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. Shaders can be masked with either Bitmap or Geometry masks and can also be used as a Bitmap Mask for a Camera or other Game Object. They can also be made interactive and used for input events.
It works by taking a reference to a Phaser.Display.BaseShader
instance, as found in the Shader Cache. These can
be created dynamically at runtime, or loaded in via the GLSL File Loader:
function preload ()
{
this.load.glsl('fire', 'shaders/fire.glsl.js');
}
function create ()
{
this.add.shader('fire', 400, 300, 512, 512);
}
Please see the Phaser 3 Examples GitHub repo for examples of loading and creating shaders dynamically.
Due to the way in which they work, you cannot directly change the alpha or blend mode of a Shader. This should be handled via exposed uniforms in the shader code itself.
By default a Shader will be created with a standard set of uniforms. These were added to match those found on sites such as ShaderToy or GLSLSandbox, and provide common functionality a shader may need, such as the timestamp, resolution or pointer position. You can replace them by specifying your own uniforms in the Base Shader.
These Shaders work by halting the current pipeline during rendering, creating a viewport matched to the size of this Game Object and then renders a quad using the bound shader. At the end, the pipeline is restored.
Because it blocks the pipeline it means it will interrupt any batching that is currently going on, so you should use these Game Objects sparingly. If you need to have a fully batched custom shader, then please look at using a custom pipeline instead. However, for background or special masking effects, they are extremely effective.
new Shader(scene, key, [x], [y], [width], [height], [textures], [textureData])
name | type | arguments | Default | 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.
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.
If this Game Object is enabled for Arcade or Matter Physics then this property will contain a reference to a Physics Body.
Uint8 view to the vertex raw buffer. Used for uploading vertex buffer resources to the GPU.
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.
A reference to the GL Frame Buffer this Shader is drawing to.
This property is only set if you have called Shader.setRenderToTexture
.
The WebGL context belonging to the renderer.
A reference to the WebGLTexture this Shader is rendering to.
This property is only set if you have called Shader.setRenderToTexture
.
A 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 Mask this Game Object is using during render.
The name of this Game Object. Empty by default and never populated by Phaser, this is left for developers to use.
The 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()
.
The 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.
The pointer bound to this shader, if any.
Set via the chainable setPointer
method, or by modifying this property directly.
The WebGL shader program this shader uses.
The projection matrix the shader uses during rendering.
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.
A 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.
A reference to the current renderer. Shaders only work with the WebGL Renderer.
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 underlying shader object being used.
Empty by default and set during a call to the setShader
method.
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
, otherwise it is null
.
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 default uniform mappings. These can be added to (or replaced) by specifying your own uniforms when creating this shader game object. The uniforms are updated automatically during the render step.
The defaults are:
resolution
(2f) - Set to the size of this shader.
time
(1f) - The elapsed game time, in seconds.
mouse
(2f) - If a pointer has been bound (with setPointer
), this uniform contains its position each frame.
date
(4fv) - A vec4 containing the year, month, day and time in seconds.
sampleRate
(1f) - Sound sample rate. 44100 by default.
iChannel0...3
(sampler2D) - Input channels 0 to 3. null
by default.
The WebGL vertex buffer object this shader uses.
Raw byte buffer of vertices this Shader uses.
Float32 view of the array buffer containing the shaders vertices.
The view matrix the shader uses during rendering.
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.

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.
name | type | arguments | description |
---|---|---|---|
displayList | Phaser.GameObjects.DisplayList | Phaser.GameObjects.Layer | <optional> |
The Display List to add to. Defaults to the Scene Display List. |
This Game Object.
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(delta, time)
within it, or it may fail to process required operations,
such as Sprite animations.
This Game Object.
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.
Clears the mask that this Game Object was using.
name | type | arguments | Default | description |
---|---|---|---|---|

This Game Object instance.
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.
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. |
This Bitmap Mask that was created.
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.
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. |
This Geometry Mask that was created.
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.
name | type | arguments | Default | description |
---|---|---|---|---|
fromScene | boolean | <optional> | 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.

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.
This Game Object.
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.
This Game Object.
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.)

This Shader instance.
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 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.

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.
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? |
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);
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.
name | type | description |

mask | Phaser.Display.Masks.BitmapMask | Phaser.Display.Masks.GeometryMask |

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.

Changes this Shader so instead of rendering to the display list it renders to a WebGL Framebuffer and WebGL Texture instead. This allows you to use the output of this shader as an input for another shader, by mapping a sampler2D uniform to it.
After calling this method the Shader.framebuffer
and Shader.glTexture
properties
are populated.
Additionally, you can provide a key to this method. Doing so will create a Phaser Texture from this Shader 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.
You can access the Phaser Texture that is created via the Shader.texture
property.
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.
name | type | arguments | Default | description |

Sets a sampler2D uniform on this shader.
The textureKey given is the key from the Texture Manager cache. You cannot use a single frame from a texture, only the full image. Also, lots of shaders expect textures to be power-of-two sized.
If you wish to use another Shader as a sampler2D input for this shader, see the Shader.setSampler2DBuffer
method.

The key of the sampler2D uniform to be updated, i.e. |
|
textureKey | string |
The key of the texture, as stored in the Texture Manager. Must already be loaded. |
|
textureIndex | number | <optional> |
The texture index. |
textureData | any | <optional> |
Additional texture data. |
This Shader instance.
Sets a sampler2D uniform on this shader where the source texture is a WebGLTexture.
This allows you to feed the output from one Shader into another:
let shader1 = this.add.shader(baseShader1, 0, 0, 512, 512).setRenderToTexture();
let shader2 = this.add.shader(baseShader2, 0, 0, 512, 512).setRenderToTexture('output');
shader1.setSampler2DBuffer('iChannel0', shader2.glTexture, 512, 512);
shader2.setSampler2DBuffer('iChannel0', shader1.glTexture, 512, 512);
In the above code, the result of baseShader1 is fed into Shader2 as the iChannel0
sampler2D uniform.
The result of baseShader2 is then fed back into shader1 again, creating a feedback loop.
If you wish to use an image from the Texture Manager as a sampler2D input for this shader,
see the Shader.setSampler2D
method.

Sets the scale of this Game Object.
name | type | arguments | Default | description |

The horizontal scale of this Game Object. |
y | number | <optional> | x |
The vertical scale of this Game Object. If not set it will use the |
This Game Object instance.
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.

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.

width | number |
The width of this Game Object. |
height | number |

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.

Sets a property of a uniform already present on this shader.
To modify the value of a uniform such as a 1f or 1i use the value
property directly:
shader.setUniform('size.value', 16);
You can use dot notation to access deeper values, for example:
shader.setUniform('resolution.value.x', 512);
The change to the uniform will take effect the next time the shader is rendered.
