active :boolean

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:
  • boolean
Since: 3.0.0
Inherited From:
Default Value:
  • true
Source: src/gameobjects/GameObject.js (Line 95)

angle :integer

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:
  • integer

Phaser.GameObjects.Particles.ParticleEmitterManager

createBitmapMask( [renderable])

Creates and returns a Bitmap 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 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 Game Object.

Parameters:
Name Type Argument Description
renderable Phaser.GameObjects.GameObject <optional>

A renderable Game Object that uses a texture, such as a Sprite.

Since: 3.6.2
Inherited From:
Source: src/gameobjects/components/Mask.js (Line 80)
Returns:

This Bitmap Mask that was created.

Source: src/gameobjects/particles/ParticleEmitterManager.js (Line 265)
Returns:

The Particle Emitter that was created.

Type
Phaser.GameObjects.Particles.ParticleEmitter

createGeometryMask( [graphics])

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 Argument Description
graphics Phaser.GameObjects.Graphics <optional>

A Graphics Game Object. The geometry within it will be used as the mask.

Since: 3.6.2

Type
Phaser.GameObjects.Particles.GravityWell

destroy( [fromScene])

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 Argument Default Description
fromScene boolean <optional>
false

Is this Game Object being destroyed as the result of a Scene shutdown?

Since: 3.0.0
Inherited From:
Source: src/gameobjects/GameObject.js (Line 545)
Fires:

disableInteractive()

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.

Since: 3.7.0
Inherited From:
Source: src/gameobjects/GameObject.js (Line 402)
Returns:

This GameObject.

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

removeInteractive()

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.)

Returns:

This Game Object instance.

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

setData(key [, data])

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 Argument Description
key string | object

The key to set the value for. Or an object of key value pairs. If an object the data argument is ignored.

data * <optional>

The value to set for the given key. If an object is provided as the key this argument is ignored.

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

setDepth(value)

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 depth starts from zero (the default value) and increases from that point. 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 integer

The depth of this Game Object.

Inherited From:
Source: src/gameobjects/components/Depth.js (Line 58)
Returns:

Parameters:
Name Type Description
frames Phaser.Textures.Frame | Array.<Phaser.Textures.Frame>

The texture frames.

emitter Phaser.GameObjects.Particles.ParticleEmitter

The particle emitter to modify.

Since: 3.0.0

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

setFrame( [frame])

Sets the frame this Emitter Manager will use to render with.

The Frame has to belong to the current Texture being used.

It can be either a string or an index.

Parameters:
Name Type Argument Description
frame string | integer <optional>

The name or index of the frame within the Texture.

Since: 3.0.0
Source: src/gameobjects/particles/ParticleEmitterManager.js (Line 172)
Returns:

This Emitter Manager.

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

setInteractive( [shape] [, callback] [, dropZone])

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 Argument Default Description
shape Phaser.Types.Input.InputConfiguration | any <optional>

Either an input configuration object, or a geometric shape that defines the hit area for the Game Object. If not specified a Rectangle will be used.

callback Phaser.Types.Input.HitAreaCallback <optional>

A callback to be invoked when the Game Object is interacted with. 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?

Source: src/gameobjects/GameObject.js (Line 373)
Returns:

Type
Phaser.GameObjects.Particles.ParticleEmitterManager

setMask(mask)

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.

setState(value)

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
