new Graphics(game, x, y)

A Graphics object is a way to draw primitives to your game. Primitives include forms of geometry, such as Rectangles,
Circles and Polygons. They also include lines, arcs and curves. When you initially create a Graphics object it will
be empty. To 'draw' to it you first specify a lineStyle or fillStyle (or both), and then draw a shape. For example:

graphics.beginFill(0xff0000);
graphics.drawCircle(50, 50, 100);
graphics.endFill();

This will draw a circle shape to the Graphics object, with a diameter of 100, located at x: 50, y: 50.

When a Graphics object is rendered it will render differently based on if the game is running under Canvas or
WebGL. Under Canvas it will use the HTML Canvas context drawing operations to draw the path. Under WebGL the
graphics data is decomposed into polygons. Both of these are expensive processes, especially with complex shapes.

If your Graphics object doesn't change much (or at all) once you've drawn your shape to it, then you will help
performance by calling Graphics.generateTexture. This will 'bake' the Graphics object into a Texture, and return it.
You can then use this Texture for Sprites or other display objects. If your Graphics object updates frequently then
you should avoid doing this, as it will constantly generate new textures, which will consume memory.

As you can tell, Graphics objects are a bit of a trade-off. While they are extremely useful, you need to be careful
in their complexity and quantity of them in your game.

Parameters:
Name Type Argument Default Description
game Phaser.Game

Current game instance.
x number <optional>

X position of the new graphics object.
y number <optional>

Members

alive :boolean

A useful flag to control if the Game Object is alive or dead.

This is set automatically by the Health components damage method should the object run out of health.
Or you can toggle it via your game code.

This property is mostly just provided to be used by your game - it doesn't effect rendering or logic updates.
However you can use Group.getFirstAlive in conjunction with this property for fast object pooling and recycling.

Inherited From:
Default Value:
  • true
Source - gameobjects/components/LifeSpan.js, line 50

angle :number

The angle property is the rotation of the Game Object in degrees from its original orientation.

Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.

Values outside this range are added to or subtracted from 360 to obtain a value within the range.
For example, the statement player.angle = 450 is the same as player.angle = 90.

If you wish to work in radians instead of degrees you can use the property rotation instead.
Working in radians is slightly faster as it doesn't have to perform any calculations.

Inherited From:
Source - gameobjects/components/Angle.js, line 29

animations :Phaser.AnimationManager

If the Game Object is enabled for animation (such as a Phaser.Sprite) this is a reference to its AnimationManager instance.
Through it you can create, play, pause and stop animations.

Source - gameobjects/components/Core.js, line 193
See:

autoCull :boolean

A Game Object with autoCull set to true will check its bounds against the World Camera every frame.
If it is not intersecting the Camera bounds at any point then it has its renderable property set to false.
This keeps the Game Object alive and still processing updates, but forces it to skip the render step entirely.

This is a relatively expensive operation, especially if enabled on hundreds of Game Objects. So enable it only if you know it's required,
or you have tested performance and find it acceptable.

Inherited From:
Source - gameobjects/components/AutoCull.js, line 28

blendMode :Number

The blend mode to be applied to the graphic shape. Apply a value of PIXI.blendModes.NORMAL to reset the blend mode.

Inherited From:
Default Value:
  • PIXI.blendModes.NORMAL;
Source - pixi/primitives/Graphics.js, line 61

body :Phaser.Physics.Arcade.Body|Phaser.Physics.P2.Body|Phaser.Physics.Ninja.Body|null

body is the Game Objects physics body. Once a Game Object is enabled for physics you access all associated
properties and methods via it.

By default Game Objects won't add themselves to any physics system and their body property will be null.

To enable this Game Object for physics you need to call game.physics.enable(object, system) where object is this object
and system is the Physics system you are using. If none is given it defaults to Phaser.Physics.Arcade.

You can alternatively call game.physics.arcade.enable(object), or add this Game Object to a physics enabled Group.

