How to spawn a scene when player camera reaches the end of that scene?

TheSnowmannDev

I have been googling to no luck so decided it's time to ask another question on the forum.

Essentially, I have a Kinematic2D (Player) set up with a Camera2D attached as a child. I have instanced the player into a scene (currently named Test Scene). In that scene I have a few other node instances like a StaticBody2D (ground) and a ParallaxBackground (Sky). I am trying to figure a way to spawn another ground instance when my players camera2D reaches the bounds of the previous ground on the x axis. I am creating, or trying to, a small endless runner. Parallaxing works now but I want to get the ground to repeat as well.

However, it is a staticbody2d and not a ParallaxBackground. If I create the ground node as a ParallaxBackground with the ParallaxLayer and a StaticBody2D on that ParallaxLayer the player will fall straight through it, so I had to go the route I am trying to go.

As this is a endless runner my GroundMovement.gd looks like this:

extends StaticBody2D

export var groundSpeed = 20

func _physics_process(delta):
    self.constant_linear_velocity.x += groundSpeed

    if constant_linear_velocity.x > groundSpeed:
	    constant_linear_velocity.x = groundSpeed

Which works well for getting my player to move across it like a conveyer belt. I just need it to spawn again as my Camera2D reaches the bounds of it. Ground sprite is 240px and my camera is 240px. I would also like to delete the previous Ground.tscn instance as it leaves the bounds of the camera.

Any tips or tricks is appreciated.

The basic idea is to have a script checking the x position of the floor and adding/removing it when it goes past a certain distance (such as the width of the ground in relation to the camera position). I found it is most optimized to create 2 pieces of ground, and then never remove them. When one goes off the screen, just move it to the next position past the ground that is still on screen. This avoids stalls when adding/removing objects. The ground nodes can have different layers you show and hide if there are different terrains.
