I'm having trouble rewriting the algorithm that's responsible for filling in the color.

Would someone help me rewrite it to gdscript? There's still some bugs popping up and I can't quite do it. I use these variables at the start

var oldcolor = Color(1,1,1,1)
var newcolor = Color( 0.6, 0.7, 0.8, 0.8 )
var ccolor = Color(0, 0, 0, 1)
var edgecolour = Color(0,0,0,1)
var seed =get_global_mouse_position()
var myimage = preload("res://Untitled2.jpg").get_data()
var obrazek = ImageTexture.new()

func _ready():
	myimage = preload("res://Untitled2.jpg").get_data()
	obrazek.create_from_image(myimage)
	myimage.lock()
	$Sprite.set_texture(obrazek)

func _input(event):
	if Input.is_action_just_pressed("lpm"):
		seed=get_global_mouse_position()
		x = seed.x
		y = seed.y    
		obrazek.create_from_image(myimage)

I write on comment box not in GD program nor test so there may be some mistake. Also I write kinda difference algorithm from your.

func bucket_fill(image, position, color):
	image.lock()
	var queue = [position]
	var old_color = image.get_pixelv(position)
	while !queue.empty():
		var pop = queue.pop_back()
		if image.get_pixelv(pop) == old_color:
			image.set_pixelv(pop, color)
			for x in range(image.get_size.x -1, image.get_size.x + 2):
				for y in range(image.get_size.y - 1, image.get_size.y + 2):
					if x == pop.x || y == pop.y:
						queue.append(Vector2(x, y))
	image.unlock()
