Question

`
The distance that the enemy makes is equal to the detection area radius

Here is the enemy script

extends CharacterBody2D

var current_state = IDLE
var speed = 60
var player_chase = false
var player = null
var direction = Vector2.RIGHT

var health = 80
var player_in_attack_zone = false
var roaming = true
var can_take_damage = true
var enemy_alive = true

enum {
IDLE,
NEW_DIRECTION,
MOVE
}

func _ready():
pass

func _process(delta):
if Global.game_started == true:
deal_with_damage()
uptade_health()
if enemy_alive == true:
if roaming :
match current_state:
IDLE:
pass
NEW_DIRECTION:
direction = choose([Vector2.RIGHT, Vector2.UP, Vector2.LEFT, Vector2.DOWN])
MOVE :
move(delta)

		if player_chase : 
			position += (player.position - position) / speed
			if Global.player_alive == false:
				player_chase = false
			$AnimatedSprite2D.play("walk")
			if (player.position.x - position.x) < 0 :
				$AnimatedSprite2D.flip_h = true
			else :
				$AnimatedSprite2D.flip_h = false
		else :
			$AnimatedSprite2D.play("idle")

func _on_detection_area_body_entered(body):
player = body
if Global.player_alive == true:
player_chase = true
else:
player_chase = false

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

func enemy():
pass

func _on_enemy_hitbox_body_entered(body):
if body.has_method(“player”):
player_in_attack_zone = true

func _on_enemy_hitbox_body_exited(body):
if body.has_method(“player”):
player_in_attack_zone = false

func deal_with_damage():
if player_in_attack_zone and Global.player_current_attack == true :
if can_take_damage == true and health != 0:
health -= 20
$damage_cooldown.start()
can_take_damage = false
print("slime health = ", health)
if health <= 0:
health = 0
enemy_alive = false
$AnimatedSprite2D.play(“death”)
await get_tree().create_timer(1).timeout
self.queue_free()

func uptade_health():
var healthbar = $healthbar
healthbar.value = health

if health >= 100:
	healthbar.visible = false
else :
	healthbar.visible = true

func _on_damage_cooldown_timeout():
can_take_damage = true

func choose(array):
array.shuffle()
return array.front()

func move(delta):
if !player_in_attack_zone:
position += direction * speed * delta

func _on_wait_time_timer_timeout():
$wait_time_timer.wait_time = choose([0.2, 0.5, 1, 1.5])
current_state = choose([IDLE, NEW_DIRECTION,MOVE])

what is the problem here?
you failed to make it make a distance to the player with this code?

[tsukidraw36]

No. I wan’t the enemy to chase the player, but the enemy make a distance with the player when the player walk next to him, and this distance is equal to the radius of the enemy’s detection_area. I don’t know why but, in addition to that, as soon as the enemy appears, he heads towards the center of the map. It’s really weird

[tsukidraw36]

I would like to show you a video of the game so that you can understand the problem but when I want to import one, it tells me that this type of file is not authorized

[zdrmlpzdrmlp]

@tsukidraw36

d this distance is equal to the radius of the enemy’s detection_area.

try check the sprite position of this scene, either the player or the enemy, the node scene’s sprite and child shall be 0,0 position, else its position looks offset’d

[tsukidraw36]

Okay i’ll try but it’s not a visual problem,the problem is that the enemy is supposed to chase the player, but if the sprite was offset it would at least play the animation, but it doesn’t

[tomwjerry]

I think this is the problem:

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

Try multiply instead of dividing for example position += (player.position - position) * 0.1
You might also need to normalize the vector: position += (player.position - position).normalized() * 0.1

[tsukidraw36]

What means “normalize”? What does it change?

[newtodevelopment]

If you use two different positions, put them into a normal equasion without the “normalized” method, it can cause inconsistent enemy behaviour.
This would obviously only occur if the position changes.

Using normalized basically scales down the vector to a value of 1.
This might sound complicated, but for more help, just look into the presentation

[tsukidraw36]

@tomwjerry

position += (player.position - position).normalized() * 0.1

I tried and thank you very much it works ! But the enemy don’t chase the player… I made some other changes for make sure that the enemy don’t chase any other object :

func _on_detection_area_body_entered(body):
	if body.has_method("player"):
		player = body
		if Global.player_alive == true:
			player_chase = true
		else:
			player_chase = false


func _on_detection_area_body_exited(body):
	if body.has_method("player"):
		player = null
		player_chase = false

So now can somebody help me to make the enemy chase the player?

[tsukidraw36]

and here is a video of my game :

so as you can see the enemy don’t chase the player but he play the animation as if he were
the enemy is just walking very slowly to the right

[tsukidraw36]

I finally used pathfinding to make the enemy chase the player and it works !!!

(Thank you for 1.3k views)

[GreatNateDev]

i had the same problem becuase my guy wasnt on the dot make sure in the player sceen the player is in the top right conor of thr screen this:

not this:

basicly make sure the collision and sprite is on the char body 2d @tsukidraw36

[tsukidraw36]

Yes everything was already well centered. Thank you anyway
