how do i stop nodes from shaking with NavigationAgent2D

Question

the code:

extends CharacterBody2D
const speed = 200

@export var player: Node2D
@export var marker: Node2D
@onready var nav_agent := $NavigationAgent2D as NavigationAgent2D

func _physics_process(_delta: float) -> void:
    var dir = to_local(nav_agent.get_next_path_position()).normalized()
    velocity = dir * speed
    move_and_slide()

func makepath() -> void:
    if Golbal.marker_finder == 0:
        nav_agent.target_position = player.global_position
    else: 
        nav_agent.target_position = marker.global_position




func _on_timer_timeout():
    makepath()



func _on_area_2d_body_entered(body):
    if body.is_in_group("player"):

        Golbal.marker_finder -= 1



func _on_area_2d_body_exited(body):
    if body.is_in_group("player"):

        Golbal.marker_finder += 1

@spaceyjase - you can always copy/paste this to an answer and then Hide the original comment... That'd actually be preferable for the board, since the question does have an answer... :)

Answer 1

There's nothing here to stop the agent when it reaches its destination; likely the shaking is because it's constantly trying to move to another position that it never quite reaches, thus continues to make small changes and the cycle continues...

A way to stop this is to add something similar:

var distance_to_next_step = transform.origin.distance_to(dir)   
if distance_to_next_step < DISTANCE_THRESHOLD:
    return
