Room class

Rooms are the entities that contain all the copies, backgrounds, tile layers, and advanced entities, too. They are also referred to as maps and levels.

Rooms derive from PIXI.Container class, and inherit all its methods and properties.

The current room, rooms.current.

rooms.current always points to the current room. If you have multiple rooms layered on top of each other, rooms.current will point to the initial room that was created at the start of a game, or after calling rooms.switch.

To get layered rooms, you can use rooms.list, or this.getRoom inside copies' events.

UI and Gameplay rooms

Rooms can be put either into UI coordinate space or gameplay coordinate space. Gameplay rooms are managed by ct.camera, and cannot be moved manually. But UI rooms can be: for example, to move smaller widgets around the viewport.

Tips

More about this concept at Game and UI Coordinates. For viewport management, see Working with Viewport.

Notable properties

Property	Type	Description
alpha	number	A value from 0 to 1 that sets the room's opacity. You can use it, for example, to gradually fade in/fade out UI layers. 0 means fully transparent, and 1 means fully opaque.
isUi	boolean	If set to true, the room will be unaffected by camera scaling, movement, and rotation. See more at Game and UI Coordinates.
x, y	number	The location of a room. Changing these has no effect if the room is in gameplay coordinates (if its isUi property is false)
