Phaser . GameObjects . Group

A Group is a way for you to create, manipulate, or recycle similar Game Objects.

Group membership is non-exclusive. A Game Object can belong to several groups, one group, or none.

Groups themselves aren't displayable, and can't be positioned, rotated, scaled, or hidden.

Constructor:

new Group(scene, [children], [config])

Parameters:

name type arguments description
scene Phaser.Scene

The scene this group belongs to.
children Array.<Phaser.GameObjects.GameObject> | Phaser.Types.GameObjects.Group.GroupConfig | Phaser.Types.GameObjects.Group.GroupCreateConfig <optional>

Game Objects to add to this group; or the config argument.
config Phaser.Types.GameObjects.Group.GroupConfig | Phaser.Types.GameObjects.Group.GroupCreateConfig <optional>
