Clear the Path

Part of the Signals and Collisions section of Coddy's Godot journey. Lesson 18 of 27.

To remove every node of a kind, loop over the group and free each node:

for crate in get_tree().get_nodes_in_group("crates"):
	crate.queue_free()

You cannot free the list itself. get_nodes_in_group("crates").queue_free() stops the game with an error, because a list is not a node.

Three crates block the way to the right. They are all in the group crates.

Challenge

Medium

The switch removes only Crate1. Make it remove every crate in the group crates. Then walk through.

Try it yourself

extends Node2D

func _ready():
	$Switch.body_entered.connect(_on_switch_body_entered)

func _on_switch_body_entered(body):
	$Crate1.queue_free()

Test yourself
