Question

How would i make a chasing ai similiar to Ao Oni? i keep on trying to find videos but they are all not for 4.3.

If it helps, my player code is listed below.

extends CharacterBody2D

const max_speed = 600
const accel = 500
const friction = 600

var input = Vector2.ZERO

func _physics_process(delta):
player_movement(delta)

func get_input():
input.x = int(Input.is_action_pressed(“ui_right”)) - int(Input.is_action_pressed(“ui_left”))
input.y = int(Input.is_action_pressed(“ui_down”)) - int(Input.is_action_pressed(“ui_up”))
return input.normalized()

func player_movement(delta):
input = get_input()

if input == Vector2.ZERO:
if velocity.length() > (friction + delta):
velocity -= velocity.normalized() * (friction * delta)
else:
velocity = Vector2.ZERO
else:
velocity += (input * accel * delta)
velocity = velocity.limit_length(max_speed)

move_and_slide()