Important: Enabling a Game Object for P2 or Ninja physics will automatically set its anchor property to 0.5,
so the physics body is centered on the Game Object.

If you need a different result then adjust or re-create the Body shape offsets manually or reset the anchor after enabling physics.

Type:
Inherited From:
Source - gameobjects/components/PhysicsBody.js, line 91

bottom :number

The sum of the y and height properties.
This is the same as y + height - offsetY.

Inherited From:
Source - gameobjects/components/Bounds.js, line 168

boundsPadding :Number

The bounds' padding used for bounds calculation.

Inherited From:
Source - pixi/primitives/Graphics.js, line 96

cameraOffset :Phaser.Point

The x/y coordinate offset applied to the top-left of the camera that this Game Object will be drawn at if fixedToCamera is true.

The values are relative to the top-left of the camera view and in addition to any parent of the Game Object on the display list.

Inherited From:
Source - gameobjects/components/FixedToCamera.js, line 86

centerX :number

The center x coordinate of the Game Object.
This is the same as (x - offsetX) + (width / 2).

Inherited From:
Source - gameobjects/components/Bounds.js, line 58

centerY :number

The center y coordinate of the Game Object.
This is the same as (y - offsetY) + (height / 2).

Inherited From:
Source - gameobjects/components/Bounds.js, line 80

checkWorldBounds :boolean

If this is set to true the Game Object checks if it is within the World bounds each frame.

When it is no longer intersecting the world bounds it dispatches the onOutOfBounds event.

If it was previously out of bounds but is now intersecting the world bounds again it dispatches the onEnterBounds event.

It also optionally kills the Game Object if outOfBoundsKill is true.

When checkWorldBounds is enabled it forces the Game Object to calculate its full bounds every frame.

This is a relatively expensive operation, especially if enabled on hundreds of Game Objects. So enable it only if you know it's required,
or you have tested performance and find it acceptable.

  • This member is internal (protected) and may be modified or removed in the future.
Source - gameobjects/components/Core.js, line 167

data :Object

An empty Object that belongs to this Game Object.

by Phaser Plugins, to store data that needs to be associated with the Game Object,
without polluting the Game Object directly.

Inherited From:
Default Value:
  • {}

debug :boolean

A debug flag designed for use with Game.enableStep.

Inherited From:
Source - gameobjects/components/Core.js, line 218

<readonly> destroyPhase :boolean

As a Game Object runs through its destroy method this flag is set to true,
and can be checked in any sub-systems or plugins it is being destroyed from.

Inherited From:
Source - gameobjects/components/Destroy.js, line 22

events :Phaser.Events

All Phaser Game Objects have an Events class which contains all of the events that are dispatched when certain things happen to this
Game Object, or any of its components.

Inherited From:
Source - gameobjects/components/Core.js, line 185
See:

exists :boolean

Controls if this Game Object is processed by the core game loop.
If this Game Object has a physics body it also controls if its physics body is updated or not.
When exists is set to false it will remove its physics body from the physics world if it has one.
It also toggles the visible property to false as well.

Setting exists to true will add its physics body back in to the physics world, if it has one.
It will also set the visible property to true.

Inherited From:
Source - gameobjects/components/Core.js, line 284

fillAlpha :Number

The alpha value used when filling the Graphics object.

Inherited From:
Source - pixi/primitives/Graphics.js, line 18

fixedToCamera :boolean

A Game Object that is "fixed" to the camera uses its x/y coordinates as offsets from the top left of the camera during rendering.

The values are adjusted at the rendering stage, overriding the Game Objects actual world position.

The end result is that the Game Object will appear to be 'fixed' to the camera, regardless of where in the game world
the camera is viewing. This is useful if for example this Game Object is a UI item that you wish to be visible at all times
regardless where in the world the camera is.

The offsets are stored in the cameraOffset property.

Note that the cameraOffset values are in addition to any parent of this Game Object on the display list.

