL coordinates, which are0,0in the bottom-left. Additionally,gl_FragCoordsays it's in "window relative" coordinates. But this is actually relative to the framebuffer size.
