Namespace: Mask
Phaser.GameObjects.Components.Mask

Members

Description:

The Mask this Game Object is using during render.

Type:
Since: 3.0.0
Focus
Focus

Methods

setMask(mask)
Focus
Focus

Description:

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.

Returns:
Description:

This Game Object instance.

Examples:
Since: 3.6.2

Parameters:

name type arguments Default description

Returns:
Description:

Examples:

createBitmapMask([renderable])
Focus
Focus

Description:

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 arguments description
renderable Phaser.GameObjects.GameObject <optional>

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

Returns:
Description:

This Bitmap Mask that was created.

Examples:
Since: 3.6.2
Focus
Focus
createGeometryMask([graphics])
Focus
Focus

Description:

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 arguments description
graphics Phaser.GameObjects.Graphics <optional>

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

Returns:
Description:

This Geometry Mask that was created.
