Question

So I’m trying procedural generation with a ‘dungeon’ where each room have differents ‘exits positions’ and the main problem is that sometime, 2 rooms are generated and are overlapping. Of course I thought about Area3D. Each room have an Area3D being the soil but it doesn’t work. I tried putting on_area_entered() signal but nothing trigger it and I tried get_overlapping_areas() and nothing work either. I wanted to make the generation in a main gdscript file where each room are instantiate and then I look up for possible overlapping and if there is I try another evit position. please help I started yelling alone in the dark.

Could you show your generation code

@tool
extends Node3D

@export var generate_dungeon: bool = false : set = trigger_generation
@export var reset_dungeon: bool = false : set = trigger_reset
@export var attempts : int = 10
@export var nbRooms : int = 20

const ROOMS : Array = [
	preload("res://scenes/rooms/DungeonRoom_1.tscn")
]

var all_exits_positions : Array = []
var all_generated_rooms_areas : Array = []

func trigger_generation(value: bool):
	if value:
		update_preview()
		generate_dungeon = false

func trigger_reset(value: bool):
	if value:
		reset_preview()
		reset_dungeon = false

func _ready() -> void:
	update_preview()
		
func reset_preview():
	for child in get_children():
		child.queue_free()
		
	all_exits_positions.clear()
	all_generated_rooms_areas.clear()
		
func update_preview():
	reset_preview()
	generate_main_room()
	generate_rooms()
	
func generate_rooms():
	for i in nbRooms:
		var next_room = get_random_position()
		generate_room(0, next_room.global_position, next_room.global_rotation)
		

func generate_main_room():
	var main_room = generate_room(0, Vector3(0, 0, 0), Vector3(0, 0, 0))

func generate_room(index : int, position : Vector3, rotation : Vector3):
	var new_room = ROOMS[index].instantiate()
	
	add_child(new_room)
	new_room.global_position = position
	new_room.global_rotation = rotation
	
	var exits : Array = new_room.get_node("exits_folder").get_children()

	all_exits_positions.append_array(exits)		
	var area = new_room.get_node("SquareSoil")
	all_generated_rooms_areas.append(area)
	
	#print(check_collision())
	if check_collision(area):
		print("Overlapping")

func get_random_position():
	all_exits_positions.shuffle()
	return all_exits_positions.pop_back()

func check_collision(target : Area3D) -> bool:
	for area in all_generated_rooms_areas:
		print(area.overlaps_area(target))
		if area.get_overlapping_areas().has(target):
			return true
			
	return false

Ok I figured that Area3D are sh*t for my code. Instead I Used AABB with the basic constructor AABB(position, size) instantiate with my CollisionShape3D and with the intersects method. Works perfectly fine.
