Moving Kinematic2D body along Navigation2D path

LordSmooches

So I am trying to get an an enemy to move along a path. It seems to go to the correct position however it doesn't smoothly go there. Once I hit the space button it instantly travels there. I am not sure how to do this. I originally thought that you should use move_and_slide for this but it has the same issue. I have tried linear_interpolation and lerp as well and nothing seems to be working correctly. Here is my move code.

func walk():
	var tilemap = get_node("../Navigation2D/GroundTileMap")

	rand.randomize()	
	var cells = tilemap.get_used_cells()
	var randindex = rand.randi_range(0, cells.size())
	var tile_center = tilemap.map_to_world(cells[150]) + tilemap.cell_size / 2
	
	var points = get_node("../Navigation2D").get_simple_path(get_global_position(), tile_center, false)
	
	var start_point = get_global_position()
	if points.size() > 0:
		for i in range(points.size()):
			var distance = points[0] - start_point
			if distance.length() > stop_distance and points.size() > 2:
				position = lerp(start_point, points[0], 2)
			else:
				position = points[0]
				break
			
			start_point = points[0]
			points.remove(0)

The cell portion or top part of the code is just getting a random tile in the scene to move to. I start off with gettting the start point which is just the global position. I then loop through the points along the path. I grab the distance and check to see if it is greater the stop distance which right now is 1.5. I also check the size of the points. then if those check out I start to lerp. But it just instantly moves to that position. At the end of the loop I set the start point to the starting point and remove the old start point from the array. I am not sure what Im doing wrong. This is all called when I hit the space bar like below.

func _process(delta):
	if Input.is_action_just_released("ui_select"):
		walk()

If someone could help out with this that would be awesome

EDIT : I updated the loop to a while loop since it makes more sense

	while points.size() >= 1:
		var distance = points[0] - start_point
		if distance.length() > stop_distance and points.size() > 1:
#			position = start_point.linear_interpolate(points[0], speed)
			position = lerp(start_point, points[0], 2)
		else:
			position = points[0]
			break
			
		start_point = points[0]
		points.remove(0)

I think the last two statements need to be in the else clause, but I think you would do the remove first and then set the start point. Anyway, with those in the loop you remove the 0 position at each cycle if the loop.

Ok I have figured out the move now, I updated the function and removed the loop altogether. The enemy is now moving which is what I was looking for. Unfortunately it moves diagonally which means I might have to switch over to A* class to remove the diagonal movement. Thanks all
