Need help checking collisions for a characterbody2d

Question

I need help with an object that can collide with the tile map but is deleted when the player touches it. It is a characterbody2d as of right now. The code below is what I have now.

extends CharacterBody2D

var speed = 5
var random1 = randf_range(-1,1)
var random2 = randf_range(-1,1)
@onready var animated_sprite_2d = $AnimatedSprite2D

func _ready():
pass

func _process(delta):
animated_sprite_2d.speed_scale = randf_range(.5,1.2)
var screen_size = get_viewport_rect().size
position = position.clamp(Vector2.ZERO, screen_size)
position.x += random1 * speed
position.y += random2 * speed
random1 += randf_range(-.1,.1)
random2 += randf_range(-.1,.1)
if random1 < -1 :
random1 = -1
if random1 > 1 :
random1 = 1
if random2 < -1 :
random2 = -1
if random2 > 1 :
random2 = 1

if random1 > .2:
	animated_sprite_2d.flip_h = false
if random1 < -.2:
	animated_sprite_2d.flip_h = true


move_and_slide()

func _on_area_2d_body_entered(body):
if (body.name == “player”):
queue_free()

to check collision from characterbody2d and if it collides with player, then queue free itself:

for i in get_slide_collision_count():
	var collision = get_slide_collision(i)
	if collision.get_collider():
		if collision.get_collider().name=="player":
			queue_free()

put the codes in func _physics_process(delta):

So adding a area2d to it and checking _on_area_2d_body_entered wouldn’t work?

[zdrmlpzdrmlp]

well it works, but you will need an extra area2d to check if the player enters it or not, this will be useful if you want to have a ranged area larger than the enemy body collision shape

[thepiglin83]

well that is exactly what i have and it is not working.

[zdrmlpzdrmlp]

because the area2d is the same size like the body collision shape? hence the player never enters it

[thepiglin83]

no matter how big the area2d is it doesn’t detect it. I am using this though so maybe thats where the problem is:

func _on_area_2d_body_entered(body):
if (body.name == “player”):
queue_free()

[zdrmlpzdrmlp]

well um, if the collision code works, then no need for this anymore
it also could be just your naming is not 100% precise, you sure the body that entered the area is named “player”?

[thepiglin83]

it is when i remove the if body name part it works though. it just instantly deletes itself.

[zdrmlpzdrmlp]

some other things could be entered it, that’s not player. try print(body.name)

That helped. I managed to fix it thanks so much!
