scrollFactorX :number

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.

createBitmapMask( [renderable])

Creates and returns a Bitmap Mask. This mask can be used by any Game Object, including this one.

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 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:

Type
Phaser.Display.Masks.BitmapMask

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.

setBlendMode(value)

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:

  • ADD
  • MULTIPLY
  • SCREEN
  • ERASE (only works when rendering to a framebuffer, like a Render Texture)

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.

Parameters:
Name Type Description
value string | Phaser.BlendModes

The BlendMode value. Either a string or a CONST.

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.

setScrollFactor(x [, y])

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.

Parameters:
Name Type Argument Default Description
x number

The horizontal scroll factor of this Game Object.
y number <optional>
 x

The vertical scroll factor of this Game Object. If not set it will use the x value.
