Oh yeap sure thing.
I don't have a camera2d.tscn in the project.
The project has a world node that contains:
1) PlayerNode
2) Camera2D
3) WallNode (5x)
4) CanvasLayer
In the World and WallNodes, there is only a _physics_process
function that moves the WallNodes by a Vector2.
In the PlayerNode, there are logic to:
1) Move the playerNode vertically (falling down usually and UP on 'space' keypress
2) Detect collision with the Walls
3) Reset the Walls that go out of bound
4) Display the score via CanvasLayer
As such there is no reference to the Camera2D except being a child of the World node.
Hope this helps, thank you
