Help

i’m making a remake of don’t touch the spikes! in godot to learn the engine.

when you touch a wall in my game, i want to send a signal from the player to the spikes to remove themselves, the spikes and player are in different scenes.

how to do this?

Ideally, you’d want your Spikes to be an Area3D that can detect the Player and remove themselves.
See my little demo:

This is the scene structure

This is player.gd script

class_name Player
extends CharacterBody2D

func _physics_process(delta: float) -> void:
	velocity = Vector2.RIGHT * 200.0
	move_and_slide()

spikes.gd

class_name Spikes
extends Area2D

func _ready() -> void:
	body_entered.connect(_on_body_entered)

func _on_body_entered(body: Node) -> void:
	if body is Player:
		queue_free()

it worked, thanks! i was thinking of sending a signal to the spikes when you touch a wall to delete them, but i think your solution is better.
