hello guys, here is a code for enemy’s ai,

extends CharacterBody2D
@export var patrol_points : Node
enum State {Idle, Walk, Die}
var current_state : State
var direction : Vector2 = Vector2.LEFT
var points : int
var positions : Array[Vector2]
var current_point : Vector2
var current_point_position : int
func _ready():
	if patrol_points != null:
		points = patrol_points.get_children().size()
		for point in patrol_points.get_children():
			positions.append(point.global_position)
		current_point = positions[current_point_position]
	current_state = State.Idle
	
	
	

func _physics_process(delta):
	enemy_falls(delta)
	he_still_stands_but_with_animation(delta)
	finally_he_walks_hooray(delta)
	move_and_slide()
	
	
func enemy_falls(delta):
	velocity.y += 1000*delta
	
func he_still_stands_but_with_animation(delta):
	velocity.x = move_toward(velocity.x, 0, 1500*delta)
	current_state = State.Idle
	
	
func finally_he_walks_hooray(delta):
	if abs(position.x -current_point.x) > 0.5:
		velocity.x = direction.x*1500*delta
		current_state = State.Walk
	else:
		current_point_position += 1
	if current_point_position >= points:
		current_point_position = 0
	current_point = positions[current_point_position]
	
	if current_point.x > position.x:
		direction = Vector2.RIGHT
	else:
		direction = Vector2.LEFT

my enemy should move between two marker2d points, and if he reaches left point his direction switches to right, and if he reaches right point - his direction switches to left, but my enemy is just goes to default right direction and then falls off the ground, what’s wrong here?

Getting lost in your code, you don’t checking if enemy is grounded just pushing velocity.y += 1000*delta. You call idle and move method with no checking anything.

I don’t really know what is current_point_position, what is then position?

Most platformers will use ray cast to check if there edge of cliff to change direction.

You can use Prints for variables to check how they works.
