## This is a very basic way of implementing randomness in Godot.
## If you need more depth on randomness and how to implement: https://docs.godotengine.org/en/stable/tutorials/math/random_number_generation.html
## Returns a random SpriteSkin from an array containing paths to skins.

	array.shuffle() # Shuffle the array because why not.
	
	var random_skin = array[rng.randi() % array.size()]
	var skin: SpineSkin = sprite.get_skeleton().get_data().find_skin(random_skin)