Be careful not to set fixedToCamera on Game Objects which are in Groups that already have fixedToCamera enabled on them.

Inherited From:
Source - gameobjects/components/FixedToCamera.js, line 56

<readonly> fresh :boolean

A Game Object is considered fresh if it has just been created or reset and is yet to receive a renderer transform update.
This property is mostly used internally by the physics systems, but is exposed for the use of plugins.

Inherited From:
Source - gameobjects/components/Core.js, line 248

game :Phaser.Game

A reference to the currently running Game.

Inherited From:
Source - gameobjects/components/Core.js, line 142

height :Number

The height of the displayObjectContainer, setting this will actually modify the scale to achieve the value set

Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 600

ignoreChildInput :Boolean

If ignoreChildInput is false it will allow this objects children to be considered as valid for Input events.

If this property is true then the children will not be considered as valid for Input events.

Note that this property isn't recursive: only immediate children are influenced, it doesn't scan further down.

Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 26

<readonly> inCamera :boolean

Checks if the Game Objects bounds intersect with the Game Camera bounds.
Returns true if they do, otherwise false if fully outside of the Cameras bounds.

Inherited From:
Source - gameobjects/components/AutoCull.js, line 37

input :Phaser.InputHandler|null

The Input Handler for this Game Object.

By default it is disabled. If you wish this Game Object to process input events you should enable it with: inputEnabled = true.

After you have done this, this property will be a reference to the Phaser InputHandler.

Type:
Inherited From:
Source - gameobjects/components/InputEnabled.js, line 24

inputEnabled :boolean

By default a Game Object won't process any input events. By setting inputEnabled to true a Phaser.InputHandler is created
for this Game Object and it will then start to process click / touch events and more.

You can then access the Input Handler via this.input.

Note that Input related events are dispatched from this.events, i.e.: events.onInputDown.

If you set this property to false it will stop the Input Handler from processing any more input events.

If you want to temporarily disable input for a Game Object, then it's better to set
input.enabled = false, as it won't reset any of the Input Handlers internal properties.
You can then toggle this back on as needed.

Inherited From:
Source - gameobjects/components/InputEnabled.js, line 42

<readonly> inWorld :boolean

Checks if the Game Objects bounds are within, or intersect at any point with the Game World bounds.

Inherited From:
Source - gameobjects/components/InWorld.js, line 129

isMask :Boolean

Inherited From:
Source - pixi/primitives/Graphics.js, line 88

key :string|Phaser.RenderTexture|Phaser.BitmapData|Phaser.Video|PIXI.Texture

The key of the image or texture used by this Game Object during rendering.
If it is a string it's the string used to retrieve the texture from the Phaser Image Cache.
It can also be an instance of a RenderTexture, BitmapData, Video or PIXI.Texture.
If a Game Object is created without a key it is automatically assigned the key __default which is a 32x32 transparent PNG stored within the Cache.
If a Game Object is given a key which doesn't exist in the Image Cache it is re-assigned the key __missing which is a 32x32 PNG of a green box with a line through it.

Type:
Inherited From:
Source - gameobjects/components/Core.js, line 203

left :number

This is the same as x - offsetX.

Inherited From:
Source - gameobjects/components/Bounds.js, line 102

lifespan :number

The lifespan allows you to give a Game Object a lifespan in milliseconds.

Once the Game Object is 'born' you can set this to a positive value.

It is automatically decremented by the millisecond equivalent of game.time.physicsElapsed each frame.
When it reaches zero it will call the kill method.

Very handy for particles, bullets, collectibles, or any other short-lived entity.

Inherited From:
Source - pixi/display/DisplayObjectContainer.js, line 55

alignIn(container, position, offsetX, offsetY) → {Object}

Aligns this Game Object within another Game Object, or Rectangle, known as the
'container', to one of 9 possible positions.

The container must be a Game Object, or Phaser.Rectangle object. This can include properties
such as World.bounds or Camera.view, for aligning Game Objects within the world
and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText,
TileSprites or Buttons.

