Keep getting Invalid index ‘0’ (on base: 'PoolVector2Array) on line 24 (indicated below)
onready var navigation = get_tree().get_root().find_node("Navigation2D",true,false)
onready var destinations = navigation.get_node("Destinations")
var motion
var possible_destinations
var path
export var minimum_arrival_distance = 5
export var walk_speed = 0.5
func _ready():
randomize()
possible_destinations = destinations.get_children()
make_path()
func _physics_process(delta):
navigate()
func navigate():
var distance_to_destination = position.distance_to(path[0]) <----Line 24
if distance_to_destination > minimum_arrival_distance:
move()
else:
update_path()
func move():
look_at(path[0])
motion = (path[0] - position).normalized()* (MAX_SPEED * walk_speed)
move_and_slide(motion)
func update_path():
if path.size() == 1 and $Timer.is_stopped():
$Timer.start()
else:
path.remove(0)
func make_path():
var new_destination = possible_destinations[randi() % possible_destinations.size()-1]
path = navigation.get_simple_path(position,new_destination.position)
func _on_Timer_timeout():
make_path()
Any ideas?
