Infinite Backgrounds in Godot

The parallax nodes makes infinite backgrounds in godot really easy.

Add these three nodes to your background scene:

ParallaxBackground
--┖╴ParallaxLayer
---- ┖╴Sprite

Then add your background image to the sprite. On the parallaxLayer node set the mirroring x and y to the dimensions of your background image.

the background will keep up with the camera, so however you move the camera the background will be handled automatically.

if you are building something like a title screen, without a camera node, then you can handle the scroll manually.

constantly move the background to the right:

extends ParallaxBackground

func _process(delta):
    scroll_offset.x += 1000 * delta

or move the background in a circle:

extends ParallaxBackground

export(int) var speed: int = 1000
export(float) var rotation_speed = 0.4

var direction = Vector2(1, 0)

func _process(delta):
    scroll_offset += direction * speed * delta
    direction = direction.rotated(rotation_speed * delta)
