Trying to get the player sprite to change directions with player movement

Help

Godot Version

func process_physics(_delta) -> State:
	if parent.movement:
		parent.velocity.x = speed * parent.movement * _delta
		if parent.movement > 0:
			parent.animation.flip_h = -1
		elif parent.movement < 0:
			parent.animation.flip_h = 1
	else:
		parent.velocity.x = 0

Question

only the first time does the player turn around when an opposite direction is pressed, but everytime after that nothing happens.

Hi,

flip_h being a boolean, you should assign either 0 (for false) or 1 (for true). Here, your -1 will not work properly.
Even better (and actually advised as everyone does that), assign true or false directly:

if parent.movement > 0:
    parent.animation.flip_h = false
elif parent.movement < 0:
    parent.animation.flip_h = true
