Phaser. Image

new Image(game, x, y, key, frame)

An Image is a light-weight object you can use to display anything that doesn't need physics or animation. It can still rotate, scale, crop and receive input events. This makes it perfect for logos, backgrounds, simple buttons and other non-Sprite graphics.

Parameters:
Name Type Description
game Phaser.Game

A reference to the currently running game.

x number

The x coordinate of the Image. The coordinate is relative to any parent container this Image may be in.

y number

The y coordinate of the Image. The coordinate is relative to any parent container this Image may be in.

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

The texture used by the Image during rendering. It can be a string which is a reference to the Cache entry, or an instance of a RenderTexture, BitmapData or PIXI.Texture.

frame string | number

If this Image is using part of a sprite sheet or texture atlas you can specify the exact frame to use by giving a string or numeric index.

Extends

Members

alive :boolean

A useful boolean to control if the Image is alive or dead (in terms of your gameplay, it doesn't effect rendering).

Default Value:
  • true
Source - gameobjects/Image.js, line 86

alpha :Number

The opacity of the object.

Inherited From:
Source - pixi/display/DisplayObject.js, line 65

anchor :PIXI.Point

The anchor sets the origin point of the texture. The default is 0,0 this means the texture's origin is the top left Setting than anchor to 0.5,0.5 means the textures origin is centered Setting the anchor to 1,1 would mean the textures origin points will be the bottom right corner

Inherited From:
Source - pixi/display/Sprite.js, line 22

angle :number

Indicates the rotation of the Image, 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 use the property Image.rotation instead. Working in radians is also a little faster as it doesn't have to convert the angle. The angle of this Image in degrees.

Source - gameobjects/Image.js, line 741

animations :Phaser.AnimationManager

This manages animations of the sprite. You can modify animations through it (see Phaser.AnimationManager)

Source - gameobjects/Image.js, line 63

autoCull :boolean

Should this Image be automatically culled if out of range of the camera? A culled sprite has its renderable property set to 'false'. Be advised this is quite an expensive operation, as it has to calculate the bounds of the object every frame, so only enable it if you really need it. A flag indicating if the Image should be automatically camera culled or not.

Default Value:
  • false
Source - gameobjects/Image.js, line 96

blendMode :Number

The blend mode to be applied to the sprite. Set to PIXI.blendModes.NORMAL to remove any blend mode.

Inherited From:
Default Value:
  • PIXI.blendModes.NORMAL;

buttonMode :Boolean

This is used to indicate if the displayObject should display a mouse hand cursor on rollover

Inherited From:
Source - pixi/display/DisplayObject.js, line 90

cacheAsBitmap :Boolean

Set if this display object is cached as a bitmap. This basically takes a snap shot of the display object as it is at that moment. It can provide a performance benefit for complex static displayObjects. To remove simply set this property to 'null'

Inherited From:
Source - pixi/display/DisplayObject.js, line 436

cameraOffset :Phaser.Point

If this object is fixedToCamera then this stores the x/y offset that its drawn at, from the top-left of the camera view.

Default Value:
  • false
Source - gameobjects/Image.js, line 107

  • true
Source - gameobjects/Image.js, line 36

filterArea :PIXI.Rectangle

The area the filter is applied to like the hitArea this is used as more of an optimisation rather than figuring out the dimensions of the displayObject each frame you can set this rectangle

Inherited From:
Source - pixi/display/DisplayObject.js, line 180

filters :Array.<Filter>

Sets the filters for the displayObject. IMPORTANT: This is a webGL only feature and will be ignored by the canvas renderer. To remove filters simply set this property to 'null'

Type:
  • Array.<Filter>
Inherited From:
Source - pixi/display/DisplayObject.js, line 400

fixedToCamera :boolean

An Image that is fixed to the camera uses its x/y coordinates as offsets from the top left of the camera. These are stored in Image.cameraOffset. Note that the cameraOffset values are in addition to any parent in the display list. So if this Image was in a Group that has x: 200, then this will be added to the cameraOffset.x Set to true to fix this Image to the Camera at its current world coordinates.

Source - gameobjects/Image.js, line 963

frame :number

Type:
Inherited From:
Source - pixi/display/DisplayObject.js, line 81

<readonly> inCamera :boolean

mask :PIXI.Graphics

Sets a mask for the displayObject. A mask is an object that limits the visibility of an object to the shape of the mask applied to it. In PIXI a regular mask must be a PIXI.Graphics object. This allows for much faster masking in canvas as it utilises shape clipping. To remove a mask, set this property to null.

crop(rect, copy)

Crop allows you to crop the texture used to display this Image. Cropping takes place from the top-left of the Image and can be modified in real-time by providing an updated rectangle object. The rectangle object given to this method can be either a Phaser.Rectangle or any object so long as it has public x, y, width and height properties. Please note that the rectangle object given is not duplicated by this method, but rather the Image uses a reference to the rectangle. Keep this in mind if assigning a rectangle in a for-loop, or when cleaning up for garbage collection.

Parameters:
Name Type Argument Default Description
rect Phaser.Rectangle

The Rectangle used during cropping. Pass null or no parameters to clear a previously set crop rectangle.

copy boolean <optional>
false

If false Sprite.cropRect will be a reference to the given rect. If true it will copy the rect values into a local Sprite.cropRect object.

destroy(destroyChildren)

Destroys the Image. This removes it from its parent group, destroys the input, event and animation handlers if present and nulls its reference to game, freeing it up for garbage collection.

Parameters:
Name Type Argument Default Description
destroyChildren boolean <optional>
true

Should every child of this object have its destroy method called?

Source - gameobjects/Image.js, line 514

frame Phaser.Frame

The Frame to be used by the Image texture.

Source - gameobjects/Image.js, line 314

setScaleMinMax(minX, minY, maxX, maxY)

Sets the scaleMin and scaleMax values in one call. These values are used to limit how far this Image will scale (either up or down) based on its parent. For example if this Image has a minScale value of 1 and its parent has a scale value of 0.5, the 0.5 will be ignored and the scale value of 1 will be used. By using these values you can carefully control how Images deal with responsive scaling.

If only one parameter is given then that value will be used for both scaleMin and scaleMax: setScaleMinMax(1) = scaleMin.x, scaleMin.y, scaleMax.x and scaleMax.y all = 1

If only two parameters are given the first is set as scaleMin.x and y and the second as scaleMax.x and y: setScaleMinMax(0.5, 2) = scaleMin.x and y = 0.5 and scaleMax.x and y = 2

If you wish to set scaleMin with different values for x and y then either modify Image.scaleMin directly, or pass null for the maxX and maxY parameters.

Call setScaleMinMax(null) to clear both the scaleMin and scaleMax values.

Parameters:
Name Type Description
minX number | null

The minimum horizontal scale value this Image can scale down to.

minY number | null

The minimum vertical scale value this Image can scale down to.

maxX number | null

The maximum horizontal scale value this Image can scale up to.

maxY number | null
