Here is a simple way to spawn enemies in godot 4. Here is the full game: https://averagegodotenjoyer.itch.io/space-monsters-in-space I built this game on a video in my channel take a look if you are interested.

Spawner Code

extends Node3D

#essetially just a counter @onready var current_level=0 #the level is the key the amount of monsters is the value @onready var monster_dict={ 1:1, 2:2, 3:4, 4:8, 5:30 }

#the monster we will be spawning in. @onready var monster=preload("res://Monster/MonsterGuy.tscn") #A random number genrerator to spawn from alternating spawn points. @onready var rand=RandomNumberGenerator.new() @onready var dead_enemies=0

func _ready(): add_to_group("level")

func enemy_death(): print("enemy death") dead_enemies+=1 if dead_enemies==monster_dict[current_level]: $InBetweenWaves.start() dead_enemies=0 get_tree().call_group("player", "award_points", 200)

func spawn_enemies(): for i in range(monster_dict[current_level]): var m = monster.instantiate() print("spawning enemy") #we check the amount of children on our spawn holder var spawn_length = $SpawnHolder.get_child_count()-1

then make a random number in that range

var rand_num = rand.randi_range(0,spawn_length) #We use that number to randomly select a spawner node position to use var spawn_postion = $SpawnHolder.get_child(rand_num).position #we add the monster as a child of the level #We set the monsters position to the spawn location m.position = spawn_postion add_child(m) #This is just a fast way to create a timer similar to wait in python await get_tree().create_timer(2.0).timeout

func update_level(level): match level: 1: print("its level one") #additional stuff here like announcer saying: Wave 1! 2: print("its level two") 3: print("its level three") 4: print("its level four") 5: print("its level five") spawn_enemies()

func _on_in_between_waves_timeout(): print("Leaving level: ", current_level) current_level+=1 update_level(current_level)

This is the code on the enemy script that calls the enemy death function. get_tree().call_group("level", "enemy_death") ... https://www.youtube.com/watch?v=cxUiWOUnywM
