Lists properties
The Lists property is not part of the Phaser API. It is a property used by the Scene Editor to add objects to a list. It is the “parent lists” of the object.
As you can learn in the Object List section, the editor allows to group objects in lists.
The button next to the property shows the lists that the object belongs to. You can click on the button to:
Add the object to another list.
Remove the object from a list.
