I'm writing an asteroids-type game in Godot 4.3, wherein the ship checks if it's off the screen and then moves itself to the opposite edge of the screen.

My first attempt, the following code lives in my ship node's script:

const SCREEN_WRAP_MARGIN = 10

func _process(delta: float) -> void:
    # if ship leaves the screen, wrap around
    if position.x < -SCREEN_WRAP_MARGIN:
        position.x += screen_size.x + SCREEN_WRAP_MARGIN* 2
        print("x < " , -SCREEN_WRAPAROUND_MARGIN, " at ", position.x)
    # ... etc...

Bizarrely, when I run that code, the ship seems to correctly wrap from off the left side of the screen onto the right side. BUT the ship sprite starts flickering, and that condition evaluates every frame, logging a blatantly impossible message:

x < -10 at 1023.29853

The following code works, which I figured out based on this reddit thread

    position.x = wrapf(position.x, -SCREEN_WRAP_MARGIN, screen_size.x + SCREEN_WRAP_MARGIN)
    # ... etc...

I intuit that this strange behavior is related to the behavior of the underlying classes. My ship inherits from RigidBody2D, CollisionObject2D, Node2D, CanvasItem, and Node.

But...why?
