Question

I’m making a top-down game, I need the enemy to follow the player, but for some reason he just flies off the map, As if touching the detection_area the player pushes the enemy out, what should I do?
Script:

extends CharacterBody2D

var speed = 25
var player_chase = false
var player = null

func _physics_process(_delta):
if player_chase:
position += (player.position - position)/speed

func _on_detection_area_body_entered(_body):
player = _body
player_chase = true

func _on_detection_area_body_exited(_body):
player = null
player_chase = false

Not immediately obvious what the issue is, but I would check using global_position rather than position. If your nodes do not share a parent, funk could be occurring.

If it is just that the direction is opposite to what you want, invert it.

So he just stands still.

As in
global_position += (player.global_position - global_position)/speed

Continues to fly away :frowning:

Can you try this?

position += (position - player.position)/speed

Now the enemy just goes down the map

10

goes down behind the map

11

But why are you not using velocity? Just do like this:

if player_chase:
    velocity = (global_position - player.global_position) * speed
    move_and_slide()

Give a second try if it does not work:

global_position += (player.global_position - global_position) * speed * delta
12

I’ll try now, I apologize for the unclear answers, for some reason the forum is lagging a lot

In the first case, it rests against the lower right corner of the room, in the second, it also flies up but in jerks

Means it goes at the the opposite of the player? Or just a random dir?

15

Previously, the player goes to the enemy and he flies to the upper left corner from the player, but now to the lower right, behind the player, It’s a pity I can’t upload a video to make it clearer

Last Try from me:

if player_chase:
    var direction = (player.global_position - global_position).normalized()
    velocity = direction * speed
else:
    velocity = Vector2.ZERO

if global_position.distance_to(player.global_position) > 10 or global_position.distance_to(player.global_position) < -10:
    move_and_slide()
17

It gives an error: Invalid access to property or key ‘global_position’ on a base object of type ‘Nil’

18

Oh I forgot that:

if player_chase:
    var direction = (player.global_position - global_position).normalized()
    velocity = direction * speed

    if global_position.distance_to(player.global_position) > 10 or global_position.distance_to(player.global_position) < -10:
        move_and_slide()
else:
    velocity = Vector2.ZERO
19

Same error

Do you removed the previous codes?

This is the whole codes in the physics process:

if player_chase:
    var direction = (player.global_position - global_position).normalized()
    velocity = direction * speed

    if global_position.distance_to(player.global_position) > 10 or global_position.distance_to(player.global_position) < -10:
        move_and_slide()
else:
    velocity = Vector2.ZERO

Да удалил, The error does not disappear
