I used Phaser.Actions.RotateAroundDistance(spinningfire.getChildren(), { x: 600, y: -1780 }, 0.02, 200)
in order to make a the group spinning fire to spin around a sprite. the only problem is that the hitbox does not move with the fire image.
I am VERY new to phaser so I really do not have any idea on how to change hitboxes and other complicated stuff like this.