Please note that aligning a Sprite to another Game Object does not make it a child of
the container. It simply modifies its position coordinates so it aligns with it.

The position constants you can use are:

Phaser.TOP_LEFT, Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_CENTER,
Phaser.CENTER, Phaser.RIGHT_CENTER, Phaser.BOTTOM_LEFT,
Phaser.BOTTOM_CENTER and Phaser.BOTTOM_RIGHT.

The Game Objects are placed in such a way that their bounds align with the
container, taking into consideration rotation, scale and the anchor property.
This allows you to neatly align Game Objects, irrespective of their position value.

The optional offsetX and offsetY arguments allow you to apply extra spacing to the final
aligned position of the Game Object. For example:

sprite.alignIn(background, Phaser.BOTTOM_RIGHT, -20, -20)

Would align the sprite to the bottom-right, but moved 20 pixels in from the corner.
Think of the offsets as applying an adjustment to the containers bounds before the alignment takes place.
So providing a negative offset will 'shrink' the container bounds by that amount, and providing a positive
one expands it.

Parameters:
Name Type Argument Default Description
container Phaser.Rectangle | Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Button | Phaser.Graphics | Phaser.TileSprite

The Game Object or Rectangle with which to align this Game Object to. Can also include properties such as World.bounds or Camera.view.
position integer <optional>

The position constant. One of Phaser.TOP_LEFT (default), Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_CENTER, Phaser.CENTER, Phaser.RIGHT_CENTER, Phaser.BOTTOM_LEFT, Phaser.BOTTOM_CENTER or Phaser.BOTTOM_RIGHT.
offsetX integer <optional>
 0

A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
offsetY integer <optional>
 0

A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
Returns:
Object -

This Game Object.

Inherited From:
Source - gameobjects/components/Bounds.js, line 223

alignTo(parent, position, offsetX, offsetY) → {Object}

Aligns this Game Object to the side of another Game Object, or Rectangle, known as the
'parent', in one of 11 possible positions.

The parent must be a Game Object, or Phaser.Rectangle object. This can include properties
such as World.bounds or Camera.view, for aligning Game Objects within the world
and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText,
TileSprites or Buttons.

Please note that aligning a Sprite to another Game Object does not make it a child of
the parent. It simply modifies its position coordinates so it aligns with it.

The position constants you can use are:

Phaser.TOP_LEFT (default), Phaser.TOP_CENTER, Phaser.TOP_RIGHT, Phaser.LEFT_TOP,
Phaser.LEFT_CENTER, Phaser.LEFT_BOTTOM, Phaser.RIGHT_TOP, Phaser.RIGHT_CENTER,
Phaser.RIGHT_BOTTOM, Phaser.BOTTOM_LEFT, Phaser.BOTTOM_CENTER
and Phaser.BOTTOM_RIGHT.

The Game Objects are placed in such a way that their bounds align with the
parent, taking into consideration rotation, scale and the anchor property.
This allows you to neatly align Game Objects, irrespective of their position value.

The optional offsetX and offsetY arguments allow you to apply extra spacing to the final
aligned position of the Game Object. For example:

sprite.alignTo(background, Phaser.BOTTOM_RIGHT, -20, -20)

Would align the sprite to the bottom-right, but moved 20 pixels in from the corner.
Think of the offsets as applying an adjustment to the parents bounds before the alignment takes place.
So providing a negative offset will 'shrink' the parent bounds by that amount, and providing a positive
one expands it.

Parameters:
Name Type Argument Default Description
parent Phaser.Rectangle | Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Button | Phaser.Graphics | Phaser.TileSprite

The Game Object or Rectangle with which to align this Game Object to. Can also include properties such as World.bounds or Camera.view.
position integer <optional>

offsetX integer <optional>
 0

A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
offsetY integer <optional>
 0

A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
Returns:
Object -
